HP PK with glop & gloss differential

2009-03-01 by Randy Rancier

I just printed out a OTR inkseparation page at 100% and I am finding that I'm not getting any perceivable gloss differential using HP PK mixed with glop as a base in the LC position at a 
ratio of 25/75.

I also noticed that in the yellow position, where I have glop only on my Epson 1400, that 
once you get over about 70% that additional glop, at the higher percentages, actually 
reduces gloss.

Looks like using glop as a base, with the HP PK, may be worthwhile to counter the usual 
gloss differential of a dilute HP PK as long as the ink stays in suspension and doesn't clog, 
which I guess only time will tell.

Hopefully this next week I will get a chance to profile this mix with undiluted HP PK in the C 
position and HP PK with glop in the LC position, replacing the cool inks in the UT-14 inkset.
