Digital BW, The Print

Hi Keith,

Thanks for the tip.  It seems to have fixed itself (hooray!)- I did
another nozzle clean even though I had a good test and it went away. 
It was evenly spread across the print so it probably wasn't the belt,
but it's good to know about that.

Did you see my "good news" post about the paper?  That little tidbit
of inspiration hit me about 1:00 am last night.  Paul's wedge was
perfect, I could immediately see what was happening.  I like to trim
the top off to just inside the border.  You can then put one gray
scale over the bottom edge of another, slant them almost flat to the
eye to eliminate the paper edge shadow, and you can really see the
slightest differences.  By sliding the top one sideways back and forth
with the thumbs you can find the points where the two scales match -
they merge and you can't tell them apart.  Because it's calibrated I
could see the difference in the papers' % points where the drop offs
began (in this case about a 2% difference at both ends) and
transferred the values directly to the curve grid.  Nailed it the
first time.  I found that the wedge also makes it real easy to compare
custom dot gain curves and see the differences.  Very nice tool, many
thanks to Paul for that one!

Happy days are here again <ggg>.

Regards,
Clayton
