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

2005-01-29 by Roy Harrington

Steve,

I'd say that what you are seeing is in the ballpark of the differences.

I did a page of dots too:
http://harrington.com/dotscans/dotsdots.html

My 1270 UT2 vs 1160 VM is very similar.   The bottom line is that the VM
ink or the new UT-VM has a much lighter light-gray.   I think most people
would say to the naked eye both are "good enough" but if you get the loupe
out you will see the difference.
