How can I convert RGB 3-D Photoshop files, created with 3D Combine software, to CMYK for digital printing and still preserve the pure red and cyan necessary for anaglyph 3D print images to work with red/cyan glasses?
I tried converting RGB to CMYK within Photoshop and adjusting the color, but so far, compared to my computer screen, the images on paper are degraded, dark and very ghosty, and the 3D depth is diminished as if the printer just can't synthesize those key colors.
Even after pressuring my professional printer to extensively tweak, detune and calibrate, we still can't get his powerful Xerox digital press to spit out a workable image on paper. It just can't seem to print that true red or cyan.
Do any of you have experience with this issue? Your help would be greatly appreciated as I am working against a deadline.
Thank you very much.
