Output Profile Creation
correct the data back to the state of the press when the ICC profile
was created. This window will display what Calibration Set your
output profile belongs to. It also shows the Ink Limit of the Set. If you
have any data in your file above the percentage listed here, it will be
reduced 4 dimensionally to that percentage by EFI’s Ink Reduction
Algorithm. As a reminder, calibration will only operate on one color
plane at a time, so these curves will not result in any pollution of the
primaries.
10. The final option for the data is to choose if you want your black text
and/or line art graphics to overprint any background or knockout. See
page 2-21 for more information on the Black Overprint.
SIMULATION MODE
This workflow has a second path it could possibly take and that is to first
convert the RGB data into the gamut of another digital printer or press
standard and then into the color space of the Kodak Versamark Press on
a given paper. The CMYK data would follow the same path as described
above. This feature is helpful for making one type of output device behave
like different output device.
For this workflow, check the box labeled Simulation underneath the
Rendering Intent drop-down menu. The arrows in the Expert Color
Settings window will update to show the new data path. RGB data will
now be converted to the CMYK Simulation color space first, and then to
the output profile color space you have selected.
Data then follows the same path as described in the first part of this
section.
Output Profile Creation
There are four major steps in creating an Output Profile for your press.
They are:
1 Print the Calibration Pattern and Linearization Page
2 Determine the maximum ink for the paper.
3 Print an ICC Pattern using the results of the Calibration Pattern.
4 Use a utility to create an ICC Profile from the ICC Pattern.
This will go over these three major steps and all the minor steps in
between.
1 Print the Calibration Pattern & Linearization Page
The Calibration Pattern needs to be printed on the press with NO
ICC, NO linearization and NO Calibration adjustment. Once
printed, the Calibrator tool from ColorWise Pro Tools will be used
to read in the data.
1.1 Go to the main CWS window and choose File→ Import → Job.
Navigate to the correct directory. Select the Cal&Lin.pdf file and
click Add then Import (be sure Logical Printer is set to CS600
hold). The job will spool and then drop into a held state on the
server.
