Definitions

  • the invention relates to a method for register-accurate double-sided printing of a transparent web or sheet-shaped substrate, wherein the substrate is printed on a first substrate side with a number of n inks and wherein the substrate simultaneously or with a time offset on its second substrate side, which of the first substrate side opposite, is printed with a number of m printing inks.
  • the register is the superimposition of the individual process or printing inks which are applied to a substrate side.
  • the correct position arrangement of the printed image on the front to the printed image on the back is called, although this distinction is not always used consistently in many fonts and the register is often referred to as register.
  • the double-sided printing of transparent substrates to the register at least for specific applications, the same high demands as the passer, so that the printed image of the first substrate side can complement the print image of the second substrate side optimally with high quality impression.
  • the invention is therefore an object of the invention to provide a solution with which transparent Substrates the register deviations can be performed in the same accuracy as the registration errors.
  • the inventive method comprises that at least one benefit on the first substrate side with at least one of the n printing inks at least one register element is printed, said at least one register element as a reference mark for register printing for at least one of the m printing inks, which on one of the first substrate side opposite second Substrate side are applied, is used.
  • n printing inks are applied to the first substrate side and a number of m printing inks are applied to the second substrate side.
  • m and n are natural numbers of equal size one.
  • Such a method has the advantage that the register mark, which is applied with at least one, but preferably explicitly a printing ink of the printed image of the first substrate side and thus at the latest after a setup or Einregel- the passport of the first substrate side completely passerhaltig to the printed image of the first substrate side is visible due to the transparency of the transparent substrate also on the second substrate side and can be detected by means of a detection device such as a camera on the second substrate side.
  • this at least one register mark is used as a reference mark, which is also referred to as the master for the register of at least one or more printed on the second substrate side inks, so agrees the register and thus the register exactly or at least within the control accuracy of the passport to the print image on the first substrate side.
  • the invention has the advantage that thus picture elements of the second substrate side in register with the picture elements of the first substrate side can be printed without using one or more additional register control systems or register control systems.

  • At least one of the register elements is no longer formed as a separate element, but at least one of the register elements is simultaneously used as a registration element of a registration mark for the registration-containing printing of the first substrate side.
  • no separate register elements are printed on the first substrate side, but at least one of the passer elements simultaneously serves as a register element.
  • the register element is arranged more or less symmetrically to the axis of symmetry of the substrate to the registration mark of the first substrate side, so that in the case of the requirement of turning the web for printing the second substrate side, the camera of the detection and control device does not need to be adjusted, which Setup time, setup time and resources saves.

  • a registration element 14a for the first substrate side is printed in each case. Since it is deposited in the detection and control device 8, as the respective registration elements 14 must be designed and aligned, arranged and spaced, the registration marks 13 can be used to control the passport.
  • the registration marks 13 and the associated regulation are usually constructed in such a way that usually one printing ink and thus a registration element, for example the registration element 14a-1 of the first printing ink serves as the master, and the layers and spaces of the other registration elements 14a-2, 14a-3, 14a-4 and thus also the printing inks are aligned to this master serving as a registration element 14a-1, which is why the registration elements 14a-2, 14a-3, 14a-4 are also referred to as slaves.
