  • Background art on how to remove and prevent dirt due to the adhesion of printing ink to the non-image area of the plate or the surface of the cut roller
  • Offset printing is basically printing that makes use of the repulsion of water and oil. Specifically, a printing plate, in which an image portion made of resin is printed on a base made of an etched aluminum plate or the like, is placed on the surface of the plate cylinder opening one-color. Attach, apply water from a water tank to the image portion of the printing plate with a pet roller, while ink image is applied to the image portion of the printing plate. The ink in the image area is transferred to a rubber roller and then transferred to printing paper.
  • the non-image portion of the printing plate is an etching surface as described above, so that water can be diffused to details. Therefore, oily stains such as printing inks are liable to adhere, and it is extremely difficult to peel and remove the once adhered stains from the non-image area. Have difficulty Similarly, water is supplied to the non-image area of the printing plate. ⁇ If oily dirt such as printing ink adheres to the surface of the nip roller, the non-image area will be supplied. Water supply to the city is not smoothly carried out.
  • the etching liquid removes oily dirt such as the printing ink attached to the surface of the non-image area of the printing plate and the roller around the water roller.
  • its components often contain hexavalent chromium, cyanide compounds, etc., and are toxic. There is a problem.
  • draughts and water due to the etching solution accumulate in the water tank, it may adversely affect printing, etc., and furthermore, Such an etching solution also has disadvantages such as being relatively expensive.
  • IPA has the effect of lowering the surface tension of water on the printing plate or ⁇ Ettroller, and has the effect of adding IPA. Diffusion of water on the surface of the print roller is enhanced, and as a result, printing on the print plate or the surface of the jet roller is enhanced. This prevents the adhesion of oily soil such as ink, but this IPA is toxic. In addition, there are problems such as harming the health of workers by sucking this. In addition, IPA has the same disadvantages as the etching solution, which is relatively expensive.
  • the present invention is not to use the etching liquid IPA, or to greatly reduce the amount of the IPA to be used for the offset printing.
  • the supersonic wave is transmitted to the plate roller to which the printing plate can be attached.

  • a supersonic wave is irradiated
  • the printing plate is irradiated with the supersonic wave evenly to the print roller.
  • the ultrasonic vibration causes water to spread to the details of the etching surface of the non-image portion of the printing plate, and thus to the non-image portion of the printing plate.

Abstract

Procédé servant à empêcher qu'une partie ne comportant pas d'image d'une planche d'impression et la surface d'un cylindre humide dans une imprimante offset ne soient salies par une substance huileuse, telle que de l'encre d'impression, par l'application d'ondes ultrasoniques, provenant de générateurs d'ondes ultrasoniques montés sur un cylindre porte-plaque et sur le cylindre humide, sur les surfaces de ces mêmes cylindres en mouvement. Selon ce procédé, on peut prévenir efficacement le dépôt de matériau huileux, tel que de l'encre d'impression, sur une partie ne comportant pas d'image d'une planche d'impression et sur la surface du cylindre humide à l'aide d'un appareil de conception très simple.
