Re: [Digital BW] UT2 inks and dots in highlights

2005-01-28 by Stephen P. Veillette

Paul,

I'm printing on EEM with the Matte Paper setting (also tried Photo
Paper), both 1440 and 2880 dpi, with the neutral curve.  Also, I'm
using the Eboni black ink-- haven't tried photo black yet.

I'm going to make some scans tonight and post them on the web so you
can see exactly what I'm talking about-- I think a picture in this
case will really be worth a thousand words.

Thank you for your offer for the test strip.  I'll send you my address.

-Steve
