A Pro9000MKII and a MP540. I have changed the ink to the Pro9000 but on the MP540 I use a ink from Image Specialists form some years ago. All the tests are did with the MP540 and with the same ink then I discard any option of ink mixed.OK. > >The visual poblem that I see on my prints are a non neutral ramp of grays, from black to white. I see some grey with magesta cast and other grays with cyan cast.My test patch uses 64 grays. Then I suppose that it mus be prectically neutral on all the ramp.There may be metametrism problem. You should to solve the trouble with profiling fist. Then You will be able to check the prints visual. > >It is possible a error with the color management on my Windows 7 Ultimate or in the printer driver?Yes. It can be the case. If there is some setup for Windows color management, try to set: Global settings: Device profile: sRGB IEC619... WSC profile: for ICC viewing condition Default renderings: Photo Printer settings: Profile: manual Default profile: sRGB IEC619... When You perform this, I hope the OS color management will not change the data between the Photoshop and the printer. In Photoshop: 1. While opening the target from ArgyllCMS assign they sRGB IEC619... 2. While printing, select in Photoshop "Photoshop manages the colors". 3. Select relative colorimetric intent. 4. Disable BPC 5. Select the profile for printer sRGB IEC619... This way You'll be able to use, but "neutralize" the color management behaviour. The color management will be ON and working, but RGB values will be untouched, I hope. I've profiled GDI printers on Vista or 7 such way successfully.
