Digital BW, The Print

I am using the OPM/IJC software on both the 1280 and the 2200 right 
now. So far, I absolutely love what this softwarte has enabled me to 
achieve in my sepia-toned prints, after scares with green-shifiting, 
metameric Lyson Small Gamut dye inks.

I've personally found most of my initial prints to be more impressive 
on the 1280 - either due to smaller dots or due to greater sensitivity 
to detail in subtle transitions in the mid-tones. Perhaps not 
surprising considering there's just two black ink cartridges. However, 
I too am having problems with black banding on my 1280, and it's 
currently down while Joe at Bowhaus tries to remedy it.

For a few prints, the 2200 has produced beautiful comparable prints, 
but these seem to be ones with either very fine grain, or somehow, the 
mid-tone transitions work fine. I love the fact that with the 2200, I 
can control the actual color of the sepia with the light magenta and 
yellow (2 on light magenta, 1 on yellow in the IJC), getting a more 
chocolatey tone than I get with the yellower sepia of the MIS VM sepia 
I use with the MIS FS quadtones on my 1280. I also love the 
comparative speed of the 2200 - 15 minutes to get a 12x15 priont as 
opposed to one hour on the 1280. However, quality of the print is the 
most important thing at the end of the day.

So once the last few bugs - ie the bloody black banding - are ironed 
out of the IJC software for the 1280, it's going to be - hopefully - 
my salvation.

So my question is - who else out there has tried the OPM/IJC software 
on both the 1280 and 2200 and what have been your comparative r
