Todd, I printed the somersets. Here's the results: They all printed identically, with the same blacks. Not quite as good as Epson archival. If you didn't have a lot of large black areas in your print, they would be quite nice. I don't think these papers are the same as the original. The thicker one is a very nice paper.
