Abstract: A rotary silk screen printing machine or press with a modular design of the individual printing mechanisms and fully integrated control modules within a digital network system of the printing machine is set forth.As a result of the logical, modular design of the individual printing mechanisms, on a given printing machine base with a continuous conveyor belt fixed between two main rollers and which is driven by a main drive motor, it is possible to insert, replace and reprogram individual printing mechanisms. Both during the installation of a new printing system and when reequipping existing systems, considerable technical and economic advantages arise.
