A method for starting up a web-fed printing press is disclosed. In an embodiment, the method includes: a) a first start-up sequence is executed while using predetermined preset parameters that are specific to the printing press and/or the print job for the color register adjustment, cut-off compensator control and the ink density control; b) the web-fed printing press is subsequently stopped, where copies printed during the first start-up sequence are evaluated with respect to the color register, the cut-off compensator and the ink density, and where the preset parameters are adjusted as a function of this evaluation while the printing press is stopped; c) following this, a second start-up sequence is executed, where the preset parameters that are adjusted during the standstill are not used for printing until defined printing press speeds are reached and/or exceeded.

Method for operating a web-fed printing press

A web-fed printing press, in particular a newspaper printing press having at least two printing press subsystems, is disclosed. Each printing press subsystem has a printing unit comprised of several printing mechanisms, a web guidance unit for conveying printed and unprinted substrate webs and a turning bar unit having several turning bars. The printing press subsystems guide the printed substrate webs over at least one shared folding unit. At least one printing press subsystem is designed differently in comparison with the other or each other printing press subsystem such that substrate webs are printable with a different number of print pages in the printing press subsystems.
