OK. Took some figuring it out but I managed to insert XYZ values into the CIE file for scanin. Thank god to Excel! Got the final profile under control. But, I don't know if I asked for this before, is there a way to visualize the ti3 data in 3D in VRML or under some other utility to see where the datapoints landed in CIE colorspace? I realize this maybe the same question I asked yesterday to which, Graeme, I remember you answered and Kai also added his viewpoints. But this functionality appears very important to me. I need to see how good a sampling of CIE space are my RGB starting point. I compared the Hutcolor target and it is clear to see that with 500 sample points it samples the scanner color space with finer than i1_RGB_Scan_1.4 or any of the IT8.7/x targets. This is where I'm getting at.... Roger Breton
