A process for a web-fed rotary printing machine and, in particular, a process for pre-inking an inking mechanism. The inking mechanism is cleaned when all other rotating parts of the printing machine are standing still, even with an inserted printing web. Ink residues are removed from the inking mechanism by a washing device, until a defined starting state is reached. The inking mechanism is then newly inked in accordance with subject-specific instructions, i.e., in accordance with a print job to be printed. The inking is performed in parallel fashion during the start-up of the printing machine. Ink application rollers are positioned on a form cylinder when the form cylinder attains a predetermined rotational velocity.
A process for attaining a production-run state for printing an image on a printing web, in a web-fed rotary printing machine with a form cylinder and an inking mechanism having ink zones, the inking mechanism including an ink duct box, an ink duct roller, and a plurality of ink transfer rollers and a plurality of ink application rollers arranged so as to ink the form cylinder by zones in accordance with the image to be printed, comprising the steps of:
