Pack Proof
2. What is Pack Proof?
Pack Proof is a proofing software solution that enables you to proof your jobs on the most commonly used proofers in the market, using the proofers’ native language.
Pack Proof is integrated with Automation Engine, so you can send a job through your proofing workflow to the proofer without having to leave the Automation Engine Pilot.
On top of that, Pack Proof ensures color accuracy:
• Color management ensures color matching throughout your workflow, thanks to Esko’s
Color Engine Pilot.
• Verification allows you to add a color strip to your proof and, if you have a verification license (optional), to verify the strip's color accuracy using a measuring device and the Esko
Verification software.
2.1 The Pack Proof Workflow
6
1.
When sending files to Pack Proof's Proof for Contract Approval task , you can:
• Perform general file transformations to make sure the output is as expected (select the right page box, rotate/invert/mirror/scale the file as needed...).
• Color manage your file so that your proof accurately reflects what your press output will look like (using color management settings from Color Engine Pilot ).
•
Rasterize the vector graphics to continuous tone bitmaps (using Imaging Engine's
RIP'ing capabilities).
Rasterizing Vector Graphics to Bitmaps
on page 13.
• Set verification options to later verify your proof's color accuracy using Esko
Verification.
Pack Proof
2. The Proof for Contract Approval task sends the files to be proofed to the Esko Proof
Server .
3. The Esko Proof Server proofs the file on the proofer of your choice. This proofer can be one of many types of proofing devices supported by the Esko Proof Server.
4. If you have a verification license, you can verify that the colors on your proof match the colors you were expecting, using a
measuring device and the Esko Verification software
.
See the
Esko Verification documentation
for more information.
2.2 Color Management
Color management is making sure that colors are reproduced consistently at different stages of the printing process.
This consistency is especially important for specific "brand" colors, that have to look the same when printed on different substrates (cardboard, paper, plastic...).
2.2.1 Devices and Color Spaces
Different devices (a digital camera, computer monitor, proofer, press...) display or reproduce colors in different ways.
Colors in photographs are generally defined in the RGB color space (Red, Green, Blue), and monitors also use RGB to display colors.
Proofers and presses use CMYK (Cyan, Magenta, Yellow and Black -or "Key") for printing, and sometimes additional inks (for example Orange, Green and Blue, to be able to reproduce more colors, or one or two spot colors -generally Pantone inks- used in a particular file).
Files coming from a graphic designer may contain CMYK, spot colors and sometimes images in
RGB.
2.2.2 Devices' Profiles
Even within one color space, different devices can reproduce colors differently. For example, two CMYK proofers from different brands may print completely differently.
A device's gamut is the totality of the colors that device can reproduce (for example, the area shown in light green below).
2
7
2
Pack Proof
This is captured in the device's profile, which describes all the colors achieved when using different combinations of percentages from the base colors (RGB, CMYK, or CMYK + extra colors).
To create a profile for a press or proofer, you need to print and measure a profiling chart containing these combinations of percentages.
8
See the
Color Engine Pilot documentation
for more information about creating profiles.
Pack Proof support the following types of device profiles:
• Esko profiles, created in the Color Engine Pilot,
• ICC profiles, created in a third party application and written in a standard format.
2.2.3 Using Profiles for Color Management
You need to have a profile for each of your devices to perform color management.
Pack Proof
2
Note:
Proofers and presses' profiles need to reflect the device's exact printing characteristics (inks, substrate...).
So if for example you change your substrate, you need to make a new profile taking that substrate into account.
Once you have made the profiles, you can perform a controlled conversion of the colors between the different device profiles.
For example if you are printing a photograph, you need to convert its colors from the digital camera's RGB profile (the source profile) to the printer's CMYK profile (the destination
profile).
This means that every color in the source profile is converted to the closest possible color that can be reproduced by the destination profile.
Note:
If you want to proof a file that will be printed on your press, you are trying to reproduce your
press' colors on your proofer.
This means that the press profile is your source profile, and the proofer profile is your
destination profile.
2.2.4 Color Strategies
If you want to refine your color management, you can use color strategies.
A color strategy is a bundle of color management settings that contains at least the source
of the devices you are using, and can contain other color management
settings (for example a
spot colors and the background color, other settings for converting specific spot colors, etc).
Your company's color management expert can create these color strategies in the Color Engine
Pilot, and you can simply select the one you need in your proofing ticket.
9
2
Pack Proof
For more detailed information about Color Strategies, see the
Color Engine Pilot documentation
.
2.2.5 Rendering Intents
A
Rendering Intent is a part of your
that handles the conversion of
spot colors and of the background color.
Each of the four rendering intents available does this in a different way, so you should choose the one that is more adapted to the way you are printing and the result you want to achieve:
• Use the Relative Colorimetric rendering intent if you don't want to simulate the source background (the point that has 0% of all inks in the source profile).
This will proof your file as if the proofer substrate was exactly the same as the substrate defined in your source profile.
For example: your press prints on cream colored card stock whereas your proofer prints on bright white paper, but you don't want to simulate the cream background on your proof.
10
With this rendering intent, colors from the source profile that cannot be reproduced by the proofer will be converted to the closest color(s) the proofer can reproduce.
In some cases several colors will be converted to the same color, which means that you can sometime lose some detail, especially in dark saturated areas and the dark parts of gradations.
Pack Proof
2
Note that typically the proofer profile has a bigger gamut than the press profile, so there are not many colors that the proofer cannot reproduce.
• Use the Absolute Colorimetric rendering intent if you want to simulate the source background to get as exact a color match as possible.
For example: you do want to simulate the cream colored card stock used on your press on your proofer substrate, to see how the final output will look like.
As with the Relative Colorimetric rendering intent, colors from the source profile that cannot be reproduced by the proofer will be converted to the closest color(s) the proofer can reproduce, meaning you can sometime lose some detail, although there are typically not many press colors that a proofer cannot reproduce.
• Use the Perceptual rendering intent if you are not trying to get an exact color match but want the proof to look visually pleasing.
If there are colors from the source profile that cannot be reproduced by the proofer, this will shrink the source gamut to fit inside the gamut of the proofer, so that all colors are converted (even the colors already in the proofer's gamut), but the relationship between colors is kept.
11
2
Pack Proof
This means that colors won't be really accurate, but you won't lose detail in dark saturated areas or gradations.
This rendering intent is most commonly used in commercial printing (for newspapers, magazines, posters...).
• Use the Saturation rendering intent if you mostly want to make sure the colors on your proof are saturated enough.
Colors from the source profile that cannot be reproduced by the proofer will be mapped onto close saturated colors that are in the proofer's gamut.
This rendering intent is most commonly used for business presentations containing graphics, or cartoons/comics.
Note: You can only use a Perceptual or Saturation rendering intent if you are working with
source and destination profiles.
2.2.6 The Color Management Database
All your
and inks are stored in a color management database (also called "CMS database").
You install this color management database when installing Automation Engine. You can install it on your Automation Engine server or on another server (the server you install your color management database on is called the "resources server").
After this, the profiles, color strategies and inks in your color management database are automatically available in the
Proof for Contract Approval task
12
Pack Proof
2
Important:
You should also install the Color Engine Pilot when installing Pack Proof.
This will enable you to create your own profiles, color strategies and inks, and to access
(if you have a PantoneLIVE license).
2.2.7 PantoneLIVE
PantoneLIVE is a database of Pantone inks in the cloud. It contains information about how different tints of an ink look like, and how the ink will look like on different substrates.
Because it is in the cloud, the same color data is accessible to every actor of the packaging production, globally (while being protected by a login). This ensures that you get predictable and accurate color every step of the way, saving time and costs.
To use PantoneLIVE inks, you need the Color Engine Pilot and a PantoneLIVE license.
After logging on to the PantoneLIVE cloud from the Color Engine Pilot, you will be able to download PantoneLIVE ink books from the cloud, and use PantoneLIVE inks in your files.
Please see the
Color Engine Pilot documentation
for more information about accessing
PantoneLIVE ink books.
Note:
If you don't have a PantoneLIVE license, any PantoneLIVE ink in your files will be treated as an unregistered ink (an ink not present in your color database), and you will not be able to proof or RIP it accurately.
In this case you should ask the file's designer to replace the PantoneLIVE ink by an ink that is present in your color management database.
2.3 Rasterizing Vector Graphics to Bitmaps
Files coming from a graphic designer may contain vector graphics or "linework" (especially for fonts or logos).
Vector graphics are highly scalable without any loss of quality (as they are not based on pixels but on mathematical formulas), but they are not printable.
To be able to print those graphics, you need to rasterize them with a RIP (Raster Image
Processor). This means converting them to bitmap images, or "contones" (continuous tone images), which are based on pixels.
13
2
Pack Proof
Low-resolution bitmaps can look pixellated, but Pack Proof generates high-resolution bitmaps.
2.4 Verification
Once you have color managed and proofed your file(s), you may want to check the color accuracy of your proof. This is especially important for contract proofing, as it is a measure of the proof's quality that you can show your customers.
Provided you have a verification license, you can do this in Pack Proof the following way:
1. Before proofing, you define
(how close the colors on your proof
must be to the colors in your input file for you to accept the proof as color accurate).
2. When proofing your file, you add a
, containing patches of the separations present in your input file.
3. Once your file is proofed, you measure this verification strip in
Esko Verification
, with a
.
4. In Pack Proof, you get detailed
about whether the measured separations are within your tolerances, helping you decide to either accept or reject the proof.
Tip: You can also use verification to monitor your proofer's stability over time (for example by printing a test job with a verification strip at regular intervals).
2.4.1 Choosing Color Deviation Tolerances
Quantifying Colors
The Lab Color Space
Colors are generally defined by their position in the Lab color space, which is a 3D color model representing all colors visible to the average human eye (developed by the Commission
Internationale de l'Eclairage).
It is based on three axes:
• the L axis (going from 0 to 100) defines the lightness of the color (a dark color has a low L value, a light color has a high one),
• the
a axis (going from -128 to 128) defines how green or red a color is (a greenish color has a low
a value, a reddish color has a high one),
• the b axis (going from -128 to 128) defines how blue or yellow a color is (a blueish color has a low b value, a yellowish color has a high one).
14
Pack Proof
2
For example:
Color
light yellow dark green medium gray
Lab values
Lab (100, 0, 60)
Lab (15, -128, 0)
Lab (50, 0, 0)
Difference Between Colors: Delta E
The difference between two colors is the difference between their respective positions on the L, a and b axes. This difference is called the Delta E (or ), and is calculated using a mathematical formula.
15
2
Pack Proof
16
The more different two colors are, the higher the Delta E number is. Generally a human eye can perceive color differences that are above 2 Delta E.
Note:
There are several Delta E formulas, that have been developed at different points in time ( CIE76,
CMC, CIE94 and CIE2000).
• If your company is already using one of those formulas, we recommend that you use the same one.
• If not, you should use the most recent one, CIE2000, which is the best reflection of the visual difference between colors.
• However, if you are trying to verify a proof according to the ISO 12647-7 proofing standard, you should use the formula specified in the standard, CIE76.
Difference Between Colors: Other Measures
Apart from Delta E, there are additional color differences indicators, that measure other colors characteristics.
You can use those if you want to have a more comprehensive picture of how well your colors are reproduced, or to quantify a particular color problem of your press.
Delta CH
Delta H
Use this to measure the difference in saturation (or "chroma") between the colors in your job and the printed colors.
This is based on the positions of the two colors on the a and b axes in the Lab color space, and can be a good indication of whether the gray balance on your press is good or not.
Use this to measure the difference in hue between the colors in your job and the printed colors.
The hue is the angle between two colors relative to the a and b axes in the Lab color space.
Pack Proof
2
Delta T
Use this to measure the difference in colorimetric tone value between the colors.
Colorimetric tone value means that the dot gain is measured by a spectrophotometer instead of a densitometer.
This gives more information about the colors (for example 50% of a warm yellow and 50% of a cold yellow look the same to a densitometer, but different to a spectrophotometer).
This is only applicable to the primary colors (CMYK).
2.4.2 Choosing a Verification Strip
You can choose from different types of verification strips to add to your job.
Keep in mind that the type of strip you can use depends on:
• what is available on your Esko Proof Server (by default, the Esko Proof Server comes with a large number of strips),
you will use to measure your strip (as different spectrophotometers
support different strip types).
This means that depending on your way of working, you will see a certain subset of the strips mentioned below.
Esko Strips
• Esko Strip: this strip type contains the following CMYK patches:
• patches of C, M and Y at 100%, 70% and 40%,
• overprints of C and M at 100%, 70% and 40%,
• overprints of C and Y at 100%, 70% and 40%,
• overprints of Y and M at 100%, 70% and 40%,
• an overprint of CMYK at respectively 100%, 40%, 40% and 20%,
• an overprint of CMYK at respectively 40%, 100%, 40% and 20%,
• an overprint of CMYK at respectively 40%, 40%, 100%, 20%,
• patches of K at 0%, 20%, 40%, 70% and 100%.
17

Proof for Contract
Approval task has a Send to Proof Server subtask; it has a green check when the files have been sent to the Proof Server.
• After measuring and verifying your strip: you can see either Verification successful or
Verification failed .
You can see verification details in the log file (which color deviation tolerances and Delta E formula you used, which tolerances were met or not met...).
On the Proof
on the proof itself.
This report shows information relative to the proof and verification (the printer used, the date and time, the verification strip used, the tolerances and whether they were met...).

You may see other error messages in some cases, but you will always get some advice as to what you need to do (for example with the
Missing resource for Imaging Engine
on host message, you will get advised to Please reinstall the Imaging Engine).
Note: You can Stop and Start Imaging Engine from here for troubleshooting purposes, but this is generally not necessary, as Imaging Engine starts automatically, and will restart automatically in case of a crash or after being force quitted.
c) Set the Number of Workers. This is the number of parallel processes used to work on multiple pages of a file, or multiple files at the same time.
Note:
The maximum number of workers you can set depends on your license and on the number of cores on your server.
Please see the
system requirements page
for details.
5. If you are only using Imaging Engine for Pack Proof (you don't have a fully-fledged Imaging
Engine to output RIP'ed files), you don't need to configure the Settings tab, or the Queue tab.
6. In the left pane, select the Imaging1 entry, go to File > Rename and give it a meaningful name.
You can also select it and press F2 (on PC).
7. Go to File > Save or use Ctrl+S (on PC) to save your configuration.
3.3.2 Pack Proof Configuration
This configuration will connect your Automation Engine server (and Pack Proof) to your Esko
Proof Server, so that Pack Proof can send files to the Proof Server, for proofing on your device.
For more flexibility, you can connect to several Proof Servers, and have access to all the workflows configured on these Proof Servers. When sending files through the
Proof for
Contract Approval task, you can then select which workflow of which Proof Server you want to use.
Important: You need to perform this configuration before you can use Pack Proof.
1. In the Automation Engine Pilot, go to Tools > Configure .
2. Select Proof Servers in the left pane.
3. For each Proof Server that you want to connect to: a) Click Add at the bottom of the right pane.

4. The Proof for Contract Approval Task
, you can use the Proof for Contract Approval task to:
• Perform general file transformations to make sure the output is as expected (select the right page box, rotate/invert/mirror/scale the file as needed...).
• Color manage your file so that your proof accurately reflects what your press output will look like (using color management settings from Color Engine Pilot).
on page 7.
• Rasterize the vector graphics to continuous tone bitmaps (using Imaging Engine's RIP'ing capabilities).
Rasterizing Vector Graphics to Bitmaps
on page 13.
• Set verification options to later verify your proof's color accuracy using Esko Verification.
For more information about Esko Verification, please see the
Esko Verification documentation
.
The Proof for Contract Approval task sends the ready-to-proof files to the workflow of your choice on the Esko Proof Server, who then proofs it on the proofer connected to that workflow. This proofer can be one of many types of proofing devices supported by the Esko
Proof Server.
Note:
To use this task, you need to have created a Proof Server workflow in the Esko Proof Client, and that workflow must:
• be connected to the Admin user,
• be connected to a physical proofer (you cannot use the predefined "Esko Linearization" workflow for example).
For information about creating a Proof Server workflow, please see the
Esko Proof Client documentation
.
Attention:
You can use several Proof Servers, but in this case, make sure that every workflow has a unique name, even across Proof Servers.
If there are workflows with the same name on several Proof Servers, you will not be able to send files to those workflows through Pack Proof.

Using the Proof Server Workflow Parameters
If you are using a Proof Server workflow that already has proofing parameters defined (for example the number of copies to print, or the rotation or scaling to apply to your file), those parameters will be filled in by default in the Proof for Contract Approval task, so that you don't have to go check them in the Proof Server workflow and copy them into the task.
Note: This is not the case if you are using a SmartName or a public parameter to select your
Proof Server workflow.
You can of course change those parameters as desired in the
Proof for Contract Approval
task.
4.1 General
1. Define what Page Box of the input PDF you want to proof.
You can either select Media Box, Trim Box, or insert a SmartName that must resolve to either media or trim.
After selecting your file's page box you will see its dimensions under the Page Box option.
2. If your input file is a multi-page PDF, select which Pages you want to proof: a) First select All pages, Odd pages only or Even pages only in the Pages option.
You can also insert a SmartName resolving to either All, Even or Odd.
b) Then you can refine your selection by entering page numbers or a Page Range.
You can separate page numbers by a comma, or use a dash to indicate a page range (for example 3,6-9). You can also use a SmartName resolving to page numbers and/or page ranges using this same format.
Note:
• Page numbers are always physical pages. If your document starts with page 5, you should not use 5 but 1 to get the first page.
• If you enter page numbers that are not part of your document, they will be excluded from the output (all the other valid pages will be proofed).
• If you enter the same page(s) more than once (for example 1,1-2), it/they will only be output once.
• Pages are proofed in the order of the document (entering 5-1 will be automatically changed to 1-5).

You can also click or Edit... to insert a SmartName that must resolve to 1 or true (to invert the output), or to 0 or false (to leave the output as it is).
Tip:
If that setting is already defined in your

You can of course change it as desired.
4. If you want to mirror your output so it is compatible with the output device or software system that will process it, click .
You can also click or Edit... to insert a SmartName that must resolve to 1 or true (to mirror the output), or to 0 or false (to leave the output as it is).
If that setting is already defined in your Proof Server workflow, it will be filled in by default.
You can of course change it as desired.
5. If you want to add a SmartMark to your output file(s), select it in the SmartMark list, or use a SmartName that will resolve to the SmartMark name.
A SmartMark is a mark whose content is variable, so you can make it display information about that specific job. For example, you can include some of the parameters used during
RIP'ing in your output file(s) by using a SmartMark.
You need to: a) First create the SmartMark you want to use in PackEdge (see the SmartMarks section in the PackEdge manual for details).
You can create either:
• a SmartMark with proof-specific parameters,
to display this value from the Pack
Proof parameters:

• another type of SmartMark (for example a corner mark).
If your PackEdge application is linked to your Automation Engine server, your SmartMark will automatically be saved in the correct location and will be available in Pack Proof.
b) Then select that SmartMark in your Proof for Contract Approval task.
The SmartMark will be added to each proof generated from your input file.
4.2 Proofer
to which the task sends your RIP'ed
output.
• In the Proof Server Workflow list, you can see all of the valid workflows found on the Proof
Server(s)
Note:
To be valid, your Proof Server workflow must:
• be connected to the Admin user,
• be connected to a physical proofer (you cannot use the predefined "Esko Linearization" workflow for example).
For information about creating a Proof Server workflow, please see the
Esko Proof Client documentation
.
Pack Proof checks whether the Proof Server and the selected workflow are available when defining ticket settings and when (re-)launching the task.
The task will end in error if it can't access the Proof Server workflow or if the workflow is invalid.
Attention:
If you are connected to several Proof Servers, make sure that every workflow has a unique name, even across Proof Servers.
If there are workflows with the same name on several Proof Servers, you will not be able to select any of those workflows here (the name will be greyed out).
You can:
35
4
Pack Proof
• select a workflow from the list,
• use SmartNames (that must resolve to the name of a valid Proof Server workflow),
• set the workflow using public parameters.
Tip:
If you select a workflow from the list, its proofing parameters (number of copies to print, rotation or scaling to apply to your file...), will be filled in by default in the
Proof for
Contract Approval task, so that you don't have to go check them in the Proof Server workflow and copy them into the task.
You can of course change those parameters as desired in the
Proof for Contract Approval
task.
4.3 Transformations
Use the Transformations settings to scale or rotate your output relative to your input file.
Tip:
If you are using a
that already has scaling and/or rotation parameters defined, those parameters will be filled in by default, so that you don't have to go check them in the Proof Server workflow and copy them into the task.
You can of course change those parameters as desired.
1. If you want to Scale your input file's contents, select either:
• Scale by percent and enter the vertical and horizontal scaling percentages to use (they must be between 10% and 1000%).
Note:
By default, you enter the vertical scaling percentage and the horizontal one is calculated automatically to keep the proportions.
If you want to enter the horizontal scaling percentage manually, click to unlink it from the vertical one first.
However, if you do this then link the percentages again, the last percentage you entered will be kept, and the other one will be recalculated automatically to keep the proportions.
• Fit to page size to fit your output to the substrate defined in your
, while keeping the proportions (this will fit it to either the width or the height of the substrate, while making sure everything is on the substrate).
• Fit to page width to fit it to the width of the substrate defined in your Proof Server workflow, while keeping the proportions.
to your output, they will be taken into account when fitting the
proof to the substrate's width or size.
36
Pack Proof
4
Note:
If you have chosen to print borderless in your Proof Server workflow, Pack Proof will take this into account when fitting your output to the substrate, and make your output slightly larger to cover the whole substrate width or height.
You can only print borderless if your proofing device supports it. Please check the
Esko Proof
Client documentation
and your proofing device documentation for more information about borderless printing.
If you don't want to scale your file's contents, leave Do not scale selected.
You can use SmartNames resolving to not (Do not scale), ByPercent (Scale by percent),
FitSize (Fit to page size) or FitWidth (Fit to page width).
When entering SmartNames for vertical and horizontal scaling percentages, they must resolve to the numerical value (without the % sign).
2. If you want to rotate your file, select the Rotation you want to apply here.
You can choose to either:
• use a fixed rotation (this can be 0°, 90° Counter Clockwise, 90° Clockwise or 180°; any other value will give an error),
• rotate your file if necessary to fit, or fit better, on the substrate (select
Minimal Media
Consumption). This can be useful when using narrow rolls of substrate for example.
If it did fit on the substrate already, this option makes sure that the largest dimension of the file will be placed in the substrate width, to use less substrate material when cutting.
37
4
Pack Proof
Note:
• If you have chosen to print borderless in your Proof Server workflow, the task will take the extra space into account when rotating your file to fit (or fit better) on the substrate.
• You can use a SmartName that resolves to 0, 90 (for 90° Counter Clockwise), 180, 270
(for 90° Clockwise), or minimal.
• When using a fixed rotation, you need to use a numerical value (ninety will not work).
• This is a public parameter, that you can fill in when submitting files through Shuttle.
4.4 PDF Objects
Use the PDF Objects settings to define:
• how to color manage RGB objects in your input file,
• what dot gain compensation to apply to your input file's images.
All parameters in this tab are public parameters, that you can fill in when submitting files through Shuttle.
1. In Default RGB Profile, specify the profile to use if no profile is specified for a certain RGB object in the input file. The default is srgb.icc.
You can use a SmartName that resolves to the full profile name.
2. Select Use PDF transfer curves if you want to use the dot gain compensation curves attached to the images in your input PDF.
These curves compensate for the unwanted characteristics of the device that created the images (scanner, digital camera...).
You can use a SmartName that resolves to true (to use the input file's curves) or false (to not use them).
3. If you experience issues with a font that doesn't look smooth enough at your selected resolution, your font may have font hinting errors.
Font hinting is the rendering of the outline (vectorized) font to pixels. For certain fonts, this rendering sometimes doesn't give a visually pleasing result, especially at low resolutions. In the image below, the top font has font hinting errors, the bottom font doesn't.
38
Pack Proof
Choose how to handle files containing font hinting errors:
• Leave Generate an error if the job contains font hinting errors selected if you want the task to end in error when encountering font hinting errors. You can also use a
SmartName resolving to true.
• Deselect Generate an error if the job contains font hinting errors if you want to output your file anyway, whether it has font hinting errors or not (your task will end with a warning). You can also use a SmartName resolving to false.
This may lead to reduced quality rendering of the text, but it will not generate incorrect characters in your output file.
4.5 Document Inks
Selecting Which Separations to Proof
Use the Document Inks settings to select which separations of the input file(s) you want to proof.
For example, you can use these settings to exclude technical and/or varnish inks from your output.
You can choose to proof either:
• All separations.
• A number of separations you select Manually.
• A number of separations you select by using selection criteria.
Selection criteria are rules that you define to select separations automatically for you when the task is launched on a file.
Tip: You can make the ink selection parameters public so that an operator can set them through Shuttle as needed for each job.
Selecting separations manually is the easiest option, but you can only do it on a file by file basis
(when you launch the task on a single input file).
Using selection criteria is more advanced but also more powerful than selecting separations manually, and you can do it anytime (when launching the task on one or more input files, when using the task in a workflow, when defining ticket settings...).
Therefore, we recommend that you first try selecting separations manually when running the task on individual files, then switch to using selection criteria to automate your workflow further.
Tip:
To get used to working with selection criteria, try the following on a few of your files:

Handling Unregistered Inks
Unregistered inks are inks that are not present in your
is no information about these inks apart from their RGB values in the input file, they cannot be color managed or proofed accurately.
Therefore, we recommend you exclude them from the output, especially for contract proofing.
Choose what to do in case some unregistered inks are still in the list of inks to be proofed:
• If you want the task to end with a warning, leave
Generate an error if the job contains
unregistered inks deselected.
All the inks you chose to include in the output will be proofed, but the unregistered inks will not be color accurate.
• If you want the task to end in error, select
Generate an error if the job contains
unregistered inks.
In both cases, you will also see a message in the log.
Note: If your file contains
and you don't have a PantoneLIVE license, those
inks will be treated as unregistered inks.
4.5.1 Selecting Inks Manually
Note: You can only select inks manually when you are launching the task on a (single) file, not when you are defining a generic ticket without an input file.
When choosing to Select Inks Manually, you will see a table containing all of your document's inks, showing each ink's:
Ink Name
Ink Book
Ink Index
Spot Ink Index
If an ink book is not present in your color database, it will show here as
<unregistered "">.
The Ink index is the order in which the file's inks will be printed (the ink with ink index 1 is at the bottom of the document and will be printed first).
To find the ink index of a file:
1. select the file in the Automation Engine Pilot's Files view,
2.
click ,
3. in the Info dialog that opens, select Inks in the left panel.
The order of the inks at right is the ink index (the topmost ink has an index of 1, the second of 2, etc.).
Note that if you reorder the inks by one of the columns (for example by
Ink name), they won't be ordered by ink index anymore. You will need to close that dialog and reopen it to see the ink index order again.
The Spot Ink index is the order in which a spot ink will be printed (when counting only spot inks and not process inks).
40
Pack Proof
For example, if the first 4 inks of the document are CMYK, the first spot ink will have 5 as Ink Index but 1 as Spot Ink Index.
Ink Type
This can be for example Normal, Technical, Varnish...
Printing Method
If you have set a Printing Method for an ink it will be shown here (this can be for example Offset, Gravure, Flexo... or any custom printing method you configured).
See the Automation Engine documentation for more information about printing methods.
Select the ink(s) you want to proof, or select the toggle in the table header to select/deselect all inks.
You will see a table listing the Selected document inks, and another table with the Document
inks that are not selected.
Attention: If no ink is selected, you cannot launch the task.

4.5.2 Selecting Inks Using Selection Criteria
every time, you can define some rules to automatically
select certain inks in your input file(s).
You can do this:
• either when running the task on one or more files, or when creating a task ticket to use later,
• by choosing to Select Inks by using selection criteria in the Document Inks settings.
How Does it Work?
You select the inks to be output by checking a combination of criteria:
1. You define what to check. You can check any of the following ink characteristics in your criteria:
Ink name
Ink book
Ink index
The Ink index is the order in which the file's inks will be printed (the ink with ink index 1 is at the bottom of the document and will be printed first).
To find the ink index of a file:
1. select the file in the Automation Engine Pilot's Files view,
2.
click ,
3. in the Info dialog that opens, select Inks in the left panel.
The order of the inks at right is the ink index (the topmost ink has an index of 1, the second of 2, etc.).

Spot ink index
Ink type
Printing method
Note that if you reorder the inks by one of the columns (for example by Ink name), they won't be ordered by ink index anymore. You will need to close that dialog and reopen it to see the ink index order again.
The Spot ink index is the order in which a spot ink will be printed
(when counting only spot inks and not process inks).
For example, if the first 4 inks of the document are CMYK, the first spot ink will have 5 as Ink index but 1 as Spot ink index.
This can be for example Normal, Technical, Varnish...
If you have set a Printing method for an ink it will be shown here
(this can be for example Offset, Gravure, Flexo... or any custom printing method you configured).
See the Automation Engine documentation for more information about printing methods.
For example, you can check whether the Ink book is process, whether the Ink name is yellow...
You can use as many criteria as you want.
2. You define how to combine your criteria into a rule. For example:
• If you want to output only process yellow, you should check for inks that match both of the criteria:
Ink book is process
Ink name is yellow
• If you want to output both all process inks and all yellow inks, you should check for inks that match
either of the criteria:
Ink book is process
Ink name is yellow
• If you don't want to output any process inks or any yellow inks, you should check for inks that match neither of the criteria:
Ink book is process
Ink name is yellow
How Do I Build Rules?
Build your rules the following way:
1. Choose how to combine the criteria in your rule:
• Select All of the following are true if you want to only select the inks that match all of the criteria you define.
• Select Any of the following are true if you want to select all the inks that match at least
one of the criteria you define.
• Select None of the following are true if you want to only select the inks that match
none of the criteria you define.
42
Pack Proof
2. Define your first selection criterion.
You can select an ink based on its:
• Ink name: you can define if it contains/begins with/ends with/is a piece of text
(alphanumerical characters), or if it is empty.
• Ink book: you can define if it contains/begins with/ends with/is a piece of text
(alphanumerical characters), or if it is empty.
• Ink index: you can define if it equals/is less than/is greater than the number you enter, or is is between the two numbers you enter (in this case the ink indexes you enter as boundaries are also selected).
• Spot ink index: you can define if it equals/is less than/is greater than the number you enter, or is is between the two numbers you enter (in this case the spot ink indexes you enter as boundaries are also selected).
• Ink type: you can define if it is a piece of text (alphanumerical characters).
• Printing method: you can define if it is a piece of text (alphanumerical characters).
For example, you could use:
All of the following are true
Ink book is designer
None of the following are true
Ink name is crease
None of the following are true
Ink type is Technical
Ink type is Varnish
to:
select all inks from the "designer" ink book exclude an ink called "crease" exclude all technical and all varnish inks
Tip:
• You can enter several values to check for: just use a semicolon (;) between them.
For example, to check for both inks called Cyan and inks called Magenta, choose Ink
name is and enter Cyan;Magenta.
• When launching the task on a file, you can also click to select one or more of the Ink
names/Ink books/Ink types/Printing methods used in your input file(s).
A criterion will automatically be created based on your selection.
3. Click + to add more criteria and define them.
To remove a criterion, click - next to it.
Tip: If you are launching the task on a single input file, you will see a table listing the Selected
document inks, and another table with the Document inks that are not selected under the rules you defined.

Attention: If no ink is selected, you cannot launch the task.
4.5.3 Switching How You Select Inks
You can switch between the two methods of selecting inks (
and
), and this will keep the same inks selected.
Switching from Selecting Inks Manually to Selecting Inks Using Selection
Criteria
When switching from selecting inks manually to selecting inks using selection criteria, the task will translate your manual ink selection into rules, so that the same inks are selected (you can see them in the Selected document inks table).
The rules you get are based on the characteristics of the inks you selected.
For example, if you selected all the process colors but no spot color in your file, for an offset job, you will get the following rule:
All of the following are true
Ink name is Cyan;Magenta;Yellow;Black
Ink book is process
Ink type is Normal
Printing method is Offset
Note:
If you...
• first selected inks using selection criteria,
• then switched to manual selection without changing the selection,
• then switched back to selection criteria,
... then your rules will be kept.
If you did change the selection in manual mode, the task will automatically generate new rules.
Switching from Selecting Inks Using Selection Criteria to Selecting Inks
Manually
When switching from selecting inks using selection criteria to selecting inks manually, all the inks selected by the rules you defined (the inks in the Selected document inks table) become selected manually.
Note: You can only switch to selecting inks manually when you are launching the task on a

4.6 Color Management
to your output file(s). To do this, you use a
containing your color management settings.
You can apply two types of color management, depending on the type of proof you want to make:
Standard Proof
If you are making a standard proof, you are trying to reproduce your press' output on your proofer as accurately as possible.
In this case, you should use a color strategy containing your
press profile as source profile
and your proofer profile as destination profile.
Color Management for Standard Proof
Emulation Proof
If you are working with both a regular press and a digital press, and you want to be able to move jobs between presses, you need to make sure they have comparable output.
This can be useful if you want to use your digital press instead of your main press to reprint a few copies of a job, or to print short run jobs (with the same results as on the regular press) in general.
In this case, you should make an
emulation proof, that takes both presses into account when proofing. It will:
• first simulate how your regular press prints on your digital press,
• then simulate that simulation on your proofer.
This will help you find out which colors can or cannot be reproduced on your digital press, as a digital press can have a narrower gamut than both a regular press and a proofer.
Color Management for Emulation Proof
on page 48.
4.6.1 Color Management for Standard Proof
If you are making a standard proof, you are trying to reproduce your press' output on your proofer as accurately as possible.
In this case, you should use a color strategy containing your
press profile as source profile
and your proofer profile as destination profile.
See
on page 9 for more information about color strategies.
You can either select an existing color strategy (that you have created in the Color Engine Pilot), or create a new (basic) color strategy on-demand.
Note that when creating a basic color strategy on-demand, you will only be able to use it for the current task (you will not be able to store it, edit it later or reuse it).
• If you have created a color strategy in the Color Engine Pilot, select it in the
Color Strategy
list.
45
4
Pack Proof
To be available in this list, your color strategy must be stored in the color database defined for your Automation Engine server (if your Esko software is set up correctly, the Color
Engine Pilot saved it in the right place automatically).
You can also select your desired color strategy through a public parameter, or using a
SmartName. The SmartName for the color strategy must resolve to one of the available color strategies.
The color strategies you can select depend on your proofing device:
• If your proofing device (connected to the
you selected) doesn't have a profile attached, you can select any color strategy whose destination profile
has the right ink set for the proofer (as shown in red below).
46
• If your proofing device has a profile attached, you can only select a color strategy that has that profile as destination profile.
Pack Proof

Note:
• We recommend you always use a proofer that has been profiled (for more accurate proofing, it should have been profiled or recalibrated within the last two weeks).
You can see when your proofer was last profiled, and manage your profiles, in the
Color Engine Pilot's Device Manager. See the
Color Engine Pilot documentation
for more information.
• If your proofing device has a profile attached and there is a recalibration for this profile, that recalibration will be applied when proofing.
You perform a recalibration when your proofer output has drifted compared to what it was when you created the proofer profile.
To recalibrate the proofer, you print and measure a recalibration chart in the Color
Engine Pilot. This creates a recalibration file that you can "apply" on your proofer profile to update it.
For more information about recalibration, please see the
Color Engine Pilot documentation
.
Tip:
If you are proofing files containing a white separation (for example for a white underprint) on an Epson Stylus Pro WT7900 proofer, and you want to color manage your white separation, make sure you select the color strategy you created for this purpose here.
Color Managing your Proofer's White Ink

If the input file does not contain a document profile, the Source Profile you selected will be used instead.
Important:
• If your proofing device doesn't have a profile attached, you can use any destination profile that has the right ink set for the proofer.
• If your proofing device has a profile attached, you can only use that profile as destination profile.

Pack Proof uses the output resolution defined in your
decide whether quality or speed is more important to you.
• If you have chosen High Quality in your Proof Server workflow, Pack Proof will output your file(s) at the maximum resolution supported by your proofing device (you can check this resolution in the Proof Client).
You would typically use this for your final output, where quality is much more important than speed.
• If you have chosen Standard in your Proof Server workflow, Pack Proof will output your file(s) at 50% of the maximum resolution supported by your proofing device.
• If you have chosen Fast, Pack Proof will output your file(s) at 25% of the maximum resolution supported by your proofing device.
You would typically use this for drafts, where you don't need high quality yet but want a fast result.
For more information, please see the
Esko Proof Client documentation
.
1. If you experience problems with jagged edges, for example in small text, you can set an
Anti-aliasing factor to smooth those edges.
In the example below, you can see the difference between output without anti-aliasing (on the left), and with anti-aliasing applied (on the right).
50
Pack Proof
4
You can adjust the amount of anti-aliasing applied by choosing a factor of either 2, 3 or 4
(note that using a higher anti-aliasing factor may slow down processing).
You can also set this with a SmartName resolving to None (if you don't need anti-aliasing), or to the anti-aliasing factor you want (for example 2).
Attention: Because anti-aliasing changes the output sampling to smooth the jagged edges, you cannot resample your images (with the Image Resampling option) if you use anti-aliasing.
2. If your input file contains images, the images' pixels may not map exactly to output pixels because:
• the images' resolution is different from the output resolution you chose,
• scaling and rotation effects change the size and placement of the images' pixels.
You then need to resample these images to be able to output them at the same resolution as the rest of the file.
In the Image Resampling option, choose the resampling method you want to use (you will have to make a trade-off between processing time and image quality).
• Choose From File to use the resampling method defined in the input PDF (this is the default option). This method can be either:
• the "nearest neighbor" algorithm, which keeps the image very sharp but can make it look jagged (pixellated but sharp). This is mostly recommended if you have small images with sharp lines/sudden differences in intensity, and/or you do not want your images to be fuzzy at all.
51
4
Pack Proof
52
This resampling method is very fast.
• the "PDF interpolation" algorithm, that smooths the image while resampling (see below).
Note: Most PDF files don't specify a preferred resampling method, so the default
("nearest neighbor" algorithm) is used. If you want to make sure that the "PDF interpolation" algorithm is used, choose
PDF Interpolation instead of From File in the
Image Resampling option.
You can also use a SmartName resolving to FromPDF.
• Choose PDF Interpolation to smooth the image while resampling.
With this method, you get images that are pixellated and fuzzy, so it is only recommended if you have small images with gradual differences in intensity, like photographs of nature.
Pack Proof
4
This is slightly less fast.
You can also use a SmartName resolving to PDFInterpolate.
• Choose Auto Resampling to upsample the images to an automatically calculated resolution (generally half or a third of the output resolution) before smoothing it.
When using this, images are a lot less pixellated and fuzzy.
53
4
Pack Proof
This method is quite slow but gives images of a good quality, so it is recommended in most cases (unless you want an extra sharp image, in which case you should choose
From File).
You can also use a SmartName resolving to ResampleAuto.
• Choose Full Resampling to upsample the images to the full output resolution.
This is the slowest method but gives the highest quality images (not pixellated and only slightly fuzzy).
54
Pack Proof
4
Use this if Auto Resampling doesn't give you the results you want.
Attention:
Resampling to full resolution can require significant amounts of memory when the output resolution is high (especially from 4000 dpi).
If you want to do this, we recommend that you have at least 8GB of RAM available for each worker (see the installation documentation).
You can also use a SmartName resolving to ResampleFull.
3. If you are proofing files containing a white separation (for example for a white underprint), and your chosen
is connected to an Epson Stylus Pro WT7900 proofer,
you can tweak how to proof the white objects in your file(s) with that proofer's white ink.
For example, you can use this to get a cooler or warmer white when printing on transparent or metallic foil.
To do this, select White Coloring and choose either:
• No Coloring if you just want to print the white objects using the proofer's white ink, without tweaking the white ink's color.
• Custom Values if you want to tweak the color of the proofer's white ink manually.
In this case, click Set Custom Values... and enter the CMYK values to add to the white ink.
• Values From Color Management if you want to use the color strategy you defined in
to tweak the proofer's white ink.
55

Pack Proof
Note:
This color strategy must have a white Extra Output Ink (called white) and map the white separation in your file(s) to this white output ink.
Color Managing your Proofer's White Ink
on page 56 for information about how to
create such a color strategy in the Color Engine Pilot.
You can also use a SmartName resolving to NoColoring, CustomValues or
FromColorManagement.
4. Enter the number of Copies you want to print (at least 1).
You can use SmartNames and/or public parameters.
Tip:
If the number of copies to print is already defined in your
number will be filled in by default.
You can of course change it as desired.
5. Select Keep job files for relaunch purposes if you want to be able to proof jobs a second time without having to RIP them again.
In this case, the files created for proofing will not be automatically cleaned up. When you don't need to keep them anymore, you will have to delete them manually from the \\[Esko
Proof Server]\ProofFolder share.
You can set this option with a SmartName resolving to true to keep the files, or false to discard them.
Note:
To re-proof files that you have kept using this option, do the following:
1. Double-click the Send to Proof Server sub-task that was run on the job you want to reuse.
2. This reopens the ticket with a limited number of settings. Change your desired setting as necessary (for example the number of Copies).
3. Click Launch.
If you didn't select the Keep job files for relaunch purposes, you will see The job cannot be reprinted as the files from the job were not kept when reopening the ticket.
4.7.1 Color Managing your Proofer's White Ink
If:
• you are proofing files containing a white separation (for example for a white underprint),
is connected to an Epson Stylus Pro WT7900 proofer,
... you can color manage your proofer's white ink using a color strategy, for example to get a cooler or warmer white on your substrate.
56
Pack Proof
To do this, open the Color Engine Pilot and do the following:
1. Add the following inks to the designer ink book:
• the white separation used in the file you want to proof (for example cool white),
• a generic white separation, that must be called white.
2. Create a color strategy that will color manage your file’s white ink: a) Add your generic white ink as an Extra Output Ink in your color strategy.
b) Map your file’s white ink (cool white) to your generic white output ink.
4
c) Make sure that Ink Mapping... and Extra Output Inks... are selected in your main color strategy dialog.
Tip: If you need more details to perform these steps, please see the
Color Engine Pilot documentation
