Definitions

  • the invention relates to the field of electronic reproduction technology and relates to a device for tempering the exposure drum in an imagesetter for recording artwork on printing plates.
  • print templates are created for printed pages that contain all elements to be printed such as texts, graphics and images.
  • a separate print template is created for each printing ink contains all elements that are printed in the respective color.
  • the printing inks cyan, magenta, yellow and black (CMYK).
  • CMLK magenta, yellow and black
  • the printing templates separated according to printing inks are also called color separations.
  • the artwork is usually rasterized and with an imagesetter exposed on films, with which printing plates for printing large runs getting produced. Alternatively, the artwork can be used in special exposure devices can also be exposed immediately on printing plates or they will be directly transferred as digital data to a digital printing machine. There will be the print template data then, for example, with one integrated into the printing press Exposure unit exposed on printing plates before immediately afterwards the print run begins.
  • the print templates are electronic reproduced. Images are scanned in a color scanner and in shape of digital data stored. Texts are created using word processing programs generates and graphics with drawing programs. With a layout program the image, text and graphic elements are put together on a printed page. After separation into the printing inks, the print templates are then digital Form before.
  • Postscript and PDF Portable Document Format
  • the Postscript or PDF data are before the recording of the artwork in a raster image processor (RIP) in a first step converted into color separation values for the CMYK color separations. This creates four color separation values as tonal values in the Range of values from 0 to 100%.
  • the color separation values are a measure of the color densities, with which the four inks cyan, magenta, yellow and black printed on the substrate. In special cases where more than four Colors is printed (spot colors), each pixel is characterized by so many color separation values described how printing inks exist.
  • the color separation values can e.g. stored with 8 bits per pixel and printing ink as data value, which divides the value range from 0% to 100% into 256 tone levels.
  • the data of several printed pages are combined with the data of other elements such as Registration marks, cut marks and fold marks as well as print control fields Printing templates summarized for a printing sheet. This sheet data are also provided as color separation values (CMYK).
  • Different tonal values of a color separation to be reproduced can be in printing only by means of a surface modulation of the applied printing inks, i.e. through a grid.
  • the surface modulation of the printing inks can be done, for example, according to a dot screening method in which the different tonal value levels of the color separation data in halftone dots different Size to be converted using a regular grid periodically repeating grid cells are arranged.
  • the color separations on a printing plate are the halftone dots in the individual Grid cells composed of exposure points that by one Order of magnitude smaller than the halftone dots.
  • a typical resolution of the Exposure points is, for example, 1000 exposure points per centimeter, i.e. an exposure point has the dimensions 10 ⁇ m ⁇ 10 ⁇ m.
  • Implementation of the Color separation values in halftone dots are done in a second step further processing of the color separation data in the raster image processor, whereby the color separation data in high-resolution binary values with only two brightness values (exposed or unexposed) that are converted to the pattern of the modulated grid of points.
  • the artwork data each color separation is described in the form of a high-resolution raster bitmap, which contains one bit for each of the exposure points on the printing surface, that indicates whether this exposure point is to be exposed or not.
  • Exposure of artwork and printing forms are used, for example a laser beam generated by a laser diode by optical means shaped and focused on the recording material and by means of a deflection system Point and line distracted over the recording material. It are also recording devices used to increase exposure speed generate a bundle of laser beams, e.g. with a separate laser diode for each laser beam, and several each time the recording material is scanned Expose image lines of the printing form at the same time.
  • the printing forms can on Film material are exposed so that so-called color separation films are formed, which are then produced using a photographic copying process of printing plates.
  • the printing plates themselves can be used in one Platesetters or directly exposed in a digital printing machine, in which a unit for plate exposure is integrated.
  • the recording material can be on a drum (outer drum imagesetter), in a cylindrical one Trough (inner drum imagesetter) or on a flat surface (flat bed imagesetter).
  • the material to be exposed is in the form of Films or printing plates mounted on a rotating drum. While the drum rotates, an exposure head becomes axial at a relatively short distance moved along the drum. The exposure head focuses on one or more Laser beams onto the drum surface, which the drum surface in Paint over the shape of a narrow helix. This way everyone will Drum rotation one or more image lines on the recording material exposed.
  • the punch holes in the pressure plates are used for correct positioning when clamping the Printing plates on the plate cylinder in the printing press.
  • the location of the exposure area and the position of the punch holes are related to a leading edge and determines one or both side edges of the recording material.
  • the edges of the recording material are defined by means of contact pins Position on the exposure drum brought or their position is after the stretching of the material measured. Then the starting point of the exposure depending on the position of the edges so that the reference to the edges of the recording material is always the same.
  • Printing plates have in generally a support material made of aluminum with a thickness in the range of 0.1 to 0.3 mm. They change their dimensions due to the temperature Length extension of approx. 24 ⁇ m per degree Celsius and per meter edge length. In As a rule, the printing plates become immediate for all color separations of a printing sheet recorded successively in the same platesetter, so that the fluctuations in temperature from one record to the next are so small that they don't matter. But it can also happen that the color separations of a printing sheet on different platesetters recorded in different temperature-controlled rooms, or they are exposed at different times.
  • Patent application DE 101 37 166 A1 describes a method for temperature control of the printing plates suggested during printing to deal with this caused the expansion of the printing plates to the geometric distortions compensate for the substrate when passing through several printing units experienced by dampening solution absorption and pressure compression. For this, e.g. With Temperature control elements, which are incorporated into the outer surface of the plate cylinder are impressed on the pressure plate in the circumferential direction adjustable temperature profile. Alternatively, the printing plate with the inking rollers and the Fountain solution roller tempered to different jacket temperatures are adjustable.
  • the known devices and methods for compensation or reduction the temperature-dependent changes in the dimensions of printing plates exposure is structurally complex and associated with high costs.
  • the task is solved by a device with which a tempered during the exposure Liquid is passed through the exposure drum, so that the outer surface the exposure drum and the printing plate stretched thereon independently assumes a defined temperature from the outside temperature.
  • Fig. 1 shows the basic structure of an outer drum imagesetter.

  • On the exposure drum 1 is an unexposed, rectangular pressure plate 3 stretched, the front edge 4, a left side edge 5, has a right side edge 6 and a rear edge 7.
  • the pressure plate 3 is stretched so that its front edge 4 touches 8 pins 8 are firmly connected to the exposure drum 1 and over the surface of the Project exposure drum 1.
  • a terminal block 9 presses the front edge 4 also firmly on the surface of the exposure drum 1 and thereby fixed the front edge 4 of the pressure plate 3.
  • the pressure plate 3 is flat by means of a in Fig. 2, not shown, vacuum device which the pressure plate 3 through holes in of the drum surface, held on the drum surface so that the Pressure plate 3 is not replaced by the centrifugal forces during rotation. additionally the rear edge 7 of the pressure plate 3 is fixed with clamping pieces 10.
  • An exposure head 11 is axially at a relatively short distance on the exposure drum 1 moves along while the exposure drum 1 rotates.
  • the Exposure head 11 focuses one or more laser beams 12 on the Drum surface, which the drum surface in the form of narrow helixes sweep. In this way, one with each drum revolution or several image lines in the circumferential direction x on the recording material exposed.
  • the exposure head 11 is moved in the feed direction y by means of a feed spindle 13 moves, with which it is positively connected and with one Feed drive 14 is rotated.
  • the artwork 15 to be exposed on the printing plate 3 covers only a part of the total available recording area.
  • the tolerance of the remaining shift between the color separations or the remaining one different dimensions should be less than 25 ⁇ m.
  • the always the same reference to the front edge is ensured, for example, by the contact pins 8, to which the front edge 4 of the printing plate 3 before exposure at Clamping on the exposure drum 1 is applied.
  • the reference to one of the lateral edges of the pressure plate 3 is ensured by a measuring device (not shown in Fig.
  • Printing plates with an aluminum support have a temperature-related linear expansion by approx. 24 ⁇ m per degree Celsius and per meter edge length. Despite the exact reference of the artwork 15 to be exposed to the plate edges can therefore accept the maximum tolerance of 25 ⁇ m for a registration error be exceeded significantly when the print templates 15 of the color separations be exposed at different temperatures and the printing plates 3 then later to a uniform temperature when clamping in the printing press to be brought.
