Has anyone ever tried [with any success] to get Window ICM 2.0 to Color
Manage a CMYK Postscript device?
I have built and placed a CMYK v2 printer profile (PM5/Colorful) in the
color management tab of a Xerox Phaser 7700 and selected ICM Handled
by Host
System in the driver and Graphics rendering (which is the Saturation
Intent
for ICM). Problem is, when I create a postscript file from a PDF file
through the Xerox Driver with the above settings and with all RGB data,
after the file is Distilled with a Leave Color Unchanged setting, the
resulting PDF file is STILL RGB (Pitstop's Imaging Matching Panel) and
when
I look into the Postscript stream, using a text editor, I see the RGB
data.
Why isn't the color conversion taking place?
What application are you printing from? If it's from an application
that generates its own PostScript, in-host color management with ICC
profiles does not occur. It must occur prior to PostScript generation.
If the application is GDI/GDI+ then color management in-host can act on
that stream because it's converted to PostScript by the OS after color
transforms have occurred.
I suspect that if you print from something like Publisher, Word, or
Internet Explorer that the conversion will have occurred. But as you
mention it's a CMYK destination, I'm wondering if in the GDI world
everything is RGB (but then why would it let you select a CMYK
profile), and it would need to be a GDI+ app to do CMYK.
At this point, it won't hurt to try a v4 profile. But, I would like any
suggestions anyone can offer.
I wouldn't recommend it. That's likely to do nothing even if it should
do something because v4 profiles aren't supported by ICM.
