[Openicc] Wrong color output of Xerox printer - Color Management problem?

[Michael Vrhel]

Gerhard,

There is an open bug to address this 
(http://bugs.ghostscript.com/show_bug.cgi?id=691749).  So few people do CRDs 
these days that it has been a very low priority.   You get the distinction 
of being the first person to notice the issue.   Keeping gs compliant with 
all aspects of the Postscript specification is important.    I will escalate 
this and hopefully it will be fixed prior to the next release.

Michael

Management problem?


I also noticed color issues with the Minolta Magicolor 2300W, which seem to 
be caused by the fact that the new ICC-color-managed gs 9.x does obviously 
no longer support CRDs (CRDs are however a well-defined PostScript 
functionality - i.e. the new gs is no longer fully PostScript L2/L3 
compliant wrt. this functionaily).

Regards,
Gerhard
