Blue Colour Profile Problem
PostPosted: Sun Jan 20, 2013 7:13 pm
I recently purchased a copy of SilverFast 8 ai Studio and a 5x7" IT8 Reflective Target to calibrate my CanoScan 9000F Scanner but i get very different looking colours in the SilverFast preview screen or from the Print Tao Screen than i do from the PhotoShop 5.1 screen or when printed using my Canon Pixma PRO-1 Printer. There is a very significant emphasising of the blues / Blacks - when scanning an image without much blue this is not nearly as noticeable though but still there. I am using a calibrated Apple iMac Screen and a calibrated printer / paper profile both done with an x-Rite Colour Munki Photo colourimeter. See the below Screen shot comparisons...
You might think that the PhotoShop images look better but they are a long way from the more subdued tones of the original... and way to saturated for the finished prints...
The SilverFast IT8 Calibration runs correctly and comes up with a DeltaE of 1.4-1.5 each time and stores the file correctly and PhotoShop finds the embedded ICC profile OK - I have tried 600, 1200, 2400, 3600 and 4800 dpi scans using either the Archive Print workflow or a manual one and saved the files (upto 2400 dpi) in both PSD and Tiff and loaded them into PhotoShop manually - nothing seems to affect the blue / black colour cast or over saturation of the image in PhotoShop whether i leave PhotoShop's working space as the embedded scanner profile or convert to ProPhoto RGB...
The prints match the PhotoShop screen images closely as you'd expect with a fully calibrated workflow but they look nothing like the originals i scanned...
Can you suggest what might be wrong...? I've gone through a whole box of paper and loads of ink trying to find out what is causing this problem...
