Definitions

  • the invention relates to a method for producing test prints of individual colors or color combinations in a printing press.
  • DE-AS 15 36 449 a control device for a multi-color sheet-fed rotary offset printing machine has become known, in which selected blanket cylinders or any combination of blanket cylinders of the printing units are adjusted from a main operating point to the printing or non-printing position can. This ensures that sample prints of any color or color combination can be created with little effort.
  • a disadvantage of this control device is that the printer must switch the printer on or off. The number of sample prints made in a selected color or color combination cannot be determined exactly. There is a risk that too many sheets will be printed in a selected color or color combination, which ultimately means the printing of waste.
  • the invention has for its object to describe a method for the automatic preparation of color separations.
  • control device in which at least one control program can be stored, that this control program is constructed from individual program steps, and that the printing on and off in the individual printing units of the printing press take place in accordance with the stored program steps.
  • control program is selected from a program library.
  • this program library depending on the number of colors to be printed, for example, certain control programs are stored which automatically take into account all the test prints necessary for the assessment of the printed product, i.e. the type of color separation and the number of prints to be made.
  • control program can be constructed from freely programmable program steps. This measure gives the operating personnel the opportunity to create special test prints according to the desired requirements.
  • the development is to be regarded as particularly advantageous in that the number of prints to be carried out in the corresponding printing units of the printing press can be preselected for each individual program step.
  • This preselection of the sheets to be printed in one program step ensures that only as many test prints of a color or color combination are produced as are necessary for the assessment of the test print. This saves both costs and time.
  • a separating strip is automatically shot into the filing stack. This allows the printer to easily visually track where the trial print of a single color or combination of colors ends or where the next one begins.
  • the printing speed of the printing press be specified. This measure enables an optimal adaptation of the printing result to the actual printing process that follows at a later point in time.
  • the rubber blanket be automatically washed by non-employed blanket cylinders before, after or during the program run.
  • paper sheets are pre-stacked for printing, that the number of paper sheets is communicated to the control device and that the actual control program is only started after the paper sheets have been processed. It also proves to be advantageous here if the waste sheets are separated from the good sheets by automatic streaking. It is also provided that a preselected number of waste sheets is taken into account between two program steps.
  • a further advantageous measure is that a good sheet is automatically separated when the test print of a color or a color combination is created, so that the printer can carry out an assessment of the respective test print without additional effort.
  • the printing plates of the additional printing units to be employed are colored and over-moistened.
  • the invention is illustrated by the single figure.
  • FIG. 1 shows a schematic side view of a two-color sheet-fed printing press with a coupled control device for carrying out the method according to the invention.
  • a sheet-fed printing press 1 with two printing units 2, feeder 3 and delivery 4 is shown.
  • the individual printing units 2 themselves show the usual cylinder arrangement consisting of plate cylinder 5, blanket cylinder 6, printing cylinder 7 and transfer cylinder 8.
  • a reversing drum 9 is arranged between the two printing units 2.
  • a rotary encoder 11 is attached to the shaft of the register application drum 10. The information provided by the rotary encoder 11 about the respective angular position of the printing press 1 is passed on to the control device 12 via data lines, which is accommodated, for example, in a control cabinet.
