Digital BW, The Print

Greg,

This is one of the reasons I have two 1280 dedicated to B&W. One with MIS-VM
and the Epson driver and one with FS/Sel-PT with the Piezo driver. I believe
that in the interest of greater sharpness the Piezo driver uses less micro
weave than the Epson driver. As a result it is more susceptible to banding.
At least on the desktop printers.

I actually like the dither of the Epson driver better than any of the others
I have seen. Especially for smooth toned areas such as sky and clouds. On
the other hand with good profiles I have fewer posterization problems with
the Piezo driver.

Bill, I have tried it accidentally. The print was quite good, but too
warm for me.
