This takes place online and directly by means of suitable physical measuring methods, the measured values being taken directly from the pressure and, as a matter of principle, an evaluation of the measured values as to how far they represent a relevant error can not be made.
  • a repeat In order to check print results, a repeat, generally sometimes referred to as a proof, is generally cumulatively or alternatively compared with a corresponding template.

  • the template may for example be made of paper or as a label (return pattern).
  • an electronic document or a graphics file or the like can serve as a template. With a report, the reliability and quality of the printing with respect to the original can be proven or ensured.

  • the length of the respective repeat corresponds to the period length of the corresponding printing device in the case of rotating printing cylinders
  • Rolls or -siebe is a rapport preferably as long as a circumference of the largest printing cylinder or the largest pressure roller or the same length as the largest printing screen

  • Corresponding reports can also be checked in continuous printing processes, such as for example gravure printing (decor printing), web offset or continuous roll flexo printing (label production, film printing). It is also conceivable, in particular, for the corresponding test inline, ie for the entire material to be printed or for each individual pressure, whereby also here the problem that a multiplicity of identical uses must be examined, occurs.
  • DE 195 25 186 AI discloses a method for determining measurement locations in the scanning of printed products, which can work with a variety of benefits Here are determined by a user manually certain easily recognizable locations of individual benefits, this always the In this way, a measuring location following this can first be selected for a benefit and then readily transferred to the other uses by transmitting the relative position to the previously selected first location
  • the invention proposes a method for checking printed results, in which first a rapport, for example taken by a scanner, then selected on the repeat benefits and the selected benefits are compared with a template

  • Such a benefit selection is particularly advantageous over a mere geometric marking of a benefit, which is then transferred by linear transformation to the other benefits, since a benefit as such is selected and can be "recognized" by the data processing system, as will be explained in more detail below
  • the benefit selection is preferably automatic, which can be realized, for example, that a recorded area is searched for repetitive patterns This is preferably not done with the highest accuracy, so that individual errors do not affect the benefit selection
  • a manual or semi-automatic benefit selection is conceivable, in particular under adverse operating conditions, however, an automatic benefit selection, in particular accompanied by automatic benefit recognition, is to be preferred
  • the selected benefits are compared with the template only after the benefit selection, wherein, depending on the specific embodiment of the invention, for example already during the benefit selection, a pre-comparison can be carried out within certain limits, which serves to select the individual benefits For example, by comparing the template with individual areas of the repeat under a relatively large tolerance threshold In this way, each a specific area of a repeat can be defined as a benefit or select if this agrees with the template within the appropriate tolerance threshold
