You are so out of date it is funny. No wonder Kodak went to the wall. I have been out of the industry for going on 18 years... I see Kodak has a spot color mixing solution, I don't know when this came out ... I think mixing might be a better algorithm than matching in some many-colorant systems, just my opinion -- Dale http://www.dalekelly.org |

Isaac colorimetry alone would get you to "good enough color", accurate enough too edit from Under very controlled lighting, true. Isaac |
