MANAGING COLOR IN POSTSCRIPT APPLICATIONS 26 Mixing object types (Advanced color management) If you place multiple RGB objects, mixed non-photographic and photographic, in a file, a single rendering intent may not optimize output for all the objects. In this case, you can have the photographic objects bypass the rendering intent altogether. To accomplish this, separate the object into CMYK data with a pixel-editing application, such as Photoshop, and perform color correction. Save the file as an EPS or TIFF format file, and then import it into the document. You can save the RGB object in TIFF format and assign it an ICC profile and rendering intent when you import it into the document, if your application supports this feature. Using CMYK source profiles You can specify a CMYK source profile and a CMYK processing method for a job (see Color Printing). The CMYK print options affect all CMYK color data sent by the page layout or illustration application, and can also affect RGB data in a page layout application if the Separate RGB/Lab to CMYK Source option is enabled. • If the document contains CMYK objects that were separated for an offset press standard, apply the corresponding CMYK source profile. For example, for objects separated for SWOP, choose SWOP as the CMYK source profile. NOTE: If you print separations to the Color Server and choose to use the Combine Separations feature in conjunction with the Full (Source GCR) or Full (Output GCR) CMYK processing methods, the result may not match that of the same page printed as composite. • If the document contains CMYK objects that were separated according to the color characteristics of a custom ICC profile (not a press standard profile), specify the corresponding profile as the CMYK source profile on the Color Server. For more information about copying CMYK source profiles to the Color Server with Command WorkStation, see Command WorkStation Help.

Mixing object types (Advanced color management)
If you place multiple RGB objects, mixed non-photographic and photographic, in a file, a
single rendering intent may not optimize output for all the objects. In this case, you can have
the photographic objects bypass the rendering intent altogether. To accomplish this, separate
the object into CMYK data with a pixel-editing application, such as Photoshop, and perform
color correction. Save the file as an EPS or TIFF format file, and then import it into the
document.
You can save the RGB object in TIFF format and assign it an ICC profile and rendering
intent when you import it into the document, if your application supports this feature.
Using CMYK source profiles
You can specify a CMYK source profile and a CMYK processing method for a job
(see
Color Printing
). The CMYK print options affect all CMYK color data sent by the page
layout or illustration application, and can also affect RGB data in a page layout application if
the Separate RGB/Lab to CMYK Source option is enabled.
•
If the document contains CMYK objects that were separated for an offset press standard,
apply the corresponding CMYK source profile. For example, for objects separated for
SWOP, choose SWOP as the CMYK source profile.
N
OTE
:
If you print separations to the Color Server and choose to use the Combine Separations
feature in conjunction with the Full (Source GCR) or Full (Output GCR) CMYK processing
methods, the result may not match that of the same page printed as composite.
•
If the document contains CMYK objects that were separated according to the color
characteristics of a custom ICC profile (not a press standard profile), specify the
corresponding profile as the CMYK source profile on the Color Server.
For more information about copying CMYK source profiles to the Color Server with
Command WorkStation, see Command WorkStation Help.
