QTR-Quadtone RIP

Hi.

I downloaded the trial version of QTR this afternoon and i'm really 
pleased with the neutral greys it enables me to print with my R800, 
using Epson inks on Epson paper. (The only time i got this close was 
after buying a custom profile, but after just a couple of cartridge 
changes, neutral grey was a thing of the past.) I thought all my 
prayers had been answered with QTR.

Having successfully printed some images on Enhanced Matte paper (the 
only paper there are ready-made curves for) i thought i'd try a print 
on Premium Glossy. (Call me old-fashioned, but i like the rich blacks 
that glossy prints provide.) So off i go, only to realise that the 
gloss differential is just too noticeable to be acceptable. Back to 
this message group, and i discover that some people are overprinting 
with MIS glop. I can do that easily enough with my Epson glop. Not 
bad.

Then (at last) i notice the BIG problem -- the ink is smudging really 
badly, with or without the glop overspraying. Back to this message 
group again, and i discover that this is a problem several people 
have encountered, but which nobody seems to have a solution for. It 
seems to come about as a result of the fact that QTR only uses the 
matte black ink, which doesn't sit well on the gloss surface.

So my question is this . . . Is there a solution to the smudging 
problem with Premium Glossy, or do i have no alternative but to use 
matte or fine art papers if i want to print with QTR?

Thanks.
and happy printing
