Procedure of creating ICC Profile for the COLORIP Ver.2.x
Revision: 2004.10.4 (The process of Calibration for RCR2.2 has been added.)
Revision: 2004.5.12 (The process of Calibration for RCR2.1 has been corrected and Screen shot has been changed.)
First edition: 2003.10.15
Device to be used
OS: WindowsXP/2000
Application: COLORIP Ver.2.x, GretagMacbeth ProfileMaker Pro 4.1
Spectrophotometer: GretagMacbeth SpectroScan
Notes
Make sure to use RCR Ver.2.1 and above.
* The process of measuring calibration curves is different from RCR Ver.2.0 and below.
The process of setting for Ink Limit is different in case of using [Precision Stochastic Screen] at RCR Ver.2.2 and
above.
This procedure explains in case that [GretagMacbeth ProfileMaker Pro4.1] or [GretagMacbeth SpectroScan] is
used. It is different if other application for creating ICC Profile or other Densitometers. Make sure there might be a
restriction of distributing the created ICC profiles depending on the application used.

Print [CMYKGradation.ps] file and adjust [Limit Control] in
[Halftone Properties] window so that there is no white lines in
the Printing result as shown in Fig.7.

Fig.7 Halftone Properties
** Establish the [Limit control] value for [Digital Mezzotint – Variant B]. **
Following samples are printed on the SPVC-G with Sol Ink LcLm at Standard mode with different [Limit control] value. There
are clearly white lines with each band in each color (especially in the black color). By comparing the 3 samples, you can find that
you should set the value at 40% because the white lines are fairly visible.
Halftone Properties –The value of [limit control]: 90%
Halftone Properties-The value of [limit control]: 60%

* Perform step I and II in case of using Halftone Properties of [Precision Stochastic Screen] at RCR Ver.2.2 or later.

2.
Printout [CheckPureColor.ps]. Check the Red color you
satisfied in this pattern and also check whether the ink is
overflowed or not at C100%M100%Y100%. Set the
correspond Ink Amount individually by the Red color.
Check [Show Color as Percentage] from [Color] menu and
adjust the Ink Amount in Calibration dialog. Click
[Calibration] button at [Color Transforms] in Fig.6 to
display [Calibration] in Fig.8.
* In this example, click [Magenta] in Colorant and drag the
100% point to 80%. And also, click [Yellow] in Colorant
and drag the 100% to 70% in Fig.8.
<TIPS>
Basically, [Color Separation Rule] is not used.
Fig.8 Calibration
It is recommended that you check the ratio by comparing
the result, which is printed each time after changing the Ink limit amount of M100%Y100%.
However, be careful not to set the amount too low. The quality of gradation printing might be affected.
As for the ink overflow, it should be adjusted with [Ink Limit (Total Percentage)] in [Color Transforms] in Fig.6.
<TIPS> How to adjust the maximum amount of each ink
In this example, click [Yellow] in colorant and drag the 100% point to 75%.
First, check [Show color as percentage] in [Color] menu. Then, change from [Light] to [Dot%] in Fig.8. (In case of
unchecking the [Show color as percentage], the display on the graph will be [In-255 Out-255], which means the notation
is [0~225] instead of [0~100], therefore it would be confusable when the set is changed.

Check [Yellow (Blue)] at Colorant.
Drag the Yellow line to set [In-0% Out-75%] in Fig.8.
Printout [CheckPureColor.ps.] again to check the result.

Printout [CheckPureColor.ps]. Check the Red color you satisfied in this pattern and also check whether the ink is
overflowed or not at C100%M100%Y100%. Set the
correspond Ink Amount individually for adjusting the Red
color. Fig.8-1 will be diaplayed by clicking [Halftone
Properties] in Fig.6. Set the quantity consumed of the Ink by
the slide bar at [Ink Reduction] in Fig.8-1.

Printout [CheckPureColor.ps.] again to check the result.
* Click [Calibration] button in Fig.8-1 when you measure the Calibration curves.
Measuring Density Curves
1. Measure output density patching using the Densitometer. In
case that the [Color Mode] is [CMYK] or [CMYKLcLm],
print out spectroscan_4color.ps.
In case that the [Color Mode] is [CMYKOrGr], print out
spectroscan_6color.ps.
2. After density patches are output, go back to the
[Calibration] window in Fig.8.
3. Select a densitometer from [Densitometers] menu as shown
in Fig.9. In this case, select [GreatMacbeth SpectroScan] so
that GratagMacbeth SpectroScan is used.
Fig.9 Calibration – Select the Densitometer
4. Select the port which is connected with the Densitometer
and Click [Calibrate] button in Fig.9-1 to calibrate the Densitometer.
Fig. 9-1
Fig.9-2 Process Test Strips
5. After the calibration is completed, click [Next] to open [Process Test Strips] in Fig.9-2. Here, density patches is measured.
Click [ReadStrips] to measure each color which is checked in Fig.9-2. In case of [CMYKOrGr] mode, 6 buttons will be
displayed.
6. After reading all Density Strips, click [Finish] button.
*If you click [Finish] when ink allocation has been changed at the time of
setting the amount of ink (for example, Y is decreased to 75%), the window
below is displayed. In this case, click [No] to reflect measured density data to
changed ink allocation. (If you click [Yes], information of changed ink
allocation will be deleted.)
Calibration measurement completed
Output the Color Patch
The same procedure is used with any color mode, [CMYK], [CMYKLcLm] and [CMYKOrGr].
1. Output the Color Patch to create the ICC Profile.
Print the [TC3.5 CMYK.tif] and set it to spectrophotometer (Gretag SpectroScan).
Note: Scale it up to 130% with RCR when output the Color Patch in order to read it with a densitometer stably.
Read the Color Patch
Finish the COLORIP because the computer cannot communicate with the photometer if the COLORIP is running.
1. Start the GretagMacbeth ProfileMakerPro.
2. Click the [Printer] tab.
3. Select the [TC3.5 CMYK+Calibration Ref.txt] from Reference.
4. Here, select the [GretagMacbeth SpectroScan] from Sample.
5. The spectrophotometer starts the calibrating itself automatically and then
[Measurement] menu in Fig.10 will appear.
6. Click [Start] to measure.
*The window which is displaying about save will be appeared when it is
completed. It is recommended to save the measured data. Because when you
recreate the ICC profile, you can skip the step, which you measure practically.
Fig.10 Measurement
Create ICC Profile
Setting ICC Profile
1. Set the parameters on the Profile Maker Pro as followings.
Profile Size: Default
Perceptual Rendering: Preserve Gray Plus
Gamut Mapping: LOGO Chroma Plus
Viewing Light Source: D50
Correction optical-brightener: uncheck
And then click [Separation…]
2. Set the parameters as followings. It might be necessary to change the
setup depend on the situation.
Predefined: Inkjet400
Separation: GCR3
Black: 100%
Black Start: 40% IPoint
Balance Black Point: Click [Balance] and balance CMYK.
Black Width: 100

In case of brimming the ink even if you set [Ink Limit (Total
Percentage)] on Color Transforms dialog, it will be improved
slightly by reducing the value of the [CMYK Max] (It is
recommended that the value is above 260%)
If you set the [Black Start] 40% at GCR, gray part, which is
0%~40%, will be printed by composite only. And it will be less
grainy.
3. Click [Start] to create the ICC Profile.
Fit the created ICC Profile in the Image Configuration
1. Select [Browse] by clicking [Select] button
at ICC Output Profile.
2. [Select an ICM file] dialog is appeared.
Select the created ICC Profile and click
[OK] button.
3. Confirm that [none] changes to the selected
ICC Profile name.
4. Check [Use Embedded ICC Profiles (when
present)].
5. Click [OK] button

6. Click [OK] button to close [Image Configurations] window.
7. [Image Configuration—Save As] window is appeared. Click [OK] and overwrite it. After that, click [OK] button to close
[Image Configuration] window.
Creating ICC Profile and Setting Imaging Configuration has been completed.
Using the imaging configuration, output test data for profile checks to check the quality.
* If problems such as ink overflow are arisen, change the set value of [Ink Limit (Total Percent) on the [Color Transforms]
window to make fine adjustment. However, if you have changed the set value, be sure to check the printing result
because if you decrease the set value too low, print can fade.
