The HP Artist software libraries required six items to perform its calculations; a raw (not color balanced, de-mosaiced, linear TRC) image of the artwork, a similar raw image of a white card filling the same field of view with the same lighting, 50+ spectral measurements of the artwork, 10+ spectral measurements of the white card, spectral measurement of the light source, spectral response curves for the camera. With this information HP Artist calculates and produces an ICC profile tuned for that artwork which can be sent to any printer.
What makes me curious is how you get a good pigment patch to measure on an art work, not to mention 50+ patches. The total approach is sound I think. More sound than a 800+ pigment patches color chart that should be universal usable for all art reproductions. -- Met vriendelijke groeten, Ernst Dinkla Gallery Canvas Wrap Actions | Dinkla Grafische Techniek | | www.pigment-print.com | | ( unvollendet ) |
