Digital BW, The Print

So, still no definitive answer as to why the 1280 resolution seems poorer?  
 
I pretty much agree on the 2880 situation.  (I'm still trying to figure out why there are 5760 printers showing up.)  I can always see the difference between 1440 and 2880 with a lupe.  And, I can usually see the difference visually, without a lupe.  But, other than some of the canvas I ocassionally print (2880), I believe that the 1440 4pass, and 1440 8pass, is more pleasing than the 2880 prints of the same image.  I'm not sure that the 2880 uses more ink than the 1440 4pass or the 1440 8pass, but I always let the image quality be the determining factor.
 
A question for Paul:  Are there instances with the MIS inks where a 2880 setting produces visually superior prints to 1440?

Hi Tom, 
Thanks for your thoughts. Admittedly, I'm comparing apples to oranges to
some extent: different ink sets and different drivers. But I'm comparing the
two machines at what I consider to be their best B&W-specific arrangement,
not necessarily just an out-of-the-box from Epson comparison. I realize many
consider the pricier rips the way to go, but I am intrigued by IJC's
potential (not to mention OPM's price) and am kind of sitting in that camp
on the 2200 right now. The 2200 was driven by OPM, which does not have user
adjustable output for the dpi. Judging by the speed, though, it's pretty
clearly going at the 1440 setting. The image itself is 720dpi and 16bit.
There are no alignment issues on the 1280 -- I very carefully aligned it,
using a loupe to make the best choices, right before I ran out these prints.
Paul's note with the curves for the UT set say he saw no difference, at
least on EEM, using the 2880 setting on the 1280, and his judgment on that
matter is good enough for me. Besides, even if the additional dpi made up
the difference, the extra time and ink cost (at 2880 vs. 1440) still makes
it a poorer choice. Frankly, I'm leaning towards reversing my setup; using
the postscript software to run the 1280 for my design work, and using the
2200 as my B&W photo printer. One of these days, there'll be empty
cartridges for the 2200 available, and somebody a lot smarter than I will
develop good curves using IJC and an inkset like the UT ones. That would
make a mean B&W machine. Hey, Paul has lots of free time on his hands :)

Cheers,
Matthew Born
