RE: [Digital BW] QTR and Gloss Optimizer -- some lateral thinking

2004-11-30 by Nunan, Mike

Hi Steve,

Thanks for drawing attention to that, it's given me an interesting idea. The
method they describe uses the "GLOP" in a different way to Epson's intentions.
As you say, it's doing an overspray, hence the recommendation to use a white
(or nearly completely white) file for a second run on top of the original
print. What first occurred to me was that there is no reason why the original
print needs to be produced on the R800. What's to stop you from coating, say,
an A4 2200 print in this way? Furthermore, why use an R800 for the coating?
Couldn't you use a C84 for this? I would be similar to doing an overspray with
Premier ArtShield or Krylon, but guaranteed to be even.

This suggests it is an "overspray" ie it is applied evenly to the entire image
(or even page) rather than a filler dependent on the deposit of other
ink:

Remember also that the R800 can gloss the entire paper - outside the image
area's borders. Note the use of "fit to page" in the instructions above.

I would use either the Cyan or Magenta slot so that (assuming you are using UC
colour inks rather than quads) you still have access to LC, LM and Y for
cooling/toning.  In the 21/2200 UC curves an equal amount of LC and LM are
used to cool the LK.
