Thanks for your reply.
Have you used any large custom page sizes in AP3? Any thing larger than 17 x 22 (24 x 30 and 24 x 24) has been the problem for me w/ AP2. My color/gamma match has always been reasonably good in AP2, so as long as the print size is no problem, I am good. It's when I go out to PS that colors go haywire.
Actually I haven't tried in AP3 - I have a z3100 and have used photoshop for a few 24 x 30 prints when i was still using ap2
i will need to print a few 24x30's in the next week or so I will let you know but so far size doesn't seem to affect the color
i usually work in photoshop as a final step in my workflow before large prints but with the added tools in ap3 i just might give it a try
