Abstract

The invention relates to a method for diagnosing the printing process. In particular, the invention relates to ascertaining a need for maintenance of the rollers, wherein the need for maintenance of the rollers is ascertained on the basis of the cross-directional profile of tension of the web in the machine direction measured from the web. The invention also relates to a method for aligning the web of a web printing process in which on at least one roller is installed at least one pressure sensitive sensor on the surface or under the coating of the roller. Preferably, said pressure sensitive sensor measures the location of the edge of the web, preferably from both ends independently.
