Studio On Fire
Have I mentioned how much I've been getting into Letterpress lately? The original way that print was put to paper, the hot metal typefaces were just supposed to graze the paper and leave the print. A resurgence in the art has given rise to many small printing firms rededicating their presses to heavily indenting the paper, adding textures and a glorious touch of panache to thicker (160 lb) papers. The simplest is to have one color presses, that way the paper only needs one pass through the press, and one die-cut plate for the image. Studio on Fire, based in Minneapolis, does a lot of their work in 4-color pressings, and it turns out phenomenal.
I will add that when admiring letterpress, the studio that prints it might not be the ones who design it. Some of them have in-house designers, others don't, depending on how large the operation is. So viewing these are strictly to look at the paper/press quality. Good design is a bonus :D
