  • individual ink drops are ejected from nozzles of printheads and transferred to a substrate, that results in a print image on the substrate.
  • By individual control of a plurality of nozzles so different print images can be created.
  • personalized printed products can be produced and / or small runs of printed products can be produced at low cost due to the saving of the printing forme.
  • register An exact match of a print image on the front and back of a printed substrate printed on both sides is called register (DIN 16500-2).
  • Multi-color printing is called the Passer (DIN 16500-2), when individual print images of different colors are combined exactly to a picture. Also in the context of inkjet printing, appropriate measures must be taken to maintain register and / or register.
  • a printing press wherein the printing press has a first printing unit and a dryer, wherein the first printing unit has a central cylinder with its own, the first central cylinder associated drive motor and at least one, aligned on a cylinder surface of the first central cylinder ink jet print head.
  • Textile printing materials are to be understood in particular as those materials as compiled in DIN 60000 (January 1969).
  • substrates such as paper or metal
  • textile substrates are relatively unstable in their shape.
  • textile fabrics are often more or less extensible, with an expansion in one direction usually resulting in a compression in another, for example orthogonal, direction. For this reason, not only one position of the printing substrate must be correctly set for a register-appropriate printing on textile substrates, but also a stable form of the printing material must be provided at least during the printing process.
  • a rotary printing machine has at least a first printing unit having at least a first central cylinder and wherein textile substrate is glued to a substrate and guided with this over the central cylinder and printed by ink jet printing.

This improves register retention and / or transport behavior and / or reduces slippage.
  • the at least one driver can be arranged at any point of the cylinder jacket surface. The fact that no contact of the printing material with a forme cylinder or a transfer cylinder is necessary, there is no risk of a collision of a driver with such a forming or transfer cylinder.

Such a hazard would arise, for example, if this operator had to approach the cylinder surface to wait for the at least one print head.
  • drivers designed as needles could lead to injuries if they still had to face the print head with the print head parked only in the radial direction and the operator therefore had to grasp these driver needles designed as needles in a corresponding intermediate space around the at least one print head to reach.
