Definitions

  • the invention relates to a method of mounting printing plates on a plurality of cylinders for multi-colour printing.
  • a rotary printing press When a rotary printing press is prepared for a multi-colour print job, one or more printing plates which define a colour separation image are mounted on a printing cylinder in a corresponding colour deck of the printing press.
  • the print substrate e. g. a web
  • the term "cylinder” shall encompass both, printings cylinders and so-called sleeves that are to be mounted on mandrels that remain in the printing press.
  • the printing plates typically have dimensions corresponding to the size of an entire printing format, i.e. the image that is formed in a complete revolution of the printing cylinders.
  • Each printing plate has two reference structures, e. g. microdots, formed on the opposite sides of the printing plate and in the same longitudinal position.
  • the printing plate is secured to the peripheral surface of the printing cylinder by means of adhesive tape or a re-useable adhesive layer, while the printing cylinder is supported in a mounter.
  • the mounter has two cameras each of which defines a target position for one of the microdots and captures an enlarged image of the microdot and its surroundings while the printing plate is mounted on the cylinder. By observing the images captured by the two cameras, the printing plate is manually adjusted such that each microdot is aligned with a target mark, e. g. a hair-cross in the image of the corresponding camera.
  • the camera positions in the mounter may be left unchanged while the printing plates are mounted on the various cylinders. This assures that the positional relation between the printing plate and the cylinder will be the same for all cylinders.
  • EP 1 916 102 B1 discloses a printing system, wherein each printing cylinder has a reference mark, and the mounter includes a sensor which can detect this reference mark and can measure the longitudinal and angular offset of the reference mark relative to the cameras in the mounter.
  • the mounter includes a sensor which can detect this reference mark and can measure the longitudinal and angular offset of the reference mark relative to the cameras in the mounter.
  • the printing plates will have a considerable size, and inevitable size variations in the printing plate production process may lead to significant deviations in the distance between the two microdots on the printing plate. This limits the positional accuracy with which the printing plates can be mounted on the cylinders.
  • this is possible only on condition that the image to be printed is divided into distinct areas, e. g. several frames which all include the same image contents, as is frequently the case in the packaging industry. Otherwise, butting seams between the different plates would be visible in the printed image.
  • EP 1 990 193 A2 discloses a method and a mounter according to the preamble of claims 1 and 9.
  • US 4 743 324 A and US 5850 789 A describe methods in which the printing plates are positioned on a flat table and are the transferred onto the cylinder surface.
  • the invention proposes a method and a mounter as defined in claims 1 and 9.
  • the positions of the reference structures on printing plates for different colours may be selected independently from one another.
  • a positional relationship between the plates is established only by the coordinate positions of the reference structures in a common coordinate system.
  • the number of printing plates to be mounted on the same cylinder or, more generally, to be used for the same colour may be selected differently for each colour, and the printing plates may have different sizes.
  • the invention has the advantage that the number and the sizes of the printing plates for each colour may be optimized depending upon the nature of the respective colour separation image. For example, when a certain colour occurs only in a relatively small portion of the printing format, the size of the corresponding printing plate may be reduced so that it just covers the necessary portion of the image. This significantly reduces the costs for the printing plates and for the adhesive tape.
  • each cylinder has a reference mark being detected by a sensor in the mounter.
  • the reference mark may be formed on the cylinder when the cylinder has been installed in the mounter, and, instead of measuring an offset, the reference mark is placed in a position that has a well defined relation to the coordinate positions of the reference structures on the plates.
  • the reference structures on the printing plates are not limited to microdots or any other structures that are provided on the printing plates in addition to the printing pattern for the image to be printed. Rather, the invention includes the possibility that any suitable structures in the printing pattern are defined as reference structures, and a coordinate position of the reference structure will then be defined as a coordinate position of a reference image that shows the selected structure in the printing pattern at an enlarged scale. This reference image will then be superposed on a display which also shows the image captured by the camera, and the adjustment of the printing plate is achieved by making the structure in the printing pattern, as captured by the camera, coincide with the reference image.
  • Fig. 1 illustrates an example of a printing format 10, i.e. an image that is printed per complete revolution of printing cylinders in a rotary printing press.
  • the printing format 10 is composed of four frames 12 with identical image contents.
  • the image is a colour image with five colour separations in yellow, red, green, blue and black and is accordingly printed with printing plates on five printing cylinders of the printing press.
  • the yellow colour separation forms the background a rectangular region that covers almost the entire area of the frame 12.
  • the red colour separation is composed of a triangle 16 in the upper left corner of the frame and a square 18 in the left bottom part of the frame.
  • the green colour separation is a circle 20 in the center of the frame, party overlapped by the red square 18, and the blue colour separation is a triangle that overlaps the green circle 20.
  • the black colour separation is formed by bar code 24 in the bottom right corner of the frame 12.
  • the printing format 10 may be available in the form of an image file in any suitable image format such as PDF and may be displayed on an interactive monitor screen, so that an operator may define the sizes and shapes of the printing plates for the different colour separations.
  • Fig. 2 shows the printing format 10 in dot-dashed lines and, superposed therewith, the contours of printing plates 26, 28 and 30 for the yellow and red colour separations, as defined by the operator.
  • the printing plate 26 for the yellow colour separation covers the entire printing format 10, as it is conventional in the art.
  • the printing plate 26 is provided with two microdots 32 on the left and right margins of the format 10.
  • the coordinate positions of the microdots 32 are defined in an X-Y-coordinate system in which the X-axis corresponds to the transverse direction of a web on which the image is to be printed, and the Y-axis corresponds to running direction of the web.
  • the two microdots 32 have the same Y-coordinate.
  • each printing plate covers two frames in Y-direction but has only a width of approximately on half of the frame in X-direction, so that the material needed for forming the two printing plates 28, 30 is less than half of the material needed for the printing plate 26.
  • Each of the printing plates 28, 30 has two microdots 32 which, in this example, have the same Y-coordinate as the microdots of the printing plate 26.
  • microdots 32' may be provided in diagonally opposite corners of the printing plates 28, 30. This has the advantage that the accuracy in positioning the printing plates on the printing cylinder is improved, because the distance between the microdots is larger and especially the positions of the top and bottom ends of the printing plates can be defined with higher accuracy.
  • a single printing plate 34 has been defined for the four circles 20 forming the green colour separation.
  • the dimensions of the printing plate 34 can be smaller than the those of the printing plate 26 for the yellow colour separation, so that plate material can be saved.
  • the printing plate 34 has two microdots 32 located at the same Y-coordinate as the those of the printing plates 26, 28 and 30.
  • Fig. 4 shows the layout of printing plates 36, 38 for the blue and the black colour separations. As many as four separate printing plates have been defined for each colour, with the result that the printing plates can be made extremely small.
  • Each of the printing plates 36, 38 has two microdots 32 which, however, need to have Y-coordinates different from those of the microdots of the printing plates 26, 28, 30 and 34 for the other colour separations. Yet, the printing plates 36 and also the printing plates 38 form pairs in which the microdots have the same Y-coordinates.
  • one of the microdots falls within the blue triangle 22.
  • This microdot is an inverse microdot, i.e. a white dot on the blue background. In flexographic printing, for example, this means that a small depression is formed in the printing pattern that defines the solid blue area. In general, such inverse dots are more difficult to see than normal "positive" dots.
  • Fig. 5 is a table which shows for each colour separation the number of plates that have been defined for the respective colour separation, an identification (Plate-No.) for the individual plates that belong to the same colour, and the X- and Y-coordinates of the two microdots of each printing plate.
  • a data file with the contents of the table shown in Fig. 5 is sent from the pre-press stage to the plate production stage where it is used to prepare the plates with the respective printing patterns and the microdots thereon.
  • the data file may also specify the shapes and positions of the different printing plates in the printing format. Although all the printing plates have a rectangular shape in the example shown, it would generally also be possible to use printing plates with non-rectangular shapes.
  • Fig. 6 shows a mounter 40 that is used for mounting the printing plates on printing cylinders 42.
  • the mounter has a base 44 with releasable bearings 46, 48 for rotatably supporting the printing cylinder 42.
  • a drive motor 50 is provided for rotating the printing cylinder.
  • a high resolution displacement sensor 52 permits to control and keep track of the angular movements of the printing cylinder 42.
  • a guide rail 54 is rigidly mounted on the base 44 and carries two camera carriages 56 each of which is equipped with a camera 58 that faces the peripheral surface of the printing cylinder 42.
  • the camera carriages 56 can be driven to move along the guide rail 54, and include displacement sensors for detecting the positions of the camera carriages with high resolution.
  • a magnetic reference mark 60 is embedded in the peripheral surface of the printing cylinder 42, and a sensor 62 (e.g. a Hall sensor) is rigidly mounted on the bed 44 for precisely measuring the position of the reference mark 60 in two dimensions.
  • a sensor 62 e.g. a Hall sensor
  • the drive motor 50 and the displacement sensor 52 for the printing cylinder 42, the cameras 58 and the drive units and displacement sensors of the camera carriages 56, and the sensor 62 are connected to an electronic control unit 66.
  • the sensor 62 detects the position of the reference mark 60 in both, the axial direction of the printing cylinder 42 and the direction normal to the plane of the drawing in Fig. 6 .
  • the axial direction of the printing cylinder 42 corresponds to the direction of the X-axis in Fig. 2
  • the direction normal to the plane of the drawing in Fig. 6 corresponds to the Y-direction in Fig. 2 .
  • the offsets between the reference mark 60 and the sensor 62 in these directions are measured with the sensor 62 and stored in the control unit 66. These offsets serve for defining zero-positions for the X- and Y-coordinates.
  • the printing plate 28 is placed on the peripheral surface of the printing cylinder 42 with adhesive tape intervening between the plate and the cylinder, but is not yet finally fixed in position, so that positional adjustments are still possible.
  • the contents of the data file shown in Fig. 5 are loaded into the control unit 66 and stored therein.
  • the camera carriages 56 are driven to move the cameras 58 into the positions specified by the X-coordinates of the microdots 32. If the sensor 62 has detected an offset in X-direction, the camera positions are corrected by this offset, so that the reference or zero position for the X-coordinates of the microdots 62 is not formed by the sensor 62 but by the reference mark 60 on the printing cylinder.
  • Each camera 58 captures an enlarged image of a portion of the surface of the printing plate 28 that includes the respective microdot 32. Both images are shown in a display image 68, as has been illustrated in Fig. 7 .
  • a target mark 70 e.g. a hair-cross is superposed on the image of each camera. These target marks correspond exactly to the intended X-coordinates for the microdots 32.
  • the printing plate 28 is manually adjusted until the microdots 32 are exactly aligned with the centers of the target marks 70. In the example shown in Fig. 7 , the printing plate has to be shifted to the left and slightly rotated clockwise. When both microdots 32 have been optimally centered onto the target marks 70, the printing plate 28 is finally fixed in position.
  • the camera carriages 56 are driven to move the cameras into the target positions for the next printing plate (30) that is to be mounted on the same cylinder 42. Since the microdots 32 of both printing plates 28 and 30 have identical Y-positions, as shown in Fig. 2 , it is not necessary to change the angular position of the printing cylinder 42.
  • the printing cylinder 42 is removed from the mounter 40, and the next printing cylinder is installed in the mounter and the necessary printing plates are mounted thereon by repeating, for each printing plate, the procedure that has been described above.
  • a slightly modified procedure is necessary for a printing cylinder, for which the microdots 32 of the printing plates have different Y-coordinates. In the present example, this would be the case for the printing plates 36 ( Fig. 4 ) for the blue colour separation, and also for the printing plates 38 for the black colour separation.
  • the printing cylinder has to be rotated into the position for mounting the remaining two printing plates 36.
  • the difference between the Y-coordinates of the microdots 32 of the first two plates and the Y-coordinates of the microdots of the second two plates is transformed into an angular displacement of the printing cylinder, and the drive motor 50 is controlled to rotate the printing cylinder by a suitable angle, the angular displacement being controlled with high resolution by the displacement sensor 52.
  • the drive motor 50 is controlled to rotate the printing cylinder by a suitable angle, the angular displacement being controlled with high resolution by the displacement sensor 52.
  • the cylinders can be mounted in the printing press. Then, the positions of the reference marks 60 are detected in the printing press, and the side registers are adjusted so that the reference marks of all printing cylinders are exactly aligned with one another. Since the reference marks 60 serve as a reference position for the microdots 32 of all the printing plates, it is assured that all printing plates have exactly the correct lateral or X-position in the printing press.
  • the angular positions of the printing cylinders in the printing press are also adjusted by reference to their reference marks 60.
  • the sensor 62 may have detected different offsets in Y-direction for the different printing cylinders.
  • the angular positions of the printing cylinders in the printing press are therefore corrected by the measured offsets, so that all printing plates for all colours will also have the correct longitudinal register.
  • the cameras 58 of the mounter 40 are adjustable in circumferential direction of the printing cylinder independently of one another. This will allow a configuration of the microdots as illustrated by the microdots 32' in Fig. 2 , i.e. a configuration where two microdots of the same printing plate 28 have different Y-coordinates. Then, the two cameras 58 will be rotated to the angular positions that correspond to these Y-coordinates, so that both microdots 32' can be observed and displayed simultaneously in the display image 68.
  • Figs. 8 and 9 illustrate an embodiment where the printing plates (e.g. the printing plate 28) does not have any microdots at all. Instead, certain features of the image to be printed are used directly as reference structures 72, 74. In the example shown, these features are the top left corner of the triangle 16 and the lowermost corner of the square 18.
  • the data file to be transmitted to the control unit 16 includes enlarged copies of these image features, and these copies are presented as reference images 72', 74' in the display image 68, as has been shown in Fig. 9 .
  • the data file will also include a coordinate position for each reference image, e. g. the coordinates of the image centre, and the cameras 58 are adjusted to these coordinate positions.
