Definitions

  • the invention relates to a method for setting a production ink profile of an offset printing machine with a dampening and inking unit, which has an ink metering device for zone-by-zone adjustment of a color profile according to the required amount of ink, the application rollers of the inking and dampening unit being moved to the printing form in the system position.
  • the inking unit In offset printing machines, it is necessary that a thin ink film is fed to the printing form wetted with dampening solution.
  • An inking unit provided with a large number of rollers is used for this.
  • the dampening solution is supplied by means of a dampening unit, which also has a roller arrangement.
  • a dampening unit which also has a roller arrangement.
  • an appropriately adapted color distribution (color profile) across the printing direction of the offset printing press is required in order to achieve a good printing result.
  • the inking unit therefore has a color metering device which allows the zonal setting of a color profile. Depending on the setting of the individual zones, a corresponding color layer thickness results.
  • the ink is fed from a paint box using a color ductor.
  • the printer has the task of making the zonally required setting of the color metering device depending on the subject color requirements.
  • a so-called ink run-in is also carried out, in which the said color film is built up within the inking unit.
  • displaceable application rollers took up a distance from the printing form at the ink inlet, so that the printing form was not yet colored.
  • the color is also at the ink inlet by traversing friction rollers distributed laterally.
  • the color profile built up by the ink metering device during the ink run-in is evened out to a certain extent so that it is not immediately available to the desired extent at the start of printing.
  • the color profile set zonally on the ink metering device is reconstructed by the interaction and reaction of application rollers and printing form.
  • This measure of the known design according to the invention has made it possible to greatly reduce the amount of waste previously incurred.
  • a color profile corresponding to the production run is quickly achieved.
  • the ink feed results in a color distribution in the inking unit which oversubscribes the desired color profile, ie a higher or lower maximum or Minimum of the zonal ink layer thickness.
  • this effect of overdrawing occurs in subjects with very different zonal color density.
  • the printer has so far manually added paint to the relevant zone areas by means of a spatula in order to at least be able to start the printing process and not to have major problems in the production process.
  • the ink-water balance is disturbed in the case of non-ink-carrying parts of the image.
  • the object of the invention is now to achieve a color profile corresponding to the production run as quickly as possible and to avoid further waste.
  • This object is achieved in that in a first step the amount of ink is controlled so that a color profile inverse to the average ink consumption is generated compared to the desired color profile for the production state and in a second step the amount of ink is controlled so that it corresponds to the desired production color profile.
  • the oversubscription of the color profile described above is currently being used for the invention. It has surprisingly been shown that the production status is achieved much faster and without further waste if you first set the ink metering device so that an inverse color profile is generated, and then adjust the ink metering elements to the optimal production status during the ink run-in.
  • the ink / dampening agent weight is optimal for continuous printing.
  • a color gradient corresponding to reality is built up in the entire inking unit without using the usual waste paper advance. H. without first feeding and printing sheets through the press. This method for quickly reaching the optimal production status is used at the start of printing after interruptions in the printing process, such as. B. with a new start every day after washing the blanket or after changing orders.
  • the amount of ink is supplied in the second step in such a way that it adapts zone by zone to the desired production profile regardless of the distance of the inverse color profile from the desired production color profile.
  • the amount of dampening agent is reduced compared to the amount of dampening agent supplied during production during the ink supply with an inverse color profile.
  • the inverse color profile is set via an electronic computing and control device.
  • the optimal continuous printing color profile is detected by means of a plate reader, which determines the area coverage per zone, then the appropriate inverse color profile is determined using this data, and the ink metering device is then set accordingly.
  • the production printing profile can also be preset with a light pen or keyboard and then carried out accordingly with the computing device according to the invention.
  • the advantages achieved with the invention are, in particular, to achieve the fastest possible and optimal production status, with only a minor one Amount of waste is incurred.
  • the use of the inverse color profile creates an ideal color-water balance achieved. Lubrication and emulsification are avoided. In particular, the production process is optimally prepared for larger orders.
  • FIG. 3 shows the average value of the solid color density D V as a function of the number of sheets B Z.
  • the horizontal curves a and b show the waste in the case of overstaining or understaining.
  • the setting is optimal if, as the curve I shows, it lies between the horizontal lines a and b.
  • the dotted curve I strives for the ideal final value after a relatively small number of arches
  • the solid curve II which corresponds to the setting of the ink layer thickness without inverse control, only reaches the optimum state later. This eliminates the need for previous waste paper sheets (approx. 100-300 sheets) and the production process can be started with very little waste (10 to 50 sheets).
