Definitions

  • the invention relates to a printing unit according to the preamble of claim 1.
  • Non-impact printing processes are printing processes that do not require a fixed, physically unchangeable printing form. Such printing processes can produce different print images in each printing process. Examples of non-impact printing processes are ionographic processes, magnetographic processes, thermographic processes, electrophotography, laser printing and in particular inkjet printing processes or inkjet printing processes. Such printing methods usually have at least one imaging device, for example at least one printhead.
  • such a printhead is designed, for example, as an inkjet printhead and has at least one and preferably a plurality of nozzles, by means of which at least one printing fluid, for example in the form of ink drops, can be transferred to a printing material in a targeted manner.
  • the printing material should be as constant as possible from the image-forming device, on the one hand, in order to be able to coordinate the image generation in time and, on the other hand, to avoid damage to the image-forming device.
  • the printing material deforms, for example waves.
  • waves can, on the one hand, harbor the risk of damage to both printheads and the printing material and, on the other hand, can lead to poor print quality, for example because of differences long flight times of drops of pressurized fluid.

  • the guide elements can easily be reinstalled or fixed and used further when their surface sections that come into contact with the printing material are rotated by a certain, for example predetermined angle.
  • a very small deflection angle there is a particularly large number of possible renewed uses of the web guiding elements. Due to the large number of web guide elements and the small deflection angle, only low frictional forces and therefore little wear of the guide elements occur. Overall, a very long service life is achieved before wear-related guide elements would have to be replaced.

  • the printing unit is preferably distinguished in that the transport path provided for printing material along the printing section is curved only in one direction, in particular downwards.
