In need of help finding the correct canvas paper for my Epson P900. I was looking at the Epson Exhibition Canvas Satin, but a printer sales person told me the thickness, 23 ml, was going to prove a bit difficult with the roll feeder. Have any of you had issues like that? If not on the P900 what about the P800? One of the alternatives I'm looking at is Premier Imaging - Generations Bright Satin Museum Grad Canvas, because it is only 19ml. The canvas will be 17" wide and is going to be stretched. Any thoughts or suggesting would be appreciated by this newbie!
