Calibration help needed
2006-05-18 by john
Mac OS 10.4.6; Epson 1160; Photoshop CS; QTR 2.4. Cone warm neutral inks. No trouble with the first step, printing the ink separation test in calibration mode. But I can't figure out what to do next. Roy's instructions say: "Back to the 7500 example. We will use 50%. Edit the descriptor file, Run-Quad-Profile, creating the curve set curve-name. Print out the ink test pattern with this new calibration curve set in preparation for the next step. Is there a descriptor file I should be using? Every attempt to modify the file 1160-fs.txt with CALIBRATION=YES and using the resulting curve in calibration mode results in printing a blank page. (Quad1160 driver takes a while to generate the print file, but when it hands off to the printer the paper just runs through.) (I imagine Run-Quad-Profile is what is now (2.4) called Drop-Quad-Profile.app and an alternative to using Install1160.command). The Calibration.rtfd document shows the second ink test page with additional notation at top "Print with Raw CMYK" but I couldn't find a file with this, so presumably it's the same inkseparation.psd file. I tried interpolating from Tom Moore's Windows tutorial and simply repeated the calibration mode with no curve set but with the tone blend set 70-30, but the values I got: (K=100), C=39(% of K), M=47(% of C etc), Y=45 gave a grey scale like a roller coaster. Any help appreciated!
