Definitions

  • the invention relates to a method having the features of the preamble of claim 1.
  • the invention lies in the technical field of the graphics industry and there in particular in the field of indirect planographic (or inkjet) printing, known as offset printing, onto flat substrates, i.e. the image-wise application and UV curing of printing fluids such as offset ink, varnish or primer (or Ink) on sheet, web, foil or label-shaped printing materials, preferably made of paper, cardboard, cardboard, plastic, metal or composite material.
  • offset printing onto flat substrates, i.e. the image-wise application and UV curing of printing fluids such as offset ink, varnish or primer (or Ink) on sheet, web, foil or label-shaped printing materials, preferably made of paper, cardboard, cardboard, plastic, metal or composite material.
  • the hardening of a printing fluid depends, for example, on the color system used (CMYK or other) or color series (depending on the manufacturer), on the substrate/material, on the radiation source (condition/age and setting), on the amount of the fluid to be hardened and/or print speed. For a given printing machine and given print job, only the printing speed can be selected by the operator.
  • the amount of ink relevant for a given print job - for curing or its settings - is the maximum amount of ink that is actually achieved in the overprint of the colors involved, e.g. CMYK. If a "fixed" control field with e.g. 400% area coverage (4 times 100%) is used to check the degree of hardness in four-color printing, the problem could arise that the printing speed is selected lower than the maximum possible if the actual highest area coverage in the printed image is lower than that is in the control panel.
  • this object is achieved by a method according to claim 1 .
  • a method according to the invention for producing printed products, using a printing machine which can be operated at different speeds for printing and curing printing ink comprises the following steps: selecting a plurality of mutually different speeds; Printing a plurality of test products, at least one test product being printed at each speed and the test products each having a plurality of test fields with different color assignments; curing the test products, ie the test pads, at the selected speeds; detecting the values of respective degrees of hardness of the test fields; categorizing the values; storing the categorized values; and selecting a print speed from the speeds using at least one stored value; Printing and curing of several print products of a print job at the print speed.
  • the invention advantageously makes it possible to produce high-quality printed products, in particular high drying quality, at high production speeds, i.e. industrially.
  • the invention also advantageously makes it possible to determine a maximum printing speed, in particular to select it, preferably "printing process reliable", i.e. with the required quality of the print and/or curing, and preferably depending on the printing material or the material to be printed of a pending print job .
  • the ink can be, for example, offset ink, flexographic ink, gravure ink, varnish or inkjet ink.
  • the printing press can accordingly be, for example, an offset printing press, a flexographic printing press, a gravure printing press or an inkjet printing press or a printing press with at least one corresponding printing unit.

  • a device for recording is preferably used, e.g. a measuring device for measuring the curing or through-curing of the printing ink.
  • the categorizing is preferably done computationally, i.e. using a digital computer. Categories are preferably specified or formed. Categorizing may involve categorizing into several distinct levels of cure (“dry levels"), e.g., high (very good cure/drying), medium (good and adequate cure/drying), and low level (poor and insufficient curing/drying).
  • dry levels e.g., high (very good cure/drying), medium (good and adequate cure/drying), and low level (poor and insufficient curing/drying).
  • Storage is preferably carried out using arithmetic, ie using a digital computer and a digital memory.
  • the storage can take place in the printing machine or outside, for example on a digital memory of the printer or in a so-called cloud, for example a cloud of the printing machine manufacturer.
  • Selecting a print speed is preferably done computationally, i.e. using a digital computer.
  • the selected printing speed is preferably a high and particularly preferably a maximum printing speed with a given (alternatively: required) drying quality.
