Definitions

  • the invention relates to a screen printing method according to the preamble of the main claim.
  • retarders must be used with the known methods for shorter downtimes, which prevent the meshes of the sieve from being added to the stencil of dried paint. In any case, after a certain number of prints, it is necessary to interrupt printing and to completely clean the screen of ink, then to reintroduce ink and to print five waste.
  • the invention has for its object to propose a generic method that works faster and without rejects.
  • the method according to the invention ensures that the printed object does not adhere to the stencil, so that it can be printed more quickly. In addition, the printed object does not kick back, so that fewer rejects occur. Surprisingly, it has been found that even without the use of retarders there is greater sieve stability, i.e. in the case of shorter normal interruptions, no delay must be used. It has also been found that the mesh of the sieve does not clog as quickly due to the measure according to the invention. Thus, the interval between cleaning intervals when using the method according to the invention is greater, the downtimes are shorter, less cleaning material is required, and indeed with less waste.
  • a printing table 5 is provided on which a flat object 6 to be printed, for example a printing material, is placed. Then vacuum is applied to the printing table 5 so that the object adheres firmly to the surface.
  • a flat object 6 to be printed for example a printing material
  • the template 7 has the color on its back 8. This is pressed by means of a squeegee through the mesh of the sieve to the front 10 during its longitudinal movement over the back 8 of the template 7. An ionization electrode 11 extending over the same width is moved parallel to the doctor blade 9 and preferably behind the doctor blade 9.
  • the printing table 5 with the object 6 is moved under the template according to directional arrow 12 (FIG. 2), which is then lowered according to directional arrow 13. Then (not shown), the doctor blade 9 is moved back and forth together with the ionization electrode 11 once, the actual printing process taking place.
  • the front side 14 is held by means of a gripper 15 and the printing table 5 against the direction 12, namely against the direction 16, from the space between the template 7 and the one located below and according to the directional arrow 17.
  • the second direction revolving conveyor belt 18 so that the object 6 can then sink in the direction of arrow 13, namely after loosening the gripper 15 on the conveyor belt.
  • both electrodes Preferably on the lower run 19 of the conveyor belt 18 there is a further ionization electrode 20, which are known per se.
  • both electrodes have alternating individual electrodes perpendicular to the plane of the drawing, which are combined in pairs and of which one group is connected to positive high direct voltage and the other to negative direct voltage and each individual electrode of one group is adjacent to two individual electrodes of the other group.
