Definitions

  • the invention relates to a print control strip for controlling and monitoring the printing process on, in particular, autotypically operating printing machines according to the preamble of claim 1.
  • the photoelectric scanning can be carried out by means of a handheld or traversing densitometer, by means of a spectral photometer, by means of a color measuring device or a video measuring head.
  • the individual measuring fields of the print control strip are designed, for example, as measuring fields of the full tone, the halftone tone (predetermined area coverage), halftone fields of the overprinting (gray balance), etc.
  • setting values for, in particular, the ink guidance of the printing press are derived from the photoelectric measurement values obtained in this way, which takes place in particular in an automatic color control system.
  • the print control strip thus has corresponding measurement fields, for example of the full tone, for each color to be printed in all or in a multiplicity of color metering zones.
  • measurement fields for example of the full tone
  • control fields for direct control or regulation of the coloring
  • diagnostic fields are usually also provided, which provide further information about, for example, the dampening solution guide, pushing / duplicating or other process sizes.
  • a print control strip for each color to be printed should have control fields (full tone) for direct control and additionally distributed over the print width some diagnostic fields for monitoring the printing process for each color to be printed, and the width of the ink metering zones on an ink fountain roller, for example, is only 30 mm, can with a measuring field size between 3 and 5 mm max. 6 to 10 measuring fields (control and diagnostic fields) can be accommodated per ink metering zone.
  • control and diagnostic fields can be accommodated per ink metering zone.
  • Print control strips for checking / diagnosing 6 or 8 printing colors are common and widespread.
  • a six-color print job is printed with a print control strip for, for example, 8 colors, i.e. if only 6 measurement strip excerpts are copied from the print control strip with its 8 measurement strip extracts to the corresponding 6 printing plates, the places on the print sheet in the print control strip where the measurement strip extracts not copied have measurement fields remain , unprinted.
  • Examples of the pressure control strips of the type concerned by the present invention are known from DE 3 643 721 A1, DE 4 038 574 C1 and, as far as the procedure for the assembly of the measuring strip extracts is concerned, from DE 3 219 744 C2.
  • the object of the present invention is therefore to develop the print control strip in such a way that a variable and convenient copy of the measuring fields for the individual printing inks is possible in accordance with the intended number of colors to be printed and in accordance with the process requirements.
  • the measuring strip extracts of the print control strip for at least one color are present multiple times, so that a measuring strip extract with the corresponding control fields at the places provided for this color and at least one further, alternatively, for this color using the measuring strip extract with diagnostic fields instead of the control fields. If this color is not printed at the same time, instead of the measuring strip extract with the control fields, the measuring strip extract with the diagnostic fields, which is provided as an alternative, is also copied with the measuring strip extract of another color to be printed. The consequence of this is that for this color not only measuring fields as control fields but additionally also at precisely those places where the color that was not printed would have measuring fields, correspondingly designed diagnostic fields in the Print control strips are included.
  • a total of two sets of measuring strip extracts are provided for a print control strip, which, for example, should only contain measuring fields of the full tone as control fields.
  • the first set of measurement strip extracts comprises a total of N films, where N is the number of colors for which the print control strip is designed.
  • the individual measuring fields are arranged according to the copying process (positive / negative) as correspondingly blackened areas on transparent material or as non-blackened areas in correspondingly opaque carrier material.
  • the second set of measuring strip extracts which is to be used as an alternative, differs from the first set of measuring strip extracts in that the individual measuring fields in the films are not designed as control fields for the full tone, but rather as corresponding diagnostic fields (coarse, fine grid, micro measuring elements, sliding / duplicating fields, etc.) are.
  • the diagnostic fields do not have to be the same everywhere, but rather it can be advantageous to have diagnostic fields with different halftone values, for example alternating from ink metering zone to ink metering zone.
  • the corresponding 6 measuring strip extracts with the corresponding control fields of the full tone are assigned to the 6 colors copied corresponding printing plates.
  • the total of the set of measuring strip extracts with the control fields of the full tone thus remains 4 measuring strip extracts not used.
  • the measuring strip extracts with diagnostic fields provided as an alternative are now used, a measuring strip extract with diagnostic fields being additionally copied with the measuring strip extract from the control fields onto a printing plate of a color to be printed.
  • the print control strip instead of a total of 2 sets of measuring strip extracts for the print control strip (max. N colors), several sets of measuring strip extracts can also be provided. It would be conceivable that, in addition to the N films for the N colors in each case, two further sets of measuring strip extracts for the diagnostic fields are provided in the first set of measuring strip extracts for the control fields, the one set of measuring strip extracts diagnostic fields each as measuring fields of the screen tone of, for example, 40% and the further set of measuring strip extracts has diagnostic fields as halftone measuring fields with, for example, 80% area coverage in the film. Are then from the max. N possible colors for this print control strip, two not printed, so it is possible to print two different diagnostic fields (screen tone 40% and 80%) for a printed color or a total of two different colors next to the control fields, one diagnostic field with one each to provide certain grid tone coverage.
  • Fig. 1 is shown with P a part of a printed sheet in the region of its front edge.
  • a print control strip DK consisting of individual measuring fields MF for the respective colors was also printed on this.
  • the individual color metering zones are shown in dashed lines and numbered starting with 1.
  • the width of an ink metering zone is 30 mm and that a measuring field MF has a width of 3 mm. This means that max. 10 measuring fields are provided and in the configuration of the print control strip DK to be explained, a total of 10 colors would have to be regulated.
  • MA1.1, MA2.1, ...., MA10.1 show the various measuring strip extracts to be copied onto the respective printing plates (or the films) of the individual colors.
  • the measuring field MF takes the first position from the left in each color metering zone.
  • the measuring field MF assumes the second position in each ink metering zone in the measuring strip extract MA2.1 for this printing ink.
  • a measuring strip extract MA1.1, ...., MA6.1 would have to be copied accordingly for the six colors to be printed on the six printing plates (or their films). Accordingly, the measuring strip extracts MA7.1, ...., MA10.1 remained unused.
  • FIG. 2 shows the diagram of the several sets of measuring strip extracts MA1-10.1, MA1-10.2, MA1-10.3 etc. provided.
  • the measuring strip extracts MA7.1, ...., MA10.1 are not used remain, for example four measuring strip extracts MA7.2, ...., MA10.2 are selected from the second set of measuring strip extracts MA1-10.2 and one extract of this second set together with a measuring strip extract MA1.1, ...., MA4. 1 of the first sentence copied onto the respective printing plate (or film).
  • diagnostic fields e.g. raster
  • the second set of measuring strip extracts MA1-10.2 could each have diagnostic fields as measuring fields MF of the Screen tones with 40% area coverage and the third set of measuring strip extracts MA1-10.3 each contain diagnostic fields in the screen tone with 80% area coverage.
  • a further measuring strip extract with diagnostic fields is provided for each measuring strip extract with control fields of the first set.
  • a further measuring strip extract with diagnostic fields is provided for each measuring strip extract with control fields of the first set.
  • the first 4 printing colors which are mostly occupied by the 3 chromatic colors in addition to black
  • only four individual measuring strip extracts with only control fields of the full tone are provided, and for the other six colors, for example, a set of measuring strip extracts with control fields of the full tone as well as one second or additional sets of measuring strip extracts, each with diagnostic fields of the raster tone or other training are provided.
  • the so-called control fields were designed as measuring fields of the full tone
  • the diagnostic fields in the measuring strip extracts to be used alternatively were, for example, measuring fields of the raster tone.
  • the measuring fields of the first set of measuring strip extracts can also be designed as measuring fields of the grid tone (specific area coverage) and the diagnostic fields in the second, third, etc. measuring strip extracts, which may also be copied, as measuring fields of the full tone, the grid tone (with different area coverage) or other structuring be.
