QTR-Quadtone RIP

________________________________
I just received the inks for the R1900 with my surpriser there are just two 
black inks and the glossy optimizer. I was under the impression that your need 
at least three channels of Balck in order to have good result. Did I missed 
something? Should I order some more ink to print on Mate only paper?

Thanks,

Flushing is safer, but probably not necessary if you're just replacing the
Epson MK with Eboni MK.

By the way, unless the 1900 is considerably better than the 1800, using just
a single MK channel to print a B&W might result in a print that shows
microbanding.  That is why the "3-MK" system was set up.  See
http://www.paulroark.com/BW-Info/R1800.htm My experiments almost always
guide me back to 3 channels as the minimum for really good printing, and
those would include light ink if smoothness is important.

When there are no light inks in the mix, prints that have very smooth areas
like plain skies will show some graininess.  Even the 1.5 picoliter drop
printers like the 1800, 1900 and 1400 benefit from lighter inks.  I've used
black only in my 1400 with HP PK (neutral photo black) and more recently the
Noritsu-Epson advanced dye, but it really looks good only when the image has
enough detail to hide the defects.  Some of us have also noticed broader
banding with black only.  In short, for top notch printing using a single
black channel is marginal.
