Today’s news is to highlight the different impression levers (what sets paper to touch inked form) on two models of Heidelberg Windmills. Our general workhorse for letterpressing invitation sets is the 10 x 15 windmill, with it’s solid bar capped by a red ball. The hulking cousin to this press is the 12 x 18 model with wider feed tables and more of a yoke for putting a firm handshake into to get it on impression. Can you see the family resemblance with their yellow eyes? How sweet!
