7/5 23:51:53 I have code somewhere to do cmyk to rgb conversions 7/5 23:52:06 It uses tunable tables with linear interpolation. 7/5 23:52:31 It would work like this... 7/5 23:52:52 You take an specific kind of an image in cmyk 7/5 23:52:58 Then you would convert it into an rgb image 7/5 23:53:20 and tune the images color response in photoshop or something 7/5 23:53:29 until you got what you wanted. 7/5 23:53:40 Then you save that ... and that image is then a lookup table. 7/5 23:54:09 It's because storing a 8**4 bytes is a bit too much. 7/5 23:54:27 So it saves a coarser version and interpolates.
