Is there a curve for K7 QTR for Canson Platine on the Epson R2880? If not, what existing curve can be used?
You can get Piezography K7 glossy curves and information about what printer models can use the same curves, and how to install new curves for use with QTR, here: http://www.inkjetmall.com/tech/content.php?158-Piezography-K7-Additional-Curve-Resource
I recommend using one of the 3880 curves for Canson Platine Fibre Rag paper.
Best regards and happy printing~ Dana
