New IJC/OPM results: Better Dmax, but rougher

2005-06-05 by keithd2010

I've been experimenting with the new IJC/OPM on my 1280 (with UT2 on
EEM).

As suggested by Joe Berndt, I set the ink limits to half what they
were for the profiles from the previous IJC/OPM release.  This gave an
excellent starting point.  Tweaked the ink limits for the black and
dark-grey inks.  Increased dmax by 0.04.  Relinearized.  Results
seemed pretty good.

However...

The new OPM seems to print rougher than the old one.  For all tones
except almost pure black, dots are more visible and smooth tones are
not as smooth.  Edges are not as sharp or well defined.  Seems like
the dither pattern has changed.

I thought at first that it was just that my printer has changed since
I last did a linearization.  But I printed two test strips on the same
piece of paper, once with the old version 1.0.3 and again with the
latest release.  Definite difference.

Has anyone else noticed this?
