I just recently began using Red River Paper products for my fledgling photo greeting card business and I must say that the Polar Matte, The Arctic Polar Luster, The GreenPix Photo Matte,& the Pecos River Gloss all have produced superior results on my Canon Pro-100 printer. The help and support tutorials have been invaluable in setting up my printer and with working with greeting card making software in both Google Picasa and Adobe Elements 12. Thanks again from a very satisfied customer!
