Abstract

A printing method using at least one transfer roller, whose roller surface is charged with a coating material, for example a toner. The coating material is directly or indirectly transferred from the transfer roller to a support surface of a transfer element, before being transferred at least partially from the transfer element to a workpiece to be coated. According to this invention, the transfer element has a stretching element which forms the support surface and the support surface is stretched in the direction of the surface by a stretching device. This ensures that this method can also be used to easily coat 3-dimensional surfaces which are curved in space.
