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.

A device for producing print images of varying lengths in offset printing, said device comprises replaceable, cylindrical format sections with differing cylinder diameters. Each format section includes a support shaft with which the format section forms a single unit. The units are replaceable with one another to change print image length.

A printing press for processing continuous webs has a machine frame and printing cylinders exchangeably mounted in the machine frame. A drive is provided. An inking system is mounted in the machine frame. The drive has a two-row gear wheel having a first toothing and a second toothing, wherein the first toothing has an inch-based division and the second toothing has a metric division. The printing cylinders are driven by the first toothing for printing an inch-based size and the printing cylinders are driven by the second toothing for printing a metric size.

Printing press for processing continuous webs

A device for processing continuous webs has a machine frame and at least one tool arranged on the machine frame for processing the continuous web. A drive device is provided for driving the at least one tool. The drive device is a two-row gear wheel having a first toothing and a second toothing, wherein the first toothing has an inch-based division and the second toothing has a metric division. The at least one tool is driven by the first toothing when processing the continuous web according to an inch-based size and wherein the at least one tool is driven by the second toothing when processing the continuous web according to a metric size.
