QTR-Quadtone RIP

JH....I have them both and wrote the tutorial on IJC/OPM.  I have 
ImagePrint too.

QTR and IJC/OPM will yield pretty much identical output if they have 
the same profiles.  They use the same gimp dither engine.  

The Windows version of IJC/OPM works great with the 2200.  I can't say 
the same for the 4000 at present, but hopefully they will get that 
straightened out.  

QTR has some nice features for curve building that IJC lacks.  QTR will 
automatically partition the gray inks and get you to a baseline curve 
more quickly.  In that regard, it is a bit more automated.  But, I find 
it a little harder to tweak these curves to get them just right.  IJC 
has a pretty slick interface and the ability to edit curves manually 
with nearly no limitations, which I wish QTR had.  Hopefully that will 
come.  So, I find I have a bit more control with IJC, but it is 
probably more work.  If you have good curves to start with, IJC is 
pretty good, at least with the 2200.

Many people who use QTR with the Epson UC inkset seem to build a cool 
and warm curve, then blend the two for a neutral result.  That works 
quite well.  It is easy to get your pants in a wad about having a 
perfectly neutral gray as measured by a spectrophotometer, but we view 
prints, not numbers.  When I built curves for IJC, I built cool and 
warm curves too, but decided to build a very neutral curve also.  That 
was just my preference.  If you use the Windows version of IJC with a 
2200 and the UC inkset, you can download the curves I built from the 
Files section of this site.  There are quite a few, and they will serve 
as an excellent starting point for future profiles.

QTR has a much larger following and more community support at this 
time, plus there are a lot of people building profiles.  And it is only 
$50, compared to $250 for IJC.  

So, each has pluses and minuses.  Hopefully, the above will help you 
decide.  IMO, either one is a big step up from ImagePrint.  With 
ImagePrint, you are tied to ColorByte's gray profiles, their ink 
limits, their linearization (or lack thereof), etc.  I find IP gives 
decent prints, but they seem harsh in comparison, have poor shadow 
separation, and lack depth and presence.
