  • METHOD OF COMPENSATING FOR A FAILED PRINT NOZZLE OF AN INKJET PRINTHEAD
    Publication number: 20250083455
    Abstract: A method for compensation for a failed print nozzle of an inkjet printhead for the printing of a printed image onto a print material conveyed in a transport direction, includes printing the printed image with at least two different print droplet volumes, one of which is a maximum print droplet volume. At least one compensation nozzle, i.e. a neighboring nozzle of the failed nozzle, prints compensation droplets with an elevated compensation droplet volume compared to the maximum print droplet volume. A frequency for the creation of compensation droplets is defined, and the compensation nozzle is actuated such that the defined frequency is observed and the successive compensation droplets printed by the compensation nozzle have a defined minimum separation in the transport direction.

  • DIRECT PRINTING METHOD WITH A BASE LAYER
    Publication number: 20140323602
    Abstract: A method and a device for direct printing onto plastic containers, where an intermediate layer is in a first step using a first device applied onto the container to be printed and the container is in a second step using a second device printed in certain areas, and the intermediate layer enters into a bond with the container and the print layer that is insoluble in aqueous solutions having a pH value between 3 and 10, and is very soluble in aqueous solutions having a pH value in a range less than 3 and/or greater than 10; and a recycling method for a plastic container having an intermediate layer applied.

  • PRINTING METHOD AND OFFSET PRINTING UNIT
    Publication number: 20120297999
    Abstract: A printing method in a printing press includes zonally metering a printing ink at a first viscosity with a metering device and transferring the printing ink at a second viscosity with a printing form cylinder, in which the second viscosity is greater than the first viscosity. An offset printing unit for implementing the method is also provided.

  • Procedure and device for adjusting gloss in print material
    Patent number: 6950615
    Abstract: To regulate the gloss on a print material, and avoid excess release oil, the properties of the fusing medium are measured, and the gloss on the print material is determined on the basis of the measured properties of the fusing medium.
