Definitions

  • the invention relates to a method for controlling the coloring in the production of printed products on printing machines according to the preamble of claim 1.
  • the color is controlled by changing the dampening solution and / or ink flow.
  • the speed of the dampening or inking ducts in the dampening or inking unit of the printing press is set to a specific value depending on the printing speed.
  • Such controls for a dampening or inking unit are known from GB 2 193 926 A and DE 3 832 527 C2.
  • the necessity of changing the speed of the ductors when the printing speed changes results from the fact that more dampening solution and ink are consumed at a high printing speed per unit of time.
  • the reverse effect can occur if the printing speed is slowly reduced from the production speed to a lower speed, for example to initiate a print interruption for washing the rubber blankets or for changing the stack.
  • the balance set at the high printing speed in the inking / dampening unit also has a negative effect.
  • a certain number of sheets are slightly over-inked when the printing speed is reduced and, under certain circumstances, can also be over-wet for the paper quality.
  • the object of the present invention is therefore to expand a method according to the preamble of claim 1 in such a way that changes in coloration on the printing material which lead to waste can be avoided when the printing speed is changed.
  • a sheetfed offset printing machine that, after the command for a speed change has been entered, the speed of the dampening and / or inking device is first ramped up to a value corresponding to the predetermined machine speed after a specific time function and then after a certain number of machine revolutions, the change in printing speed is also carried out according to a predetermined time function.
  • the opening widths of the ink metering devices can be changed to a value corresponding to the new machine speed.
  • Initiation of the temporal change in speed for the dampening and inking unit as well as initiation of the change in the printing speed is carried out by correspondingly controlling the main drive in relation to a specific position of the lifting gear.
  • the method according to the invention is preferably used in sheet-fed offset printing machines and there for controlling the fountain solution or ink supply or in combination.
  • the time ramp, after which the printing speed (machine speed) is increased or decreased, is chosen in particular in such a way that the drive torsions which have an adverse effect on the registration quality are as low as possible.
  • the method according to the invention is preferably carried out by a suitably programmed control which is operatively connected to the corresponding drive means for supplying the ink and / or fountain solution on the one hand and to the main drive of the printing press on the other.
  • the controller also detects the machine speed (printing speed).
  • the control then carries out the pre-control of the supply of moisture and / or ink according to the invention whenever an increase or decrease in the printing speed is entered, for example, via the control station of the printing press or via appropriate input means on the printing units.
  • the number of machine revolutions M is plotted on the abscissa.
  • the ordinate stands in each case for the value of the speed of the machine DM or for the speed value of a ductor DD, the speed value DM of a color ductor being reproduced in the lower diagram, for example.
  • the printing press runs at a speed DM of, for example, 5,000 sheets / h. It is assumed that the command to increase the printing speed DM to 10,000 sheets / h is given at time T1. Now the duct speed is raised either from a lower value D5000 to an upper value D10,000 according to a predetermined time function (time ramp) for the purpose of synchronization with the jack. D5000 and D10.000 are to be understood as those duct speed values DD which are to be set at the respective printing speeds.
  • the start of the printing speed DM from the start value to the intended end value takes place at a time T2 after a predetermined time function.
  • a certain speed increase is carried out per unit of time.
  • the printing press thus reaches the intended printing speed DM of 10,000 sheets / h.
  • the time functions according to which the increase or decrease in the speed of the printing press DM and the speed of the ductors are to be carried out are also to be determined empirically in printing tests. In particular, it can be provided that the same time functions are used.
  • an increase in the printing speed DM was described.
  • the procedure for reducing the printing speed DM is exactly the same.
  • the printing speed DM is slowed down from a production value, for example, to the basic speed after the corresponding reduction in the number of ductors DD.
  • the same but also different time functions or delay values in revolutions of the machine can be used as when the printing speed DM or the ductor speed DD is ramped up. It can also be provided that - in contrast to the described case according to FIG. - the intervals for starting up the printing speed DM and starting up the duct speed DD overlap.
