Hi
Peter,
Profile can be preserved in PS.
Try
simple test.
Open
PDF file in acrobat 6 with image which has ICC profile assigned to it and
save it as PS.
Distill it to PDF and you will have PDF which has again ICC
profile.
So
profile was preserved during PDF to PS to PDF conversion.
It's
possible to save ICC profile in PS as CIEBasedDEFG color space for
CMYK
CIEBasedABC for RGB and CIEBasedA for Gray ICC
profiles.
Some
basic information about how it's done can be found in ICC
specs.
For
example in ICC specs 4.2.0.0 it's page 71.
In the previous version of
ICC specs (ICC:1. 1998-09) it was done differently
See ICC specs ICC:1. 1998-09 from the page
86.
Thanks,
Stan.

Hi List members
I am in the process of setting up printing from application to a RIP over
our network. I wrote to the RIP company about a problem I was having regarding
print jobs losing their embedded profiles when printing from Photoshop's
print-with-Preview to their RIP. Only if I manually configure the assumed
input profiles in the RIP to match the colorspace of the print jobs I am
sending will the job print correctly.
I got the following response to my query.
<quote>
Embedded profiles aren't recognized when printing from applications. When
the postscript file is written from the application and sent to the RIP, data
regarding profile tags doesn't carry through. So, when printing from
applications, you need to be sure that your [assumed] input profile in [the
RIP] matches the color space your file is actually in.
<end quote>
Is this true? From other posts in this list I thought profile information
could be sent in a postscript stream?
Regards
Peter Miles
