QTR-Quadtone RIP

Thank you for that information.  It helps ease my mind somewhat.

In fact, I am referring to "Ultra Premium Presentation Matte" paper.  It looks like you are getting a Dm of 1.57 on that paper.  I have H. Museum Etching as well.  Haven't printed out a calibration ramp on that paper yet.

I find it interesting that the Epson paper loads up so quickly.  It reaches nearly 1.5 somewhere around 50% load and VERY gradually gets to Dmax.  Whereas it seems clear that the other papers are increasing in density right up to 100% load.  Well, maybe not that interesting.  It's why we need to profile the papers, afterall.  Right?

After doing a few more prints since my original post I think I agree with you.  The blacks aren't that bad on Epson matte.  I think it was my initial impression of my first print in going from the dye/pigment inks of my R1800 to pure pigment inks on matte.

Plus the print I made was not really processed optimally and was lacking in contrast.  The result was a print that seemed a little dull and life-less without any black punch.  My subsequent prints have looked pretty good.

Thanks again.

Mike
