Hmmm. According to the (rather old) HP document I have, both HP's Fine Art Barite preset and the Pearl (less ink) are identical: Gloss enhancer, high carriage setting, photo black, ink limit of 32, rendering resolution of 600, printing resolution of 1200x1200, and 16 pass bidirectional printing mode. My APS profiles for the HP and Hahnemuhle papers were both made when the papers were released and this information was current. I know that HP did some tinkering to some of the paper presets a year ago and they may have changed, but I don't have any more recent documentation than the document released in August of 2007. I'd be delighted to have something more recent, if you know of something. I would be rather surprised if HP raised the ink limit with the Satin Barite preset, though, as they have issues with coclking on their paper (whereas Hahnemuhle does not). What information do you have about these? Also, if you are having banding problems, why would you not want to be printing with the 16 pass mode, just to be safe?
