QTR-Quadtone RIP

I am new to NK7 ink. I am using an Epson R1800 w/ QuadtoneRIP on Mac  
OSX.  The results on matte paper are good, however the same  
monochrome image printed on Epson Premium Glossy photo paper results  
in good looking prints but the top layer of ink never dries. I am  
generally printing at 2880 dpi and I have not changed the ink limit  
adjustment. I select  glossy paper in the "Printer Features" popup.  
Is NK7 ink designed to work with glossy paper? Do I need to reduce  
the amount of ink laid down in the ink limit adjustment? Is there   
some other setting I am missing? Thanks. Scott

The NK7 inkset is designed for matte and fine art papers, not rc based
emulsions at all. Same with all the Piezzotone inks. However, that is
not going to stop me from tying it on the Crane Silver Rag. I don't
expect much but I'll try. There have been reports though of someone
trying K7 in a beta test with a Roland 12 channel printer and the Ergo
Soft Davinci rip to precisely control ink limits. They said the print
tests on Silver Rag "passed the muster", what ever that means. So I
guess it is not totally out of the question. Now the bronzing
situation, they didn't say.

Now the one thing that has occured to me is whether one could
substitue a good PK ink in the darkest slot of K7 to do glossy work.
That would be amazing and produce a really different and innovative
result. But this would destroy all the generic curves that are offered
so would would have to start from the beginning with designing them
for that combination I assume. I have a feeling someone will try that
in the near future. It is an obvious thing to try. But it might also
effect the color neutrality, which is a major reason this inkset was
designed the way it was in the first place. But since the PK would be
the darkest channel and is laying down the max black content, possibly
not visible color change?

If I had another printer and time to devote to that I would. I don't
right now.

Right. Me too. You would need a photo black. It seems to be a paper
made for K3 if your using pigments. I'm not going to mess up the
beauty of the K6 by adding a photo black. Not his year.
