[Gimp-print-devel] ESP 870 results

[Robert L K. <rl...@al...>]

I printed the PDI target full size just now, using a piece of Epson
photo paper rather than the cheap third party stuff I've been using.
It isn't perfect by any means, but overall it blows all of my other
test prints clear out of the water, including some samples I was sent
from an ESC 660 (using gimp-print and Windows).

Settings: adaptive hybrid dithering, 80 brightness, 1.1 saturation,
1.5 density, .9 gamma.  Everything else neutral.

Grain: in pale areas, it's essentially invisible.  That's not the case
in dark midtones; there's still some coarseness there (it appears to
be related to light->dark ink transition).  That seems to be related
to the algorithm somehow; I haven't been able to get rid of it.

There were no problems with pooling of ink or anything.  That must be
a function of paper type.  I guess Epson really does design their
papers and their inks to work well together.  That makes sense.

Overall, it's a bit dark, and there appears to be somewhat of a yellow
or yellow-green cast to it.  The skin tones in particular look very
warm, although not green.  The grays look slightly greenish.  The
paper itself is much warmer than the other papers I've used, but I
don't think that that's the entire story.

The golf balls in the cup look like golf balls, not spheres or
circles.

Epson really has a winner with this printer.  If we can only really
get it tuned...
