Digital BW, The Print

Nick,

I don't have black banding problems on my 1280 or 2200 when used with 
OPM. However, in recent testing I have found that OPM likes 720 dpi files 
best, preferably in 16bit. Have you given that a try? For the purposes of 
testing, you can just try to res up an existing file in Photoshop, using bicubic 
interpolation. 

I am guessing you already did whatever it takes to clean the heads, including 
under the carriage, and have tested for different positions of the head lever. 
IOW, I assume you've done everything to eliminate any actual hardware / ink 
delivery problems, and have narrowed the issue to software, right?



On another issue - I am a bit confused in reading your post. You say:

The 1280 does not have 2 black ink carts (or shouldn't). You may have meant 
something else?...


Regarding 1280 vs 2200, depending on what inkset you load, the 2200 will 
have a technological advantage (speed among others as you noted), but the 
1280 is capable of very fine results. I use mine with Selenium Piezotones and 
- once properly profiled - love the results.  The problems I used to have were 
related to the canned profiles that came with the old piezo export plug-in 
which produced simply ridiculous prints. IJC took care of all that very quickly!
