Epson RIP vs IJC/OPM

Epson RIP vs IJC/OPM

2003-06-29 by Matthew Born

Hi Antonis,
OK, I see what you're saying about the additional, lighter gray. Makes
sense.  And I'd read a few of the posts mentioning the OPM beta addressing a
dithering issue but had forgotten about that -- thanks, I will send them a
note and give that a try. As I'd mentioned, even with the dithering issue, I
prefer the prints I'm getting with OPM even though I'm using other folks'
curves. I can definitely see the appeal of the full product coupled with a
densitometer. (And an easier route to using other inks, like the
ultratones.)

The primary use of the Epson RIP for me was to output postscript, not B&W
printing. I definitely am leaning towards IJC for that; I just figured I'd
try out the Epson RIP for photos since I already had it. My principle work
is graphic design and I use the 2200 for the odd digital, low run job, like
a industry awards entry or some such thing for clients. The downside of PS
as the rasterizer is speed, particularly if I'm running out a 12 or 20 page
booklet. It can also turn some Pantone colors a little funky enroute to CMYK
or RGB while the Epson RIP actually does a pretty good job with them.
Truthfully, I use an EX and a 3000 for that most of the time anyway since
3rd party inks work very well (for non-photographic uses, anyway) and are
substantially cheaper than OEM for 2200.

Many thanks for your help,
Matthew
