TJV: Looks like ColorBase was only available for Stylus R2400 & Pro 4800/7800/9800 and later, not 76/9600. Too bad, it looks like its the ticket for linearization to factory specifications. I have not seen Epson drift over the years to the extent you imply, I would suspect an OS, app, or driver update, or combination of those, the be the problem. Or media manufacture evolution? TJV: I feel the same about the degree of drift I have seen. You can be sure: I have been over and over the setup trying to find the small error that is producing this effect. The OS and version of PS are the same as when I didn't see this effect. The driver updates, well, time just can't be rolled back system move forward. I used to print the same images from both Mac and PC based PS and never saw any difference. I saw Epson as very stable and uniform. I'm with you on this issue, just haven't seen this type of problem. The ColorThink curves are telling you more about what each profile measurement data is reporting about the state of uncorrected output at measurement time than anything else, and differences may even just be between the devices used for each. Without all things being equal, device, software, settings, etc etc, with a before and after profile made identically to compare curves, I'm not sure the curves are helping with your particular issues right now. TJV: I'm hearing you, but I saw the curves made by Atkinson at a presentation. They were much more complex than those shown in ColorThink, but related. They were the real deal. If I'm not misunderstanding, its all about taking the output and correcting it back to a standard, thus the curve represents how much change has to be made to get output back to a standard state. I see that you run an artist quality digital printing service, so you know the issues. Have you ever tried to build a new profile built on a previous version. Seems as if you might have been there. Thanks for your interest and advice, I'm chewing on what you've said. Tim Vitale Paper and Photographs Conservator Oakland, CA 510-594-82877
