With StylusRIP setup without any color correction you should be able to get exactly the same color as with the standard driver so if you were getting good neutrality (and only had the postscript text problems) then StylusRIP should be able to match the previous results. However, in some versions of StylusRIP there is a "feature" called "press simulation" and some computer systems (for some very strange reason) cannot access it to turn it off. This impresses a "default" profile on your file and creates a distinct mess. On a Macintosh, the culprit is the use of Adobe PS printer version 8.5.1 which does not work with the current StylusRIP (Adobe PS version 8.3.1 works like a champ). I am not a PC guru so, unfortunately, I can't advise which versions might work. You can download the PC version of Adobe PS interpreter from Adobe's site to see if this will work better with StylusRIP than the built-in PC interpreter (if any??) which sits in front of StylusRIP. You need to find a way of making StylusRIP stop impressing that built-in profile and this is the only way I know how to control it. The problem is that both StylusRIP and the standard driver do not print black with black ink in the medium to light areas. They substitute neutral blends of CMY and, with a messed up profile in the loop, there ain't no such thing as a neutral blend. The Epson technician is right in that there is no way in StylusRIP to adjust color (no sliders etc) but when the channels are coming through untainted you can adjust colors with the application from a CMY file with a pretty fair accuracy. Just be sure to do your mode change to CMYK with the right StylusRIP profile set in Photoshop's CMYK setup (there should be a StylusRIP profile for each paper type and resolution setting). In Photoshop 5 you can apply it in the print dialog box in Space or in the CMYK setup prior to a mode change. If you are starting in RGB or grayscale you can do a mode change using the profile in CMYK setup then adjust the colors in CMYK mode to get a neutral (not the black channel though it may as well not exist as far as StylusRIP is concerned). If that doesn't work, and if, on the PC version of AdobePS, there is a Postscript Color Management (or similar) box in place of the Printer Color Management box, you might try checking that box and in the Options print dialog, select ColorSync color matching and select the Epson profile there. This usually doesn't work as well as doing all the profile applying in Photoshop but it may work with Quark as well as Photoshop since it is a function of AdobePS and not the editing application. I can't say for sure that the PC version has this option but it was at one time the only consistent way you could apply profiles on a Mac. One other thing to check -- In the Photoshop 5 ColorSettings Grayscale Setup, there is an option for "Grayscale Behavior". If you are printing directly from a grayscale file the choice you make here can alter the printed results. Try changing back and forth from "RGB" to "Black" in the ink behavior box. If that doesn't do anything and you are really only looking for grayscale output (not mixed color and grayscale) you can choose "Grayscale" in the Ink options of Stylus RIP. This limits the driver to using *only* black ink so it will not replace black with blends of CMY. This will, however, make the dithering appear more coarse since the black dots in the highlights are more apparent than a mix of CMY dots. If you see a "Black and White" choice don't use it -- it will give you only black and white, no gray. The PC version of StylusRIP seems to be even more quirky than the Mac version (no one has reported success with it to my knowledge) so I think your best bet might be to hold on for a while and wait for Adobe PressReady. Don't know when it will support the 1520 but the 3000 is supposed to be just around the corner. One person on the list suggested using Adobe's Acrobat Exchange which rasterizes your Quark vector files and lets you print through the standard driver. I think the controversy on that thread was that this is an option of last resort (for some reason I don't recall). Dan Culbertson - Please do not include an entire message in your response.
