Definitions

  • Inkjet printing machines prints by spraying particular amount of paint material over the material which will be printed on.
  • Inkjet printing machines has two different constructions:
  • Inkjet printheads have different constructions varying by company and models. In digital inkjet printing machines, separate inkjet printheads were used for each color. Inkjet printhead producers has started to manufacture double (canal) inkjet printheads for reducing the number of printheads in the printing machines. Double (canal) inkjet printheads accept filling the canals different paint materials with different colors, and control them independently. In other words, a single printhead can be used for two paint materials of different color, instead of requiring two inkjet printheads. It can be considered that, inkjet printheads with more canals will be produced in the future. In the application, such inkjet printheads are referred as "multi-canal inkjet printheads (8)".
  • FIGURE-1 Continuous inkjet digital printing machine: Inkjet printheads (7) are placed inside the inkjet printhead groups which are lined up along the width of the machine in a way to leave no printing gap and will be steady throughout the time of printing (9). Within this system, equipment such as necessary electronics, communication system, paint material system is included.
  • FIGURE-2 Same structure as described for the continuous inkjet digital printing machine FIGURE-1, except the difference: Multi-canal inkjet printheads (8) are placed inside the inkjet printhead groups which are lined up along the width of the machine in a way to leave no printing gap and will be steady throughout the time of printing (9). Within this system, equipment for multi-canal inkjet printheads (8) such as necessary electronics, communication system, paint material system is included.
  • FIGURE-3 The bird's eye view of continuous inkjet digital printing machine in FIGURE-1.
  • FIGURE-4 The bird's eye view of continuous inkjet digital printing machine in FIGURE-2.
  • Belt (1) provides movement to the will-be-printed material by making it glued on the belt (1) in a way that lets it be removed later.
  • Will-be-printed material inputs to the machine from the inlet of the will-be-printed material to the machine (2) is glued on the belt (1) by the cylinder to glue the will-be-printed material (6) in a way that lets it be removed later.
  • the aim here is to avoid involuntary movements of will-be-printed material during printing. While the will-be-printed material glued onto the belt (3) moves along together with the belt with a fixed speed, printing is performed by spraying paint material from the inkjet printheads (7) and/or the multi-canal inkjet printheads (8) placed inside the inkjet printhead groups which are lined up along the width of the machine in a way to leave no printing gap and will be steady throughout the time of printing (9) in a way that will form the desired pattern.
  • Printing-completed material glued onto the belt (4) is lefts the machine being removed from the belt (1) in the direction of outlet of printing-completed material from the machine (5).
  • Controlled rotation movement is transferred to belt (1), by cylinders carrying and moving the belt (10), redactor driving the cylinder (11) and belt moving motor (12).
  • After printing the belt (1) is washed with the belt washing system (13), and dried with the belt drying system (14).
  • Continuous inkjet digital printing machines are produced as complying to the single pass printing method.
  • single pass system printing is performed by spraying the paint materials, which forms the pattern with different colors, from the inkjet printheads (7) and/or the multi-canal inkjet printheads (8) to the will-be-printed material only once.
  • the will-be-printed material moves continuously, there is no room to repeat spraying the identical color paint material to a point more than once.
  • speed of printing is reduced, and more paint material is sprayed to each point.
  • multi-pass printing is performed by scanning the medium multiple times.
  • the machine needs to be equipped with more than one inkjet printhead groups which are lined up along the width of the machine in a way to leave no printing gap and will be steady throughout the time of printing (9), each have the identical color printing materials.
  • the multi-canal inkjet printheads (8) with identical color paint materials.
  • the identical color paint materials should be available on the printing machine in consecutive or within equal distances along the direction from inlet of the will-be-printed material to the machine (2) to outlet of printing-completed material from the machine (5).
  • These paint materials are transferred to the multi-canal inkjet printheads (8) inside the one inkjet printhead groups which are lined up along the width of the machine in a way to leave no printing gap and will be steady throughout the time of printing (9), and are injected here.
