Hi,
I recently built some profiles for my printer, HP-1220C, using Argyll (http://web.access.net.au/argyll/argyllcms.html). These work very well with Qimage, an 'ICC-aware' printing/interpolation package which runs under wine on linux. Qimage is available from www.ddisoftware.com, including a free demo. Unfortunately, using the profile to print images from Scribus doesn't work nearly so well, producing a strong blue cast. Printing without an ICC profile from both packages produces identical images. The free printer profiles I've found seem to be CMYK, while my profile and printer are RGB; Scribus prints successfully (bad colors) using e.g. the Euroscale-uncoated profile, but Qimage fails with the lcms error "Output profile is operating on wrong colorspace" regardless of CMYK/RGB printer driver -- so I haven't been able to compare results using another profile. I'm using the same input profile (sRGB) and same rendering intent (Perceptual) for both programs, and I've tried with/without black point compensation and UCR. I'm trying to get Corel PhotoPaint for linux to get a third view on my profiles, but it is a big download. I would say that the soft-proof for both programs looks the same (no cast). I'm using the HP open source HP-IJS (foomatic) RGB printer driver, and don't yet see a way to make it work with CMYK. I know that there's a gimp-print driver which takes raw CMYK, however the HP driver with their 'PhotoRet' technology produces much, much better image output. When I use my profile with Scribus and the raw CMYK driver, there's a similar blue cast -- for whatever that's worth :-) So, I'm looking for feedback, and any hints or suggestions on how I might improve this situation so I can use Scribus and my printer. Is the CMYK printer driver a non-issue, and others are able to make Scribus print fine with RGB profiles to RGB printers? Alternatively if this is the likely problem, is it more like a bug that might be solved with a CVS pull or me diving into the code, or is it an unimplemented feature that would take lots more work? Maybe something else? Any thoughts or info appreciated. thanks for reading, rob.
