When I read the info you posted about profiling 4x6, I got to thinking that one could probably profile CDs/DVDs as well with Print Fix Pro.
Can you describe the procedure for efficiently splitting up the smallest profiling chart?
Have you tried this with an Epson R200/220/R800/R1800?
As I believe is described in the PFP help, 4x6 and 5x7 printers are profiled by simply opening the 225 patch one page TIFF target in Photoshop, and cutting it into quadrants betweeen rows and columns, printing each quadrant on a 4x6 or 5x7 sheet, and after drying, taping the quadrants together from the back to form the full target for reading. All we would be doing in the future is supplying these quadrants precut.
CD printing, unfortunately, is not a very "photo quality" process, but you are not the first person to suggest CD targets. For CDs it would take a minimum of two or three disks to get even the 125 patch target covered. Since there is an innate conflict between a rectalinear array of patches and a round CD with a hole in the middle, my idea is to produce CD blank images that have the patches rotationally around the CD, so that you put the CD into a CD case, and rotate to read patches without moving the spectro, then move in a row, and rotate again. We have not produced such targets yet, but are considering including TIFF format 4x6 and CD targets in the Target folder of a future version.

Thanks so much for the excellent info. I've heard a lot of complaints from people about the quality they are getting when printing CDs/DVDs, so this might be a popular option, especially for the 125 patch target. Of course, if the Dmax and gamut on specific disks with specific printers is low to begin with, then there is only so much a profile can do. I assume this would allow color thermal printers to use the same procedure, but please let me know.
Thanks,
Andrew
