What are OPM and IJC?  Where do you get them? What do they cost? What
printers will they work on? Mac or PC?

I assume that they're some kind of rip software for epsons.

Thanks

Hi Antonis,

I took your advice about rezzing up a file to 720 dpi and changing to 
16 bits and I got MUCH better results with OPM, at least for 1 
particular image with lots of thin strong diagonals. There had been 
noticeable (but fine) stairsteps when the file was 300 dpi and 8 
bits. The same file printed with Roy's QuadToneRIP under OSX didn't 
have the stairstep problems though - maybe his driver can rez up the 
file like the Epson driver.

I think both programs/drivers have alot of potential. I haven't 
purchased Inkjet Control (yet) but the fact that their software lets 
you tweak every ink channel is very nice. With QuadToneRip, you tweak 
4 channels in CMYK mode, regardless of printer model (at least that 
is the case for the 2200 curves). At least with both programs I'm 
seeing no metamerism with the Matte Black ink on EAM and Eclipse 
Satine, whereas the Epson driver always gives me greens and/or 
magentas!

By the way, I have a Mac G4 and am running OPM under OS 9.1. I run 
Roy's QuadToneRIP under OSX 10.4.2.
