My head's bent a little and I'm hoping the Circle might help me figure out
the best approach to color managing CAD illustrations on SGIs running IRIX.
First, the graphics application folks are using is not ICC savvy (Lectra
Systems' U4ia), and it has users select colors using HSV (I assume identical
to HSB or HSL) values. This space is not defined in an ICC profile
currently anywhere, and no monitor profile is involved either, though they
"recommend a 1.7 gamma." They don't calibrate their displays currently;
they go by what they see on their output, which is calibrated and pretty
damn stable.
Okay, so I would like to define this HSV workspace in an ICC profile for use
as input on RIP stations, as well as to allow me to repurpose them. That
is, to use a profile of their HSV to transform to various outputs.
1) Is it possible to build an ICC workspace profile of HSV? What
information would I need to do this? Can anyone out there perform such a
frightening task? I think it's safe to assume that the HSV values are
calculated from an RGB source, so it's probably an RGB workspace.
2) Am I missing something? Do I really need a profile of the printer and
not the HSV (RGB)? Then maybe I could export the images as HSV (RGB) TIFFs
and separate to the profile of the printer. That would emulate the process
at print time, the results of which they like.
Somebody unbend my head!
