I have been ordering the 60 lb. Polar Matte paper for over a year. I design art prints for children & the colors really POP on this stock. I had used Epson matte paper before & there is no comparison. The Red River is superior in quality.
I've also written to Red River's support for product recommendations & even advice about printers. They always respond promptly & actually answer my questions! ...something most online support does not do! Refreshing!
