For whatever reason, I can't reply to the original topic... I can think of at least four possibilities (the 3880 is a very standard printer - perhaps THE standard inkjet for photography, and a non 3880-friendly paper would be a major surprise)... One is that you have a bad box of paper - it does happen, not terribly commonly, but it is far from unheard of. The second is that the paper is packed upside-down compared to the papers you are used to, and you're printing on the back of the sheet - don't laugh (I've printed on the back of more sheets of inkjet paper than I care to recall, because it can be hard to tell with many matte papers) - FibaPrint white matte doesn't seem to be a double-sided paper, at least from the specs I could locate. Another possibility would be a lousy profile - I haven't printed on enough Innova papers to know how good or bad theirs tend to be. Some paper manufacturers just don't ship great profiles. Yet another possibility is that your paper type setting is not the same as whatever Innova used when they made the profile. There are at least four or five type settings paper makers use when profiling matte papers on the 3880, and Enhanced Matte is quite different from, say, Velvet Fine Art.
