I have recently purchased an Epson P800 and was looking for a paper worthy of this printer. I have tried all the Epson papers, Legacy fiber, Ultra premium luster etc. My favorite so far is 75lb. Arctic Polar Luster. It is bright white with super blacks and great color saturation. Very noticeable difference compared to Epson ultra premium luster. These are my main paper types but I will try the metallics and Mattes soon.
