I am trying to print a 13x19 sheet in my Epson SC-P900. After trying to use the front loader with no luck, I tried loading it in the standard rear loader. This worked and the canvas ran great through the printer. After setting paper properties on the printer and in Photoshop (Paper Type = Canvas Satin) the print is rather light, low contrast. I ran the same print on matte paper (Red River - River Linen) and paper settings (Paper Type = Epson Archival Matte) and the print exposure and contrast is good as expected. This is my first time using the Epson for canvas. Previously, I used an HP x3200 for my canvas. Any ideas on what I am missing?
