color management use-cases
simple monitor editing is almost trivial, you apply the input profile to
the monitor profile then edit and proceed you can simulate a hard proof, Kodak did it with PCS100, and maybe Prophecy and Design Master, Design Master was Eikonix before Kodak bought it, Kodak bought Eikonix because it had a patent which made scanners with filtration matching XYZ used in Design Master, Prophecy and PCS100 were the Eikonix Kodak people's products, I didn't quite understand that the print reference medium of the above products would have to be made into an option for other media to get these products from the pre-press markets in which they were successful to the commercial photo labs that were interested in color management for multi-purposing of images one way to do a hard proof, you just use the proofer's profile and not the monitor, use the proofer's space as the working space one way if you want to simulate a hard proof on the monitor, you use the "reverse" transform in the profile for the proofer, for instance CMYK-XYZ, then XYZ of the proofer to XYZ of the monitor then the "forward" transform of the monitor's profile, for instance XYZ-RGB, this implies an XYZ working space, but you could pick a device space by XYZ-device a simulation of a press proof works the same way a better hard proof simulation incorporates the press's profile, for instance CMYK of press to XYZ of press to XYZ of proofer to XYZ of the monitor to RGB of the monitor all of the above should happen in the frame buffer of the graphics card above the working space, for instance RGB of proof or simulation of proof to RGB of working space, the working space should be held in memory for editing under the buffer, the edits are made to the simulation in the frame buffer then transferred to the working space and eventually a standard storage space which should be a CIE delta E* space like LAB or LUV for quality and purposing considerations storage is a use-case too I'm wondering if/when CIECAM will enter ICC I'm also wondering if/when ICC and W3C will meet -- Dale |
