    • 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.
    • 一种使用至少一个转印辊的印刷方法,其辊表面带有涂料,例如调色剂。 在将至少部分地从传递元件转移到待涂覆的工件之前,涂覆材料直接或间接地从转印辊转印到转印元件的支撑表面上。 根据本发明,转印元件具有形成支撑表面的拉伸元件,并且支撑表面通过拉伸装置在表面的方向上拉伸。 这确保了这种方法也可以用于容易地涂覆在空间中弯曲的三维表面。
