So maybe now I understand why so many are getting buckling with the HP Baryte now, whereas I saw none of it with the test roll I had last summer. I think the Baryte preset still has way too much ink. I just did a bunch of calibrations, starting with 100% ink load. When I check the patches with the eye-one, I see that at 100%, L values go down for the first 3 patches (the 3rd is the darkest), whereas the first should be the darkest. Even at 80% (the lowest setting!) the 3rd patch is still the lowest (darkest), and here's the kicker, at 80% the 3rd patch is darker than the 3rd 100% patch. So I think this paper needs very little ink; further proof comes from the darkest color patches, which at 80% are about the same density as the 100% patch, but have significantly higher A and B values (saturation).
Meanwhile, I can't find the Baryte preset on the @#$&^%!!! HP website. These people are just so clueless!
Can anyone share with me a new HP Baryte preset, or the download link? Has any one seen this with HP Baryte or any other papers?
Hmmmm . . . just went to look up what the ink limits were for the Fine Art Pearl (less ink) preset on HP's site. That's when I saw that the HP Barite paper had been added to the bottom of the chart.
The page still lists an August 2007 date at the bottom and November 2007 date at the top, even though the paper came out much more recently than either. I'm not sure when they sneaked it in, but I take back my complaint about that documentation, HP.
As for the ink limits, HP seems to measure them differently than Hahnemuhle. I'm not sure what the measure is for Hahnemuhle, but HP says that theirs is rated as picoliters per 1/600" x 1/600" area. For their scale, they show both the Barite and the Pearl (less ink) at a relatively low ink load of 32. Fine Art Paper >250gsm's preset gets a whopping ink limit of 60 by comparison. I may try the Pearl (more ink) preset, which has an ink limit of 42, for another test with the Hahnemuhle paper to see what happens. I'm sure that it would not work with the HP Barite, as it has has buckling problems for me at a limit of only 32, but the Hahnemuhle PR Baryta is appreciably thicker than HP's version.
