I am trying to use color management under gimp 2.4. Despite numerous google searches and posting to the gimp user group forum, I've been unable to find any useful documentation about how to use it. Through trial and error and many hours fumbling around, I've managed to decipher much of it, but I'm still unclear on some points.
How to use the display profile was fairly clear. Profiles for input files was very murky, but I eventually worked out what was happening there. One confusing thing was that if you specify in Preferences>Color Management that gimp Keep the embedded profile, the same thing happens---i.e. no indication---if that profile is the same as the default sRGB profile or if there is no embedded profile, so you can't tell at that point whether or not the source file had one. With some searching I eventually found a couple of other places where that information is provided. I don't suppose it really makes any difference, but it was thoroughly confusing to me. I think I understand generally how to do print simulation, but some points are unclear. Under Preferences>Color management>Print simulation profile I specify a printer profile, and I then choose Mode of operation to be Print simulation. If I check the Mark out of gamut box, then it shows me colors that are not printable. If I don't check that box, I see various colors and I'm assuming that these are roughly the colors as they will be printed. That of course depends on the rendering intent which together with the profile should determine how colors are transformed so that everything ends up in gamut. Have I got that right so far? One thing that confuses me is that I can either choose Color managed display or Print simulation as the Mode of operation, but not both. It doesn't seem to make sense for print simulation to ignore the display profile, but perhaps I am not understanding something. I am completely at sea about how I use the print profile to actually print. Do I set the mode of operation to print simulation and then choose print from the file menu? Or do I put the print profile in the RGB profile slot and then print? Or is this as yet unavailable and dependent upon adding profile capability to gimp print or gutenberg? Finally, I am unclear where else in various gimp menus and tools, color management shows up either in making choices or in providing information. If there is any other useful information about gimp color management that anyone can provide, I would appreciate it. -- Leonard Evens <[EMAIL PROTECTED]> Mathematics Department, Northwestern University _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
