Definitions

  • the invention relates to a method for starting the production after a print interruption, in which the plate cylinder of a printing press during the printing process Color is supplied. This is done by storing the one in the color box Paint via an intermittent paint lifter on a multi-roller the inking unit assigned to the plate cylinder is transmitted. The plate cylinder is fed to fountain solution in the printing process via a dampening system. During the When the print is interrupted, the lifting stroke is stopped, the ink supply from the inking unit to the plate cylinder and the sheet run is interrupted and resumed The ink lifter is activated during the printing process after the print interruption.
  • Inking unit turns up after a certain number of machine revolutions for the continuous printing desired ink layer thickness on the contacting the printing form Inking rollers.
  • a color gradient occurs that affects the layer thickness between the rollers near the ink fountain and the inking rollers.
  • the inking rollers are switched off from the printing form and the ink supply through the ink lifter is interrupted.
  • both the ink profile on the ink application rollers is disturbed as also the color gradient is evened out.
  • the layer thickness on the inking rollers is too small and it takes a long time Time until the ink layer has reached the printing thickness. The result The resulting amount of waste significantly reduces the productivity of the printing press.
  • the process described in DE 44 36 953 C1 can also reduce the problem of color depletion do not loosen the rollers near the ink fountain.
  • a quantity of ink is introduced into the inking unit at the ink ductor, whereby this color quantity corresponds to the so-called basic color quantity of the order.
  • the upcoming print job set the required color profile until then the actual one Printing with release of the sheet run and the starting of the printing unit cylinder takes place.
  • the lifting strip width is provided set to a possible maximum value, d. H.
  • the lifter roller takes the largest possible amount of paint from the ink fountain pen and transfers it the ink rollers downstream of the ink lifter. It is also provided that the Printing machine is run up to the highest possible speed (if possible the maximum speed of the machine), so that the corresponding number of machine revolutions is run through in the shortest possible time.
  • the object of the invention is to develop a method by which the Incidence of waste is reduced.
  • the invention has the advantage that the printing press can now print faster comes.
  • the color depletion of the rollers near the ink fountain is counteracted and the ink / fountain solution balance is established earlier. This will make the waste reduced.
  • the pressure is interrupted, a known lift lock is used and thus the Ink supply to the inking unit interrupted.
  • the inking rollers turned off from the plate cylinder, so that their contact with the printing plate is interrupted becomes.
  • at least one pair of rollers can also be separated, so that two or more roll strands are created.
  • the time of the printing interruption detected and connected to a computing unit also not described in detail Control fed.
  • machine-related data such as number of rolls, diameter of the rolls, number and location of the roll separation and the like
  • job-related data is recorded or recorded there.
  • the lifter lock is deactivated in a first step. This provides the inking unit with color again. If there is one This separation is lifted. In the area near the ink fountain there are far fewer Roller pairs arranged so that here, due to the smaller number of Ink splitting processes, a larger ink layer thickness builds up on these rollers than on the rollers near the plate cylinders.
  • the time is calculated from the machine-related and job-related data, to which there is a gradient of ink layers close to the production on the ink box near Has trained rollers. In particular, it is also taken into account whether color strand separations available.
  • the time of commissioning the dampening system is also activated during the stroke cycle. It does that for some Jobs a faster adjustment of the ink / fountain solution balance. Furthermore is it is also possible to switch on the dampening unit between the time switching on the ink lifter and starting the sheet run.
  • the time for using the dampening system can be as well as the time of use the color lifter from the machine-related provided by the control and calculate job-related data.
