Profiling a Media with Roland VersaWorks
This document describes the procedure for creating media profiles in VersaWorks. VersaWorks provides
profiling functions such as density linearization (or calibration), ink limiting and print mode customization
through Media Explorer window. ICC profiles must be created with a third party profiling application. In this
document, X-Rite ProfileMaker Pro 5.0 and i1Profiler are used as a reference.

Preparing Your System
Media profile reflects the state of your entire system and the conditions of your printing environment. A good
quality profile can only be created when your entire system is properly calibrated and operating within the
specifications. Please follow the recommendations described in the following section for preparing your
system for profiling.

Creating Profiles with VersaWorks
Preparing the Printer and Pre-Testing the Media
Before starting any profiling work, make sure the printer is operating at its optimal conditions:
Printer is set to [FULL WIDTH SCAN].
Tech Tip: For VersaUV printers, setting the printer to [FULL WIDTH SCAN] is not necessary.
All nozzles are firing properly (no missing or deflected nozzles).
Bidirectional printing alignment is corrected for the media being profiled.
Media feed calibration is adjusted for the media being profiled.
Please consult the printer manual for details on performing the adjustments above.
It is strongly recommended to test the media for compatibility prior to begin profiling. A good starting point is
to test the media with any Generic profiles available in VersaWorks and check whether you can get
acceptable prints on any print mode. It is not necessary to judge color accuracy at this stage but you should
look for issues such as ink bleeding, drying time, saturation of colors and persistent banding not caused by
feed accuracy.
Profiling can compensate for some issues but it will never make an incompatible media with severe printing
problems to work with your printer.
Configuring VersaWorks Preferences
Make sure the spectrophotometer is connected to the computer with VersaWorks and that all required driver
and profiling software are installed and working correctly. Configure VersaWorks for the spectrophotometer in
use as follow:
A. Start VersaWorks and navigate to [Edit] menu and select
Tech Tip: Double clicking on the computer icon will also open the
Preferences window.
B. Select the [Measurement Instrument] tab.
C. In [Hardware Settings (for Media Explorer)], select the
spectrophotometer from the [Model] list.
D. In [Connection], set the communication parameters to match the
device settings if necessary.
E. Click [OK] to close Preferences window.
Creating Profiles with VersaWorks
Configuring VersaWorks Queue Settings
During profiling, VersaWorks sends several jobs to the printer through the Queue A. Although most of printing
parameters are determined by media settings in Media Explorer, some layout and printer control settings are
still dictated by Queue Settings. Set the following options in the [Queue A Properties] window:
A. Navigate to [Edit] menu and select [Queue A Settings].
Tech Tip: Double clicking on the [A] folder icon will also open the [Queue A Properties] window.
B. Select the [Layout] button.
C. Click on [Get Media Width] button to retrieve the media size information from the printer.
D. For some specialty media like heat transfer material, selecting the [Mirror] option is necessary for the
transfer process.
E. Select the [Mark] button.
F. Place a check mark next to [Print Job Properties] and then to [Quality Settings] and [Date/Time].
This is helpful when profiling multiple types of media and print resolutions. This will add annotations to
the charts to make it easy to determine which charts need to be measured later.
G. Select the [Printer Controls] button.
H. On some printers, the heater settings can be controlled from VersaWorks by selecting [Custom
Settings] or [Use Default Media Settings]. Other settings such as [Feed Calibration] and [Vacuum
Power] are determined by media settings in Media Explorer.

Creating a New Media in Media Explorer
Media Explorer manages the list of media profiles available for the current printer and ink configuration. In
order to profile a new media, a media setting for the new media must be created.
Create a new media setting in Media Explorer as
A. Navigate to [Media] menu and select [Media
Explorer] in VersaWorks.
B. Click on [Create New Media -
] button.
C. In the Create New Media window, enter the
name for the new media in [Media Name].
D. Select the media template from the
[Template] list.
E. Click [OK]. The new media is added to the
bottom of the list in Media Explorer.
Tech Tip: The following media templates or a subset of
this list are available for selection:
[Generic Vinyl Template] – Select this template for most of adhesive back vinyl or paper products.
[Generic Vinyl Dry Template] - Select this template when profiles created with Generic Vinyl Template produce prints
with dark banding (dark lines between the passes) or the ink takes too long to dry.
[Generic Vinyl Rich Template] – Select this template when profiles created with Generic Vinyl Template produce prints
that are faded and lacks saturation.
[Generic Banner Template] – Select this template for most of banner products.
[Generic Banner Rich Template] – Select this template when profiles created with Generic Banner Template produce
prints that are faded and lacks saturation.
[Generic Clear Film Template] – Select this template when profiling clear media and/or requires ‘White’ ink.
[Generic Clear Film Dry Template] – Select this template when profiles created with Generic Clear Film Template
produce prints with dark banding (dark lines between the passes) or the ink takes too long to dry.
[******* Template [MT] ] – Select template with [MT] designation when creating profiles that requires Metallic ink.
Configuring the Print Modes
Each media template has a set of recommended print modes that are automatically enabled and listed in the
[Mode List] section of Media Explorer. In general, the recommended mode configuration should work well for
most of media but the configuration can be modified to list only the modes that work well with the media.
Creating Profiles with VersaWorks
Changing the Default Print Mode:
The default print mode is the mode that is automatically selected when the media is selected in Job Settings
or Queue Settings. The mode marked as default such as in [Standard(Default)] is the current default mode.
To change the default print mode, follow the steps provided below.
A. Select the new media in Media Explorer.
B. In [Mode List] section, select the print mode that will be set as the new
default print mode.
C. Click on [Set as Default] button. The new default mode displays with the
“(Default)” suffix.
Enabling and Disabling Print Modes:
Not all available print modes are listed in Mode List by default.
The hidden modes can be enabled if necessary. Similarly,
modes that are unnecessary or do not produce acceptable
results can be disabled to avoid mistakes.
A. With the new media selected in Media Explorer, uncheck
the [Hide Non-recommended Modes] option. All
available modes in media template are listed.
B. Click on the [Eye] ( ) icon to toggle between enabled
and disabled. Modes showing the Eye icon will be
available for printing. The default print mode or modes
that are being used by any jobs or Queue Settings
cannot be disabled.
Tech Tip: Additional information on print modes:
CMYKLcLm(v) or CMYKLcLm – the LcLm suffix indicates that the mode is a 6-color mode using the light-cyan and
light-magenta inks. The (v) suffix means that the mode uses multiple droplet sizes (variable dot) when printing.
Modes without the (v) suffix use a single droplet size (fixed dot).
CMYK – CMYK modes without the (v) suffix are available in modes with symmetric resolutions such as 720x720 dpi,
1080x1080 dpi and 1440x1440 dpi. These modes are special modes for printing screen positives/negatives on
films. [Halftone Options] is available on these modes allowing screening parameters such as the screen angle,
frequency and dot shape to be specified. Check the VersaWorks help for more details.
+PASS, W+PASS or +PASSv2 – these suffixes indicate that these modes use Roland Intelligent Pass Control for
improved print quality.
The [Details] section displays additional information for the print mode selected in the [Mode List] as follow:
[Total Passes] – Displays the number of times the head travels to print a band equivalent to the head size. The
print quality improves as the number of passes increases but the print speed decreases.
[Dot Type] – Displays the dot firing pattern. The appropriate mode is automatically selected for each resolution and
media type.
[Dot Size] – Displays the dot sizes that are used. [SML] means that Small, Medium and Large dots are used.
Creating Profiles with VersaWorks
[Separation] – Displays the printing control method selected for the media. The appropriated method is
automatically selected based on the media type.
[Single Color Limit] - Displays the ink limit for each individual color channel.
[Total Ink Limit] - Displays the combined ink limit of all color channels.
[Printer Profile] - Displays the ICC profile associated with the print mode.
Setting the Printer Control Parameters
[Printer Controls] and [Cut Controls] windows hold the common parameters that apply for all print modes.
To display the [Printer Controls] or [Cut Controls] window, double-click on the media name in Media
Explorer or select the media and click on [Media Characteristics Settings ] button.
Printer Controls
[Overprint] – Enter the number overprints. Overprinting is
the process of overlaying the same image multiple times to
increase the saturation. Absorbent media such as fabric
banner may require overprinting for improved color
[Feed Calibration Controls] – Enter the feed adjustment
value for the media. Calibration values for all models in the
same printer series can be entered by clicking on [Change
Calibration For All Models] button.
[Vacuum Power] – Select the appropriated vacuum setting
for the media. It is recommended to experiment with
different settings. The [Strong] option is typically
appropriated for adhesive back vinyl but it can cause
feeding issues on soft and thin media. Banner tends to work better with [Normal] settings.
[Dry Time] – Enter the interval of time the printer waits before executing the next operation (sheet cut, cutting
or printing of next job).
[Head Height] – Select the appropriated head height for the media in order to avoid head strikes.
[Heater Controls] – Enter the heater settings for the media. Setting the temperature too high can cause the
media to buckle excessively, or the ink drop to dry too fast not giving enough time to spread. By the other
hand, setting the temperature too low can cause bleeding and the output may not dry quickly enough for
immediate handling.
Creating Profiles with VersaWorks
Cut Controls
Options in this window are only available if the printer supports
contour cutting.
[Enable Cutting] – This option must be checked on any media
intended to be cut with the integrated cutter. Cutting operation
will be completely disabled for this media if this option is left
Other parameters such as [Cut Passes], [Speed], [Pressure]
and [Offset] can also be set in this window but they are not
used in general, since these parameters may vary depending
on the state and quality of blade (new or used).
Click [OK] to close Media Settings and return to Media
Profiling the Media
The profiling can be started after the media has been created and configured in Media Explorer. The
following steps must be performed for each print mode:
1. Set the Quality Settings specific for the print mode
2. Print and measure the density calibration target
3. Adjust the calibration curves
4. Print the ink limit chart and determine the ink limit
5. Print the color target
6. Measure the color target and create the ICC profile
7. Associate the ICC profile with the print mode
8. Test the image quality of profile
1. Setting the Quality Settings for the Print Mode
Follow the steps below to start the profiling process.
A. Select the print mode in [Mode List] section of Media
B. Click on [Print Quality Settings -
] button.
Tech Tip: Double clicking the print mode also displays the Quality
Settings window
Creating Profiles with VersaWorks
C. In [Print Quality], adjust the following parameters if
[Direction] – set the default print direction. Setting
[Uni-Direction only] or [Bi-Direction only] locks
the [Direction] option preventing changes in this
option from Job Settings or Queue Settings.
[Head Speed] – set the default head travel speed.
[Feed Speed] – set the default media feed speed.
In general, it is not necessary to change the default
settings unless the print results are not acceptable. As
a general guideline, the print quality improves by
selecting unidirectional printing and by slowing down
the head speed.
2. Printing and Measuring the Density Calibration Chart
A. Select [Print Chart] in Calibration Settings section.
B. Enter the individual ink limit in [Single Color Limit] fields.
C. Click [Print].
D. Click [OK] in the confirmation window. The calibration target is printed. The chart format varies
according to the spectrophotometer selected in VersaWorks Preferences (see Configuring
VersaWorks Preferences). Check for issues such as bleeding, banding or any other quality issues
and go back to step B above if any adjustment in the individual color limit is necessary.

3. Adjusting the Calibration Curves
A. Select [Fine Tune and Apply] in Calibration Settings section.
B. Cycle through the list of ink channels in [Channel].
C. Check for any abnormal spikes or dips in the calibration curve. The values on the vertical axis should
always increase as you move to the next point to the right in the density curve.
D. Adjust manually the curves eliminating any spikes or dips. The adjustment should be limited to the
minimum necessary. Changes that alter greatly the shape of the calibration curves must be avoided.
If a curve requires drastic change, go back to step 2-A to reprint and measure again the calibration
Yellow curve – Before the adjustment.
Yellow curve – After the adjustment.

Black curve – After the adjustment.
4. Setting the Total Ink Limit
A. Select [Print Chart] in Total Ink Limit section.
B. Click [Print].
C. Click [OK] in the confirmation window. The Ink Limit Check Chart is printed.
Tech Tip: If you are profiling a heat transfer media, transfer the image on to an actual substrate for evaluating
the output.
D. Look for issues such as bleeding, ink pooling,
banding, excessive drying time or any other
undesirable printing artifact to determine the
maximum amount of ink that the media can accept
at this print mode.
E. Select [Set Ink Limit].
F. Enter the value determined above in [Total Ink].
Tech Tip: [Total Ink] of less than 160% generally translates into poor print quality. If this is the case, go back to
step 2-A and lower the [Single Color Limit] value to get a [Total Ink] value around 200%.
G. Click [OK] and go back to Media Explorer.
H. Click [OK] in Media Explorer and then click [Yes] to save the changes.

G. Go back to step 1 to profile a new print mode or close Media Explorer and test the profile.
8. Testing and Evaluating Profiles
A color viewing station such as the ones shown here are recommended for proper evaluation of color quality.
Test the profiles by printing a reference image. A good test
file should contain both RGB and CMYK objects; cover a
wide gamut of colors, dark, light images and gradients.
Look for any printing artifacts, neutrality of colors,
sharpness, saturation or any other criteria that suits your
needs in determining the validity of profiles.
See the general guidelines on troubleshooting the most
common issues:
A. Banding in dark areas of the image
Possible solutions: a) increase the heater temperature; b) slow down the print speed (unidirection or
slower head speed); c) lower total ink limit (requires re-profiling); d) lower individual ink limit (requires
re-profiling); e) use a print mode with W+PASS suffix; f) recreate the media using different template
such as [Generic Vinyl Dry Template] if available.
B. Streaking (white banding, density drop, etc)
Possible solutions: a) lower the heater temperature; b) slow down the print speed (unidirection or
slower head speed); c) slow down the feed speed; d) re-profile using a different media template; e)
use a print mode with W+PASS suffix.
C. Gray not neutral
Assuming the color was evaluated under a color viewing station: a) make sure the ICC profile creation
settings are correct (consult the manual of profiling software); b) re-profile from scratch.
D. Grainy image
Possible solutions: a) make sure the bidirectional adjustment is correct; b) try unidirection; c)
graininess may be caused by excessive ink limiting. Try re-profiling with higher ink limits; d) re-profile
using a print mode with W+PASS suffix.
E. Flat looking image or not able to hit certain saturated colors
Possible solutions: a) try re-profiling with higher ink limit values; b) re-profile using slower print modes
(W+PASS) or higher resolution modes.
F. Gradient not smooth
Creating Profiles with VersaWorks
Possible solutions: a) make sure the calibration curves are smooth (adjusting calibration curves
requires re-profiling); b) re-profile from scratch changing slightly the [Single Color Limit].
G. Clipping in shadows or not enough detail in shadows
Possible solutions: a) try different rendering intent (Perceptual for raster images); b) re-profile with
different ink limit settings.
