The support printing unit is dimensioned and arranged in such a manner that the support printing unit provides a support for the measuring strip printing unit opposite the undesired local printing pressure increase. An independent claim is also included for a method for printing a printing substrate by a printing system.

Description

  • The The invention relates to a printing system according to the The preamble of claim 1 and a method of printing on Print media according to the preamble of Claim 10.
  • The in question printing plant is increasingly used today Printing foil-like plastic packaging. Here is the printing system associated with a printing press with multiple printing units, too be referred to as inking. The printing works work after one High-pressure process and each have a printing forme cylinder a printing form and the print carrier leading Impression cylinder on. In the high-pressure process, for example, too the flexographic printing method is one that is the printing form with Equipped with printing elements and non-printing elements. The printing elements are realized as surveys on the printing form. While In the printing process, the printing elements transfer the printing ink on the print carrier.
  • in the The area of printing on packaging is particularly important on that the resulting image impression the target specifications exactly and reproducibly complies.
  • In front In this background, it has long been known that beside the original printed image with a colorimeter several measuring fields at one point on the print carrier is printed when using the packaging, for example by turning over an edge o. The like., No longer visible. Such Color measuring strips often have several measuring fields different grid density on. Each printing unit prints a portion of the Farbmeßstreifens in the respective Printing unit assigned printing ink.
  • The known printing system ( EP 0 228 347 B2 ), from which the invention proceeds, follows the above idea of producing a Farbmeßstreifens on the print carrier. The printing system is equipped here with a measuring device for measuring the spectral reflectances of the individual measuring fields of the Farbmeßstreifens. In an evaluation unit, the printing parameters of the individual printing units are corrected based on the measurement result sen and on specific target specifications.
  • With the above correction of the printing parameters based on the colorimetric Measurement of the measuring fields can be sources of error "compensated" over the entire width of the plate cylinder seen an identical influence on the print result to have. The most arranged on the edge of the original printed image Measuring fields become a kind of representative measured for the original printed image.
  • Problematic However, sources of error that only affect a subset of the Printing forme cylinder, for example only on the edge of the plate cylinder, Act. For example, this may be machine vibrations or local deformations due to centrifugal forces o. Like. Act. The consequence of such local error sources exists often in unwanted local pressure increases. Especially When flexographic printing with compliant printing form, it comes to a local deformation of the printing plate, which basically with associated with a corresponding gradation.
  • It is obvious that such, in the extreme case exclusively on the Farbmeßstreifen acting, unwanted Increasing the pressure and possibly local deformation of the printing form to a distortion of the overall measurement result and subsequently leads to correction errors.
  • At the largest are the resulting correction errors logically with measuring fields of low grid density, since there is already enough pressure increase to a significant deformation of the printing form with a considerable resulting To effect gradation.
  • Of the Invention is based on the problem, the known printing system such to design and develop that by unwanted, local pressure force increases generated correction errors reduced become.
  • The above problem is in a printing system according to the The preamble of claim 1 by the features of the characterizing one Part of claim 1 solved.
  • Essential is the consideration that the gauge pressure elements against unwanted local pressure force increases effectively protected by appropriate support can be.
  • Essential is further that the above support simply by can be realized that the printing forme in the field of Measuring strip pressure elements additionally a support pressure element having. A local pressure increase will be during the printing process via the measuring strip printing elements on the one hand and passed over the support pressure element on the other. The arrangement can be easily interpreted so that in particular in the area of the measuring strip printing elements with low screen density the largest part of the pressure force increase over the support pressure element runs.
  • Overall, one could also say that the Meßstreifen-pressure elements by the support pressures Element of undesirable, local Druckkrafterhöhungen be largely decoupled, which again applies in particular to the measuring strip printing elements with low grid density.
  • Especially Advantageously applicable is the inventive Solution in flexographic printing (claim 2). This is because that the correction errors to be avoided then greatest are when the printing form is designed elastic.
  • at the further preferred embodiment according to claim 5, the support pressure element is a straight web. tries have shown that hereby optimal support is achievable.
  • To another doctrine, which has its own significance, The method for printing on print media by claimed a printing system described above. It is essential in that during the printing of the Farbmeßstreifens on the print carrier, the support pressure element simultaneously to one or more of the gage pressure elements in Engages the print carrier, which ultimately the top corresponds described supporting process. On the above Designs may be referred to insofar.
  • Further Details, features, objects and advantages of the present invention will be described below with reference to the drawing of a preferred embodiment explained in more detail. In the drawing shows
  • 1 the basic structure of a printing unit of a printing system according to the invention,
  • 2 the printing forme cylinder in 1 illustrated printing machine,
  • 3 in a very schematic representation by means of the printing system according to 1 next to the original printed image generated colorimeter.

  • The printing system has a printing press, which in turn with at least one printing unit 1 for printing on a print carrier 2 with a the printing unit 1 assigned printing ink is equipped. In general, the printing press will be equipped for multi-color printing and accordingly several printing units 1 exhibit. If following from a printing unit 1 the speech is, so are all possibly existing printing units meant.
  • The printing unit 1 works according to a high-pressure method, preferably according to the flexographic printing method, which will be explained in more detail below.
  • The printing unit 1 has a printing plate cylinder 3 with a printing form 4 on. The printing form 4 is, as usual in a high-pressure process, with pressure elements 5 and non-printing elements 6 fitted. When printing the print carrier 2 it is envisaged that the ink on the printing elements 5 on the print carrier 2 is applied. The same applies to the printing elements 5 around elevations and non-pressure elements 6 around recesses in the printing form 4 ,
  • At the in 1 illustrated embodiment is also a print carrier 2 leading impression cylinder 7 intended. The pressure force thus runs from the plate cylinder 3 over the print carrier 2 on the impression cylinder 7 ,
  • The representation in 1 furthermore, it is apparent from the printing form cylinder 3 associated anilox roller 3a that with a paint supply 3b corresponds. The anilox roller 3a is pressurized with ink and gives this ink in a known manner to the printing plate 4 from.
  • In 2 is the printing form 4 of the printing unit 1 shown. The printing form 4 is so made that the printing unit 1 on the print carrier 2 next to the original printed image 8th a colorimeter 9 with several measuring fields 10 different screen densities prints. For this purpose, the printing form 4 corresponding measuring strip printing elements 11 on. With measuring strip pressure element 11 in the present case, in each case, the rasterized or, in the case of a full-tone measuring field, non-rastered surface area of the printing form 4 summarized, the one to the measuring fields 10 corresponds. A gauge pressure element 11 Thus, if necessary, comprises a plurality of singular printing elements explained above 5 and non-printing elements 6 ,
  • The printed colorimeter 9 is in 3 shown. It can be the very schematic sectional view in 2 infer that in 2 Seen from top to bottom, the screen density of the measuring fields 10 or the associated measuring strip printing elements 11 decreases.
  • The representation in 2 can also be seen that the printing form 4 in the area of the measuring strip pressure elements 11 in addition a support pressure element 12 has, which is designed in a preferred embodiment in the manner of a full-tone printing element. But it can also be configured rasterized and then includes, as in connection with the measuring strip printing elements 11 addressed, several singular Druckele explained above mente 5 and non-printing elements 6 , Depending on the configuration, the support pressure element prints 12 a corresponding support picture 13 on the print carrier 2 ,
  • It is essential that the support pressure element 12 is sized and arranged to provide support for the gauge strip printing elements during the printing process 11 provides against undesirable, local pressure force increases. It has been explained that such local pressure force increases may arise due to machine vibrations, local deformations or the like.
  • For the achievement of the supporting effect, it is necessary that during the printing of the Farbmeßstreifens 9 on the print carrier 2 the support pressure element 12 simultaneously to one or more of the gauge strip printing elements 11 in engagement with the print carrier 2 comes.
  • Particularly advantageous teaching of the invention is applicable to flexographic printing. Then the printing form 4 designed as a flexographic printing cliché. A local pressure increase in the region of a measuring strip pressure element 11 leads in particular at low halftone densities to deformations of the printing plate 4 , which leads to an undesired gradation and as a result to a falsification of the measurement result. This was explained above.
  • Preferably, it is therefore provided that the support by the support pressure element 12 a deformation of the measuring strip pressure elements 11 counteracts and / or completely prevents this deformation. Ultimately, it depends on a suitable design of the support pressure element 12 at.
  • At the in 2 illustrated and so far preferred embodiment are the Meßstreifen-printing elements 11 designed so that the printed measuring fields 10 arranged in a row and adjacent to each other. Basically, the printed measuring fields 10 but also be spaced from each other. Further preferably, it is such that the measuring strip pressure elements 11 and thus the printed measuring fields 10 are each designed substantially rectangular. In principle, however, it can also be provided that the measuring strip printing elements 11 take any shape. It is conceivable, for example, a circular design.
  • The measuring strip pressure elements 11 are preferably designed so that the measuring fields 10 in addition to a full-tone measuring field include a plurality of undertone measuring fields with graduated screen density. Preferably, a full tone measuring field is followed by a 75% undertone measuring field, a 50% undertone measuring field and a 25% undertone measuring field. Of course, this order can vary largely arbitrarily.
  • In the support pressure element 12 it is preferably a straight web, along the measuring strip pressure elements 11 runs, in which case and preferably the support pressure element 12 to the gauge pressure elements 11 borders. In principle, between the measuring strip printing elements 11 and between the support pressure element 12 and the gauge pressure elements 11 Also column o. The like. Be provided. The web-like support pressure element 12 preferably runs parallel to the circumferential direction of the printing forme cylinder 3 ,

In the web-like support pressure element 12 the width is at least about 20% of the width of the measuring strip printing elements 11 ,
  • It is also a different shape of the support pressure element 12 conceivable. In principle, the support pressure element 12 be designed in several parts. It is also conceivable that the support-pressure element 12 the gauge strip printing elements 11 completely or completely encloses. As a result, the supporting effect can be further increased.
  • It was explained above that the printing press of the proposed printing system preferably serves the multi-color printing and correspondingly more printing units 1 are provided, each associated with different printing inks. The individual printing units 1 generate on the print carrier 2 a resulting colorimeter 9 and have for this purpose each gauge strip printing elements 11 at the respective different positions on the printing form 4 on. So it is so that the printing form 4 one of the printing units 1 in each case a part of the measuring strip printing elements 11 having the gauge pressure elements 11 total the measuring fields 10 of the colorimeter 9 produce.
  • It is different according to a preferred embodiment of the support pressure element 12 , Preferably, it is so that the printing forms 4 in each case a support pressure element 12 exhibit that on all printing forms 4 has an identical position and shape.
  • It is particularly advantageous if the printing system is a measuring device, not shown, for measuring the spectral remissions of the measuring fields 10 of the colorimeter 9 wherein an evaluation unit, also not shown, from the measuring color coordinates and from nominal color coordinates changed printing parameters for the respective printing unit 1 generated. It may be provided that the evaluation has a user interface for outputting the changed printing parameters and / or that the evaluation unit, the changed printing parameters to the control of the respective printing unit 1 via a data connection in the manner of a closed loop directs. Together with the above-described, optimized application of the Farbmeßstreifens 9 With such an arrangement, a particularly high print quality can be achieved.
  • According to another teaching, which has independent significance, is a method for printing on print media 2 claimed by means of a printing system described above.
  • It is essential according to this further teaching that during the printing of Farbmeßstreifens 9 on the print carrier 2 the support pressure element 12 simultaneously to one or more of the gauge strip printing elements 11 in engagement with the print carrier 2 comes. With the simultaneous engaging is the support described above by means of the support-pressure element 12 meant.
