Christian,
Hi, I've just started looking into my new companies set up in Onyx
Postershop RIP. The RIP utilises an Onyx default CMYK profile that
when creating a new blank CMYK document in Photoshop with the
working space set to it, then filling entirely with solid black
the CMYK numbers read: 73c 73m 73y 100k not neutral.
Is this a very big concern, how the heck could this profile be
used successfully for so long?
What version of Onyx are you using?
I ask, because OnyxCMYK hasn't been set as a default space in
versions of Onyx for quite awhile now.
For whatever, however, whyever, OnyxCMYK was made back in 2002 and
it's a device profile, not an actual color space--one of the reasons
it's not completely neutral up and down the grey axis. If you dig
into it a little further, it also isn't all that good even of a
device profile. Best thing to do is just toss it out and set your
Onyx CMYK incoming working space defaults to SWOP. Your printer
profile on the media you're using with correct resolution and all,
should of course be your "default printer ICC."
Of course you'll get much more out of that printer if you send it
Adobe 1998 RGB and let Onyx do the conversion to the final print
space. In which case your CMYK working space in Photoshopm and your
incoming CMYK space in Onyx wouldn't really matter.
Regards,
Mike Adams
