The printer would then transfer the proof design to a zinc plate under a press, and hand-etch the drawing onto the plate with a stylus. The plate was then rubbed with oil, which would not stick to the repellent coating, but adhere in the etched areas. The printer could then ink the plate, and it would remain in the grooves. As in
