QTR-Quadtone RIP

I have tracked down the problem to some incompatibility during printing. For same reason, either in Photoshop CS5 or in Lightroom, the ICC profile generated by QTR-Create-ICC-RGB doesn't do any color transformation if applied during printing.

I was able to circumvent this issue by doing a profile transformation in Photoshop: Open image, convert to QTR ICC profile, assign working space profile (gray gamma 2.2) and print without color management.

To print without color management from Photoshop CS5, do a null transformation. On the print window, select Photoshop manages color, same profile of the file (gray gamma 2.2), relative colorimetric, black point compensation off.

Here is my before and after calibration comparison: http://i.imgur.com/SJobQ.png

Hope this information is useful for someone that stumbles on this same situation.
