Hello Alex,
Do you print Absolute or Relative Colorimetric? It can make a big
difference. In my tests, if I print AbsCol the yellow green cast is more
apparent than if I print RelCol. It is still too yellow green for my taste
in RelCol but it is less severe. I tried tweaking the Media White Point,
which the DTP41UV report is around a = 0.8 and b = -2.6, by making it a =
0.8 but b = + 2.6 in an effort to force some blue in the profile, to cancel
out the effect of yellow. But this was still very far from 'acceptable' to
me. The only trick I have found so far to coerce that printer/ink/media/RIP
combo to go in the direction that I want to is to distort the PO4 target
prior to printing, like Nick Wheeler suggested, making it artificially
yellow. That is giving me some interesting results.
I have sent some of my measurements over a period of 72 hours to HP for
examination by their engineer but I doubt they will be able to do anything
about the inks in this printer for the next foreseeable future. Someone on
the HP forum mentioned something about archival inks (pigments) but I doubt
it will happen.
Alex, I am quite astounded to hear you say you get 'acceptable' results with
PO4/DTP1UV on a HP 10ps because that is exactly the combination I use. For
the sake of comparison, however, I feel compelled to get a pack of that
cheap Kodak Glossy paper you say you get those results on, short of seeing
your prints myself in Brazil -- it isn't like I would not want to go to
Brazil to see it 'first-hand', you know! Rio De Janeiro... The sea ...
Can you please tell me what is the Catalog Number of that Kodak paper?
Muito brigado for the help.
Atenciosamente,
Roger Breton
