Digital BW, The Print

I' ve been doing a bit of testing with GLOP loaded in a (all positions) 
1270 to do an overcoat. The prints are all UT2 prints on a 1280.

I've been using only PGPP and premium semigloss, and prints with 
Paul's curves.

As others have noted, the material is not completely neutral in color. 
The good news is that it seems to neutralize the magenta cast that 
shows up with cold and neutral  toned prints. I don't see any obvious 
color shift when overprinted on sepia or carbon prints.

At less than 10% (maybe even less--my methodology for density is 
somewhat lacking), the overall gloss of the paper is reduced, but the 
differential gloss is eliminated. 

At over about 10-15%, the gloss gets up to and a bit beyond the 
base gloss. 

I believe there is no difference above about 20% to 100%.

Once i have ability to print from my machine with photoshop (up until 
now I've driven the GLOP 1270 with the GIMP, an open source 
alternative that can substitute for photoshop for quad-black printing), 
i will consider printing using the orginal image, so there is a match of 
the GLOP placement to the ink. 

Any word on when MIS  is going to come out with their new GLOP? 
(BTW, it takes about 3 ounces to completely fill the T007 and T009 
carts).
