Digital BW, The Print

Hi Michael;

Didn't mean to ignore you, I missed your response-

As you probably have gathered by now, I'm using a second R1800 (which 
I otherwise use for matte printing with MIS K4) The glop is in this 
CIS, though when I get a final setup for the new R1800 it will 
probably include glop as well. For print sizes bigger than 13"-wide, 
I spray the glop with a testor's model-painting airbrush that cost 
all of $20 and does a fine job. I do hate having to do it though.

Yes, QTR, single channel. Carl is having good success with two 
channels, but with the less fragile PK inks I don't think that kind 
of load is needed.

My glop curve is a simple QTR curve with 100% density and a limit of 
50% I print a middle grey field, but sometimes I kick down the Gamma 
slider in QTR a bit. If you get too much on, the shadows come out wet-
 I like to avoid that, and do a second pass if needed.
