QTR-Quadtone RIP

I also am interested in making digital negatives for alt processes, and have the Epson R1800.  While I have not yet tried QTR for this purpose, I have tried the Photo Black and Matte Black inks on Agfa Copy Jet film, and found the Matte ink could be just wiped off the film, while the photo black was not removed.  (Test: simply wipe a thumb across the output).  

So even if MK produces a better UV blocker I would be hesitant to use it withour great care.

I have just profiled the film for regular use with CS3, but have yet to look at using it with QTR.

  Thanks Robert,

  I'm somewhat familiar with Ron Reeder's materials ... my understanding is he uses the Matte Ink which has higher UV blocking density but is also "grainier" on transparency film ... so I was hoping someone had used the Photo Black ink with the R800 / R1800 and some colors with QTR to make a good smooth UV negative.

  I think the ink set of the R800 / R1800 is much different from the later 2200, 2400 & 3800 of which much seems to have been posted for QTR.
