Abstract

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.
