I make CMYKOG profiles with i1publish. One problem that cropped up early on was that some profiles showed up on the list in Photoshop and some didn't. It doesn't matter a great deal, except that in order to troubleshoot other problems, like O and G channel contents based on profiler settings, I needed to be able to convert to them and inspect channel contents. After a lot of messing around it turned out the Mas OS will not register profiles over a certain size and make them available to apps, this remains the case. So my build settings that effect size make the difference.. two questions- What drawback can there be to making the smallest A to B tables? I can't soft proof with these profiles anyway. What drawback can there be to excluding cxf data in the profile? I have all data relevant to the build saved elsewhere. Thanks, Tyler
