The New Hotness

  • HP Super Glossy Paper vs. Generic Ink: FAIL

    When Aitch moved to NC, he unloaded a stack of printer paper on me to avoid paying half a buck a pound to haul it along. One package contained some high-end HP photo paper that, not being a high-end photo kind of guy, I figured I’d use for my 3D printing brag sheets.

    Alas, after trying several permutations of image quality / paper type / ink density, it seems that the cheap generic ink I’m using in the Epson R380 simply isn’t compatible with the HP paper. The top image shows that the ink doesn’t wet the paper and forms a weird alligator-skin pattern:

    The bottom image looks perfectly fine; it’s on cheap Staples photo paper, printed with the usual Photo quality on Photo paper.

    I’ve read vague statements here-and-there that some HP ink uses an entirely different chemistry from the usual inkjet printers and, perhaps, that accounts for the mismatch. Not a problem, but it did blow an hour while proving that it wasn’t the configuration settings doing me in.
