Using Gimp-Print 4.26. and OS 10.2.6, I printed ECI2000 and TC 9.18
targets on an Epson 870. The pages were output out of QuarkXPress 6
with color management disabled (turned off in preferences).
The settings were:
Photo Paper
1440 x 720 (highest quality)
Photograph
Eventone Dither Algorithm
Six Color Photo
Raw CMYK for the ECI2000 and Color for the TC 9.18. Output was
seasoned for several days.
Are you seeing one working better than the other?
I'm concerned because the target printouts are obviously skewed,
and I can generate excellent profiles using the Epson driver. There
are numerous light patches where there is no visible color. Target
charts printed from the Epson driver (with no color management) are
considerably darker.
I'd like to see the target (is it something you can email me as a TIFF
file -- I don't have either Photoshop or Quark, and right now I don't
have a Mac either). I have an 870, and its driver should be
well-tuned. Perhaps there is something we don't have quite right that
I can tune, or I may have some other suggestions.
I'm somewhat surprised that you're seeing light patches with no
visible color; highlights are generally an area where Gimp-Print does
well.
I haven't yet reprinted the targets out of Photoshop (which I trust
-- I'm still experimenting with Quark 6' s output), but my
intention is to optimize them for use (particularly the CMYK) when
printing from Quark.
Any clues before going off into a paper-wasting episode? Assuming
that I can get a usable printout, what is the preferred dither
algorithm -- adaptive hybrid, Eventone, or ???
If you're printing photographs, EvenTone is probably the best choice.
For graphics, Adaptive Hybrid may work better. It has fewer
artifacts, but it's a bit grainier than EvenTone.
