Digital BW, The Print

originally posted at photo.net, sorry if somebody catch up with the
duplication.

Hi,

I downloaded qimage's restest-epson.tif file and printed it with a
couple of combinations from qimage itself and photoshop. Printed on
epson premium glossy paper (photo black ink loaded).

The major differences I can see between the prints happens in column
A, first and second rectangles. At a reading distance from the prints
I can tell the following (from best to worst):

1. printed from ps, Best Photo and ABW Neutral. the first rectangle
appears solid dark gray and the second has a very smooth lighter gray
tonality, which still tells about the vertical lines that composes it.

2. printed from ps, Photo RPM and ABW Neutral. the first and second
rectangles look gray again but with some patterns, like smudged.

3. printed from qimage, PremGlsy BstPhoto.icc, res 720, res 720,
Hybrid, sharp OFF. Epson driver set for Best Photo and ABW Neutral. In
this case the first rectangle does not look any more as solid gray,
now it has some sort of strong aliasing, like dark lines on top of a
lighter gray background. The second rectangle is again lighter gray
but there is aliasing as well.

4. printed from qimage, PremGlsy PhotoRPM.icc, res 720, res 720,
Hybrid, sharp OFF. Epson driver set for Photo RPM and ABW Neutral.
very similar result as in point 3 above, but the aliasing patterns are
somehow stronger.

I'm just starting with this printer and I simply want to know what's
the workflow I should adopt for printing. So far, it seems that I
should use the settings of point #1 above, however, in some other
thread I read that Photo RPM is supposed to be the setting that should
render best quality, but I'm seeing that for me Best Photo works better.

I cannot understand why is that qimage gives me a lower quality for
this image. Perhaps my procedure is wrong.

Sorry for the long posting, I hope somebody can enlighten me with some
comments on these results.

thanks, Rodrigo
