The International Color Consortium (ICC) color profiles provided with your
printer driver are identical to the color profiles that the internal PostScript
RIP uses, although the latter converts them to PostScript Color Rendering
Dictionaries internally. To use the ICC profiles outside the internal PostScript
RIP, the application and the driver must be configured correctly for good
results.
● Make sure the ICC profile for the correct printer model, ink type (dye-
based or UV), printing material, and print quality is selected in your
application, and that it is being used to convert RGB or CIELab images
to CMYK.
● Choose the correct rendering intent for your type of job: Perceptual for
photographic type images, Colorimetric for logos and proofing, and
Saturation for computer graphics images.
● Make sure the application is sending device CMYK colors to the printer,
not calibrated color. For instance, when printing from Photoshop 5.x,
select the profile and rendering intent in the CYMK setup, select CMYK
as the output color space, and unselect the Postscript Color
Management check box.
● In the printer driver, make sure that Automatic Black Replacement is
disabled, and that no CMYK emulations are being used.
If all of these conditions are met, the results of using a provided ICC profile
externally or internally will be very similar.
