I use double sided matte paper for greeting cards and had been using Epson Double sided matte for a few years. Last year I tried Staples photo supreme double side matte paper that is heavier than the Epson double side matte and prints beautifully on my i960. Much better feel than the Epson paper. I also just picked up a package of Kodak heavy matte paper at Costco that Kodak claims is suitable for printing on both sides. This is a new item at Costco. It does print on both sides nicely, but this paper is too thin for greeting cards or other double sided print jobs. The paper puckers from the wet ink in areas with a heavy ink density due to the fact that it is pretty thin. It would be suitable, however, for single sided CD case inserts or other jobs requiring light matte card stock. The price is really right. I was going to take it back as it was not suitable for my double side printing needs. I kept it, however, for test prints before printing on the Staples paper, and I will also use it for Nozzle tests when the pattern is broken in a very subtle way. I find that plain paper used for the nozzle test has a tendency to have the ink spread slightly in the paper fibers and make the test look better than it really is. I then use a piece of coated paper to get a sharper image of the test pattern.
