Description

  • The invention relates to a method according to the preamble of claims 1 and 17.
    It should be noted that there is a need to adjust the print image by optimizing the relative position of the rollers involved in the inking and printing process in all areas of the rotary printing. Thus, in gravure printing machines, the position of the impression roller is set to the pressure roller.
    In flexographic printing machines, the impression cylinder, the pressure roller and the anilox roller must be adjusted to each other.
  • Therefore, flexographic printing machines are known, which are equipped with a pressure roller and an anilox roller, which are movable on at least one console of the printing press frame. These two rollers can be employed by their own actuators both independently of each other and together to the impression cylinder on which the printing material is applied.
  • So show the DE 29 41 521 A1 and DE 37 42 129 A1 Printing machines, bel which the bearing blocks of the printing cylinder-carrying carriage In slide guides the inking unit of the printing machine frame and provided with its own spindle drives and in which the Schiltten the printing cylinder are provided with further slide guides for the bearing blocks of the inking or anilox rollers carrying carriage, in turn have their own spindle drives.
  • Out DE 40 01 735 A 1 a flexographic printing machine is known, in which the carriage carrying the pressure roller and carrying the inking or rest roller carriage in a common carriage guide of the inking unit of the printing press out and together and individually by Spindetantriebe be moved.
  • In rotary printing machines of this known type, the adjustment of the printed image in a known manner can be done as follows. An electronic control device is provided which can access data entered into a memory device. The data relate to the travel between the pressure and the back pressure, taking into account the geometrical dimensions of the machine and the diameter of the rollers. This control device then adjusts the relative roller positions so that it is ensured that all parts of the printed image are transferred.
    However, the various rollers, printing plates and the materials to be printed and all other parts involved geometric tolerances, so often an additional Beistellvorgang is necessary.
    This loading operation is performed by the print engine operator, who adjusts the roll positions while observing the print image.
    By this type of adjustment of the printed image is ensured that with minimal pressure of the rollers involved in the printing process against each other a good print image is obtained. However, this type of adjustment of the printed image is cumbersome, requires a lot of time and waste and is also disadvantageous in that it depends on the subjective assessment of the printing press operator by visual inspection.
  • The object of the invention is therefore to provide a method of the type described, which allow automatic adjustment of the printed image to the desired optimum quality.
  • According to the invention this object is achieved by all features of independent claim 1.
  • It is advantageous in this context, if a control program is provided, which the geometrical dimensions of the rollers involved in the printing and inking process are known and which optionally (for example, in long steep paths, or after a roll change) the position of these rollers to each other by signals to the actuator drives provisionally established.
    However, the method according to the invention also works if there is no additional control program.
  • In an advantageous embodiment of the invention, it is provided that the digitized desired shape of the printed image is stored in the memory unit. This desired shape is then (possibly in the control device) compared with the respective recorded print image. The control device then generates actuating signals for the actuators moving the rollers until the comparison yields the best match between the recorded print image and its stored desired shape.
  • Another embodiment of the invention does not require a stored in a memory digitized desired form. In this further embodiment, use is made of the fact that the intensity of the reflected light of different sections of the printed image as a function of the relative roller position has a characteristic course.
    Thus, the intensity of the reflected light does not change unless contact is made between all the rollers involved in the printing or inking process. When the contact is made, the ink transfer to the substrate and the intensity of the reflected begins Light changes relatively strong until an optimum value of the color transfer is reached. A further approximation of the rollers then leads only to a smaller change in the intensity of the reflected light.
    In the region in which the intensity change flattened, an optimum between ink transfer and contact pressure of the rollers is usually achieved against each other. A further mutual approach of the rollers then only builds up pressure, which can lead to damage to the rollers, roller bearings, printing plates, materials to be printed, etc.
  • For this reason, it is advantageous to disassemble the recorded print image into different sections, or to take it with a camera, which receives a plurality of image sections.
    In the evaluation of the image sections, the mentioned course of the light intensity is recorded for the individual image sections.
    Only when a sufficient number of image sections have a certain selected intensity profile, the mutual approach of the rollers to each other is terminated. With high demands on the print quality, this will be the case when the change in the intensity of all image sections decreases or has already decreased. This ensures that a good ink transfer takes place on all sections of the printed image.
  • An improvement of this embodiment can be achieved if there is a difference between the intensity values of the printed substrate and the intensity values of the unprinted substrate. The obtained difference values are called contrast values below. They can be used in a similar way as the intensity values.
  • As a further advantageous measure, the use of at least one color camera is recommended, so that light of selected wavelength ranges can be recorded. This measure is suitable both to facilitate the comparison with a stored digitized desired form of the printed image and to carry out the course of the light intensity or the contrast values in an improved form. Commercially available cameras of modern design usually have as photosensitive elements semiconductor devices that are sensitive to light of certain wavelengths, which is due to the photoelectric effect and its applications in the semiconductor field. It is expedient for a camera in this way to be able to assign electrical output values to color intensity values of several colors (eg red, yellow, blue). These values are then made accessible to a control and control unit.
    In this way, the color intensity profile of different colors or even the entire spectrum of a printed image or even the sections of a printed image can be recorded. The measured values are then used in the manner already described in order to set the suitable position of the pressure rollers. Also for the individual colors can be done in the manner already described a contrast formation.
    Light intensity values can also be converted into coordinate systems suitable for further evaluation. The same naturally applies to the contrast values. These values derived in the last instance from intensity values and color values (wavelength / frequency) also have a characteristic course as a function of the relative position of the rollers and can be used in the manner already described.
  • Particularly advantageous is the use of the method according to the invention in flexographic printing, since in this case the thickness of the stitches has to be considered additionally. In addition, their adhesive tapes and other elements involved may have different thickness tolerances, so that it may happen that in a gentle, slightly touching employment not all parts of the plates produce printed images and only partial images arise. Therefore, the deviation between the above-mentioned geometric target value and the actual positions of the rollers involved in the printing process in the flexographic printing is particularly large.
  • The camera used is expediently a digital camera which supplies digitized images of the recorded print images.
  • For multiple printing units, the setting can be made separately for each printing unit.
  • Furthermore, a separate adjustment of the actuators for producing the parallelism of the various rollers may be provided if, due to an inclination of a roller over the length unterschledliche Andrücke arise. When flexographic printing would z. B. a separate adjustability of the actuators one side of the inking unit or the inking provide v. a . to ensure the parallelism of pressure and impression cylinder.
    For the purposes of this application, a measuring process is the observation of the course of the intensity or contrast values, while the welts involved in the printing process are adjusted to one another. If only one camera is used, it is possible to sequentially set several inking units of a machine, that is to perform a measuring operation during the setting of an inking unit.
  • However, it is also possible to perform only one measuring operation on the printing material, which has already undergone several inking units, during the setting of these inking units of a machine. This procedure leads to further time savings. This procedure may also be possible when using only one camera.
    As soon as the setting or settings are achieved which give the best match between the recorded print images and the desired shape, the values can be stored in a memory. The same naturally also applies to those setting values, resulting from the other adjustment methods according to the invention.
    In this way, these setting values can be found quickly, for example after a print interruption and after a shutdown of the printing cylinder.
  • Embodiments of the invention are explained below with reference to the drawings. In this show

  • In a printing machine frame, of which only the side plate 1 and 2 are shown schematically, a counter-pressure roller 3 provided with a drive is mounted in the usual way. The side parts 1, 2 carry a printing unit console 4, on the guides in not shown, the bearing blocks 5 and 6 of a pressure roller 7 and an anilox roller 8 slidably guided in the direction of the double arrows A and B. The mutually arranged bearing blocks 5, 6 are movable by individually controllable servo motors M1 to M4, in the catfish that each roller 7, 8 can be moved by itself and both in a fixed position to each other are moved together.
  • The printing machine frame 1, 2 is provided with further inking consoles, not shown, on which printing and anilox rollers 8 are moved in a corresponding manner, with only the single counterpressure roller 3 being provided for all printing cylinders.
  • The flexographic printing machine according to the invention can in principle be designed in the same way as in the case of its mechanical construction DE 29 41 521 A 1 . DE 37 42 129 A 1 and DE 40 01 735 A 1 described flexographic printing machines.
  • The anilox roller 8 is provided with a conventional inking device, which preferably consists of a known color camera.
  • The pressure roller 7 is provided with printing on the web 17 Kilschees 9. In this case, a diamond pattern, which is easy to represent in the figure, is printed. By hired to the platen roller 3 pressure roller 7, the running on the platen 3 in the direction of arrows C and D paper web 17 is printed with a printed image 10, which is shown for the sake of simplicity in the form of squares. This print image 10 is recorded in the detection area 11 by the camera K, which feeds successively recorded images via the line 12 to the computer-equipped control unit 13. In the control unit 13 data are entered via a special input device 14, which relate to the diameter of the pressure roller 7 and the thickness of the worn therefrom 9 clichés.
  • Via a further input unit 15, for example in the form of data stored on a CD, the desired form of the print image 10 to be printed is entered into the control and regulation unit 13. In the control and regulation unit 13, for example, in one embodiment, the printed images taken by the camera K are compared with the desired form of the printed image entered via the input unit 15, and the control and regulating unit 13 sends signals to an adjusting device 16 via lines according to the signals generated by the control unit 13, the servo motors M1 to M4 of the printing and anilox roller 7, 8 controls.
  • Once the pressure roller 7 has been adjusted to a position that produces the best quality printed images, the settings are stored in a memory of the control unit, so that, if necessary, the optimal position of the printing and anilox rollers 7, 8 can be found again ,
  • In the in FIG. 2 illustrated embodiments is shown in which way or order the three rollers involved a flexographic printing machine can be employed against each other. In other printing processes, such as gravure printing, a representation of the relative roll position setting is not necessary because only two rolls are involved in gravure printing in the printing process.
    FIG. 2 is constructed in matrix form. The columns denoted by the capital letters A to C contain Ausführungsbelplete, while the designated by the small letters a to e lines designate process steps of the individual Ausführungsbeipiele. The printing material that runs during the printing process between the pressure 7 and counter-pressure roller 6 and which in FIG. 1 the reference numeral 17 is assigned is in FIG. 2 not shown. The individual movement of a roller 7, 8 is represented by an arrow within a roller, while an arrow passing through both rollers indicates the mutual movement of the roller packet without a change in the relative position of the rollers relative to one another.
    In particular, in the description of the FIG. 2 Often the term "overpress" is used. thats why It should be pointed out at this point that "overpressing" means a pitching or pressing of the rollers which goes beyond the exact geometrical dimensions of the rollers. By this measure, it is ensured that between the "overpressed" rollers or between the substrate, which is printed between over-pressed rollers, and one of these rollers takes place in any case a full-surface ink transfer. The "distance" by which it must be "overdriven" or the pressure that is necessary for this varies from printing process to printing process from millimeter fractions to millimeters. It is clear that in most printing processes flexible rollers, substrates or other flexible additional elements are used, which increase this distance. In this context, the clichés of flexographic printing or gravure impression are mentioned as examples.
    However, it is also worth noting that cylinders made of steel can usually be overpowered by simple means, which goes beyond the ovality of their mantle surface. This is the case in particular if the cylinders have rubberized lateral surfaces. Therefore, the mentioned overpressing can be used in various printing processes.
  • In the first embodiment A of the FIG. 2 is the line a - as in the other embodiments also - the initial state in which the three rollers involved 3, 7, 8 are not yet employed against each other.
    In method step A b, the pressure roller 7 is set against the counter-pressure roller 6 and over-pressed in the manner already described above. The individual movement of the pressure roller 7 is represented by the arrow. This ensures that all zones of the plate (when colored) transfer color to the substrate. In the process step A b, however, there is still no contact and thus no ink transfer to the pressure roller 7 and the substrate.
    The next step c of the embodiment A is in approaching the anilox roller 8 to the platen 7 until all pixels on the substrate can be seen. This circumstance is verified in the manner already described with the help of at least one camera.
    Since a permanent suppression of the set in step b to each other rollers 3 and 7 is undesirable, now carried out the process steps A d and A e.
    The process step A d shows how the two rollers 7 and 8 are moved away from the Gegendurckwalze, wherein the set relative position between the anilox roller B and the pressure roller 7 is maintained.
    As part of the process step A e, the two rollers are moved back to the counter-pressure roller until all pixels are again present on the Bedruckuckstoff, which is verified again with the help of the camera. The process is completed, the print image optimized and the actual production process can begin.
  • Also in the second embodiment B, the line a is the Ausgangszustend, in which the three rollers involved, 7, 8 are not yet employed against each other.
    In method step B b, the anilox roller 8 is set against the pressure roller 7 and over-pressed in the manner already described above. This ensures that all zones of the cliché are completely colored.
  • The next step c of Ausführungsbeipiels B consists in approaching the package of anilox roller 8 and pressure roller 7 to the platen roller 3 to all pixels on the substrate can be seen. This circumstance is verified in the manner already described with the help of at least one camera.
    Since a permanent suppression of the set in step b to each other rollers 7 and 8 is undesirable, now carried out the process steps B d and B e.
    The process step B d shows how the roller 8 is moved away from the pressure roller 7, whereby the set relative position between the pressure roller 7 and the counter-pressure roller 3 is maintained.
    In the course of process step B e, the two wafers are brought together again until all image elements are present on the printing material, which is verified again with the aid of the camera. The process is completed, the print image optimized and the actual production process can begin.
    In the third embodiment C, the pressure roller 7 and the anilox roller 8 are made common to the counter-pressure roller 3 wherein all three rollers involved 3, 7, 8 are suppressed from each other.
    In the exemplary embodiment C1, the pair of rollers consisting of printing roller 7 and anilox roller 8 are then driven together by the counterpressure roller, whereby the suppression between the rollers of the roller pair remains.
    In process step C1 d, the roller pair is adjusted to the counterpressure roller until all image elements are transferred to the printing material.
    In step C1 e, the anilox roller 8 is moved away from the pressure roller, there is at least no complete color transfer instead.
    The retraction of the anilox roller 8 to the pressure roller 7 shown in the method step C1 f takes place again until the printed image is imaged without loss of area.
  • The embodiment according to Fig. 2C2 differs in the steps c to e of the embodiment Fig. 2C1 in that in step c, the anilox roller 8 of the In overpressed position pressed against the counter-pressure roller 7 pressure roller is moved from its over-pressed position relative to the pressure roller in the direction of the arrow. Subsequently, the anilox roller 8 is brought in step d in their optimal employment of the pressure roller and in steps e and f, the common departure of pressure roller and anilox roller from the platen roller and the hiring done by the control unit in a form to the platen roller, which ensures that the print image is imaged without loss of area.
  • FIG. 3 schematically illustrates how the printed image 10, which is included in the rectangle 20, can be decomposed into different sections 18. For illustrative reasons, it was decided not to skizzleren the print image itself. In practice, it is possible to decompose a printed image 10 into thousands of sections 18.
    FIG. 4 shows the contrast curve k i of the sections 18a and 18b, which is plotted as a function of the position of the rollers relative to each other x. The resulting characteristics 19 a and 19 b are assigned to the sections 18 a and 18 b. It immediately becomes clear that both characteristics have largely the same shape. The fact that both characteristics have almost identical maxima. However, due to the fact that the contrast values were normalized in this embodiment. Such standardization may be performed, for example, with respect to average values of multiple sections 18.
    The course of the two characteristic curves is offset relative to the roll position, since the rolls involved in the printing process, clichés, etc., as already mentioned several tolerances, which in this case cause the portion 18 a "earlier" is completely printed, as the portion 18 b , In the present embodiment, the portion 18a is already completely printed when the area 21a of the characteristic 19a is reached. Both sections 19 a, b are printed when the portion 21 b of the curve 18 b is reached
    Similarly, when the ninth characteristic area 21n is reached, where n is a selected number of image portions, the setting operation of the printing rollers can be terminated.
  • However, the fact that the regions 21 of the characteristic curves 19 lie behind the second inflection point of the characteristic curves 19 in the exemplary embodiment shown does not mean that this always has to be the case. Rather, the characteristics shown have several areas, the course is so characteristic that an evaluation device can easily recognize when the characteristics 19 has reached a selected number of image sections 18 such a range. The definition of this range is therefore a measure that depends on a number of parameters (print quality to be achieved, substrate, printing process, etc.) and can be performed as needed.
    The consideration of the characteristics of FIG. 4 also makes it easier to understand that all methods according to the invention also work if the wheat involved in the printing process are initially over-pressed against one another and then the rolls are driven apart from each other (the mechanical contact nevertheless remains).
    The viewer would see in this case first in FIG. 4 shown right portion of the curves in which there is relative color saturation on the substrate 17 and the slope of the curves is low.
    In this case, the disengagement of the rollers would have to be stopped if, for a number m of sections 18, the assigned areas 21 of the characteristic curves 19 had been left out and the contrast values in these areas began to decrease more.
    This variant of the invention, in which the setting of the roller positions by moving the rollers off each other comes about and is carried out as long as the printed image is reproduced without undesirable loss of area, is covered by the main claims.
  • The computation steps necessary for the various mathematical operations for carrying out the illustrated exemplary embodiment and the computation steps for carrying out the other exemplary embodiments contained in the description and the claims can be carried out in an evaluation and arithmetic unit. This can also be contained in the control unit 13.
