Abstract
A printing machine () for printing on a substrate having the form of a web () is described. It comprises a web entry unit () for receiving the web () on which a printing process is to be performed and a web exit unit () for dispensing the web () after the printing process. Furthermore, at least two printing units () are provided, wherein each of the printing units () is configured for applying an ink of a predetermined color on the web (). Additionally at least two web paths (A, B) are provided between the web entry unit () and the web exit unit (), each of the web paths (A, B) passing by all of the printing units (). The web paths (A, B) pass the printing units () in a differing sequence. Moreover, a method for changing a color sequence within a printing process is presented. According to this method, the web () is arranged along an alternative web path (A, B) passing by the printing units () in a differing sequence, whereas a travelling direction of the web remains the same.
