I recently opened a fineart reproduction studio. using a cruse scanner, Hp z3200, Cannon ipf9100, Epson 9900 , i1 pro spectrophotometer , and of course a NEC 30’ calibrated screen and the Ergosoft studio print 14 rip software.
The problem is as follow i am having a very bad prints on canvas by bad i mean no sharpness in colors, very Dull Colors and specially a very nonsaturated red color plus a loss in highlights and shadows.
The process is as follows:
i scan on the cruse scanner along with the X rite SG color checker, ( Color management is disabled on the scanner) i do the white balance on the scanner histogram by setting whites to 235,grey to 100, and blacks to 25( average for RGB values).
then i move the target to xrite profile builder , i create a scanner profile using d 50 lighting, then i assign the profile to the scanned painting, convert to adobe RGB using relative colorimetric with Black point compensation and save it.
now for the printer profiles i am creating Halftone or 12C profiles whether on cannon Hp or Epson which i assumed they are multichannel profiles.
i do density linearization, separate ink limit, total ink limit ( 240 most of the times where no bleeding or pooling nor bronzing is available) and finally create an ICC profile with GCR 2 ( black in dark tones) and print around 1000 patches and measure them on the i1 pro.
generate profile and save it.
i am printing the image on canvas Breathing color and Innova matte canvas and i am getting a huge shift in the colors and loss of highlights and shadows.
the profiles seem to work perfectly with photo images or downloaded images. but never from a scanned image.
Today i created an RGB profile on Ergosoft and i got an almost perfect result but i didnt understand why?!
i know maybe it is a little advanced question and i was hoping if someone can help clear things up because i think using multichannel profiles and setting density values and total ink limit can be more useful.
