Definitions

  • the invention relates to a method and a device for supplying ink to printing presses.
  • the inking units are fed by printing machines with a finished starting color, which is usually printed unchanged on the paper web or the sheet.
  • a finished starting color which is usually printed unchanged on the paper web or the sheet.
  • papers with different qualities, surface properties, porosities or the like Other differences, however, different color saturations or so-called color depths in the print can result with the same starting color.
  • the thickness of the ink layer required for a full tone is less than in the case of more absorbent papers, which take on the ink more strongly and which result in a greater ink layer thickness.
  • the dot gain of the halftone dot changes depending on the applied color layer thickness and thus increases the area coverage of the halftone dot, which leads to a change in color tone compared to the original.
  • the color saturation within the ink supply device of an offset printing press can be changed and adapted to the values desired in each case, such as solid density, tonal value increase and color saturation.
  • This has the advantage that you can work with conventional and existing starting colors. This reduces the number of starting colors used, which reduces storage and maintenance costs, especially cleaning.
  • the color saturation can be adjusted much more precisely to the respectively required value and the type of printing medium currently being used, for example to different types of paper, by adjusting within the ink supply. There are much finer gradations, so that there is an optimal adjustment option for all printing media.
  • the printing media can be of any type, for example foils, webs or sheets made of plastic, metal or the like, textile materials, etc.
  • each with a saturated, preferably maximally color saturated Starting color worked adjusting the saturation by adding a pigment-free and preferably transparent colorless ink carrier is achieved.
  • the Ink carrier which is also known as printing white, preferably contains all components of the original color with the exception of the color pigments.
  • the mixture of color carriers and the starting color then forms the printing ink.
  • the Color carrier is preferably the same as that in the starting color.
  • the Adjustment device as close as possible to the place of printing and preferably on the inking unit of the printing press arranged. This will make the color saturation shortly before Printing set on paper. Error influences in the Area between saturation adjustment and pressure minimized or completely switched off. Moreover can the color supply in the Initial state remain. This brings advantages to the Cleaning and maintenance of the individual ink-carrying parts the ink supply device with itself.

In the preferred embodiment it is as Mixing valve designed and as close as possible to the pressure point the ink ribbon paper web, e.g. in the area of a color box. For this it is convenient that Mount the mixing device on a beam that is arranged above the color box. The color saturation is then immediately before filling the color box with Color set. Inside the ink fountain until printing then it can hardly with normal operation of the printing machine more about negative influences or changes in set color saturation of the printing ink.
  • the adapter also offers the possibility of To influence color in another way.
  • the change in viscosity is independent of the change in Color saturation.
  • the viscosity influence is from Advantage to thermal changes on the press compensate. This is especially true for the magenta color cheap because this is due to thermal changes during the Process runtime reacts more sensitively than the others Basic colors cyan and yellow.
  • Direct colors from several starting colors can be mixed. This is advantageously done with six main colors, namely yellow, magenta, cyan, violet blue, green and orange-red as well as black and possibly also white worked.
  • This mixture of a direct color will preferably with the adjustment of the above Color saturation combined.
  • the mixture of a direct color can also work alone and without influencing the Color saturation can be used.

Therefor the unprinted paper surface of the front and Back optically scanned and in front of the paper feed provides the control unit with the color saturation of the printing paper necessary data. With that Differences in the quality of the paper for rolls or Paper pallet change recognized and the set one Color saturation corrected.
