So a common problem under Mac OS10.6+ and PScs4+ is printing an untagged image with no conversion, as needed for a target to be profiled.

The work around being a "null transformation" to overcome the OS converting untagged images to sRGB when asked to print using "no color management". This is done by assigning an RGB profile and then printing using that same profile -- per C.D. Tobie's post & Eric Chang at http://www.luminous-landscape.com/tutorials/solving.shtml

Another issue are (Epson) print drivers that lack an Off (No Color Adjustment) button, and invoke ColorSync when using printer profiles.

Do I understand the problems & challenges with this OS, application & print driver?
