General introduction
2 General introduction
This document is the user and training manual of a FlexRip/T4 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 Esko Suite
12 DVD that contains the following:
1. Software
2. User documentation on:
•
FlexRip/DCS (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 a 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.
12
Introduction to a FlexRip workflow
1. Input channels:
•
•
PostScript 3 / PDF 1.4 / PDF 1.5 / PDF 1.6
Normalized PDF (Esko’s native file formats)
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/Proof 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/DCS?
The FlexRip/DCS outputs DCS files that contain screened or unscreened data,
depending on the flavor.
•
•
The Screened flavor provides an interface for all workflows to a CtF
(computer to film) or offset CtP (computer to plate) device.
The Unscreened flavor is used for interfacing between a DTP application
and a proofing device.
FlexRip/DCS Unscreened can be used as an alternative to Esko FlexProof/TIFF to
output on the proofer device (e.g. a Dupont Digital Cromalin/WaterProof) if
Cromanet color management (Dupont) is to be used. In some cases it is also
accepted by gravure systems and can therefore be an alternative to FlexRip/TG.
FlexRip/DCS Screened can be used for dot proofing to devices. This can be
particularly interesting when the proofer is a CMYKOG(orange, green) proofer.

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 chapter (page 85) for a short introduction and the
dedicated Esko Curve Pilot documentation on the Esko Suite 12 DVD for an
in-depth 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.
14
Introduction to a FlexRip workflow
The output files will be written in a folder on the FlexRip PC.
See the flavor-specific workflows for more in-depth information.
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 form 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
15
Introduction to a FlexRip workflow
In a PostScript workflow, Esko strongly recommends using separated PostScript as
standard and preferred input channel.
Difference between composite and separate PostScript
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/DCS workflow Esko-native data or separated PostScript files from the
DTP station are sent to a specific FlexRip queue. The FlexRip/DCS will immediately
rip that file into DCS file(s).
Note
Taking in DCS files may be an option on your expose device (if any). Please check
with the vendor of the output device.
1. Screened workflow overview
This workflow can be used for film or plate output as well as for screened proofing
if foreign color management is needed and if the foreign system can do Pantone
simulation.
1. Every separation is ripped individually to a screened bitmap EPS.
2. When the last separation has been ripped, a master DCS file is written
(single or multiple file DCS).
3. All screening and dot gain curves are applied.
4. The DCS file is sent to a third party RIP that outputs to a proofer device.
16
Introduction to a FlexRip workflow
Note
Please pay attention that when the DCS file is to be used on a Mac (OS9) the file
name (including the extension, with dot) cannot contain more than 31 characters.
On Mac OSX this restriction is lifted and the file name can contain up to 255
characters.

Introduction to a FlexRip workflow
2. Unscreened workflow overview
1. Every separation is ripped individually to a grayscale EPS.
2. When the last separation has been ripped, a master DCS file is written (the
operator has the choice between a single file and a multiple file DCS).
3. No screening is applied.
4. The DCS file is sent to a third party RIP that outputs to a proofer device.
3.5 Output file type
DCS is the abbreviation for Desktop Color Separation and is in fact an EPS file that
contains some extra commentary lines. The EPS file points to plate files that are
either external files or are embedded in the file itself. The plate files are also EPS
files. This means that for each separation made by the RIP there will be a plate file,
compressed or uncompressed, in the resulting DCS file. External files do not have
the classic .eps extension but a short ink name of the ink they represent. E.g. the
plate file that represents the cyan ink will have the extension “.C”. For Pantones the
extension will be the Pantone number or short name of the
Pantone ink. For designers the extension begins with a D and is followed by the
designer ink name.
A DCS file may also include two previews (one for placement only and one for low
resolution proofing purposes from f.i. a DTP application).
The size of the DCS file is of course determined by the size of the job and the detail
it should describe the job separation with (ppi). A DCS file can be compressed or
uncompressed. If it is compressed it will be decompressed when opened in a
viewer. View programs only show you all the pixels when you zoom in enough. A
full view will not show all the pixels (it would make the viewer too slow), but will
sub-sample and give you a good general view.
Compression methods
Standard compression methods include CCITT G4 (Screened only), LZW and Flate.
FlexRip/DCS supports all of them.
•
•
CCITT G4: CCITT stands for “Comit&eacute; Consultative Internationale
Telefonique et Telegraphique” (International Telegraph and Telephone
Consultative Committee). The committee has defined many important
standards for data communications. G3 and G4 are two standards designed
for text. G3 is a faster compression algorithm whereas G4 has a higher
compression rate (smaller files).
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 natural-language and PostScript-language text, but it is also useful
for image data.
19
Introduction to a FlexRip workflow
•
Flate Compression: 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.
This is what a DCS file looks like (a full view of a magenta separation):

Introduction to a FlexRip workflow
These are 3 different zoom-ins, gradually showing the actual print dots:
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 DCS file according to its specific
settings.
21
Startup and shutdown of 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:
22
Startup and shutdown of FlexRip
”Begin logon”
'Press Ctrl + Alt + Delete to log on'
If you wish to use the normal FlexRip software, log on as user ‘FlexRip’ with
password 'flexrip'.
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.
•
•
•
Start up the &quot;Dispatcher” by double-clicking its desktop icon or by choosing
the right Dispatcher via Start ⇒All Programs ⇒Esko ⇒FlexRipDCS 12.0
Start up the 'Status Monitor' in the Tools menu in (each) Dispatcher.
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.
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)
23
Startup and shutdown of FlexRip
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
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.
24
An overview of programs on the FlexRip
5 An overview of programs on
the
FlexRip
5.1 General
Logged on as user ‘FlexRip’ (see next section for details on logon users (page 26)),
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 12.0. 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) and
DGC curves (single curves) will reside on the FlexRip or the Automation
Engine server.
25
An overview of programs on the FlexRip
Note
Esko Curve Pilot is further explained in a dedicated Esko Curve Pilot
document that can be found on your Esko Software Suite12 DVD.
Note
Curves for the CDI or 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 27), Status Monitor (page 72) and
History View (page 75) in detail.
26
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 ⇒FlexRipDCS 12.0 ⇒FlexRipDCS 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.
27
Dispatcher
6.2 Rip menu
The Server menu contains the following items:
1.
2.
3.
4.
5.
Clear History (page 28)
Send Job(s) (page 28)
Abort Job (page 29)
Restart PS Rip (page 29)
Exit (page 29)
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.
Note
28
Dispatcher
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.
29
Dispatcher
6.2.5 Exit
This will stop the Dispatcher program (and the RIP). Clicking the close button of the
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 30)
Queue Defaults (page 32)
Performance (page 33)
Rip Priority (page 33)
6.3.1 Program options
The program options are general Dispatcher settings. They can be set per
Dispatcher.
30
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_flexripdcs_v120\dcs\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.
31
Dispatcher
•
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 66)
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 68), which is explained further on.
LineWork Tuning
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 92).
6.3.2 Queue defaults
A FlexRip can have several queues of:
32
Dispatcher
•
•
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 44) chapter for more details on queue settings. (The different
tabs look exactly the same).
The priority of the settings (page 44) 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.
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.
33
Dispatcher
6.4 Tools menu
The Tools menu contains the following items:
1. History View (page 34)
2. Status Monitor (page 34)
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.
34
Dispatcher
6.5 Info menu
The Info menu contains the following items:
1. Ports (page 35)
2. About Dispatcher (page 35)
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).
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.
35
Dispatcher
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 112)'.
•
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
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:
36
Dispatcher
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.
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 39).
37
Dispatcher
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.
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
38
Dispatcher
be copied.
6.7.2.1 General
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).
39
Dispatcher
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.
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
40
Dispatcher
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.
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.
41
Dispatcher
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:
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.
2.
Click the Hot Folder and click the Queue Info button.
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
42
Dispatcher
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.
43
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” setting
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:
44
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.
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.
45
Queue Settings
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 (FlexRip Information Database). 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 Resolution
Here you can specify the expose resolution of the job. The values in the dropdown
list are specified in PPI (Pixels Per Inch). The resolution chosen here will be identical
to the resolution the file will be exposed with. This field should be set to (none) if
the decision is left to the operator.
7.2.3 Rotation
For PS/PDF or native input (Hot Folder, AppleTalk or Named Pipe) it is possible to
preset a rotation.
7.2.4 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 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.
46
Queue Settings
7.2.5 Page size
Page size options allow you to overrule the size of the input file. It is also advised to
leave this on 'none' as the output file is best the size that was determined in the
application. Overruling the size of the input file might influence the positioning of
the output on film or plate.
Warning
Never leave it on Custom page size, which takes the maximum size for that device.
This means that it will always create output files as big as the drum surface.
7.2.6 Imaging options
7.2.6.1 Image
Here you decide on either a positive image or a negative one. Outputting to the CDI
requires a positive image. When set to 'none', this setting will be read from the
PostScript file or server ticket. Also see the Priority of Settings (page 44) chapter.
Warning
When defining 'positive' in both PostScript file/ticket and in the Queue Settings the
result will be 'negative'! As you cannot select 'none' in the PPD, we advise you to
leave this setting in the Dispatcher queue to 'none' and let the operator decide this in
the PostScript file or server ticket! Please also see the scheme in the section
Workflow: flavors and hints (page 80).
7.2.6.2 Emulsion
Emulsion UP means: readable when the emulsion side of the film is held up.
This is an example of a positive emulsion up eps file:
Emulsion DOWN means: readable when the emulsion side of the film is held down.
47
Queue Settings
This is an example of a positive emulsion down eps file:
When set to 'none', this setting will be read from the PostScript file or server ticket.
Warning
The same problem as described for image can occur here. The decisions of the queue
and the PostScript/native file might conflict and then reverse what you expect! As
you cannot select 'none' in the PPD, we advise you to leave this setting in the
Dispatcher queue to 'none' and let the operator decide this in the PostScript
file/ticket! Please also see the scheme in the section Workflow: flavors and hints (page
80).
Note
In the PPD file, 'right reading' refers to 'emulsion up' (when reading it right) and
'wrong reading' refers to 'emulsion down' (when reading it right).
7.2.6.3 Dot Shape
Choose your dot here. When set to 'none', the dot shape in the ticket or PostScript
file will be used.
For more information on Esko screening technology, we refer to the Screening
documentation on the Esko Suite 12 DVD.

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).
Tip
If you want several output folders, then it is a good idea to create them under one
general 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.
49
Queue Settings
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
•
&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
50
Queue Settings
Designer colors will still be shown with their full name preceded by the letter 'D'.
•
&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/Proof
(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;,|
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_$M.tif
51
Queue Settings
sunshine_Dave_$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.
7.3.1.3 Restricted file names
Note
This option is not applicable to FlexRip/Approval and FlexRip/B.
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 Configuration set
7.3.2.1 Name
Specify the configuration you want to use.
Configurations are created in the FlexRip Configurator. For more information,

7.3.3 Properties
7.3.3.1 Single / Multiple file
When selecting single file output, all separations will be ripped to separate files
first. Afterwards, they will all be included in the final DCS file. This means that in
the end only one file is created.
Selecting multiple file output creates a Master file, referring to plate files. The
number of plate files to which is referred equals the number of separations.
7.3.3.2 Compression algorithm
Select the appropriate algorithm from the dropdown list. Choose between CCITT
G4 (screened only), LZW, Flate Compression, Uncompressed and None.
7.3.3.3 Enable Anti-aliasing (unscreened only)
Anti-aliasing can be enabled to smoothen text and staircase effects in images. A
factor between 2 and 8 can be specified. Note that the Rip resolution will be
multiplied with this factor to be able to smoothen and can slow down the RIP
process considerably.
Example
If your output resolution is 2400 dpi and you specify an anti-alias factor of 2, the
RIP resolution will be 4800, while the final output resolution stays at 2400 dpi.
7.3.4 Previews
7.3.4.1 Placement only
Indicates a preview (RGB) that is generated for viewing the content of the DCS file
when placing it into a DTP application. Indicate whether the file will only be used
for placement or not, and specify its resolution.
7.3.4.2 Proofable preview
Indicate whether or not you want to generate a preview (CMYK) that is used to
make a composite printout from a DTP application.

7.4 PS/PDF Input
Please note that the PPDs used in FlexRip 5.2 will not work in FlexRip 12!
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 to
support advanced screening features like stochastic screening (Monet
54
Queue Settings
Screens) and transitional screening (SambaFlex Screens). Precalculated
screens have only one disadvantage: since they have been designed and
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 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.
55
Queue Settings
Note
Because of the nature of Monet screening and SambaFlex screening it will
not be
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,
Esko BackStage, ...
For more information on how to create ScreenFilter rules, please refer to the
ScreenFilter documentation.
Note
Selecting (none) creates a FlexRip 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.
7.4.1.4 Enable optimization
Should be set to ‘Yes’.
Example
56
Queue Settings
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.
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.
57
Queue Settings
The color of objects like line art 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 to end 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,...).

7.6 InkPlanner
Select the Plate Settings (.ini) file from the dropdown list.
For more information on InkPlanner consult the InkPlanner User Manual.
7.7 Curve Pilot
The Curve Pilot tab allows you to specify press dot gain compensation, assuming
that the plate dot gain compensation will be specified in the FlexRip Configurator,
attached to the media selected in the configuration used.
60
Queue Settings
7.7.1 Press dot gain compensation
The Press Dot Gain Compensation group allows you to specify a 'single curve' DGC
and/or an 'automatic' compensation strategy from the SCRDGC’s, ICPRO’s or
.PRSYNC’s available in the list.
For more information on how to create dot gain compensation files, please see the
dedicated Esko Curve Pilot documentation on the Esko Suite 12 DVD.
What if you specify both a dgc (single curve) and a scrdgc or a Strategy/Curve Set
(automatic compensation)?
Then the curves are executed in a specific order: first the scrdgc or Strategy/Curve
Set, then the dgc. This also happens when e.g. a dgc curve was specified in the
Macintosh print menu and a scrdgc curve or a Strategy/Curve Set was set in the
Dispatcher's Queue settings. The first one is not executed in the PostScript file but
written as a reference in that PostScript file, the same way as a scrdgc or a
Strategy/Curve Set selection in these queue settings is also a reference to the rip.
Why you have to specify a separate scrdgc/dgc curve or a Strategy/Curve Set is
explained by the FlexRip instructor. To a large extent, this depends on your
previous and current workflow. The Esko Curve Pilot documentation is a good
61
Queue Settings
guideline to help you answer these questions. To get a good idea of what exactly
happens when you use both tools, just make a drawing of the 2 curves: put the
scrdgc first, the dgc curve next to it and follow what happens to a specific
percentage.
7.7.2 Calibration
When the output device is not linear (i.e. 50% does not come out on film/plate as
50%) gamma compensation allows you to correct this.
Please see the specific documentation on how to calibrate your device. It can be
found on the Esko Suite 12 DVD: &quot;determine_gamma_english.htm&quot;
7.8 PS/PDF marks
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.

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.
7.8.2.3 Data legend
Check the boxes to indicate which items you want to include in the data legend. Use
the text field to enter user-defined text.
Note
There are no requirements concerning the text layout. Be aware that template
variables do not work for the data legend field.

7.9 Screening
This tab allows you to overrule screen parameters for each separation. The default
option is (none). This means that the RIP will use the screen parameters specified in
the job. Change these values only if you want to override the screen parameters
specified in the job.
FlexRip offers an elaborate screening overrule mechanism to add more flexibility. It
is possible to define spot colors and designer colors with LPI/angle/dot shape
information. Moreover, the screening routines have been optimized to give more
consistent output. E.g. dots with the same number of pixels will now have an
identical shape (within the same dot shape).
Note
In case of PostScript input it serves both composite and separate PostScript. This
screening menu should be seen as a filter after reading the input data and before the
start of the actual ripping.
Select the color of which you want to change the settings in the list and apply the
changes by selecting the correct Dot Shape, LPI or angle from the dropdown lists.
65
Queue Settings
To define/add individual spot colors:
1. In the Ink book, select the book you want, or ‘(Unregistered inks)’ if the spot
color is not registered in your color database.
2. Enter the name of the spot color in the Ink name field.
What happens if you do not use these settings?
Then all rules previously mentioned are valid. The angle and ruling settings will be
taken from the incoming PS/PDF file. In case of EskoLink input, the settings of the
ticket will be taken.
What happens if you do use these settings?
If you select a Dot Shape and/or enter an angle and/or ruling value, the RIP will take
these into account and will overrule all other incoming or requested values
(overwriting the settings in the PostScript file or server ticket). This means that
whatever you enter here will get the highest (overruling) priority!
Warning
Any Dot Shape entered in the Screening tab will overrule the Dot Shape selected in
the Basic tab.
When should I use this menu?
When you do not control the incoming options:
• When you did not create the PS/PDF yourself and noticed that it contains
ruling settings that are not supported by Esko screening rules.
• When you have a special workflow in which you want a special Dispatcher
queue executing a fixed set of screening rules (contrary to a queue that
listens to job-related settings).
7.10 Debugging
This tool enables you to control the content of the log files. You can make your log

66
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 double-clicking 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_flexripdcs_v120\dcs\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.

7.11 Copydot Tuning
7.11.1 Background
7.11.1.1 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.
7.11.1.2 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.
7.11.1.3 Copydot and paint modes
A bitmap image can be set in 3 different modes:
1. ImageMask
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!
7.11.2 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.
69
Queue Settings
This will give you four extra tabs in the Dispatcher, one of which is the ‘Copydot
Tuning’ tab.
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
70
Queue Settings
image must have at least 1000 rows or columns.
7.11.2.1 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.
7.11.2.2 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.
7.11.2.3 Use Copydot preview (Unscreened only)
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.
71
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.
72
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.
73
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.
74
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. 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.
75
History View
'Save As...' in the Server menu will save the currently selected log file.
76
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...
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_flexripdcs_v120\dcs\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.
77
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 66) 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.
The RIP will take the requested PostScript file screening settings and the log
78
History View
•
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 12.0 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.

Workflow: flavors and hints
10 Workflow: flavors and hints
10.1 Who decides: FlexRip or the operator?
You will have noticed that there are several ways to work with FlexRip (See the
Priority of Settings (page 44) chapter).
•
•
•
Some people want 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 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 Emulsion: up or down, positive or
negative?
An advantage of the FlexRip mechanism is that it can be tuned to everyone's
desires. You can make it listen to settings or you can make it 'correct' possible errors
in incoming settings. Just because this is possible, we have some extra advice on
what happens when multiple settings seem to conflict (= 'where they do not follow
the described priority').
We explained that the FlexRip Dispatcher settings have the highest priority. They
will overrule all others coming in. Unfortunately, there are some exceptions as
mentioned before in the section Queue Settings Basic (page 45). These remarks are
only about the basic settings 'Image' and 'Emulsion'. All other settings have the
general behavior as described in the section Priority of settings (page 44).
The initial problem here is that the FlexRip Dispatcher has to live with the rules of
the 'PostScript' language and that this general language is being written from
80
Workflow: flavors and hints
several sources/DTP applications. This means that we have 3 parties involved: The
DTP application, the PostScript file and the FlexRip.
In the following schemes, we will explain what happens if you tried out all the
interactions of the possible settings. Each scheme ends with a general rule: use those
rules to set up your fixed workflow. Do not trouble all DTP operators with the
jungle of possibilities in the settings.
The following situation can cause confusion. When choosing Print in Freehand (or
any DTP application), you can always set the emulsion up or down in the Freehand
print settings. Further down in the print options (you selected an Esko device PPD),
there are the 'Printer Specific' settings of the output device where you can also select
an emulsion setting (and there is no 'none' to choose). The result of these two
settings will eventually end up in the written PostScript file. It is this setting that is
then taken into account or overruled by the Dispatcher Queue settings.
A first scheme now describes what happens between application and PPD choice. A
second scheme describes the interaction between the PostScript file and the
Dispatcher Queue settings.

10.4 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.
83
Screening on FlexRip
11 Screening on FlexRip
(screened only)
For complete and detailed info on Esko Screening, we refer to the screening
documentation on the Esko Suite 12 DVD.
In case of 'Precalculated' screening (native as well as PostScript input), the following
should be considered:
The 'jump to' mechanism
The range of possible LPI’s that the PPDs offer is a selection. The FlexRip will jump
to the nearest LPI value that it has available. So if you ask 100 LPI and the RIP offers
94 and 104, you will get 104 LPI. Do remember that you cannot combine
precalculated screening with DynaCell or PostScript screening. If you want another
print angle or LPI than Esko offers, you can no longer combine it with an Esko dot
shape.
Please refer to the Screening tab for more information on overruling.
See the ScreenFilter documentation on the Esko Suite 12 DVD for information on
how to swap PostScript screens with Esko screens.

Esko Curve Pilot: Esko’s Dot Gain Compensation tool
12 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 Esko Suite 12 DVD.
12.1 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 12.0 will not create SCRDGC’s anymore.
12.2 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.
85
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.
12.3 Where are my SCR(DGC) files and
Strategies?
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 (scr)dgc files and Strategies will be located on the server. If
you do not, they are stored locally on the FlexRip.
86
Esko Curve Pilot: Esko’s Dot Gain Compensation tool
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 Esko 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.
12.4 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 Esko Suite 12 DVD for more
elaborate information.
87
Data backup and customization
13 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 a FlexRip 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.
88
Classic errors and their explanation
14 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
89
Classic errors and their explanation
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'.
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.
14.1 Classic PostScript errors
14.1.1 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
90
Classic errors and their explanation
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
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
Esko 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.
•
Page
•
Ink name descriptions
W_CLASS
Warning: Multiple invocations of PLATECOLOR on this
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)
14.1.2 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
91
Classic errors and their explanation
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.
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_flexripdcs_v120\dcs\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.
14.2 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

Classic errors and their explanation
screen file and those have a name starting with an 'o'.
93
Classic errors and their explanation
•
(Scr)dgc files not found
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.
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
15 General troubleshooting
15.1 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_flexripdcs_v120\dcs\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.
15.2 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.
95
General troubleshooting
15.3 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.
15.4 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.

Frequently Asked Questions
16 Frequently Asked Questions
16.1 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.
16.2 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.
16.3 FlexRip and output device controller on
the same computer
Can I put FlexRip software on the output device controller box or vice versa?
In theory you could, but this could seriously trouble your workflow. A multiple
CPU PC might permit the setup (by Esko) of a working workflow.
Please consult your Customer Service department to investigate this for you.
16.4 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.
98
Frequently Asked Questions
16.5 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.
99
Frequently Asked Questions
16.6 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.
16.7 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.
16.8 Info on the network address
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.
16.9 DCS files in PhotoShop
Why can I not open the DCS files made by FlexRip in PhotoShop?
This is normal as none of the compression schemes used in FlexRip (Group4, LZW
and Flate) are supported in PhotoShop. These compression schemes are supported
in PhotoShop for TIFF files, but not for DCS-EPS files. For DCS-EPS files, PhotoShop
only supports Jpeg compression, which is a lossy compression type that is not
suited for FlexRip purposes. Non-compressed, unscreened FlexRip/DCS files can be
opened in PhotoShop provided the image does not exceed the 30000 pixel limit
horizontally or vertically.
Non-compressed, multichannel screened FlexRip/DCS files cannot be opened in
PhotoShop but when you have the multifile DCS version (i.e. one masterfile + one
separate file per separation - this is selectable in FlexRip), you can open the
individual plates in PhotoShop provided that the image does not exceed the 30000
pixel limit horizontally or vertically. Failure to meet these conditions might result in

Frequently Asked Questions
PhotoShop loading the low resolution preview (if there is one present) stored in the
master part of the DCS file without warning.
16.10 Digital Cromalin/WaterProof settings
What settings should I use for a Digital Cromalin/WaterProof ?
Two configurations are possible:
1. FlexRip/DCS writes to an output folder on a local disk (See Output location (page
49)).
2. FlexRip/DCS writes directly to a Hot Folder of the Digital Cromalin/WaterProof.
(See Printing DCS files on a Digital Cromalin/WaterProof (page 101)
In both cases the settings should be as follows:
1. Choose a single DCS file.
2. Switch off all previews.
3. Choose a resolution that corresponds with your device (305dpi, or 610 dpi).
101
Frequently Asked Questions
16.11 Printing DCS files on a Digital
Cromalin/WaterProof
How are DCS files printed on a Digital Cromalin/WaterProof?
1. FlexRip/DCS writes to an output folder on a local disk (See Output location (page
49)). The DuPont software will pick up the output file(s) from the output using
FTP. This FTP program transfers the output file(s) to a Hot Folder on the SUN,
which controls the proofer. Once the file(s) has/have been transferred, they will
be processed and proofed. Please contact Dupont to set up this transfer.
Warning
The FTP transfer program is standard only from version 5.0.3 onwards.
2. FlexRip/DCS writes directly to a Hot Folder of the Digital Cromalin/WaterProof.
FlexRip/DCS can write directly on the SUN, provided the hard disk is mounted
on the FlexRip (via &quot;Map Network drive&quot;). The disk can only be mounted if the
Samba software (enabling the connection between UNIX and Windows) is
installed on the SUN. The following Hot Folder can be used:
/stork/gateways/import_dd. Please contact Dupont to set up this configuration.
3. In an Automation Engine environment, FlexRip/DCS writes to an output folder
or a local disk and Automation Engine FTPs the file to the SUN computer.
16.12 Changing extensions of external files
How do I change the extension of an external file?
The extension of external files is the short ink name of the ink they represent. In case
of Pantone, the Pantone number will be mentioned, and designer inks will be
represented as a D, followed by the designer ink name. It is, however, possible to
change the extension of an external file by setting up the environment variable
FLEXRIPDCS_PLATEFILE_EXTENSION in the FlexRip Configurator. Enter the new
extension (e.g. .tmpeps) as value for the environment variable.

17.1.2 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.
•
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.
17.1.3 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’.
110
Appendix
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.
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 a FlexRip workflow and
have noticed file-transfer 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.
17.1.4 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:
111
Appendix
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 a FlexRip'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).

17.2 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.
17.3 What about OPI?
112
Appendix
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 a FlexRip, 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
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 pre114
Glossary
calculated 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 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).
115
Glossary
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
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.
