Definitions

  • the invention relates to a device for evaluating printing originals, in particular for zone-by-zone color control of printing presses, with a screen device and an optical device directed towards the printing original.
  • a display device for color control systems for printing presses in which color density values, setting and tolerance values and target and actual values are displayed on a display device.
  • the values to be displayed are either entered via a color control panel (keyboard) or recorded by measuring sensors arranged at color zones.
  • the image scanned on a print template is superimposed on these values shown on the screen. This enables a clear assignment of display values to the print image and the printer can record the print image and display values at a glance.
  • a disadvantage of this known device is that complex recording electronics (video camera) are required to capture the complete print image, which then also has to be implemented by further electronics such as image converter, image mixer, character generator, etc.
  • the object of the present invention is to provide a device with which information can be transferred in an individual manner from a print template to a data display device (screen) or to a memory or vice versa in a simple manner.
  • This object is achieved by applying the features of the characterizing parts of claims 1, 6 and 9. Further developments of the invention result from the subclaims and from the description in conjunction with the drawing, which schematically represents an exemplary embodiment.
  • a print template 2 bearing an image 3 is expediently placed on a control panel 1.
  • a control panel 1 For zone (color) control two rows of buttons are provided on the control panel 1, of which only one (minus) button 5 and one (plus) button 6 are shown.
  • an optical marking (8 ') is preferably shown in the form of a cross, or a bar or a point.
  • the screen 7 is part of a screen device 9 arranged on or in the vicinity of the control panel 1.
  • a preferably similar optical marking 8 is also produced on the printing template 2, specifically by a light source 10.
  • the light source 10 preferably generates coherent light and therefore consists of a laser.
  • the light source 10 is attached to a bracket 11, which should allow pivoting in two directions, so that the light source 10 can be directed to any point of the artwork 2.
  • the mark 8 in the form of a cross can therefore be generated at any point on the print template.
  • the pivoting information is activated or supplied via a line 12 which is connected to a control unit 13.
  • the latter can consist of a programmable computer and possibly other electronic components.
  • the device shown has a manually operable pointer control 14, for example in the form of a rollerball, a joystick, a mouse, a graphics tablet or cursor keys. It is essential that the pointer control 14 can be used to generate coordinate signals, usually XY signals, by means of which the control unit 13 can be used to pivot the light source 10 in the two-dimensional coordinate system, so that the light source 10 is directed at any point on the print template 2 can be.
  • the pointer controller 14 is connected to the control unit 13 via a line 15 and, if necessary, control or control information can be provided via a line 16 the control unit 13 can be applied to the pointer control 14.
  • the light source 10 is arranged above the control panel 1 or the print template 2, so that the optical pointer in the form of the marking 8 is generated by the incident light method.
  • the light beam 18 generated by the light source 10 is then not projected onto the artwork from the front but from the rear.
  • the mark 8 on the print template 2 can thus be brought to any desired location by corresponding movement of the pointer control 14. In particularly simple cases, it may also be sufficient to move the marking 8 only in the horizontal direction, as a result of which the pivoting in the second (Y) direction and the control means required for this are eliminated.
  • the mark 8 'on the screen 7 is also shifted by the same amount and in the same direction via the control unit 13, but usually with a reduced scale, since the screen 7 is smaller than the print template 2 is.
  • information can be displayed on the screen 7 in the form of vertical lines which interpret the positions, for example of color slides or the color meter sections in individual color zones.
  • ink slides 20 are indicated schematically on an ink fountain roller 19. They are each adjusted via ink zone adjusting devices 21 in order to regulate the zone-by-zone ink requirement.
  • the ink zone adjusting devices 21 can be controlled via a line 22 and a changeover switch 23, which via Lines 24 and 25 are connected to the keyboard 5, 6 and to the display device 9.
  • the color slides 20 can be controlled either from the color keyboard 6, 5 or from the screen device or via the control unit 13, for which purpose the line or lines indicated at 26 are also provided.
  • a position transfer from an original, for example a print template, to an abstract model, for example on a data display device, and vice versa is possible.
  • the overriding principle of the invention is therefore that with the aid of an input unit, e.g. the pointer control 14, a pointer 8 is moved on the print template 2.
  • the current position of the pointer 8 is transmitted via a control unit 13 and can be made visible on a screen 7.
  • any positions can be transferred in a simple manner from the original to graphics from visual display devices and vice versa.
  • control unit 13 being equipped with a memory 27 for this purpose.
  • Setting information can be stored in the memory 27 be stored for the light beam 18 or for the light source 10, specifically preferably XY setting values, with the aid of which the light source 10 or the light beam 18 can be directed to any point of a printed copy or a print template 2.
  • user guidance for example for the printer, is advantageously possible, in such a way that the light beam 18 is successively directed to specific positions of the original 2.
  • These positions can represent, for example, measuring points or measuring points at which the printer records color measured values with the aid of a manual densitometer in order to use these via a corresponding control for individually adjusting the color slides 20.
  • the printer can be guided from measuring point to measuring point or from register mark to register mark or from color-free areas to color-free areas etc. if their positions or coordinate values are present in the memory 27 in a corresponding sequence.
  • the device is used for entering coordinates. This can be done manually or automatically.
  • the light source 10 is based on the coordinates to be entered or stored, i.e. directed to specific positions on the artwork 2.
  • the X and Y values of the position of the light source and the deflection position of the light beam 18 are detected and stored by a signal, for example by pressing a key.
  • This can preferably be used to coordinate the measuring points, measuring marks, register marks, color-free areas, the X and Y position when the subject is shifted (position of use on the printing plate), image-important areas, areas to be controlled, the position of the measuring strip are recorded and those of areas in which corrections of the repros are required, as well as from a start to an end point in order to enable length detection (electronic folding rule).
