"The drop size is just as important as the light ink"
The fact is that you may not see this kind of smaller droplet size on the
large format printers any time soon ,so it may work ok on small printers,
but extrapolating that to mean it makes sense to do with LF printers isn't
proven. The variable droplet heads on the 7600/9600 are something like 4, 9
, and 21 picoliter. I don't remember the exact figure but it sure isn't
close to 1.5pl. 21 picoliter is Epson 3000 league droplet sizes, not
exactly subtle. The 4000 with its smaller droplet was supposed to be much
faster than the 7600/9600 due to the increased nozzle count, it isn't.
Right, which is why I said the drop size is just as important. 4 pl
4-color is roughly equivalent to the Photo EX at 720 DPI, which by
today's standards really isn't very good (although it's still far
better than the 3000).
"The 2200 has an excellent gamut as it is. I've been able to get
very vivid blues and reds from it already"
This is kind of my point, with the right media and profile the gamut is
already excellent. Even with the Epson archival inks on when I had a
10000CF, using Kodak Instant Dry Glossy paper, ImagePrint 4, and Compass
Profile 2.5.6, I still have a few prints here that have screaming reds from
this combo. So much of it is about the media and profile. The only thing I
personally want from Epson is the printers to get faster. My 2 cents.
That's good to know. Performance is a known issue with Gimp-Print,
and on faster printers it's often a limiting factor.
I've been experimenting with dithering algorithms designed to achieve
better overall dot distribution, not just distribution within a
particular ink. This yields better quality with larger drops (lower
resolutions). Personally, I've found that 720 DPI on the 2200 often
produces *better* output than the higher resolutions.
