General Introduction
2 General introduction
This document is the user and training manual of a FlexRip / FlexProof and is
intended for all operators. It explains a FlexRip workflow, the setup of possible
configurations, describes its daily use and contains some basic troubleshooting.
This document is currently available as PDF file or on-line help.
A FlexRip comes with the Suite 12 DVD that contains the following:
1. Software
2. User documentation on:
•
FlexRip / FlexProof (this document) (PDF file: Acrobat)
•
Esko Curve Pilot
•
Esko Screening
•
SambaFlex Screens
Warning
This document (and a FlexRip training in general) assumes that the operators of a FlexRip
are at least comfortable with the basics of the Windows operating system. A daily user of
FlexRip does not need detailed knowledge, but the system manager who controls the inhouse networking, installation and configuration of Windows does. This implies that he
should have no problems reading our installation and update documentation, written in
English. If this is not the case, Esko strongly advises the customer to have his system
manager follow a Windows training program.
Introduction to an Esko FlexRip workflow
3 Introduction to a FlexRip
workflow
3.1 What is a FlexRip?
1. A FlexRip is designed as a file RIP. There is no direct interfacing with nonEsko machines to ensure maximum connectivity, flexibility and
performance.
2. FlexRip is a true Dual Channel RIP. It is equipped with an Esko native
channel and an Adobe Certified PS/PDF channel to guarantee a fully open
platform.
3. The FlexRip engine is Esko technology and a continuation of the FastRip
technology. FlexRip has the same engine for all flavors.
4. FlexRip contains various output modules for different output device types
(proofers, ImageSetters, PlateSetters), but only 1 kernel to guarantee a 100%
consistency.
5. FlexRip comes standard with Esko Curve Pilot, the advanced calibration tool
for film output, plate calibration and press compensation.
6. FlexRip is based on a very modular design, so different output flavors can be
added at any time.
3.2 What kind of FlexRip flavors exist?
FlexRip is a modular product with different input channels and a variety of output
flavors.
Startup and shutdown of Esko FlexRip
1. Input channels:
•
•
PostScript 3 / PDF 1.4 / PDF 1.5 / PDF 1.6
Normalized PDF (Esko’s native file format)
Note
FlexRip 12 is compatible with Automation Engine 12, Esko PackEdge 12 and Esko Plato 12
for PS/PDF interpretation.
2. Output flavors:
•
•
•
•
•
•
•
•
•
FlexRip/Approval provides an interface with Kodak’s Approval proofer
machines.
FlexRip/B either rips on the fly (Esko native only) or rips to (screened
bitmap) files before sending the information to the Barco ImageSetter (PS
and Esko native).
FlexRip/C outputs screened LEN files for CDI’s.
FlexRip/DCS screened output is a generic module to generate DCS 2.0 files.
FlexRip/DCS unscreened output provides generic unscreened DCS 2.0 files.
FlexRip/P outputs (un)screened PDF or PostScript files.
FlexRip / FlexProof outputs to proofing devices. Various output formats are
available: TIFF, PS, RTL, PDF, Windows Printer, and E Printer. It can also be
used for output on digital presses (HP Indigo).
FlexRip/Tg (TIFF/Gray) outputs grayscale (8-bit) TIFFs (unscreened).
FlexRip/T4 outputs screened bitmap TIFF files (1-bit).
3.3 What is a FlexRip / FlexProof?
FlexRip Proofing Output is a module that outputs to various proofing devices.
This flavor is called FlexProof if installed on a dedicated PC.
There are different FlexRip / FlexProof output formats depending on the type of
device you want to proof on:
Windows Printer
FlexProof will generate a .PRN file which is formatted in GDI (Windows printing
language). The .PRN file is sent to a driver which converts the GDI information into
the printer’s native language. GDI (Graphics Device Interface) is a collection of
standard graphical functions provided by Microsoft Windows. Windows-based
applications do not access the graphics hardware directly, but instead, GDI interacts
with device drivers on behalf of applications.
The GDI functions allow Windows to control the way graphics are displayed and to
generate graphical output for displays, printers, and other devices. The printer
driver converts GDI objects into the printer language.
With FlexProof now generating GDI output, FlexProof can drive any proofer that
Startup and shutdown of Esko FlexRip
can be driven from Windows. All you need is a Windows printer driver to drive the
proofer from FlexProof.
Only a limited list of proofers will be supported:
1. HP:
•
•
•
•
•
•
HP5000 DesignJet (Simplex)
HP5500 DesignJet (Simplex)
HP20PS (Simplex)
HP9000DN (Duplex)
HP5SI LaserJet (Duplex)
HP8550DN (Duplex)
2. Epson 7600, 9600 and 10600
3. Xerox 7300
E Printer
FlexProof/E is a new flavor in FlexProof, which is the result of Esko’s co-operation
with EFI. Esko built in some of EFIʹs Best Color technology. FlexProof/E uses drivers
from the EFI’s Color Proof XF to drive the proofers in its native language, while
profile and color management is done fully using Color Engine Pilot and Esko Color
Management Module.
TIFF (Screened):
FlexProof will generate a composite CMYK TIFF file or (in case of a LATRAN
license) separate TIFF files: CMYK, Pantone or user defined separations. The image
is screened at printer resolution. The TIFF file can be passed on to any printer or
printer RIP that understands CMYK TIFF.
TIFF (Unscreened):
FlexProof will generate a composite CMYK TIFF file. The image is unscreened. The
TIFF file can be passed on to any printer or printer RIP that understands CMYK
TIFF.
PS (Screened)
FlexProof will generate a composite CMYK PS file. The PS file consists of a header
and an image. The image is screened at printer resolution. There is full PPD support.
The PS file can be passed on to any printer that understands PostScript.
PS (Unscreened)
FlexProof will generate a composite CMYK PS file. The PS file consists of a header
and an image. There is full PPD support. The image is unscreened. The PS file can
be passed on to any printer that understands PostScript.
RTL file
FlexProof will generate an RTL file. The RTL file can be passed to any printer that
understands this printer language. The following printers should be configured
Startup and shutdown of Esko FlexRip
using RTL: HP650c, HP750, HP755, HP2000, HP2500, HP3000, HP3500, HP800,
HP1055cm, SpinJet 1055, SpinJet 5000, Mutoh 6100 RJ, Agfa Sherpa 42, ENCAD
NovaJet, NovaJet Pro, and Kodak 3043.
PDF Screened
FlexProof will generate a CMYK PDF file. The file will be screened and can be
passed on to any printer that understands PDF.
PDF Unscreened
FlexProof will generate a CMYK PDF file. The file will be unscreened and can be
passed on to any printer that understands PDF.
Note
You will only see the output types you have a license for.

3.4 FlexRip basics
3.4.1 General PS and Esko native workflow
This is a general presentation of a FlexRip workflow:
3.4.1.1 PostScript workflow
In a PostScript workflow, the DTP operator (Macintosh or PC) will print an outputready job via the Print menu in the application. Using the printer driver of Adobe
PS and Esko's dedicated output device PPDs, the operator sets following job
parameters in the (separated) PostScript file:
•
•
•
•
•
•
the selection of separations to be printed
screening parameters: dot, screen ruling (lines per inch or lpi), angle
job size
DGC, Strategy (*.icpro) or CurveSet (*.prsync) Esko's compensation curves.
See the Esko Curve Pilot (page 83) chapter for a short introduction and the
dedicated Esko Curve Pilot documentation on the Suite 12 DVD for an indepth explanation.)
positive or negative; right or wrong reading
distortion (flexo-printing issue)
Some settings may be left out as they can be set default in a specific RIP queue
(e.g. expose resolution, output folder,...). The PostScript file ends up (via AppleTalk
print queue, Hot Folder,...) on the FlexRip and is ripped automatically, using default
or job-specific RIP options.
The output files will be written in a folder on the FlexRip PC.
See the flavor-specific workflows for more in-depth information.
Startup and shutdown of Esko FlexRip
3.4.1.2 Native workflow
As well as being an Adobe Certified PS3 and PDF RIP, FlexRip can also rip data
from all Esko PrePress applications without any additional calculation or processing
time, since the format used in the Esko PrePress applications is exactly the same
format used in the FlexRip. This enables an unrivalled level of throughput and
consistency.
You can choose to print to the FlexRip directly from Esko PrePress applications like
Esko PackEdge and Esko Plato and all output options can be set interactively. To
maximize throughput, operators can rip files via a ticket-driven workflow
(Automation Engine Server or FlexRip Pilot), offline from the graphical editors. Jobs
can be selected, assigned a ticket and then launched in the background, reducing
workstation time. Users can see the ripping progress of any job on either the Mac or
Windows PC. Logging information can be obtained.
See the flavor-specific workflows for more in depth information.
3.4.2 Which file formats can be sent?
As the FlexRip is a certified PS level 3 RIP, following file formats can be sent:
•
•
•
Separated PostScript: Level 1, 2 or 3.
PDF 1.3 – PDF 1.4 – PDF 1.5 – PDF 1.6
Esko's native file formats.
A normal PostScript workflow will only be based on separated PostScript, although
FlexRip can handle composite PS files as well. The PostScript interpreter of the
FlexRip will read composite PostScript, analyze it into separations and hand over
the data of each separation to the RIP, which will make 1 output file per separation.
However, customers that receive composite PDF files have to realize that errors may
occur when handling the files.
Separated PostScript files for a FlexRip were made with a specific FlexRip PPD.
Composite data may not be made via a FlexRip PPD and will probably miss some
RIP settings, like the correct screen ruling (angle, LPI, dot type), output name, etc...
Most of these then have to be set in the Dispatcher's queue settings. In the Screening
tab, you can define the missing screen ruling parameters or overwrite the ones that
are incorrect.
Note
In a PostScript workflow, Esko strongly recommends using separated PostScript as
standard and preferred input channel.
For FlexRip / FlexProof, separated Postscript files are required to maximize

consistency between plate/film and proof.

In general, DTP applications output their data in the description language
&quot;PostScript&quot; (PS). When the output has to be a color version (e.g. a proof), one will
write &quot;composite PostScript&quot;. This 1 file generally includes all the data, their color
attributes and their relation to each other. Output for a specific proofer will be done
using a PPD file (printer description) of that proofer, meaning that the PS file will be
adapted for that specific output device.
When outputting to a film- or platesetter (e.g. CDI), the job has to be delivered to the
RIP as a &quot;separated PostScript&quot; file. This means that all the data are already split up
per separation (ink). This is also 1 file, but now written in chapters ('pages'). Each
Chapter describes 1 ink. The RIP of the film- or platesetter will recognize these
&quot;chapters&quot; and handles each ink separately. The color information in this file is in
fact redundant info (the laser in the machine does not care about color); so each
'chapter' describes the separation in black.
Also PDF files may not contain the correct info. The correctness of the PDF files will
heavily depend on the applications that write the PDF files. Very common mistakes,
such as missing special colors or missing separation info (LPI/angle) are not
limitations of the PDF format itself but of the applications that produce these PDF
files. PDF files written from Esko applications such as Esko PackEdge, Esko Plato
and Automation Engine will contain the correct info.
3.4.3 Workflow description
In a FlexRip / FlexProof workflow, Esko-native data or separated PostScript files are
sent to a specific FlexRip queue.
The FlexProof workflow consists of the following steps:
•
•
•
•
•
A native Esko file is selected from the Pilot and sent to an FlexProof
Dispatcher
or a PostScript file is printed to the FlexProof
The Dispatcher produces separations (in CT format).
All separations are re-combined to a CMYK file (or an RGB file in case of
GDI).
The composite file is sent to the proofer directly or indirectly via a 3rd party
RIP.
Separations produced by the FlexRip can be re-combined by an Image Downloader
task on the server or by the FlexRip itself. Recombining separations on the server by
Startup and shutdown of Esko FlexRip
a separate task will result in an extra entry in the Automation Engine monitor and
will free up the Dispatcher as soon as the separations are produced, which can
result in a considerable speed improvement. For more information on the Image
Downloader task, please consult your Automation Engine manual.
Startup and shutdown of Esko FlexRip
Startup and shutdown of Esko FlexRip
3.5 Output file type
The output file type depends on the FlexProof flavor you have installed.
•
•
•
•
•
•
FlexProof/E: E printer uses drivers from the EFI’s Color Proof XF to drive
the proofers in its native language, while profile and color management is
done fully using Color Engine Pilot and Esko Color Management Module.
FlexProof /TIFF: generates a CMYK TIFF file from any separated PS file or
Esko native file and sends it to any installed printer that accepts TIFF files.
FlexProof /PS: generates a CMYK PS file from any separated PS file or Esko
native file and sends it to any installed PS printer.
FlexProof /RTL: generates an RTL file from any separated PS file, PDF, Esko
native file or set of screened files (like LEN files) and streams it to any
device that understands RTL like HP650c, HP750, HP755, HP2000, HP2500,
HP3000, HP3500, HP800, HP1055cm, SpinJet 1055, SpinJet 5000, Mutoh 6100
RJ, Agfa Sherpa 42, ENCAD NovaJet, NovaJet Pro, Kodak 3043.
FlexProof/PDF: FlexProof will generate a CMYK PDF file. The file will be
screened and can be passed on to any printer that understands PDF.
FlexProof/GDI: generates RGB bitmaps (Microsoft Windows printing
language) and is passed to a standard Windows driver which converts into
the Color space of the printer. The following printers are supported:
HP5000/5500 and Epson 7600/9600/10600.
3.6 What is a FlexRip Queue?
The heart of the FlexRip is a program called the Dispatcher. A Dispatcher controls
the RIP and manages input queues for one specific device. Queues receive the PS
data that were printed from the DTP station. The behavior of the queue ('how will it
rip') is determined by its 'settings'. Each queue can have different settings.
There are several queue types. The most common are:
•
An AppleTalk print queue (Macintosh)
•
A Hot Folder
•
A 'Named Pipe' queue (&quot;PC-talk&quot;).
•
An EskoLink queue
The FlexRip queue receives the data and rips it to a CT file according to its specific
settings.
Startup and shutdown of Esko FlexRip
4 Startup and shutdown of
FlexRip
4.1 Why and when?
In any normal FlexRip workflow, the FlexRip computer should never be shut down.
Even reconfiguring RIP queues does not require shutting down or rebooting the
computer.
So why shut down the FlexRip?
•
You expect a power failure.
•
You physically want to move the computer.
•
You have to open the computer (hardware service reasons).
Or why reboot the FlexRip?
•
The Windows software asks you to. This will often be the case when reinstalling Windows software or peripherals on the computer.
•
Some (Esko) service intervention requires to do so (changes to configuration
of the network, modem or display might require a reboot afterwards).
A Windows shutdown will automatically stop all running processes. This means
that also all running Esko programs will be stopped automatically. We do advise
you to separately stop all programs before rebooting or shutting down the FlexRip
computer.
As the FlexRip is made to rip, and the RIP itself is a client process of the Dispatcher
program, the most important program running on your FlexRip is the Dispatcher!
This will also be further explained in detail.
4.2 How to start up a FlexRip?
4.2.1 Start up the computer
The FlexRip computer is switched off.
•
•
•
•
Check the network cable.
Switch the monitor on.
Remove all floppy disks or CDs from their drives.
Press the power button (top-left on front panel).
Windows will make your computer boot automatically. If you are not familiar with
PC operating systems, never intervene during the boot process. The boot sequence
should end with a screen that has the window:
”Begin logon”
Startup and shutdown of Esko FlexRip
'Press Ctrl + Alt + Delete to log on'
If you wish to use the normal FlexRip software, log on as user ‘FlexRip' with
password ‘FlexRip'.
For FlexRip / FlexProof in a native (Normalized PDF and GRO) workflow (i.e. when
part of an Automation Engine configuration) this is mandatory, unless you mount
specific shares separately.
Only log on as user ‘Administrator’ for Windows system-management reasons or
to install software.
4.2.2 Starting up the Rip
Starting the Dispatcher program starts the RIP.
1. Start up the &quot;Dispatcher(s)” by double-clicking its desktop icon or by
choosing the right Dispatcher via Start =&gt; All Programs =&gt; Esko =&gt;
FlexRipProof 12.
2. Start up the 'Status Monitor' in the Tools menu in (each) Dispatcher.
3. Start up the 'History View' in the Tools menu in (each) Dispatcher.
More detailed info on these programs can be found further in their separate
sections: Status Monitor (page 72) and History View (page 75).
Note
Renaming the desktop icon can only be done in the FlexRip Configurator. See the FlexRip
Configurator manual for more information.
4.3 How to shut down a FlexRip?
4.3.1 Stopping the Rip
Closing the Dispatcher program stops the RIP.
Note
When stopping the Dispatcher program, it is always advisable to close its client programs
Status Monitor and History View first.
Startup and shutdown of Esko FlexRip
How to stop the Dispatcher:
•
Choose Exit from the Server menu and confirm by clicking Yes on 'Are you
sure? Or simply click the close button (top-right in the Dispatcher window)
and confirm with Yes on 'Are you sure? '.
4.3.2 Shutting down the computer
To shutdown the FlexRip computer:
1. Close all programs.
Other programs that could still be open:
•
•
Esko Curve Pilot editor
Text editors Notepad or WordPad
2. Start / Shut Down. Choose 'Shut down the computer' and click YES.
4.4 How to reboot the FlexRip computer?
•
•
Close all programs.
Go to Start / Shut Down / Restart the computer and click YES.
The computer will automatically shut down and restart again.
An overview of programs on the Esko FlexRip
5 An overview of programs on
the Esko FlexRip
5.1 General
Logged on as user ‘FlexRip’ (see next section for details on logon users (page 25)),
you will probably find at least 3 icons on your desktop that start up following
programs: the Dispatcher, Esko Curve Pilot (Esko’s Dot Gain Compensation editor)
and FlexRip Configurator 10. If you do not find any desktop icons go via Start /
Programs / Esko...
1. The Dispatcher is the 'heart' of the FlexRip. It is both the ‘daemon’
(continuous automatic process) that makes the RIP run and the place where
all queues and RIP options are set up.
Each output device requires a new Dispatcher. This means that if you make
files for 3 different output devices, you will have 3 Dispatchers.
Note
Note that each Dispatcher needs a separate licence.
2. The Status Monitor is a dedicated monitor of the Dispatcher processes. This
Monitor is opened from within the Dispatcher Tools menu.
It is recommended to activate the Status Monitor immediately after starting
up the Dispatcher. Starting up the Status Monitor after having launched a
job will not immediately show the actions of the job that is being ripped.
3. History View lists the finished processes and their log files. History View is
opened from within the Dispatcher Tools menu.
4. Esko Curve Pilot: this DGC (Dot Gain Compensation) editor offers you the
possibility to make the compensation curves that are necessary for specific
printing processes (e.g. flexo). The strategies (the curves, *.icpro files) will
reside on the FlexRip or the Automation Engine server.
Note
Esko Curve Pilot is further explained in a dedicated Esko Curve Pilot document that
can be found on your Suite 12 DVD.
Note
An overview of the programs on the Esko FlexRip
Automatic PlateMaking curves can be created in the FlexRip Configurator.
5. The FlexRipConfigurator allows you to add, modify or delete
configurations.
Note
You should be logged on as 'Administrator' to be able to use the FlexRip
Configurator.
5.2 Which logon to use?
•
When do you log on as user Administrator?
When you are installing or removing software or configuring your FlexRip
computer on Windows level (networking, connectivity etc).
•
When do you log on as user FlexRip?
In all other cases. All daily use of your FlexRip: the Dispatcher or its queue
management, Esko Curve Pilot, Esko Bitmap Viewer.
The following sections cover the Dispatcher (page 26), Status Monitor (page 72) and
History View (page 75) in detail.
Dispatcher
6 Dispatcher
6.1 General
The Dispatcher program is used for:
•
•
Starting and stopping the Rip
Setting up input queues and their Rip options
The Dispatcher is started by:
•
•
Double clicking the icon on the desktop.
Clicking Start ⇒Programs ⇒Esko /FlexRipProof 12 ⇒FlexRipProof Dispatcher.
This starts up the Dispatcher program itself, but also puts the actual RIP in an 'idle' status,
which means stand-by for action.
Warning
When the Dispatcher program is stopped, all ripping processes stop executing and the RIP
itself is stopped.
When an ongoing RIP process has to be stopped for some reason, then choose
'Abort job' from the Server menu. This stops all ongoing RIP processes, but leaves
the Dispatcher program alive. As soon as you send a new job to the RIP, the RIP will
start up automatically. When the Dispatcher is started for the first time, there will be
at least 4 queues visible, one of each standard type. FlexRip/B will start up with only
one queue, the EskoLink queue.
Dispatcher
6.2 Rip menu
The Server menu contains the following items:
1.
2.
3.
4.
5.
Clear History (page 27)
Send Job(s) (page 27)
Abort Job (page 28)
Restart PS Rip (page 28)
Exit (page 28)
6.2.1 Clear History
Choosing Clear history will delete all messages in the History View selection. You
will be asked to confirm first. As this deletes all entries in the history database, they
cannot be retrieved. This 'cleaning' will also delete the corresponding RIP log files.
Note
It is normally not necessary to clear this history database manually. In the Options menu
⇒ Program Options, you will be able to set a limit for the amount of history entries that
have to be remembered. If this number is exceeded, the oldest entries are removed
automatically.
Tip
It is advised not to enter a high number for the amount of history entries. The higher the
amount of entries allowed, the slower the History View and RIP logging will function.
6.2.2 Send Jobs
Click Send Jobs to open the 'Select and Send Jobs' dialog. Here you can browse to the
job you want to send.
Dispatcher
Note
This will only work if a Hot Folder is selected in the Dispatcher.
You can also right click the selected Hot Folder queue to make the Select &amp; Send Job(s)dialog
pop up.
6.2.3 Abort Job
As explained above, Abort Job stops the RIP (and as a consequence any current
ripping process). Remember that the RIP is automatically started again as soon as
another job comes in. You could choose to abort a job when you are sure you do not
need the output (e.g. you know the input file was wrong or a mistake was made in
the queue options).
Output files that were already generated by the RIP are not automatically removed.
6.2.4 Restart PS RIP
When Japanese fonts are downloaded, Restart PS RIP allows restarting the PS engine
of the RIP to activate the fonts in the RIP.
6.2.5 Exit
This will stop the Dispatcher program (and the RIP). Clicking the close button of the
Dispatcher
Dispatcher dialog will have the same effect. You will be asked to confirm first.
6.3 Options menu
The Options menu contains the following items:
1.
2.
3.
4.
Program Options (page 29)
Queue Defaults (page 31)
Performance (page 31)
Rip Priority (page 31)
6.3.1 Program options
The program options are general Dispatcher settings. They can be set per
Dispatcher.
Dispatcher
6.3.1.1 FlexRip Log Files
You can decide here whether or not you want the RIP to create log files. They can be
interesting to find out what happened if something went wrong. It is advised to
always create log files. Log files can be viewed in History View and are physically
located in the Logging folder.
C:\Esko\bg_data_FlexRipproof_v120\proof\LOGGING.
6.3.1.2 Automation Engine Server Disk Mounting
Enable Dispatcher mounts disks unless specifically mentioned otherwise.
6.3.1.3 Trace messages and History
•
•
•
•
Save Dispatcher Messages. It is advised to activate this toggle. 'Trace
messages' keep track of the general status of the Dispatcher. Esko will only
consult these in case of problems.
Number of files used indicates the maximum number of trace files that will be
stored.
Maximum number of messages in each file indicates the number of entries that
will be stored in one and the same trace file.
Number of entries in History indicates the number of log files History View
will show you. The number of entries in the History can be set as wished.
500 will probably be enough. This means that when entry number 501
appears, entry number 1 will be deleted.
6.3.1.4 Input Queue Settings
•
Include Debug Options: When checked, an extra tab sheet in the default queue
settings will appear: 'Debugging'. Please activate this Debugging (page 65)
tab, because it enables you to control the contents of the log files. This is
especially interesting for fast troubleshooting by customer services. They
will advise you which settings to change in order to speed up problem
solving.
•
Include Tuning Options: Should not be active (again unless Esko Customer
Service asks you to activate it).
Enabling the Tuning options makes a number of extra tabs appear in the
Queue Settings:
•
•
CopyDot Tuning (page 67), which is explained further on.
LineWork Tuning
Dispatcher
•
•
Contone Tuning
Memory Tuning
Note
Linework, Contone and Memory Tuning are specific tabs for our Customer Service
department and may only be used to solve or find a workaround for a specific
customer workflow or FlexRip problem.
•
Units: Can be set to INCH, CM, MM or MIL (1000 MIL = 1 Inch).
6.3.1.5 Advanced
Capture PostScript file: This should not be activated unless Esko Customer Service
asks you to. When activated, then after ripping every PostScript file together with a
lot of extra information will be stored in a special folder as an extra text file. This is
not the same as keeping the PostScript file in a Hot Folder after ripping! See further
in the appendix: Some classic errors and their explanation (page 87).
6.3.2 Queue defaults
A FlexRip can have several queues of:
•
•
different types
the same type
Each queue will have its own settings (how to rip, where to write the output file…).
The settings in Queue Defaults however are valid for all queues. We refer to the
Queue Settings (page 43) chapter for more details on queue settings. (The different
tabs look exactly the same).
The priority of the settings (page 43) is described further on.
6.3.3 Performance
This panel was used to overrule the default scheduling behavior of the Windows
operating system. Recent Windows versions do this very good by default, so we no
longer allow to overrule this.
Dispatcher
6.3.4 Rip priority
This field allows you to set the priority of the ripping process over other processes. You
might for instance have noticed that changing queue settings (working with the interface of
the Dispatcher) is very slow when the FlexRip is ripping at that same moment. That is
because the RIP process (the kernel) had all the priority. Now, some customers will want to
use applications on the FlexRip a lot (working with Dispatcher, Esko Curve Pilot, and Esko
Bitmap Viewer) and some almost never. The recommended setting is Normal.
6.4 Tools menu
The Tools menu contains the following items:
1. History View (page 33)
Dispatcher
2. Status Monitor (page 33)
6.4.1 History View
The Dispatcher program itself will not show you the list of actions that are finished.
History View will. All further info on the History View (page 75) program can be
found in a separate section.
6.4.2 Status Monitor
The Dispatcher program itself does not show any detailed information on the
ripping action. The Status Monitor program of that Dispatcher will show you more.
All further info on the Status Monitor (page 72) can be found in a separate section.
6.5 Info menu
The Info menu contains the following items:
1. Ports (page 33)
2. About Dispatcher (page 33)
6.5.1 Ports
The Dispatcher is the server program of the Status Monitor and History View
programs. The Dispatcher ports are used by its client applications to be able to
communicate with the Dispatcher. Technically they are TCP/IP socket port numbers.
6.5.2 About Dispatcher
Shows the date and version number of the Dispatcher program. This is useful
information when reporting some problem with Dispatcher. It is NOT the version of
your FlexRip software (see FAQs).
Dispatcher
6.6 Connected monitors
The Tools menu allows you to start up a History View or Status Monitor of that
(specific) Dispatcher. Both are actually client processes of that Dispatcher and count
for a 'connected monitor'.
As there is no need to start up a History View or Status Monitor a second time, you
will mostly see that the number of connected monitors is 2. If you see a number over
2 then you probably already started up these client programs and 'minimized' them.
This indicates that this number is only there for your information.
6.7 Input queues
First we have a short look at the possible queue types and then a closer look at their
settings.
6.7.1 Possible queue types
•
AppleTalk: From Snow Leopard onwards (Mac OS X 10.6), AppleTalk is no
longer supported on Mac. The preferred solution now is to use Esko Shuttle
functionality to directly send files to the EskoLink channel of the Dispatcher.
•
Hot Folder: A FlexRip Hot Folder is a folder on the FlexRip station that is
mounted/shared (made visible) to other computers on the network. The DTP
operator will print 'to file' and save the file directly in this Hot Folder. See
also the section in the appendix 'How to mount FlexRip volumes on a
Macintosh? (page 111)'.
•
Named Pipe: From Windows Vista / Windows Server 2008 onwards, our
Named Pipe workflow no longer works (as it relies on an Adobe kernel
printer driver, and kernel printer drivers are no longer supported). The
preferred solution now is to use Esko Shuttle functionality to directly send
files to the EskoLink channel of the Dispatcher.
•
EskoLink: ‘EskoLink (or previously ‘BarcoLink’ or 'DigiLink') is a queue that
represents a link with an Esko Server (Automation Engine or FlexRip Pilot).
This kind of queue will ‘receive’ RIP requests for Esko native files.
6.7.2 New - Queue Info - Delete
Should you have deleted the only queue of a specific type, (e.g. you deleted the only
AppleTalk queue present) then click the line below the other still existing queues (so
Dispatcher
no specific type is selected), and then click ‘New’. The Create Queue window will
pop up, allowing you to select a particular type of queue.
These three types of queues are PostScript channels. They cannot be used for Eskonative files.
For an AppleTalk queue you can only set the name and priority. Two situations are
possible:
1.
You create a new queue that is a copy of an existing queue. Here you can either
use the queue settings of the queue copied, or you can take the default queue
settings. Activate or deactivate the toggle to specify your choice.
2.
You create a completely new queue.
Dispatcher
The default queue settings option is greyed out, since these settings will
automatically be taken. As this queue is no copy of an existing one, no settings can
be copied.
For Hot Folder queues, apart from the name of the queue, the folder also has to be
set up. For more information, see the next chapter: General (page 37).
For Named Pipe queues, two situations are possible:
1. You create a new queue that is a copy of an existing queue.
Here you can either use the queue settings of the queue copied, or you can
take the default queue settings. Activate or deactivate the toggle to specify
your choice.
Dispatcher
2. You create a completely new queue.
Please give it a short name, preferably in one word: e.g.: Flexpipe.
The default queue settings option is greyed out, since these settings will
automatically be taken. As this queue is no copy of an existing one, no settings can
be copied.
6.7.2.1 General
Dispatcher
1. Name:
Give your Hot Folder queue a logical name. The operators will then have a
clear idea what the nature of the output will be. As seen in the above
graphic: the name of the Hot Folder already shows that the file is ripped at
2000 ppi. So it is advisable to 'summarize' in the name of the queue the 'hard'
queue settings that influence the output (as these queue settings will
overwrite the settings in the PostScript file).
2. Folder:
Type in the correct path of the folder on the FlexRip that will serve as Hot
Folder.
Note
Create the actual Hot Folder (using Windows Explorer) before you start creating the
Hot Folder queue.
Dispatcher
Note
On Windows level, you could delete a folder that is used by a Dispatcher queue as
the actual Hot Folder. When this happens, the Dispatcher will detect that the
construction of this Hot Folder is no longer valid. When you consult its 'queue info'
and click ‘OK’ following warning will appear:
&quot;New Folder&quot;
The Folder 'name' does not exist.
3. Activate:
Checking the box activates the folder as Hot Folder. A de-activated Hot
Folder will not rip incoming files automatically.
4. Scan Interval:
This indicates the period after which the Dispatcher checks the Hot Folder
for incoming files.
Note
If you are scanning Hot Folders over the network, you should decrease the frequency
of which the Hot Folder is scanned, otherwise you might create unnecessary network
activity. In other words, if your Hot Folder does not reside on the FlexRip, increase
the number of seconds.
5. Queue Priority:
The RIP will (only) consult the priority settings when several jobs are
waiting to be ripped. While the first job is being executed the RIP will
consult the queue priority setting to decide which one to rip next.
Example:
When the RIP is processing a job in queue A, and both queue B and C have a job
waiting to be ripped, then the queue with the highest priority settings will have its
PostScript file ripped next (e.g. B has priority 3, queue C has priority 2. When queue
A has finished, the job in queue C will be next).
6.7.2.2 File handling
1. Trigger on file type:
Select the file types you want the Hot Folder to trigger on and put them in the
'Trigger on File Type' column. Move the extensions from the right to the left
column by clicking the &lt;&lt; button. If you do not specify file types in the 'trigger'
column, the RIP will start up for any incoming file, regardless if this file can be
processed or not.
PDF* stands for all types of Esko PDF Native files (PDF, PDFPLA, PDFSTA,...)
2. Keep files with unknown file type for x seconds in Hot Folder:
File types you told the Hot Folder not to rip are best not kept in that Hot Folder.
Dispatcher
These unknown file types will be moved automatically to the subfolder named
'error'. Determine after how many seconds you want them to be removed. The
maximum value here is 1800 seconds (30 minutes).
3. Remove file after imaging:
When the option is not activated, the PostScript file will stay in the Hot Folder
after it has been imaged (in an appropriate subfolder named 'OK'). If you want
to use the same PostScript file for imaging on other devices via other FlexRip
flavors you should not activate this box. If it is active the PostScript file will be
deleted and you will need to make a second PostScript file for the other devices.
Note
This is only about known files that have actually been ripped. Not having these
removed (deleted) after ripping means they will be automatically moved to the subfolder
OK or Error.
4. Take Drag &amp; Drop Files:
makes it possible to drag and drop files onto a Hot Folder that is defined in the
FlexRip Dispatcher. It is also possible to select and send an (E)PS/PDF file to a
Hot Folder from the FlexRip itself. Checking the 'Take Drag &amp; Drop Files' box
prevents you from actually having to drop the files into the defined Hot Folder
before the file would be ripped. Files can be selected from any folder visible
from Windows Explorer. To activate this mechanism:
1.
2.
3.
4.
Click the Hot Folder to highlight it.
Click Queue Info.
Activate Take Drag and Drop files.
Click OK.
Note
It is only possible to activate this 'Take Drag &amp; Drop files' feature for 1 Hot Folder at a
time.
To select (E)PS/PDF files to be ripped on this Hot Folder using the Windows
Browser:
1. Click the Hot Folder to highlight it.
2. In the Dispatcher, select Send Job(s) from the Server menu or click right and
select Send Job(s) from the pop-up menu..
3. Browse to the job(s) and click Open.
The selected files will be copied automatically to the Hot Folder and will be
ripped normally.
5. OK/Error Folders:
Dispatcher
The settings above allow you to either keep the incoming files after ripping or to
remove them. If you decide that files should be kept after ripping it is advised to
define exactly to which folder you want them to be moved. Per Hot Folder, 1
folder can be specified for all files that went through the FlexRip successfully
and another folder for those files that errored out or were aborted by the user.
To define these folders:
1. Click the Hot Folder and click the Queue Info button.
2. Now click the OK/Error Folders… button
Note
This button will be greyed out when the Remove file after imaging option is
activated.
3. Select 1 folder for the files that went through the FlexRip successfully (OK
folder) and 1 folder for the files that errored out or that were aborted by the
user (Error folder). Note that before you specify the folder of your choice, the
default folder is defined.
Note
It is advised not to put the processed files in the Hot Folder.
4. When specifying the folder name you can browse to it or you can type in the
name of your folder. If the folder you specify does not yet exist the system
will ask if it needs to be created.
Note
These fields cannot be left blank.
Dispatcher
Queue Settings
7 Queue Settings
Many of the settings that are explained hereafter can also be set as print options can
be set in the Automation Engine or FlexRip Pilot for Esko-native workflows and in
DTP applications for PS/PDF workflows. But then, which settings will the RIP take
into account? What if opposite settings occur? And what if options are not set? The
next section explains how different settings interact.
7.1 Priority of settings
When an operator has set specific options, the file ends up in a Dispatcher queue
that also has its specific queue settings, and possibly also extra settings in the
'default settings' window. Which RIP settings will then be taken?
This is the order of how the RIP consults the settings:
1. FIRST: Dispatcher: specific Queue Settings. Queue settings will overrule all
others. Settings you always want to apply should be set here. See the section
'Workflow: flavors and hints' for an important remark on the settings 'image' and
‘emulsion’!
Note
Options that are set in the Dispatcher Queue Settings will be greyed out in the server
tickets.
2. SECOND: settings in the ticket or PostScript file. On this level you can set the
options that are job-related. In an Esko native workflow, the settings in the ticket
will be taken. In a PostScript workflow, settings in the Print menu, using the
correct PPD, will be used.
3. THIRD: Dispatcher: (menu 'options') Queue Defaults. Queue Defaults are
settings that apply to all queues. The RIP will only consult them if options are not
set in the Dispatcher or the ticket/PostScript file. This means that they are only
executed in case there is still a &quot;none&quot; setting to be answered! If a “none” settings
is still not answered by the Queue Defaults, the default setting inside the FlexRip
software will be taken.
Tip
To set up a logical workflow, it is advised to set the options that are always applicable as
high in the order as possible as these will overwrite occasional mistakes in ticket or print
settings.
Example
You always want to expose on a device at 2000 DPI. Then enter the resolution setting in
the Queue Settings. As soon as a setting is required only from time to time, you might
consider:
Queue Settings
• to put it in the name of the (newly made) specific queue.
• to leave the (default) queue settings on 'none' and specify it (each time when
wanted) in the ticket or PostScript file.
Note
A number of options, like output path and (scr)dgc can also be set in the FlexRip
Configurator. These settings will overrule all settings mentioned above! To make you
aware of Configurator settings, options that are set in the Configurator aregreyed out in
the Dispatcher, ticket and Queue Defaults.
7.2 Basic
The Basic options allow you to decide on how the output should look.
Queue Settings
Warning
Do not enter 0 (zero) in a value field. It will be considered as a 'hard' value and possibly
overwrite others! Leave the value field ‘empty’ before clicking OK.
7.2.1 Output module
This shows the type of Output module this specific Dispatcher was made for. Each
Dispatcher is based on a specific ‘fid’ file. A fid file describes a machine type
(device, printer description), which is why specific resolutions and size options will
appear in the dropdown lists.
7.2.2 Rotation
For PS/PDF (Hot Folder, AppleTalk or Named Pipe) or native input it is possible to
preset a rotation.
7.2.3 Scale
Scale options can be used for real job scaling (whole job at 50 %) or for the flexo
distortion factors (e.g. Horizontal: 0.982 - Vertical: 1). It is advised not to set the
distortion factor here (leave the fields blank!) as it is rather job-related and it is
easily set in the PostScript file settings when printing from the application or in the
setting options in the Automation Engine or FlexRip Pilot ticket.
Warning
If no scaling is required, then do not enter '1' as any value here will be seen as an actual
queue setting that overrules all others. It is advised to leave this field blank.
What if I printed Transverse?
Or in other words, what if the job is rotated in the RIP? The H and V seen here are
still the H and V as you ‘see’ in the job when viewed in the application. Scaling
factors have to be a value ranging between 0.000 and 2.000 (between 0 and 200 %). It
is not possible to set a value for one direction and leave the other value field blank.
This means that if you want a vertical scaling of 96,7 % you have to enter 0.96700 for
Vscale and 1.00000 for Hscale.
Queue Settings
7.2.4 Imaging options
7.2.4.1 Reverse
If you want your file to be reversed (negative-positive), set the Reverse option to
'Yes' or 'No'.
7.2.4.2 Mirror
Set the mirror option if you want the job to be mirrored.
Warning
LEN files are already mirrored by default. So if you want to proof LEN file readable, you
have to switch on the option Mirror. This behavior is consistent with ShowCT and Bitmap
Viewer Standalone.
The behavior of the program concerning the Mirror option is consistent with the
Esko Bitmap Viewer. This means that if you don’t set the mirror flag, the job will be
proofed readable, only when it is shown readable in Esko Bitmap Viewer.
7.2.4.3 Copies
Indicate how many proofs you want to output.
The RIP will only rip once, but the resulting file is submitted a number of times
to the printer.
Queue Settings
7.3 Output
7.3.1 Location &amp; Name
7.3.1.1 Output location
The location of the output folder(s) for the temporary output files is free to choose. It
is logical to define the output folder(s) on a hard disk with enough space available
(often drive D:\ on a FlexRip).
Note
Remember that this chapter concerns the output location of the temporary Monochrome CT
files, not the final output file that is sent to the printer. The actual output for the printer is
defined in the FlexProof Setup.
Tip
If you want several output folders, then it is a good idea to create them under one general
Queue Settings
output folder. So, after making the top folder visible to other computers, any new folder
under that top folder will automatically become visible as well.
Note
There are different places where you can specify the required output location. If the output
path is specified in the FlexRip Configurator (which has the highest priority), the output
path will be greyed out in the Dispatcher, ticket and Queue Defaults.
Example
D:\output
Is the 'top' folder
This folder is not used as a real output folder.
D:\output\komori_urgent
D:\output\komori_normal
are actual output folders that contain the output files. The operator will already see
which output files are urgent and on which plate type they should be imaged.
Note
Select the actual folder by using the Browse button, before filling in its path here.
7.3.1.2 Output file name
Note
This option is not applicable to FlexRip/Approval and FlexRip/B.
Here you can specify the name of the output file.
It is possible to use template variables, as explained below.
Template variables
All variables listed below must be specified between left and right angle brackets (&lt;&gt;). The
variables currently supported are:
•
&lt;file&gt; (name of the file that is sent to the FlexRip)
For the Esko native input this equals the job name of the PDF native (PDF,
PDFPLA, PDFSTA, etc.) file name.
For PS input this equals the name found for %%Title in the PS file.
Note
If no name is found in the PS file, 'Unknown' will be taken.
•
&lt;ink&gt;
This indicates the color group + underscore + full ink name
e.g. pms1000c_warmred
Warning
Queue Settings
This variable is not supported for FlexRip / FlexProof.
•
&lt;sink&gt;
The short ink name will be used. For process colors this means e.g. C instead
of cyan. For Pantone colors this means the PMS number or a shortened name
like WAR for Warm Red.
Warning
Designer colors will still be shown with their full name preceded by the letter 'D'.
Warning
This variable is not supported for FlexRip / FlexProof.
•
&lt;nink&gt;
The number of the ink will be used, based on the ink table in the original job.
•
&lt;page&gt;
For Esko-native input, this variable will add the page number to the output
name in case of a multipage document. In separated PS files every separation
is a page. This means that for a job with 6 inks the separated PS file will
contain 6 pages. For a multipage document you will get 6 pages for every
page in the document. For PS input this variable will add the correct page
number to the output file name when using FlexRip / FlexProof (composite)
output. For all monochrome flavors (B, C, TG and T4) the page number of
the PS file will be used. This explains why e.g. the output file name for the
4th separation of the first page of the document will get page number four.
•
&lt;date&gt;
This variable will add the date of ripping in numbers to the output file name.
The format is 'yearmonthday' (yyyymmdd). E.g. September 25 2003 will be
20030925'.
•
&lt;time&gt;
This variable adds the time of ripping in numbers to the output file name.
It is also possible to give a hard name in the 'Output file name' input field or
combine variables with fixed elements.
Some characters are not allowed in the 'Output file name' input field. The
following characters will automatically be replaced by an underscore ( _ ): \ ,
/ , : , * , ? , “ , &lt; , &gt; , |.
Queue Settings
Examples of templates
Without merging
A Normalized PDF file called 'sunshine' has 7 separations (CMYK, 2 Pantone inks
and one designer ink) and is sent to the FlexRip EskoLink queue which has the
following template:
The name of the output files will be as follows:
sunshine_Dave_$123.tif
sunshine_Dave_$C.tif
sunshine_Dave_$Dblue sky.tif
sunshine_Dave_$K.tif
sunshine_Dave_$M.tif
sunshine_Dave_$WaR.tif
sunshine_Dave_$Y.tif
The fixed element could be used e.g. to specify the name of the operator (in this case
Dave).
With merging
Let's assume we have two files. One called 'sunshine' which contains one page and a
second file called 'moonlight', containing two pages. The template has been changed
to include the page number in the output file names and the file is sent via the
merge queue to optimize the film:
Cyan and Warm red from 'sunshine' will be merged with Magenta and Pantone
123 from 'moonlight'. The name of the output file will be as follows:
sunshinemoonlight_Dave_P12$CWaRM123.tif.
The names of the jobs are merged while inks and/or pages are concatenated.
Queue Settings
7.3.1.3 Restricted file names
When activated, the names of your output files will be restricted to names that will
not give any problems in the VMS operating system. This basically means that all
characters that are not letters (abc) or numbers (123) or underscores (_) will be
replaced by underscores. So if you are not writing these output files on a VMS
computer, you do not have to activate this option.
Example
$#@^%!&amp;-will all be replaced by _ (the underscore)
7.3.2 Properties
7.3.2.1 Compression algorithm
Select the appropriate algorithm from the dropdown list. Choose between LZW,
PackBits, Uncompressed and None.
7.3.2.2 Enable Anti-aliasing
Anti-aliasing is relevant for the line-art objects in the design that require pre-processing to
CT. Enable anti-aliasing to smoothen the staircase effect in the generated CT for line-art
objects that need pre-processing.
7.4 PS/PDF Input
Please note that the PPDs used in FlexRip 5.2 will not work in FlexRip 12!
Queue Settings
7.4.1 PostScript
7.4.1.1 Screen type
Enable the appropriate screen type. You can choose between: Esko Classic,
DynaCell, PostScript or none.
•
Esko Classic (Precalculated) means that the aspect, the form, the rulings and
the angles of the screen are pre-defined in the Esko screening labs. These
screens are the result of advanced engineering work. The screens are
optimized for a smooth aspect, good behavior on the different printing
processes, lack of artifacts etc. Furthermore, the screens are designed
following a system of screen angles that avoids moir&eacute; between the main
colors (cyan, magenta and black). The use of precalculated screens allows
supporting advanced screening features like stochastic screening (Monet
Screens) and transitional screening (SambaFlex Screens). Precalculated
screens have only one disadvantage: since they have been designed and
Queue Settings
tested one by one, there is only a limited number of them available.
Although the total number exceeds 2000 different screen ruling/angle/dot
shape combinations, it is very well possible that no precalculated screen is
close enough to a customer's wish. This happens specifically when other
angles than flexo or offset angles are demanded. A typical example is silk
screen printing where unusual angles and screen rulings are used to avoid
clashes with the silk screen mesh. Esko DynaCell technology was developed
particularly for this purpose (see below). The pre-calculated sets are also
made to provide maximum protection against moir&eacute;. For more information,
please check the Screening manual.
•
Using PostScript screening implies that all the information needed to build
up the dots has to be in the PostScript file. Combining PostScript screening
and Esko-Graphics screening in the same file and/or separation is only
possible using the optional ScreenFilter application. Please see the
documentation on the ScreenFilter for more details.
In every DTP application, you can choose the LPI from the Esko PPD or you
can overrule it. Also the print angle will be offered by the PPD but the DTP
applications permit you to enter other angles. If you send these data to the
RIP, the 'Esko screening' setting will again change these values via its own
'jump-to' mechanism. This means that the RIP will automatically jump to the
nearest LPI or angle that is supported. If you do not use 'Esko screening' but
'PostScript screening', these 'special requests' will indeed be realized by the
FlexRip.
If you activate PostScript screening, the dot shape should also be described
in the PostScript file. If you cannot select dot shapes in your DTP
application, then it will probably describe the standard Fogra Round dot
shape (see also Esko's Fogra Round).
Why ever use this?
You could for instance use this if you insist on some 'exotic' angle. With
exotic we mean an angle which is not standard in flexo/offset. If you need an
angle of 3 degrees, then this is the only way to get it in the output file. Then
of course you will be limited to the dot types that your DTP application
offers you (to write in its PostScript output).
•
If the DynaCell license is available, this FlexRip option allows the operator to
specify any angle or lineature combined with Esko screening. It is
particularly useful for screen printing. DynaCell differs from Esko Classic in
that it doesn’t use sets of precalculated screens. Because of this, DynaCell
offers no protection against moir&eacute;. Esko Classic screening does, as this
screening only allows moir&eacute; free combinations of resolutions with LPI and
angles.
For more information on DynaCell, please consult the Screening manual.
Note
Because of the nature of Monet screening and SambaFlex screening it will not be
Queue Settings
possible to use DynaCell technology with these two screens. If DynaCell is selected
together with one of these screens an error will be generated at rip time.
7.4.1.2 Screen Swap Table
Note
The Screen Swap Table option will only be activated if screened data is output.
ScreenFilter allows you to define screen swap tables so that when files, containing
e.g. PS dot shapes, come into the Esko system the information of the screening is not
lost.
1. In the Screens part
, all detected, but unregistered screens appear. You
can register them and use them to define screen swap tables.
2. In the Screen Swap Table part
, you define screen swap tables, these can
be used in other applications, such as Esko PackEdge, Esko Plato, FlexRip,
Automation Engine, ...
For more information on how to create ScreenFilter rules, please refer to the
ScreenFilter documentation.
Note
Selecting (none) creates an EskoFlexRip v5.1 like situation.
7.4.1.3 Pure black overprint
Set the overprint mode for objects containing 100% black only. Possible Pure Black
overprint modes are:
•
•
•
No: no overprint is forced on an object containing 100% black, which means
that the situation is as is defined in the job.
Yes: forces PostScript overprint for objects in 100% black.
None: the default Queue settings will be consulted.
Queue Settings
7.4.1.4 Enable optimization
Should be set to ‘Yes’.
Example
Esko's RIP kernel will see to it that the vignette quality is enhanced.
Note
This optimization is not relevant when the vignettes are described as CTs in the PostScript
file (as is mostly the case with ArtPro jobs).
7.4.1.5 Preserve Quark trapping
If set to 'Yes', the Preserve Quark trapping option forces the system to keep the trap
strokes made by QuarkXpress.
7.4.1.6 Ignore PS color management
Images can be saved in PhotoShop in EPS format using an option 'Use PostScript
Color Management'. The result of this operation is that the resulting EPS file
contains information that the pixel values are not simply RGB or CMYK but are to
be interpreted by the receiver as a CIE-ABC or CIE-DEFG image and that the
receiver should reconvert that image to it’s own Color space using a PostScript
CRD.
In most cases this 'Use PostScript color management' option was set by accident and
the image retoucher did not intend that his carefully retouched image would be
reconverted from 1 color space to another changing all the separations. When this
option is off, PostScript color management is applied and the image is run through a
CRD, if this option is off the original data is interpreted as deviceRGB or
deviceCMYK even if the EPS file specifies that PS color management should be
used. Remark that PS color management is always used for Lab images even if this
option is switched on.
This means that if this toggle is checked, the color management that would be
applied to included PhotoShop EPS images will be ignored.
7.4.2 PDF
7.4.2.1 PDF password
In case you send PDF files that include a password, unlock them by entering the
password here.
Queue Settings
7.4.2.2 Ignore calibrated Color spaces
When this toggle is checked, FlexRip will ignore [CIE based] calibrated Color spaces
and will replace them by their regular device-independent counterparts.
The color of objects like lineart and images can be defined using a calibrated Color
space. This can happen because the objects already have a color in a calibrated Color
space before distilling or they can acquire a color in a calibrated Color space during
distilling process. This is not always intended behavior and the 'Ignore Calibrated
Color space' option will ignore the calibrated Color space of such objects when
converting the file to GRS. A typical example is that when you have black objects in
a calibrated Color space, you risk ending up with CMY color components if you do
not ignore the calibrated Color space.
7.4.3 Images
7.4.3.1 Abort for images with scaled resolution below ... dpi
Checking this toggle makes sure a resolution check on incoming images is
performed. This option offers you the possibility to get the RIP abort the job if
images below a certain minimum resolution are found. The resolution is calculated
after scaling (effective when placing the image, including a possible global RIP
scaling) and is a very solid quality check before a bad plate or film is made.
7.5 Native Input
When bitmap images are present in the job, they will only be contourized if the
output resolution is not equal (or is not a multiple of) the resolution of the bitmap
image or if the bitmap image is rotated over an angle that is not a multiple of 90
degrees. In case of correct expose resolution and no rotation the bitmap image will
be treated in an optimized way (direct access to the image for direct exposure).
Note
This is only for an EskoLink workflow, using Esko native file formats (PDF, PDFPLA,
PDFSTA,...).
Queue Settings
7.5.1 Screening
Note
For RIP flavors that produce unscreened output the screening options are not applicable.
7.5.2 Abort for images with scaled resolution below... dpi
Checking this toggle makes sure a resolution check on incoming images is
performed. This option offers you the possibility to get the RIP abort the job if
images below a certain minimum resolution are found. The resolution is calculated
after scaling (effective when placing the image, including a possible global RIP
scaling) and is a very solid quality check before a bad output plate or film is made.
7.6 PS/PDF marks
Queue Settings
This tab offers you the possibility to have register marks added to the FlexRip
output, when using the PostScript channel (AppleTalk, Hot Folder or Named Pipe).
It includes a layout mode option for color strips and data legend, options for what
should be shown and what shouldn't and an input field where you can enter your
own text. All this can be very important for quality control. E.g. the queue info can
be added to the RIP output which will allow you to quickly check if the correct
queue was used.
7.6.1 Layout mode
Select how you want your mark to appear: Horizontal, Thin Horizontal, Vertical,
Thin Vertical and None. Starting point is the top left corner.
The default setting is Horizontal.
The height of the standard mark is 13 mm, a thin mark is 6 mm.
Queue Settings
7.6.2 Include
7.6.2.1 Color strip
If you want to add a color strip to a film, plate or proof, specify what colors you

If you do not want to add a color strip, select (none).
7.6.2.2 Customer logo
Check the box if you want to add a customer logo to the proof.
Click the Browse button to open the 'Select a Customer logo file' dialog. Only .eps
files can be used as a logo.
Note
Logo marks should be eps files in CMYK or 1 color. An RGB logo will have disappeared
after ripping.
Warning
Take your logo mark into consideration when making plates for a one-color job. If your logo
contains 4 colors, 4 plates will be created instead of the expected one.

7.6.2.3 Data legend
Check the boxes to indicate which items you want to include in the data legend. Use

Note
There are no requirements concerning the text layout. Be aware that template variables do
not work for the data legend field.
7.7 Proofer settings
7.7.1 Configuration Set
Queue Settings
Before you can proof the job, select a proofer by clicking the dropdown menu under
'Configuration set'. A list of existing proofers will appear. Select the proofer you
prefer. If you have two proofer rips, you'll have a list of configurations per proofer
setup. If no proofers appear, you should first configure a proofer in the FlexProof
Setup application. Please consult the 'Proofer Setup' manual to see how to add,
change or delete proofer configurations.
Please refer to the FlexProof Setup manual for more information on how to create
proofer configurations.
Note
If you use the EskoLink queue, you can leave the configuration setting to 'none'. When
PS/PDF files are sent to the RIP, it is mandatory to select a configuration.
7.7.2 Output
Here you can decide whether to make a color proof, a grey proof or proof
separations. Four options can be selected. Two of them generate Composite output,
which means that the selected separations are recombined, either ‘Colored’ or in
‘Grayscale’.
The other two options generate ‘Separate’ output, which means that each selected
separation results in separate output, either in Black &amp; White, or Colored in its own
separation color.
Choose '(none)’ if you use the EskoLink queue.
In a PostScript workflow it is mandatory to select an output option from the list.
Composite
The composite option will combine all separations to a 'Colored' or 'Grayscale'
proof.
Colored
The 'Composite' 'Colored' option is used to proof all the separations on top
of each other in COLOR.
Grayscale
The 'Composite' 'Colored' option is used to proof all the separations on top
of each other in GRAY.
Queue Settings
Note
When printing to a Windows printer, &quot;grayscale&quot; can also be set in the driver. The
Image downloader will give feedback if &quot;grayscale&quot; is set in the driver options. It
can not be overruled.
Separate
The separate option will proof all separations listed in the 'Separations' box
sequentially in color or Black and White.
Black &amp; White
All separations you added to the job will be proofed sequentially in black.
Queue Settings
Note
When printing to a Windows printer, &quot;grayscale&quot; can also be set in the driver. The
Image downloader will give feedback if &quot;grayscale&quot; is set in the driver options. It
can not be overruled.
Colored
All separations you added to the job will be proofed sequentially in color.
7.7.3 Use &amp; Color management
Note
Please check the Color Engine Pilot manual for a more detailed description on the Esko Color
Management System. It contains elaborate information on how to measure profiles, make
color strategies or register ICC profiles.
Color Strategy:
Color strategies are a bundle of settings for Color Management. By default, there is 1
color strategy available, called 'linear', which leaves CMYK information untouched
and uses a default conversion for Special inks. Color Strategies can only be made
with Color Engine Pilot. Choose the color strategy that you always want to use with
this queue.
Note
Queue Settings
The color management options are available for 'colored' output only.
Warning
If a Proofer profile was filled out in the Setup of the FlexProof Image Downloader, you will
only see the color strategies that use the same profile.
Note
If a new profile or color strategy was made when the Image Downloader was already
started up, there is no need to restart. You can load new profiles and strategies by going to
the 'Resources' menu and clicking 'Refresh CMS Data List'.
Profile:
Choose Profile if you want to use 2 ICC or Esko profiles to do color management.
Source Profile:
The source profile describes what you want to simulate (e.g. a profile of your
flexo press). This process can be a registered ICC profile or a native Esko
profile. There are a number of default native Esko profiles on the system (e.g.
crom_offs which stands for Cromalin Offset). If you measured a native Esko
profile yourself (e.g. from your own Flexo press), you will be able to select it
here.
Proofer profile:
The destination profile describes the proofer. Select the proofer profile that
describes the colors of your proofer. (e.g. the characteristics of your Iris
proofer). Both native proofer profiles and ICC profiles of proofers are
available in this list. There are also defaults. (e.g. ddcw_glossy, a description
for a Digital Cromalin/WaterProof on glossy paper).
Rendering intent:
The rendering intent decides how you will visualize the simulated profile on
your proofer. Since there are many differences between the simulated
process (e.g. a gravure press) and the proofer, the CMS software gives some
options to give you the best result for your purpose. If you choose a native
Esko profile as a destination profile, you will have other options:
1.
Background: Use this option if you want to use background
simulation and an exact color match, including the paper simulation.
2.
No Background: Use this option if you don’t want to use
background simulation. The white point of the source will be
mapped on the white point of the destination process. This rendering
intent takes into account the ability of the human eye to adapt to the
surrounding white.
Both a rendering intent and black mapping have to be filled in. If you leave it
to 'none', the system will default to 'No background' and 'No black mapping'
Queue Settings
for Esko profiles and to 'Relative Colorimetric' for ICC profiles.
Black mapping:
This option is only available if you choose an Esko destination profile (not if
your destination profile is an ICC profile). Black will be mapped onto black
or, in other words, the black separation will only be printed in black ink. If
you have black text for example, it will only be printed in black. Switching
off this option means that your text will be made up out of 4 inks on the
proofer, which can cause some unwanted effect if the proofer is slightly out
of register. In case you want to simulate a very dark black, which is darker
than the black of your proofer, you might want to switch this option off. The
other inks will have to reach the dark black that you are trying to simulate.
Tip
ICC profiles can be imported with the &quot;Import ICC Profiles&quot; tool.
7.7.4 Fit on paper
It is possible to ask for the output to be downscaled to fit the imageable area of a
paper size as preset in a proofer configuration. If no real paper size was selected
in the proofer configuration, the ‘Fit on Paper’ option will be disabled.
Define the paper size via Start &gt; Programs &gt; Esko &gt; FlexRipProof 12 &gt; FlexProof
Setup.
When the option “Fit on paper” is set to 'Yes’, selecting a paper size in the FlexRip
Dispatcher will automatically scale the job up or down to the size of the printer.
When using the native channel it will also automatically rotate the job to make
optimal use of the paper (not for PS jobs).
7.8 Debugging
This tool enables you to control the content of the log files. You can make your log
files report basic info or you could have them report all kinds of details on the
complete RIP action.
Queue Settings
Why is this so interesting?
Extensive log files are very helpful when a problem occurs and you or our Customer
Service is looking for an explanation and solution to the problem. Our advice is to
always have extensive log files made. The actual log file can be consulted by doubleclicking the process number in History View (first column 'job') or can be opened in
WordPad or NotePad (standard text editors from Windows).
The log files (per Dispatcher) always reside in the Logging folder. Note that it is
possible that the output folder has another name that you specified while
configuring the FlexRip. The path listed below is the default path:
C:\Esko\bg_data_FlexRipproof_v120\LOGGING
To change a debug setting, select the debug option and enter the new value in the
input field. The minimum and maximum values are indicated.
Some advised settings:
•
•
Statistics: advised setting: 5
Extra profiling: advised setting: 1
Queue Settings
•
•
•
Expose Ticket (exptdebug): advised setting: 0
Statistics on error: advised setting: 3. This will provide more info when errors
occur.
Screening: advised setting: 0
Warning
The higher the value, the more chance the system generates huge log files.
In the History View (page 75) chapter, you will find some guidelines on how to read
log files and in the appendix there is a section that explains some classic errors (page
90).
Reset All: Will reset the debugging parameters to their default settings.
7.9 Copydot Tuning
7.9.1 Background
7.9.1.1 Performance &amp; Memory Management
Lineart Pixel images are contourized in the FlexRip. This is the best solution for
simple images (logos etc.) because, by contourizing, the images are handled as other
linework. Transforming, clipping, trapping or screening of those images is done the
same way linework is processed. This method however, gives problems for huge
images containing extremely fine detail like screens. In such cases, contourizing
needs a lot of memory, which slows down the FlexRip. To overcome this problem,
the FlexRip uses a copydot optimization.
7.9.1.2 Copydot workflow
Copydot images are bitmap images, representing pre-ripped or scanned pages.
These images are stored in a bitmap file format (TIFF, DCS, EPS, ..). Most of the time
we cannot see the difference with bitmap images representing logos or simple
drawings. This makes it rather difficult for the RIP to decide if the bitmap should be
contourized or not. In some cases, we can extract that information out of the job.
Copydots included in a DCS file are recognized as copydot. Copydots that are
manually placed in the job by means of an editor are not recognized as copydot and
by consequence, will be contourized.
7.9.1.3 Copydot and paint modes
A bitmap image can be set in 3 different modes:
1. ImageMask
Queue Settings
Paint is only applied to black areas. White points are not part of the image. They
always leave the background unaltered.
2. Image
Paint is applied to both black and white pixels.
3. Copydot
In paint mode masking, it behaves always as Image. For all other paint modes,
the copydot image is bitwise stored into the background.
By default a bitmap image is set to ‘ImageMask’. This means that when the paint
mode is masking (e.g. opaque ink mode in Esko PackEdge), the bitmap image will
always be contourized!
7.9.2 Queue Settings
To define or change the RIP copydot recognition, you must check the ‘Include
Tuning Options’ box in the ‘Input Queue Settings’ of the Dispatcher / Options
/ Program Options / Input Queue Settings / Copydot Tuning Options.
This will give you four extra tabs in the Dispatcher, one of which is the ‘Copydot
Tuning’ tab.
Queue Settings
Queue Settings
By default the ‘Automatic Copydot recognition’ is active.
The following 'rules' are used to treat an image as a copydot image:
•
•
A copydot image must be a solid object. A screened bitmap image is never
handled as copydot.
A copydot image has a rather ‘high resolution’ and is not ‘small’. A copydot
image must have at least 1000 rows or columns.
Queue Settings
7.9.2.1 Resample
When the RIP treats and image as a copydot image, the following happens:
1. With the size of the copydot image (inches, mm, .. ) and the requested output
resolution the number of resulting output pixels is calculated = X pixels.
2. The FlexRip checks the actual number of pixels that are in the copydot image
itself = Y pixels.
If the difference between X and Y is higher than the value defined (default 1), then
the copydot image will be re-sampled.
In case different copydots images in a job have slight differences in resolution, and
you want to keep that resolution, you should set the resample value a bit higher (ex.
10).
Note
However, if the copydot image is set in a masking mode, then the image wil again be
contourized.
7.9.2.2 Abort
If the difference between X and Y is higher than the value defined, the RIP will be
aborted. When set blank (also the default), the FlexRip will never be aborted.
7.9.2.3 Use Copydot preview
If you choose to use a copydot preview, set the following options.
•
•
Enter your preferred resolution in pixels per inch.
If there is no preview available, then specify how the RIP should behave:
• Abort.
• Revert to Copydot itself.
Status Monitor
8 Status Monitor
Start up the Status Monitor by selecting 'Status Monitor' from the Tools menu in the
Dispatcher that you want to monitor. The Status Monitor gives information on the
status of the current and past ripping processes.
8.1 General overview
In the Status Monitor three panes can be distinguished:
1. The upper pane presents all queues with their type and current status.
2. The middle pane displays info about the 3 RIP channels (2 Esko-native channels
and one PostScript channel).
3. Messages are shown in the lower pane of the monitor.
The Rip kernel sends two types of information: messages and info.
Info data supersedes the previous data, such as the actual page number the RIP is
processing. When ripping, the information &quot;page number&quot; starts with 1, becomes 2,
etc. When the RIP sends this kind of information, the Dispatcher knows that it can
replace the previous value of &quot;page number&quot; with a new value.
Status Monitor
Messages, however, are stored in a list by the Dispatcher. New messages are
constantly added to the list. That is why you will see entries like 'processing job'
when the job has long been processed already.
For each standard RIP process (or every time the RIP 'wakes up' after an internal
error), you will see these 4 different messages (as seen also in above graphic of the
Status Monitor window):
1. Identification (FRIP 12.0.0 + version date ). The software version number and
date of the Rip kernel.
2. Output identification (output module version number + version date). Shows the
type of output module.
3. Input data channel (IOSTREAM): Reading the input (PS).
4. Processing job (path): Actually ripping, exposing, making output. All following
jobs will only show the 'processing job' message.
8.2 Server menu
8.2.1 Connect to
This function allows the monitor to connect to a specific port number on a particular
computer running a Dispatcher application. By default the Status Monitor connects
to the Dispatcher that started up the application. If connection is to be established
with another Dispatcher, possibly on another system, enter the host name and port
number and click OK.
Status Monitor
8.2.2 Trace messages
Trace information is info created by the Dispatcher each time an important event
occurs (a job that is started…). It is used primarily for troubleshooting. Trace files
are created by the Dispatcher and viewed in the Status Monitor. They are stored in
the Logging folder.
Active: In the Dispatcher user interface it is possible to deactivate tracing. If tracing
is not active then the option &quot;Not Active&quot; will be shown. Always leave tracing
active. You will only need these trace files when Esko Customer Service asks you to
consult or send one.
Note
Trace files can be viewed in text editors. The files contain hexadecimal characters, but
WordPad has no problem showing them. You may, however, experience problems when
opening trace files in other editors.
Note
If it is not possible to open a trace file, take a copy of the file and open this copy in a text
editor.
History View
9 History View
The History View program keeps track of processed jobs and enables you to consult
their log files. The amount of messages in the History View is determined in the
Program Options (Dispatcher / Options menu). The list can be emptied by choosing
'Clear History' from the Dispatcher Rip menu, which also deletes the actual log files.
History View is a 'client' program of a Dispatcher. It will only show the history list
when it is connected to a Dispatcher. When you start up History View, it will
connect to the default port number of that Dispatcher (3031). In case you have
multiple Dispatchers in your FlexRip configuration, History View will want to
know to which Dispatcher it has to connect. Right-click the top window bar of the
History View and choose Connect.
'Save As…' in the Server menu will save the currently selected log file.
History View
Enter the correct Dispatcher port. The History View is now connected to that
specific Dispatcher and will only show its specific history. You can now start up
another History View and connect it to the other Dispatcher, etc...
History View
Double-clicking the processed Job Number (left column) opens a view window of
the log file that the RIP made of the entire processing of the PostScript file. The log
files (per Dispatcher) always reside in the Logging folder. Note that it is possible
that the output folder has another name that you specified while configuring the
FlexRip. The path listed below is the default path.
E.g.: C:\Esko\bg_data_FlexRipproof_v120\proof\LOGGING.
Note
Log files are text files so they can be viewed with standard Windows text editors like
NotePad and WordPad. These offer search functionality, which is convenient when looking
for specific info in these (possibly huge) log files.
History View
The appendix of this document contains a more detailed explanation of possible
errors that can be described in log files. The contents of the log file can be managed
with the debug options in the Queue settings (see the Debugging (page 65) chapter).
The next section will help you to read log files.
9.1 Log files: guidelines
When opening a log file, the local INI file is the first thing you see. But except for
that, the log file is also extended with the set of environment variables that were used
when ripping (those set up by the server, if any, and the ones specified in the
FlexRip Configurator), and an indication of the dispatcher queue that was used to
process the job. All this should make it easier for our Customer Service to determine
the problem and for you to supply the required info to our Customer Service.
•
What dot / LPI / angle did the RIP really take?
You will find this screening information by searching for these words:
'BG screen'
'Sampled Screen'
'lin'
In a PostScript workflow, the log file might first show some incorrect LPI
and angle information, depending on the application and your debug
settings (Typical are the offset settings of LPI 120 and angle 45). What you
see here is the search order that the RIP is following. It starts with the
default offset settings and then looks in the PostScript file to see what the
correct values are.
History View
The RIP will take the requested PostScript file screening settings and the log
file will show them. Use the following rule to check the correct dot, LPI and
angle settings: the last time the screen info is mentioned just before the
actual ripping starts ('start expose'). The screening settings shown there will
be used to create the output file.
•
When printing from Freehand, you can also search for 'Application' (and
the next line will contain the really used screen settings).
'Sample Screen'
The first appearance is e.g. the fake default LPI of 120, but just continue to
search. Usually, the third one already shows a change and you will see the
actual 'lin' (lineature/ruling) taken by the RIP.
•
Output folder: search for the word outdir'
•
Output name (name of the output file): search for the word 'output' (at least
in one of the expose ticket tables.)
•
Rip version: search for following words:
I_CTRL_FI Identification (e.g. FRIP 12.0.0)
I_CTRL_OI Output Identification (e.g. TIFF MONO 12 02 (month day
year))
The FRIP version is the version of the 'FlexRip kernel' (the base).
•
Font replacement: search for the words:
'Not found', using (then you will find):
I_OSTREAM_BB
Byte Buffer Dump
'fontname' not found, using Courier...
•
How many colors, separations, files were made?
'start expose': Shows the time indication of each new file that is written.
'Progressline': Shows the actual ripping moment + progress info per inch.
'I_CTRL_PN' and 'page number’: Shows the number of PostScript pages that
the RIP is looking for.
Every log file will show this error at the end:
W_CTRL Warning: 'No data in output'
W_CTRL Warning: endpage (FALSE), page discarded
This simply means that there are no more separations described in that job,
so immediately after this warning the RIP will end processing that file.
•
It is important to know that there can be 2 steps in the FlexProof workflow
(depending on the workflow chosen):
1. Ripping to separated, temporary files
2. Merging the separated files into 1 CMYK or RGB file The information
you will find in the log file on the first stage is very similar to what you
find when you expose to an ImageSetter for example. You will see the
scan lines for every separation.
History View
Example:
I_CTRL_PROGRESSLINE 300
I_CTRL_PROGRESSLINE 600
I_CTRL_PROGRESSLINE 900
I_CTRL_PROGRESSLINE 1200
I_CTRL_PROGRESSLINE 1500
I_CTRL_PROGRESSLINE 1800
I_CTRL_PROGRESSLINE 2100
I_CTRL_PROGRESSLINE 2400
I_CTRL_PROGRESSLINE 2700
I_CTRL_PROGRESSLINE 3000
I_CTRL_PROGRESSLINE 3300
I_CTRL_PROGRESSLINE 3600
The information on the second stage is also very important. This is where
Color Management is performed and where all separations are merged
together.
History View
•
What color strategy has been used?
Look for a line that says:
Loading color strategy …
Note
A color strategy “linear” is used by default. This color strategy does not do any
color
conversion. The cyan will only be printed with cyan. For special inks, Esko CMS is
used by default.
•
What happened to the output file?
1. When printing to a Windows printer the file will be submitted to the
printer.
2. When printing to file, the final output file is moved from a cold folder to
a final output folder.
Note
If you are working in an Automation Engine environment and use the Image
Downloader task to merge separations, the log file will end with “Ripping to
separated, temporary files”.
Workflow: flavors and hints
10 Workflow: flavors and hints
10.1 Who decides: the FlexRip or the
operator?
You will have noticed that there are several ways to work with the FlexRip (See the
Priority of Settings (page 43) chapter).
•
•
•
Some people want the FlexRip to decide settings and even overrule the ones
that the operator chose. This is often referred to as the 'fail-safe' method to
avoid mistakes from operators.
Some, however, do not want the FlexRip to take any decisions, but want it to
keep all the settings the operator set in the PostScript file, or in the ticket in
case of an Esko native workflow. This could be referred to as &quot;All Power to
the Operator&quot; method.
Settings that are not answered by the Dispatcher or ticket/PostScript file are
taken from the Queue Defaults.
The decision is completely up to the customer. The difference between these choices
is visualized by the use of the priority of RIP settings and the amount of Dispatcher
queues. If queues take hard decisions, then their names better reflect what they do.
10.2 What is best: AppleTalk or Hot
Folders?
As AppleTalk is no longer supported from Mac OS X 10.6 (Snow Leopard) onwards,
Hot Folders is the remaining choice.
10.3 What if you rip for more than one
output device?
If you have more than one output device that you want to send FlexRip output files
to, you need more than one Dispatcher. Each Dispatcher is configured to serve one
specific machine.
Esko Curve Pilot: Esko’s Dot Gain Compensation Tool
11 Esko Curve Pilot: Esko's Dot
Gain Compensation tool
This section merely serves as an introduction. For more detailed information we
refer to the Esko Curve Pilot documentation on your Suite 12 DVD.
11.1 Terminology
•
•
•
A DGC file stands for Dot Gain Compensation file. It is a curve.
A DGC Strategy (*.icpro) is a set of curves. One of the included curves will
be chosen depending on specific a screen ruling, dot, angle or ink
(separation).
A SCRDGC (Screen Based DGC) is a former set of curves. They can still be
used; however, Esko Curve Pilot 12 will not create SCRDGC’s anymore.
11.2 Basic explanation and general
workflow
The high dot gain of e.g. the flexo printing process results in the need for
compensation curves. With these curves, the imaged data are lighter, so the printed
result is closer to the intended densities.
Esko prefers compensation curves to be executed in the RIP, since a fully digital
workflow has many advantages:
•
•
•
All data are print-process independent (same image for offset and flexo
output).
Digital tools can be trusted and are 100 % repeatable.
Time gain.
A CtP (Computer to Plate) workflow will use different compensation curves than a
CtF (Computer to Film). All the physical 'problems' with films and the 'film to plate'
copy do no longer exist.
Example
The dot gain of digital flexo (CDI) approaches or even matches the Offset dot gain.
The main effect of the CtP workflow is the quality of the plate: dots are sharper (and
stronger). This also results in very specific compensation curves.
Another reason for using curves is because of the nature of the printing process, but
depends on your workflow.
Esko Curve Pilot: Esko’s Dot Gain Compensation Tool
If you work with 'independent' data (i.e. your data are not, or only slightly,
retouched for specific printing process reasons), then you will have to specify a
flexo/offset compensation curve that will take care of the dot gain of the flexo/offset
process. Again, this one may be general (DGC: one curve for all separations) or a
specific one (Strategy: set of DGC's per dot/lpi/angle). These press curves will not be
similar to curves that are used for conventional plates that were made through film
contact! (Difference is less apparent for offset processes).
You also have a tool called 'target'. In general, all curves can again be compensated
with a 'target'. Adding these curves to (inside) an existing curve means: &quot;Let's not
forget that at image scanning time and while looking at monitors, we were already
in an offset-Cromalin/WaterProof environment that was precompensated for offset&quot;.
You might have the approval this flexo job based on an analogue
Cromalin/WaterProof that shows offset dot-gain. If then you want the flexo print
result to look like that Cromalin/WaterProof, you should deduct that offset gain
from the one happening on the flexo press! That deduction is done by using that
target (or reference) curve inside your flexo press dgc. What is then left over is the
difference between flexo and offset dot gain.
Depending on the entire printing, the press compensation curves that are used to
adapt the output files for a device will vary.
Advanced DGC requirements such as color based DGC strategies, are best handled
in Esko Curve Pilot (optional).
How do you make your DGC and ICPRO files?
Here's a short overview:
1.
2.
3.
4.
5.
6.
Output test jobs (strips) without any compensation curves.
Print on press in typical conditions.
Measure results (percentages / densities).
Fill in data in Esko Curve Pilot.
Output test jobs again now with the compensation curves you made.
Print on press in typical conditions. The result should reflect the digital
construction of the job.
11.3 Where are my SCR(DGC) files and
ICPRO files?
Esko Curve Pilot can be installed on the FlexRip or Automation Engine, but it is also
possible to install it on other PCs.
If you have a server, all dgc files and Strategies will be located on the server. If you
Esko Curve Pilot: Esko’s Dot Gain Compensation Tool
do not, they are stored locally on the FlexRip.
Make sure that:
1. the editors know where to find and write the curves.
2. the RIP (=Dispatchers) know where to find them.
On a new, non-customized FlexRip, the dgc files and Strategies are standard on
C:\Esko\bg_data_dgc_v010
The target curve(s) are in a subfolder 'refdgc':
C:\Esko\bg_data_dgc_v010\refdgc
More information on how to install the Esko Curve Pilot, please refer to the Esko
Curve Pilot documentation on the Suite 12 DVD.
Tip
Always keep a backup copy of your curves, you do not want to loose all the work you put in
there. Even a floppy disk could contain all your curves.
11.4 Using old DGC files
If you have DGC files from a FastLane v9.4 system or even older, you can continue
using these DGC files on the FlexRip.
Best results are obtained after having loaded and saved the DGC files into Esko
Curve Pilot. This will improve the quality and smoothness of the curve. We refer to
the appendices in the Esko Curve Pilot manual on the Suite 12 DVD for more
elaborate information.
Data backup and customization
12 Data backup and
customization
A working FlexRip contains the standard FlexRip software that was configured to
the customer’s specific devices and workflow (Dispatcher Queues: their type,
amount, names and their settings). This configuration results in small files that are
very typical per customer. Configuration files are backed up by the FlexRip
Configurator. Please refer to the Configurator documentation for more information
on backing up configuration files.
The FlexRip contains output files. We see that some customers back up their output
files and some do not. This depends very much on other archiving methods in the
workflow. How you back up all these data is your decision. Your system manager
should advise the workflow responsible what devices and procedures are available
with this Windows2003 computer. You could copy data to another disk to avoid loss
in case of hard disk problems. You could share a part of the FlexRip hard disks and
copy the data to another computer that has a CD writer (or optical disks or...). Some
more advice though:
Back up your DGC data
Copy your DGC files to the backup folder you made on your data disk or copy them
all to an external disk. Do this regularly.
Warning
Never put a (any kind of) file that was on a CD or a DVD on an EskoFlexRip Hot Folder. A
file that comes from a CD or DVD-ROM is R.O.: Read Only! This means that after ripping
the file, the RIP will not be able to delete the file and will rip it over and over again until the
hard disk where your output folder is situated, is completely filled up.
Classic errors and their explanation
13 Classic errors and their
explanation
The History View program will show if a RIP action was completed successfully or
if it encountered an error. Error Info usually concerns 'Internal Errors' or 'PostScript
Errors'. As said before, a warning in a FlexRip log file is not always an error, but still
it will appear in the log file.
For instance, in some log files, you will see the following warning a number of
times:
W_DATA
Warning: Output resolution not integer...
This is completely normal. Since the effective PPI has to be an 'integer' number,
the RIP will change your resolution in background just a little bit, e.g. from
2104.9 to 2105 ppi.
Another warning that appears in every log file (at the end) is
W_CTRL
Warning: No data in output!
W_CTRL
Warning: endpage(FALSE), page discarded
I_TCTGEN_INFO
no Contone data Processed.
This all means that the PostScript Interpreter is looking for the next color ('page')
but does not find any. It indicates that there are no more separations described in
the PostScript file and that all pages (=inks =separations) have been ripped.
You should in fact only be alarmed if you do not see the word 'Success' in the
Status column of the History View.
•
•
PostScript errors are encountered by the FlexRip's PostScript Interpreter.
This could be e.g. because the PostScript file is not complete, because it
contains inappropriate PostScript commands for the FlexRip (&quot;dirty
PostScript&quot;), or because the FlexRip does not understand the commands.
Internal errors have to do with the general working of the FlexRip or with
the status of the RIP itself. If someone, during a RIP action, closes the
Dispatcher or chooses the 'Abort job' function, you are bound to get this kind
of error. You will also get an internal error if the RIP is asked to do things it
cannot do. An example: the PostScript file might be read without problems,
but it asks the RIP to execute a DGC curve that does not exist or to output
the e.g. LEN or TIFF file to a folder that was deleted. Both of these operator
mistakes will cause internal errors.
Warning
Double-clicking the job number in the History View will show you the log file in an internal
window. You may find it much more practical to read large log files when you open them in
a simple standard text editor (with a search function!) that Windows offers like 'NotePad' or
'WordPad'.
Classic errors and their explanation
What follows is a list of some typical errors and the way they are described in the
log file. An error is always first described with a code, followed by some more or
less 'readable' explanation.
Example
Example of such a code: 'E_DGCNAM_IE':
E
= Error (I = Info; W = Warning)
DGCNAM
= something wrong with the name of the dgc file
IE
= It is an Internal Error
These codes are very valuable for our Customer Service, so do mention them too
when reporting problems.
13.1 Classic PostScript errors
13.1.1 Examples
•
General warning
E_CONTROL_PE PostScript error occurred (parser warning: PS error happened)
This is a standard line for most PostScript errors, and will be preceded or
followed by a more specific message.
•
Rip was stopped during reading of the PostScript file
W_CTRL Warning: FastRip cancelled
This indicates that something interrupted the RIP. It was suddenly stopped
and the PostScript file could not be read anymore.
To check: Did someone choose 'Abort Job' from the Dispatcher's Server
menu? Did someone close the Dispatcher program or even shut down the
FlexRip?
See to it that the RIP is started and just try to send the job again. It is possible
that you do not have to restart the Dispatcher, because the RIP normally restarts automatically when any Queue or Hot Folder receives a new
PostScript file.
•
'Illegal' dot types in PostScript
If you input from ArtPro, you might find following error in the log file and
similar 'Error Info' in the History View:
I_OSTREAM_PEMSG %%[Error: rangecheck: Offending Command: set
halftone;ErrorInfo: Halftonetype 95 ]%%
In ArtPro it is possible to select a non-standard dot (in the 'Separations'
menu). These dot types for a Nexus RIP should not be allowed in PostScript
code that is not made for such a RIP. Please see the Printing documentation
(chapter 'Remark on printing from ArtPro).
Solution: Overruling the dot in the Dispatcher's Queue settings does not
Classic errors and their explanation
help. As said before, the job has to be printed again from ArtPro and a
standard PostScript dot (top part of list) or no dot has to be selected in the
menu 'separations'. Then the PostScript file will be fully readable and the
RIP will continue to see what Esko dot has to be used in the end.
Using ScreenFilter is another option. If multiple dots are defined in ArtPro
you will need the ScreenFilter to handle these jobs. ScreenFilter will capture
the screening info and will allow you to define swap tables for incoming
screens.
For more information, please refer to the ScreenFilter documentation on the
Suite 12 DVD. There's even a third solution to overcome this problem. You
can rewrite the PostScript file in ArtPro using PS screening instead of Nexus
screening. The PS screening of ArtPro will work if you switch to &quot;PostScript
screening&quot; in the FlexRip Dispatcher. All dots as described in the PS file will
then be correctly output.
•
Ink name descriptions
W_CLASS
Warning: Multiple invocations of PLATECOLOR on this Page
Meaning: Output file names always get a suffix based on the ink name
description in the PostScript file. This official description of the separation
name is the command ‘PlateColor’. If the RIP finds (in 1 page, so within the
same separation) multiple descriptions of this ink, it will give this warning.
The warning indicates that this behavior is not standard, but does not have
to be a problem.
•
Font not available
When a font is not included in the PostScript file, and not available in the
RIP itself, the following error messages will be displayed:
I_OSTREAM_BB Byte Buffer Dump (length: 46 bytes)
TextileRegular not found, using FontNotFound..
I_OSTREAM_BB Byte Buffer Dump (length: 55 bytes)
%%[ Error: invalidfont; OffendingCommand: findfont ]%%.
I_CONTROL_INFO Parser info: %%[ Error: invalidfont; OffendingCommand:
findfont ]%% I_OSTREAM_BB Byte Buffer Dump (length: 63 bytes)
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%.
I_CONTROL_INFO Parser info: %%[ Flushing: rest of job (to end-of-file) will be
ignored ]%%
E_CONTROL_PE PostScript error occurred (Parser warning: PS error happened)
13.1.2 Problem solving: 'capture' the PS file
If there is some mysterious problem with reading a PostScript file, and all other
obvious rules have been checked, then our Customer Service may ask you to
provide us the 'Captured PostScript file'. This is a text file that includes the
PostScript file itself plus a lot of other relevant data. So a 'captured PostScript file' is
not just the PostScript file that was intercepted, it is more than that.
Classic errors and their explanation
How to 'capture' a problem file?
1. Try to reproduce the problem with a small PS file (less data? only one
separation?)
2. Wait until all Dispatcher queues are in idle status.
3. Enable the 'Capture PostScript file' in the Program Options of the Options
menu in the Dispatcher and confirm with OK.
4. Have the problematic Postscript file ripped again and wait until the error
shows up again. This time the PostScript file was also 'captured' in a temp
folder.
5. The captured Postscript file will be called ps_trace_1.txt and can be found in
the Tmp folder. Note that it is possible that the output folder has another
name that you specified while configuring the FlexRip. The path listed below
is the default path.
C:\Esko\bg_data_FlexRipproof_v120\proof\tmp
Now deliver this .txt file to our Customer Service.
6. Do not forget to switch off the 'capturing' afterwards! So disable the 'Capture
PostScript file' in the Program Options of the Options menu in the
Dispatcher and confirm with OK.
13.2 Classic internal errors
•
Screen not found
E_SCRSEL_IE Internal error (Screen file xxx not found...)
Meaning: The screen file (.isb or .csb file) you requested was not found. A
screen file is an area of dots of 1 type, 1 angle, 1 size (lpi) and 1 resolution
(ppi).
Example
the screen file f8205c.isb represents:
f:
82:
05:
c:
flexo angles
angle 82
number of resolution set of that type
circular dot
Check if that dot is available on your FlexRip. If it is not purchased, it will
not
be in the central folder for the ‘screen files’:
C:\Esko\bg_data_screens_v010
Is the angle you requested a flexo angle? If not, the RIP will look for an
Offset
screen file and those have a name starting with an 'o'.
•
(Scr)dgc files not found
Classic errors and their explanation
E_SCRSEL_IE indicates that the RIP has trouble reading the DGC file.
This means that the FlexRip is not able to read the (scr)dgc file specified,
because:
•
the share could not be reached.
•
the file is not present.
•
the file is corrupt.
Perform the necessary checks to verify if the DGC file is present and opens
correctly.
•
Problems with writing the actual output file
E_CB_IE
Cannot create output file(s) ...
E_CTRL_CCF Cannot create file (fripout(5): E_openfile)
Meaning: The RIP would like to, but just cannot create a plate file or the
original output file. The output directory will be created when necessary.
Check the Queue settings to see where the RIP wants to write that output
file.
Classic errors and their explanation
Or in case of:
E_DEVCOM Output Device communication Error
Check if the hard disk (the one where the output folder is) still has space left
to write the output file? The hard disk may be filling up. If so, clean up and
delete some files or re-direct the output to a folder on another disk.
General troubleshooting
14 General troubleshooting
14.1 Queue settings 'disappear'
My Dispatcher Queue Settings seem to disappear…
Although this is not known as a bug in the FlexRip software, we would like to
comment on that. If you notice that queue settings get 'lost', then this is not a
problem in the FlexRip software itself, but in what surrounds this software. So
please look for the problem in the ‘environment’.
When you click OK after checking or changing Dispatcher Queue Settings, a
small .usr file is adapted. This .usr file (as all your specific settings of your
Dispatcher) is in: C:\Esko\bg_data_FlexRipproof_v120\proof\Data
The date and time of these files indicate when the Queue settings have been
changed. When that C drive is full, the RIP will have problems accessing and
writing those .usr files. So do check if your system drive is full and certainly why it
was full. Make sure that all your Hot Folders (large incoming PostScript files) or
output folders (where the CT files are written) are on your Data drive. Also check
whether or not your Hot Folders (Queue Info) delete the PostScript data after
ripping. Make sure that they do.
14.2 My input queue shows a 'fail' status
The AppleTalk queue is not automatically put in the 'idle' status.
If an item is not working because certain elements are not installed, the Dispatcher
will go into a “fail” status.
In this case the AppleTalk services are not running. Activate the AppleTalk services
and open the Dispatcher again.
General troubleshooting
14.3 The system disk is filling up
Why is my C drive so full?
If your C drive is filling up and you have no idea why, then check the contents of
the Tmp subdirectory of the data tree of the FlexRip flavor. If you see files with
strange names like 'stream_cdlclass57628_6234' (always begins with
stream_cdlclass, then one or two numbers and no extension), then these may be
remains of a PDF file that has not been ripped successfully. Before ripping a PDF
file, it is first converted to PostScript. The temporary PostScript files that are
generated are stored in the bg_tmp directory and will be deleted after ripping.
However, if the RIP ends with an internal error during ripping (crash, read only
PDF file from a CD…), it will stop but it will NOT delete these temporary files. In
this case, you'd better delete them yourself. Keep at least one to show at Esko
Customer Service.
14.4 FlexRip rips my file over and over again
I can't stop the RIP from ripping a certain job over and over again.
This is what happens when you have put a read-only file on a Hot Folder. The RIP
will try to delete it after the ripping but it can't, since this requires writing
permission. Solve this by stopping the Dispatcher (so 'abort job' is not enough!),
deleting the read-only file, and deleting all the unnecessary output files it created.
Restart the Dispatcher.
General troubleshooting
14.5 No output was generated from a PS file
There are several possibilities:
1. The job contains unregistered Designer inks.
Unregistered designer inks are inks like “Special red” that have no relation
with any real inks. These inks are often used in DTP. If you write a
Separated PS file from a job that contains such an ink, some applications
write no information on the kind of color it in the PS file. This is kind of
normal since Separated PS files are usually made for film output. This is why
FlexRip/Proof cannot reconstruct the color in the job. FlexRip/Proof will not
proof the design because there is no real information on the ink.
There are a couple of workarounds to this problem:
1.
Register the ink your Designer ink book on the FlexRip, using
Color Engine Pilot. You can just copy a PANTONE ink in the
Designer book and rename it to exactly the same name as the name in
your job.
2.
Use a PANTONE ink instead of the designer ink.
3.
Convert the special ink to CMYK when writing the PS file. If
that 'Special Red' is not present in the Esko ink database the whole
job will not be proofed! Look in the log file if that is the case.
Example
You will see something like: 'Error: The designer color rood4 is not available in the
CMS database and there is no color simulation available Processing of the job will be
stopped.' It depends on whether or not the application writes a CMYK equivalent
for that Designer ink in PS file.
Note that Esko PackEdge and Illustrator do not generate color information in
SEPARATED PS files.
2. Configuration was not filled in.
Please check if the proofer configuration (done in the FlexProof Setup) is
filled in the Dispatcher.
Warning
Remember that for all PS queues (Appletalk Hot Folder, Named Pipe), a
configuration has to be filled in!
General troubleshooting
14.6
I changed something in the CMS
database but the RIP does not take it
Every time you change something in the CMS database the Dispatcher has to be
restarted.
Example
if you have just measured a new Esko profile and you made new color strategy, then this
new color strategy can only be applied after the Dispatcher has been restarted. The same is
true when a new designer ink has been added to the database. The Dispatcher has to be
restarted before this ink will be recognized.
Tip
If you run into this problem sending PS files to a Hot Folder, a named pipe or an
AppleTalk queue, clicking “Abort Job” in the Server menu of the Dispatcher. “Abort Job”
re-initializes CMS.
General troubleshooting
14.7
In the log file, I get “access violation
while writing”
Example
Processing block 1
E_?_IE Internal error (exception: access violation while writing)
If you get this error, there is probably not enough space on the disk where the final output
file is written.
1. Check where the file is written. You can find this in the Setup of the “Image
Downloader”.
2. Check if there is enough space on that disk.
3. Clean up the disk.
4. Try to find out why the disk was filling up and try to solve it so the error
does not occur again.
14.8 In the log file, I get “Internal error
(Parser error: BG font not found)”
Example
E_CONTROL_IE Internal error (Parser error: BG font not found: 1204)
An Esko font in your job could not be found.
14.9
In the log file, I get “Internal error
(Could not allocate license &quot;frippdf&quot;)
There is a license problem. Maybe you are running two FlexRips on the same box
and you only have 1 FRIPPDF license. Make sure you have enough FRIPPDF
licenses.
14.10 The designer ink &quot;fond&quot; can not be
found in the CMS database
See the first item in No output was generated from a PS file (page 95).
General troubleshooting
14.11 Cannot find external image
An external image (a CT, an LP,..) cannot be found. Make sure all the external
images are present.
Tip
In case you are working with Esko native files, you can switch on the 'Foreign' button so
that all external images are searched on the local directory.
Frequently Asked Questions
15 Frequently Asked Questions
15.1 FlexRip software version
What version of FlexRip software do I have?
The software version can be found in every log file. You'll first see the ini file, then
the environment variables en below that, the software version will be mentioned.
15.2 Extra software on the FlexRip
Can I install some extra software on my FlexRip?
No, unless approved by Esko. Whenever you add, remove or reconfigure of
software on your FlexRip should be requested and reported to Esko Customer
Service. In general, upgrading any of the software that is already installed
(Windows, modem software, DiskShare) has to be reported and requested.
Installing additional new software will probably be forbidden. Any request will be
considered though. Send this request to the Customer Service department.
15.3 Screensaver
Can I use a screensaver on my FlexRip?
No! Even screensavers use CPU activity and all CPU on a FlexRip should be
dedicated the RIP itself. When a FlexRip is well configured, it should be quietly
doing its RIP work all day. Nobody should change any Queue settings or monitor or
read log files. This means it would even be logical to switch the monitor off.
15.4 Windows version
What version of Windows do I have?
In Explorer, choose 'About Windows' from the 'Help' menu and you will get an
exact description of your version of Windows on the second line.
Frequently Asked Questions
15.5 Rebooting the FlexRip
Should I reboot the FlexRip occasionally?
Yes. We have experienced that this WindowsNT-driven computer likes a 'shower'
every week. It will free up some hanging memory and therefore be a little faster
afterwards. Please do this occasionally, even when you would not even notice any
loss of speed.
15.6 FlexRip's computer name
What is the name of my FlexRip?
If in doubt: open a command prompt window (Start / Programs / Command
Prompt) and type: set computername. This will show the actual computer name and
more network information. This name is set by Esko. Do not change it. When still
desired, contact Esko first.
15.7 Info on the network address
Frequently Asked Questions
TCP/IP info:
If in doubt: open a command prompt window (Start / Programs / Command
Prompt) and type ipconfig/all. This will list all necessary info on the TCP/IP
configuration of this machine.

Appendix
9. Change the properties for that share. By default “Read only” is activated.
16.1.2 How to share FlexRip volumes for a PC (Microsoft
Windows 2000 Server)
Before being able to share, two conditions have to be met:
1. The FlexRip folder has to be 'shared' open enough for the user who wants to
access it (so there are no problems with file permissions).
2. The user on the DTP PC has to be known on the FlexRip or has to be able to
log in as user 'Guest'.
Therefore:
•
On the FlexRip: share the volume and open its permissions:
1. Right click the folder that you want to be visible for other PC's.
2. Choose 'Share this folder...'.
3. Activate 'Shared as:' and keep the proposed name (e.g. 'Hot Folders').
4. Keep the user limit to 'Maximum Allowed'.
5. Click 'Permissions': Set 'Full Control' for 'Everyone'.
6. Click OK and click OK again in the 'Folder properties' window.
Appendix
•
On the FlexRip: enable the account of user 'Guest':
1. Start / Programs / Administrative tools - Computer Management.
2. You will see 3 users: Administrator / Guest / Iusr_nameofrip
3. Double click the user 'Guest' to open its window 'Guest properties'.
4. De-activate 'account is disabled' (= so do enable this account).
5. Click OK.
6. Close the Computer Management dialog (top-right X). No restart is
needed.
16.1.3 How to share FlexRip volumes for a Macintosh or a
PC (Microsoft Windows 2000)
Note
Following will not be possible when your FlexRip does not have the required version of
Windows: Microsoft Windows2000 Server.
Note
Folders can be shared for Microsoft Windows AND Apple Macintosh at the same time.
Therefore, the procedure for both will be explained together.
The FlexRip folder has to be 'shared' open enough for the user who wants to access
it (so there are no problems with file permissions). The user on the DTP PC or Mac
has to be known on the FlexRip or has to be able to log in as user 'Guest'.
Therefore:
1. Log on a user ‘Administrator’.
2. Start / Programs / Administrative Tools (Common) / Computer
Management.
3. Have the right computer selected (&quot;local&quot; or name of your FlexRip). If not
visible, try to select the exact domain or ask your network manager for more
information.
4. System Tools / Shared Folders / Shares. You will see that a default volume is
already mounted (C:\Microsoft UAM volume).
5. Select &quot;Shares&quot;.
6. Choose Action / New File Share. Enable &quot;Microsoft Windows&quot; if you want a
Windows share, enable &quot;Apple Macintosh&quot; if you want a Macintosh share.
Enable both if you want a Windows AND Macintosh share.
Set the following options:
Computer: name of the FlexRip
Folder to Share: enter the correct Hot Folder path
Share Name: Windows Share Name
Share description: brief description of the share (optional)
Macintosh share name: The volume name is what will pop up in the Macintosh
Chooser application and will then be set visible on the Macintosh Desktop.
Appendix
7. Click &quot;Next&quot;.
8. Enable &quot;All users have full control&quot;.
9. Click &quot;Finish&quot;.
Note
Above procedures use the standard 'Services for Macintosh' that Windows2000
offers. Customers who would like to improve the file transfer speed between
Macintoshes and the FlexRip (Windows2000), could consider having this
connection via a software product of CYAN Software GmbH called 'MacServerIP'.
We successfully tested this in an EskoFlexRip workflow and have noticed filetransfer speeds of average 3 times faster (compared to the standard Windows
services). As this is only advice, we refer for all further info (and responsibility) to
this company's web site: www.cyansoftware.com.
16.1.4 How to mount FlexRip volumes on a PC (Microsoft
Windows 2000)
Mounting FlexRip Volumes on a PC will be done by simple 'mapping of network
drives'. We will explain this with an example.
The DTP PC will map a drive 'X' to represent the folder 'Hot Folders' on the FlexRip.
This way, the PC operator can easily print-save the PostScript files directly on the
Hot Folders.
On the DTP PC: map a network drive to the shared FlexRip folder.
1. Start / Programs / Accessories / Windows Explorer.
2. In Explorer: Tools / Map network drive.
3. Choose a free drive and type the correct path to the FlexRip folder:
E.g. X:\\fripnt01\hotfolders
Activate 'reconnect at logon'.
4. Click OK.
5. The mapped drive should now appear in the Windows Explorer. Should you
experience problems, ask your (Windows) system manager to do this for
you.
Note
Mapping a network drive will not ask you for a password because you enabled the guest
account on the FlexRip. If you write a PostScript file on an EskoFlexRip's Hot Folder, the
PostScript file will initially have owner 'Guest', but after being ripped the resulting output
file will have owner 'Administrator' (like it should be).

16.2 Merging
It is not possible to merge files on the FlexRip. Merging can be done via the ticket in
Automation Engine or the FlexRip Pilot.
For more information on merging, we refer to the Automation Engine
documentation.
16.3 What about OPI?
A FlexRip is by no means an OPI server itself (so not a 'provider'): a FlexRip should
therefore always receive 'fat' PostScript data. These data may have passed an OPI
server (where the missing or low-resolution images were replaced with highresolution images). In that case, the DTP operator prints to the OPI server, which
(after doing its OPI replacements) transfers (spools) the now 'fat' PostScript further
on to a specific, print queue on to the FlexRip.
Note
Automatic replacement of low-resolution images by high-resolution images of course
enhances the workflow. If you like OPI to be done before the PostScript data go to the
FlexRip, you may do this. But as OPI links are not mentioned in the product specification of
an EskoFlexRip, Esko is not the responsible for its connectivity. All info on how to connect
the OPI server's output channel to the FlexRip's input channels should be available to Esko
via the FlexRip pre-installation question list. The setup of this OPI workflow can then be
established during the initial installation training by the Esko instructor, this only by
joining forces between the 2 parties: the FlexRip instructor and the customer's in-house
specialist in that OPI software.

D
DynaCell screens
Esko DynaCell screens don’t have the limitation of a
limited set of available rulings and angles. This is
reached through on-the-fly calculation of the screening
pattern. The screens are calculated during the RIP
process based on the precise ruling, angle and dot
shape definition. Since this process happens in the RIP
black box just before exposure, the result of this
calculation has never been watched or optimized by
an Esko engineer. As a result, these screens have a
lower quality than the pre-calculated screens.
E
Esko Classic (precalculated) screens
Pre-calculated means that the aspect,
the form, the rulings and the angles of the screen are
pre-defined in the Esko screening labs. These screens
are the result of advanced engineering work. The
screens are optimized for a smooth aspect, good
behavior on the different printing processes, lack of
artifacts etc. Furthermore, the screens are designed
following a system of screen angles that avoids moir&eacute;
between the main colors (cyan, magenta and black).
The use of pre-calculated screens allows supporting
advanced screening features like stochastic screening
(Monet Screens) and transitional screening (SambaFlex
Screens). Pre-calculated screens have only one
disadvantage: since these screens have been designed
and tested one by one, there is only a limited number
of precalculated screens. Although the total number
exceeds 2000 different screen ruling/angle/dot shape
Glossary
combinations, it is very well possible that no
precalculated screen is close enough to a customer's
wish. This happens specifically when other angles
than flexo or offset angles are demanded. Esko precalculated screens with conventional screen patterns
are called Esko Classic screens.
F
Flate
The lossless deflate compression algorithm is based on two other
compression algorithms: Huffman encoding and LZ77
compression. Deflate is a smart algorithm that adapts
the way it compresses data to the actual data
themselves.
J
JPEG This file format for color-rich images was developed by the Joint
Photographic Experts Group committee. JPEG
compresses graphics of photographic color depth
better than competing file formats like GIF, and it
retains a high degree of color fidelity. This makes
JPEG files smaller. You can choose how much to
compress a JPEG file, but since it is a lossy format, the
smaller you compress the file, the more color
information will be lost.
 JPEG limited compression: very acceptable data
loss
 JPEG low compression: very acceptable loss of
data
 JPEG standard low compression:
 JPEG standard compression
 JPEG standard high compression
 JPEG high compression
 JPEG extreme compression: heavy compression,
lots of data is lost.
L
LEN
A LEN file is a bitmap file that is made by a FlexRip/C. 'LEN' stands for 'run
Length ENcoding', which is a way of encoding
bitmap files. The only information in this kind of file is
where to put dots and where not. The Grapholas
Glossary
software will then expose these dots on the printing
plate on the CDI drum.
The LEN file itself can not &quot;remember&quot; any ink
information of the separation. That's why the user will
have to specify which ink the LEN file is representing
(unless he wants a Black &amp; White proof of course).
LEN files have high resolutions as 2100 ppi and more.
Proofing on an HP proofer is typically done at a lower
resolution like 600ppi.
LZW
Compresses data using the LZW (Lempel-Ziv-Welch) adaptive compression
method, optionally after pretransformation by a
predictor function. This is a good general-purpose
encoding that is especially well suited for naturallanguage and PostScript-language text, but it is also
useful for image data.
P
PostScript screening
Using PostScript screening implies that all the
information needed to build up the dots has to be in
the PostScript file. There is no such thing as a
combination of PostScript and Esko screening! In
every DTP application, you can choose the LPI from
the Esko PPD or you can overrule it. Also the print
angle will be offered by the PPD but the DTP
applications permit you to enter other angles. If you
send these data to the RIP, the 'Esko screening' setting
will again change these values via its own 'jump-to'
mechanism. This means that the RIP will
automatically jump to the nearest LPI or angle that is
supported. If you do not use 'Esko screening' but
'PostScript screening', these 'special requests' will
indeed be realized by the FlexRip.
If you activate PostScript screening, the dot shape
should also be described in the PostScript file. If you
cannot select dot shapes in your DTP application, then
it will probably describe the standard Fogra Round
dot shape (see also Esko's Fogra Round).
Precalculated screens (Esko Classic) See Esko Classic (precalculated) screens.
R
RLE
RLE stands for Run Length Encoding. It is a lossless algorithm that only
offers decent compression ratios in specific types of
Glossary
data.
RLE is one of the easiest compression algorithms there is. It replaces
sequences of the same data values within a file by a
count number and a single value.
RLE compression can be used in the following file
formats:* TIFF files and * PDF files.
