A printing press having a conveying path for a paper web formed by rollers and having at least one high-performance printing unit arranged at the conveying path, a plurality of multi-color printing units being arranged along the conveying path at intervals in a row, said multi-color printing units having lower printing speed than the at least one high-performance printing unit;
- and a variable paper web intermediate store being located in the conveying path preceding each multi-color printing unit as viewed in a paper web conveying direction.
A printing press having a conveying path for a paper web formed by rollers and having at least one high-performance printing unit arranged at the conveying path, a plurality of ink jet printing units having a printing rate lower than the at least one high-performance printing unit being arranged along the conveying path at intervals in a row;
- and a paper web intermediate store being located in the conveying path preceding each ink jet printing unit as viewed in a paper web conveying direction.
A method of printing a paper web with at least one high-performance printing unit for printing black-and-white, and a plurality of multi-color printing units, said method comprising conveying the paper web through the high-performance printing unit and then through a plurality of multi-color printing units, changing the path of the web to store portions of the web between each of the multi-color printing units so that the rate of printing in the multi-color printing units is compensated.
