A method for controlling a printing press having a first image cylinder for providing at least a first cylinder first image and a first cylinder second image to a printed material and a second image cylinder for providing at least a second cylinder first image and a second cylinder second image to the printed material. The method includes printing a book having individual pages with the first cylinder first image, first cylinder second image, second cylinder first image and the second cylinder second image and providing a first operational mode to an operator of the printing press. The first operational mode permits the operator to review the pages with the first cylinder first image and the first cylinder second image of the book at the same time and to alter the registration of the first image cylinder providing the first cylinder first image and first cylinder second image. The first operational mode also permits an operator to review the pages with the second cylinder first image and the second cylinder second image at the same time and to alter the registration of the second image cylinder providing the second cylinder first image and second cylinder second image. A different second operational mode is provided to the operator for altering characteristics of the individual pages of the book, such as ink zone control.

Device and method for controlling registration in a printing press

A folder system includes an adjustable-lap folder for folding signatures so-as to define folded signatures, an optical sensor for measuring a presence of the fold&ed signatures, and a controller connected to the rotary blade folder and the optical sensor for determining a lap of the folded signatures. Also provided is a method for folding signatures comprising folding signatures in a folder so as to define folded signatures, and measuring with an optical sensor the edges of the folded signatures so as to determine a lap.
