‘Color Correction’ Tab (PDF–PDF)
ICC PROFILES
To use ICC profiles for color matching, enable this option, then click
the ICC PARAMETERS button. This opens a dialog for specifying the
profiles characterizing the input and output color space.
No color correction on grayscale objects
If this option is enabled, the color correction will not be applied to PDF
page elements defined in grayscales. Grayscale elements will not be
changed in color.
No color correction on RGB objects
If this option is enabled, the color correction will not be applied to PDF
page elements defined in RGB colors. RGB elements will not be
changed in color.
Spot color correction via *.SCG file
If this option is enabled
Spot colors will be corrected independently of CMYK process colors.
This is done by a separate color table, a so-called spot color correction
file (*.SCG). SCG files can be created with ORIS Color Tuner.
The CMYK values defined in SCG files have been calculated from the
device-independent Lab values and the data characterizing the output
device (e.g. ICC profile).
If this option is disabled
Spot colors will be corrected using the specified ORIS COLOR TABLE or
ICC PROFILES. This means the same color table or ICC profiles are used
for correcting spot colors and CMYK process colors.
In this case the colors to be corrected are the CMYK equivalence values
defined in the document itself, or – if not defined there – the CMYK values
defined in the ORIS spot color libraries (*.OSC) in the installation
path …\Program Files\CGS\Common Files\CC. If no CMYK equivalence
values can be found for a spot color, it will be printed in a green tone. A
different shade of green is used for every spot color.
Color correct images only
If this option is enabled, the color correction will only be applied to CT
images. Tints, gradients, text and linework elements will not be modified.
