QTR-Quadtone RIP

Thanks again, Tom.

I tried converted a file to QTR-RGB-matte profile in Qimage and then 
opened it up in PS.  It is indeed converted to an RGB file with the 
above profile embedded.  

I haven't used Create ICC with QTR yet, so I don't know how it fits 
into the scheme.  

Regards, Lou

using Gray-Lab as the working space if doing an RGB image it will be 
Adobe RGB.  Then when I'm ready to print to file in Qimage I'll use 
rgb-matte.icc as the printer icc in Qimage.  I'll also save 
resampling and final sharpening for Qimage as I think it does a 
better job than just about anything else.  Interpolation is Pyramid 
and the Smart Sharpen setting is at the default or lower depending 
the image.  It would be nice to have a preview on that.

I've been forced to use Photoshop for printing.
