Abstract

Abstract A printing press with a page cutting control apparatus (11) for controlling cut-off registration in a rotary printing press (10) includes markers (30, 32, 51, 53) for printing reference marks (36) on webs (20, 23) with magnetizable ink having magnetic particles therein, magnetizers (62, 64, 65, 67) for magnetizing the reference marks, sensors (121-124) for magnetically detecting the reference marks, and a controller (140) for changing the web length in response to the detecting.
