Definitions

  • the invention relates to a device for zone-by-zone opto-electronic measurement of the area coverage of an offset printing plate or a printing template serving for the production of offset printing plates, the brightness distribution of which can be detected by a plurality of recording elements arranged transversely to the transport direction of the printing template and can be supplied to a circuit for generating signals for setting ink fountain keys is.
  • a prerequisite for the device specified at the outset is that the measuring zone defined by the receiving elements has the same width as the ink zone width of the printing press in which the signals derived from the brightness distribution of the original to be scanned are to be used to adjust the ink zone screws.
  • the pickups arranged transversely to the transport direction of the film to be scanned are therefore dimensioned such that the zone detected by a pickup has a width which is identical to the constructionally determined ink zone width of the printing press, in which the artwork to be scanned is to be reproduced.
  • the disadvantage of the previously known scanning devices according to the type specified at the outset is that, due to the aforementioned necessity, a scanning device must be structurally adapted to a specific printing press.
  • the invention has for its object to provide a device for zone-by-zone opto-electronic measurement of the area coverage of offset printing plates or of templates used for the production of offset printing plates, with which signals for setting ink zone screws can be generated, which can be assigned to differently wide ink zones, so that the Device is no longer tied to a single type of press.
  • the advantage of the device according to the characterizing part of claim 1 is that when using several rows of receiving elements of different widths, each of which corresponds to the ink zone widths of certain printing press types, an inexpensive construction is possible and that when scanning originals that are used in printing presses with different Color zone width are to be reproduced, only a switch from one row to another row of recording elements is required.
  • a device designed according to claim 2 has the advantage that a space-saving device construction is possible by using only a single row of receptacle elements, the summation of the measurement signals derived from the individual receptacle elements for the respective zone width automatically by the appropriate programming of a computer is possible, so that templates for different color zone widths can be measured without great effort and exchange manipulations.
  • the device designed according to claim 3, on the other hand, enables continuous adaptation to any color zone width, so that these are used particularly where printing presses of different makes and thus non-coordinated color zones are available, for which the templates to be reproduced are to be measured with a single device .
  • a film assembly intended for the production of an offset printing plate is indicated at 1, the area coverage, ie the ratio of light to dark areas, can advantageously be used to adjust the ink zone screws in the area of the ink knife of a printing press.
  • the film assembly 1 is transported between a light source 2 and a sensor 3, which are arranged in a measuring chamber provided with an input slot 4 and an output slot 5.
  • two pairs of rollers 7 and 8 arranged next to one another at a small distance are provided for the lateral limitation of the measuring chamber 6.
  • the roller pairs 7 and 8 each contain one driven transport roller 9 and a driven pressure roller 10, between which the film assembly 1 is passed and which are therefore employed to form the input slot 4 and the output slot 5 against each other.
  • the pairs of rollers 7 and 8 advantageously take over the insertion and further transport of the film assembly 1 as well as shielding the measuring chamber 6 against laterally penetrating scattered light.
  • a speed-controlled motor 11 can be used to drive the transport rollers 9 in order to ensure a constant transport speed.
  • a common motor 11 is provided for the transport rollers 9 of both pairs of rollers 7 and 8, which can be connected via a belt 12 to the driven transport rollers 9 of both pairs 7 and 8.
  • the non-driven rollers 10 of the roller pairs 7 and 8 can adapt themselves to the set transport speed. In practice, a transport speed of one to three, but preferably two meters per minute is expedient.
  • a guide plate 13 leading up to the roller surface can expediently be arranged, the bearing surface of which is aligned with the input and output slots 4 and 5 for receiving the film assembly.
  • This ensures a simple way of guiding the film assembly 1, in particular the beginnings and ends, from the input slot 4 to the output slot 5 and also shielding the measuring chamber 6 against dirt or light penetrating from the drive.
  • a removable cover 14 is provided in the area of the transport rollers 9.
  • the light source 2 consists, for example, of a commercially available tubular lamp and is mounted on the cover 14 by means of a holder 15.
  • the width of the receiving elements 16 and thus of the transducer 3 is small in relation to their length.
  • the small light-sensitive recording surface achieved in this way can thus advantageously be uniformly illuminated without any effort.
  • Commercial optical elements, such as so-called fiber optics are suitable as receiving elements 16.
  • the receiving elements 16 are embedded in narrow recesses 17 of the guide plate 13.
  • the light flux emitted by the light source 2, passing through the film 1 and detected by the receiving elements 16 is, as shown in FIG. 3, fed to the individual receiving elements 16 downstream photo elements 18.
  • the photo elements 18 generate an electrical signal proportional to the incoming light intensity, which is integrated in integrators 19 or in a microprocessor over the entire length of the film.
  • the output signal of an integrator 19 thus corresponds exactly to the area coverage of the assigned zone of the film 1, which, as already mentioned, is identical in width to the ink zone width of a printing press.
  • This output signal can optionally be displayed visually with prior storage in a memory 20 on a display panel 21 and / or processed via a computer 22, preferably a microprocessor, and stored in a memory 23, after which it is used to adjust the ink fountain keys in a printing press at Reproduction of the measured template is available.
  • the width of the receiving elements 16, seen transversely to the transport direction of the film assembly 1, corresponds to the ink zone width of a specific printing press. If templates now have to be scanned which are to be reproduced in printing presses with a different ink zone width, then according to one embodiment of the invention the device described above is switched over to a second pickup 3 '.
  • the pickup 3 ' has receiving elements 16', the width of which deviates from that of the receiving elements 16 and are matched to the ink zone width of this other printing press.
  • the light components detected by the receiving elements 16 ' are converted into proportional electrical signals in photo elements 18' which can be supplied to the electrical circuits 19 to 21 instead of the signals generated by the photo elements 18.
  • the sensor 3 or the sensor 3 ' can be used depending on the ink zone width of the printing presses. It is understood that this embodiment of the invention is not limited to the use of only two rows of receiving elements 16 and 16 '.
  • the light coming from the light source 2 and passing through the film assembly 1 is detected by a multiplicity of receiving elements 24 and, after corresponding conversion into electrical signals and after integration in the individual circuits, which are not described in more detail, reaches a computer 25.
  • a multiplicity of receiving elements 24 In the exemplary embodiment according to FIG. 4, for the sake of simplicity, twelve of the receiving elements 24, 24 1 to 24 "are shown. Depending on the width of the ink zone, the printing measure used in each case The number 25 of recording elements is added up in the computer 25. In the example described here there are three receiving elements.
  • the resulting signal is used to control an ink zone screw, which influences a ink zone area in a printing press, the ink zone of which is as wide as the width of three recording elements.
  • the ink zone adjusting screws 26, 26 1 to 26 “" are symbolically indicated with the individual ink knives assigned to them.
  • the control signals for the four color zone adjusting screws 26 to 26 m shown are thus generated by combining the measured values from each of three of the receiving elements 24 to 24 ". It is essential in the embodiment according to FIG.
  • the measuring zone width of a receiving element 24 is common to all of the color zone widths If, for example, printing presses are used whose zone widths are 40 mm, 35 mm and 30 mm, then a receiving element 24 with a measuring zone width of 5 mm must be used, in which case eight receiving elements 24 are used for a color zone width of 40 mm a color zone width of 35 mm, seven recording elements 24 and, with a color zone width of 30 mm, six recording elements 24 combined or the measurement signals derived from them summed up in a computer 25, preferably a microprocessor, and processed to control the respective color zone screws.
  • a memory which is no longer shown in FIG. 4, can be used, in which the signals generated by the computer 25 are stored and which can be read in a known manner as required when reproducing the measured template for controlling the ink fountain keys.
  • a scissor grid 29 or a functionally equivalent element is arranged between the side walls 27 and 28 and is fixed on the left side wall 27 and its length can be changed on the right side wall 28.
  • a threaded spindle 30 rotatably mounted in the side wall 28 can be used, upon rotation of which a guide nut 31 arranged on it, which is connected to the right end of the scissor lattice 29, is displaced in the left-right direction.
  • Receiving elements 32 are fastened on each leg of the scissor grid 29 running parallel to one another, with which certain measuring zone regions can be detected.
  • the scissor grid is arranged transversely to the transport direction of a template to be measured.
  • the measuring zone area which can be detected by a recording element 32 to 32 "can be matched to the width of the color zone of the machine used for the reproduction of a template to be measured, since the projection of the recording elements 32 onto the measuring line also Can be infinitely varied with the aid of the spindle 30.
  • the device can be adapted to the ink zone width of a wide variety of printing presses by a suitable inclination of the scissor grid 29.
  • the incident light method e.g. B. for scanning printing plates.
