Digital BW, The Print

Thanks Paul.  I have a 7600 cart of matte black that I am going to use to
fill a 7000 and 1280 black cart (as soon as they arrive from MIS) and then
run them with the Selenium Piezotones in both printers using the piezo,
imageprint and epson drivers.  The problem so far with the Ultrachromes is
that it seems that they only give a good black on EAM...performance is worse
(at least using the epson driver) with any other matte paper.  This is
probably the result, once again, of not having the proper paper settings in
the epson driver.  Perhaps we will be able to get around it with imageprint.
