In addition to having a whole lot of letterpresses in our print shop, we do have a few offset presses that we use for doing cool things like….flat printing custom envelope liners! We tried letterpress printing them at first, but the solids strained our presses, and with such a large form, we got such a light impression that it looked identical to flat printing anyway….so now we use our letterpresses for things that letterpress is good at (almost everything), and we use our offset presses for things like huge envelope liner solids! After printing the large liners, we send them through a die-cut run on our Heidelberg Cylinder and then hand-insert the finished liners into the envelopes. We fell in love with these bright red liners….
