Definitions

  • the invention relates to a color test device with a printing roller, a color application interacting with its surface and a strip of goods to be printed, which is quickly detachably attached to a base with a flat surface on which the printing roller rolls.
  • the device according to the invention is also intended to enable the testing of flexographic printing inks, specifically for doctor blade flexographic printing, and is suitable for the use of densitometers for checking the color densities of primary colors.
  • the printing roller is a gravure roller and the ink application is a squeegee attached to the upper side of the printing roller, which are mounted on a carriage which has a handle for its movement and which has longitudinal grooves in the base Intervene on both sides with two spaced rollers in front of each other, arranged at the lower edge of the slide.
  • the rotogravure roller can advantageously have a number of fields rolling in succession, which have a different engraving.
  • the bearings of the rotogravure roller and thus these can advantageously be movable in a plane perpendicular to the plane of the strip, and the bearings of the rotogravure roller are springed in the direction of the plane of the strip to be printed , crowded.
  • the simplicity enables a low price and a corresponding spread of such a device would provide a basis for the application of a standardization of the color density or color.
  • the device according to the invention is suitable for printing on all so-called intaglio carriers, that is, paper and all types of film.
  • the device for color or density testing consists of an intaglio roller 1, which runs on a flat surface 6.
  • the strip 5 to be printed is arranged on the surface of the base 6 and below the gravure roller 1, which is held on both sides by means of clamping brackets 10 and can be easily exchanged or clamped and unclamped due to its mobility.
  • the clamping bracket 10 pivot about a pivot pin 12 and are supported at their end remote from the area to be printed by springs 11, so that they open by finger pressure against the force of the spring 11 and the ends of the strip can be inserted.
  • the springs 11 then hold the strip 5 to be printed tight until a reopening of the bracket 10 after the test print has taken place.
  • the gravure roller 1 has bearings 7 which are pressed by means of springs 8 under adjustable pressure onto the strip 5 to be printed.
  • the springs 8 are held by brackets 20, which in turn can be opened or closed by a quick-release fastener.
  • the quick release has a pivot lever 9 on which is rotatable about a pivot pin 14 and is held in its closed position by a spring 13. If the lever 9 is pivoted by manual action, its hook end is released from a bolt 15 and the bracket 20 can open. To close the bracket 20, they are simply pressed down and the lever 9 engages automatically under the force of the spring 13 with its hook end on the bolt 15.
  • the ink application to the printing roller 1 takes place directly via a doctor blade 2, on the surface of which the ink to be tested is applied.
  • the doctor blade 2 can be pivoted via a pivot pin 3 at the end of the doctor blade guide remote from the roller, the angle of the doctor blade relative to the plane of movement of the printing roller 1 being adjustable by means of a locking nut (knurled screw).
  • a locking nut press-fite screw
  • the doctor blade 2 In order to prevent the ink from flowing down from the surface of the doctor blade 2, it can have lateral webs whose ends near the roller are shaped in accordance with the surface curvature of the roller and bear against it.
  • the gravure roller as well as the doctor blade and the associated parts are arranged on a carriage 16 which can be moved in one plane along the base 6 by means of a handle 17.
  • the base 6 has grooves 18 on both sides, in which two rollers 19 of the carriage 16 engage on one side in order to ensure that the pressure is received in addition to reliable guiding.
  • the rollers 19 are spaced apart from one another along the grooves 18 in order to prevent the carriage 16 from pivoting.
  • the pressure force itself can be varied as desired by choosing the stiffness of the springs 8.
  • the rollers 19 rest on the upper edges of the grooves 18. It is achieved in that defined pressing forces become effective which would not be adjustable by simply rolling them over by hand.
  • ink by means of an electronically engraved roller, a conventionally etched roller or an autotypically etched roller without having to change the rest of the construction of the device according to the invention.
