QTR-Quadtone RIP

Sorry no idea how to do that. However I am very interested in your 
profile for the R800. I did one myself using Black and Photo Black 
but I am not totally conviced (especially when using semimatte 
papers). Any chance that you uploaded your profile to test it? Waht 
papers are you using?

Regards,

Ignacio
