Digital BW, The Print

BTW while any of the Roark/MIS Carbons methods will give an excellent  
rendering of the "proof of Piezography" test chart on all printers tested, the  
R800, 4000, 7600 and most Epson driver printers that use Ultrachrome inks  do not 
fare well in tonal separation in areas below 90% K. Whereas all the  Carbon 
Quads easily separate 1% incremental values from Dmin to  
Dmax................without mentioning potential metamerism and color shifts  over time. It just 
depends on your market and the convenience factor. For many a  reasonable neutral 
print from vanilla Epson drivers, canned profiles, and UC  inks, is just 
fine, but probably not for this group.

The separation issue is not one that is usually mentioned when folks ask about the comparison of the Epson drivers/profiles to the althernate processes/RIP's.  Good point.  One that should be pointed out more often.

This is retitled from another thread.

I have noticed this in trying to get UT7 inks to print properly with 
QTR on a 2200 and 7600. I thought that the problem was my 
linearization, not the device.

I had good experience on the 7600 reducing the ink limits and not using 
the BOOST function, but I still have problems with the zone between 
95-100% just going totally dense black. Very ugly transition.

Has anyone else experienced this or have any solutions?
