Hello, we have a problem using a special ICC-Profile (http://www.colymp.com/media/download/...) with photoshop CS 5.5. When this profile is used as printing profile (print dialog of photoshop) it is ignored completely (eg. the drop down list of rendering intents below is disabled, and no color transform is done). When the profile is used by main menu>edit > Convert to profile it works fine. In CS 4 (end in good old Photoshop 6) there is/was no problem with the profile above! Is this a bug of photoshop CS5?
Thanks, kind regards

Works fine on this end (Mac OS X 10.7) but this is a goofy profile. The internal naming structure is filled with garbage text:
瀀㐀欀开琀栀椀渀倀爀椀渀琀开渀椀攀搀爀椀最开愀㔀(ᄀ) 愀甀琀漀䰀䈀
Or maybe just a language that is causing some difficulty with your system.

Here is what the ColorSync utility reports:

Tag 'desc': Description tag has a bad Macintosh string.

Even ignoring the description, that profile is horrible -- non-monotonic in several places, rough edges at the gamut boundaries. Yuck. I wouldn't use that except as a torture test of ICC software.

Indeed, the soft proof looked awful. I just wonder if the lengthy string was the cause of the OP’s issues. On Mac, the profile worked albeit it was butt ugly.

Ugly Profile?! perhaps it should be mentioned that the profile was created for a simple copy paper on an old ink jet... If you look at the printout on this printer it's quite useful.
But that's not the topic. The question is why this profile can be used in Photoshop CS4 (both "convert to profile", "printing profile") and in CS5.5 ("convert to profile") but not in CS5.5 as "printing profile". Btw we work with Win7.

Because Photoshop CS5 added more error checking, and finds the bad parts of the profile. CS4 didn't catch as many defective profiles, and those caused problems with color, crashing, or program errors.

This profile is not "ugly", but is rejected by PS_CS5.5 as printing profile too:

Yes, because the whitepoint tag is not within the valid range.

Solved!
It was the _unicode_ part of the "desc" tag (wrong endianess). It's not shown anywhere in Win7/ PS_CS5.5, but PS_CS5.5 cares about it and ignores the profile without any error or warning...

Probably with the wrong endianness it failed to terminate correctly, so parsing the data structure failed, and the profile was marked as invalid.
