Definitions

  • the invention relates to a method and a device for carrying out a method for producing an at least two-color color transfer print by coating a transfer sheet with the individual color images of the individual image colors, or for producing an at least two-colored one Screen-printed image coated with a printing sheet with color individual images to be applied one after the other, one color individual image from the corresponding color negative or color positive for each color by applying a water-soluble sensitized photo layer to a support surface, Imaging of the color negative or color positive associated with the color used, with appropriate exposure of the sensitized photo layer in an exposure device by means of UV radiation and removal of the unexposed photo layer from all areas not cured by exposure, is produced.
  • a transfer sheet with one of the colors of the image to be produced, the individual color images of the individual color separations in the successively applied color layers from the corresponding color negative or color positive by exposure of a water-soluble, sensitized photo layer applied in each case to the color layer he follows.
  • the photo layer is hardened over the surface of the object to be imaged and covers the underlying color layer as a protective film from the outside.
  • the photo layer in the area surrounding the image to be produced is not hardened and can be removed with water. The removal of the unprotected over liquid paint by means of a solvent 'means then takes place at these sites. If it is a multi-colored motif, several color single images must be applied repeatedly on the transparent transfer sheet.
  • an adhesive is applied to the back of the transfer sheet and thus to the back of the image to be transferred.
  • the adhesive decreases in the regions not covered by the image of the transfer sheet loading large one, so that the outer surface is no residue of the adhesive there on 'more.
  • a particular disadvantage of this known method for producing a single-color or multi-color color transfer print is that the individual operations shown must be repeated for each additional color of the image.
  • the process is very lengthy, with large amounts of paint applied and finally having to be removed with chemical solvents.
  • the one coated with a new color layer and photo layer Transfer sheet is to be introduced with the mounting sheet carrying the color negatives into a flat imagesetter, with alignment marks usually being aligned there using register marks and the color negatives of the mounting sheet associated with the color last used being assigned.
  • the transfer sheet and the aligned mounting sheet are to be attached with stickers.
  • only inaccurate printing and inadequate preparation of the pressure are possible in a lengthy process.
  • known screen printing methods the generation of a multicolored screen printing image also encounters difficulties. It is not possible to produce a multi-color print with a single printing screen through the printing frame clamped in the printing press.
  • a method according to the main claim is provided to achieve this object.
  • the color negatives or color positives mounted on the mounting sheet are advantageously imaged simultaneously with exposure of the photo layer of a screen printing frame, so that the printing forms of the individual color images on the outside of the printing screen can be developed in a single process step. It is possible to use certain surface sections of the screen printing frame when using one on a carrier film capillary film as a photo layer from this, this open area of the printing screen is covered by adhesive tapes and the like.
  • the printout of the individual color separations of the image is considerably shortened in that the printing or transfer sheet no longer has to be coated with a photo layer and one color over the entire printing field, but the screen printing frame now to be used serves as a support for the photo layer and thereby Generation of the "positive color single images or printing forms opened in the screen printing area, only a color coating with several colors one behind the other in exact fit above the multicolored image to be generated by the opening of the positive printing forms" must take place.
  • An exposure on the photo film of the stencil sheet is carried out for all existing color negative or color-posi- tive simultaneously, side by side not cured first by these figures by the UV radiation color frames' are generated, the environment on the other hand by the UV- Radiation exposed and in this respect. is hardened. It is thus possible to wash the uncured photo layer of the individual images by means of water in the conventional method, so that positive open printing forms of the individual color images are created in the screen printing area, these being shown next to one another on the printing screen in an elongated section are.
  • This method advantageously uses a screen-printed flat frame, the frame profile height of which is less than 10 mm.

  • the color negatives or color positives can be imaged on the photo layer of the screen printing flat frame, which is also fixed on the fitting bar in a precisely defined position, so that later on the printing table via the predetermined printing field of the printing sheet, the adjacent printing forms of the individual color images opened in the screen printing area can be brought into exact fit using the registration system using the image to be printed.

  • the fitting strips are preferably not slidably mounted, at least in the printing table, but fixedly attached, so that the accuracy of the pressure is not jeopardized. If a good is to be printed, which stretches in the material during printing, this lower fitting bar, on the other hand, is mounted for readjustment.
  • Screen printing flat frame with the illustrated passport system is suitable in particular also for printing circuit boards for electrical circuits, the advantages presented darge the printing process, in particular desse 'n accuracy, are also given.
  • several photo layers can be applied one above the other on the screen printing surface, so that a plastic impression can be made.
  • This cleaning process is particularly environmentally friendly since only small amounts of solvent are necessary for cleaning. In this respect, there are also low costs for the use and storage of the screen printing flat frame.

Abstract

Dans un procédé pour produire une impression par transfert chromatique ou une image sérigraphique polychrome, les négatifs des couleurs correspondant aux images individuelles des couleurs (séparations des couleurs) du motif de l'image multicolore sont reproduits côte à côte et développés à titre de formes adjacentes (17, 18, 19, 20) sur un seul châssis sérigraphique (26). Un système de repérage commun constitué de listels de repérage (20) et de trous de registre filetés dans la feuille de mise en page, dans la copie de support servant à l'agencement des négatifs des couleurs sur cette dernière, et dans le châssis sérigraphique (26), permet une mise en page reproductible, extrêmement simple et en registre, des négatifs des couleurs sur le châssis sérigraphique (26). Il en résulte un photogramme spatialement défini des différents négatifs des couleurs à travers la feuille de mise en page transparente sur la couche photographique (29) de la trame (28). Grâce au guidage et au déplacement latéral par palier ou à la rotation du châssis sérigraphique (26), il est possible de placer ce dernier sur le marbre (16) sur un second listel de repérage (10) de ce dernier au moyen du trou de registre (37), de sorte que les différentes formes ouvertes (17, 18, 19, 20) peuvent être amenées en registre sur les images individuelles des couleurs qui sont superposées, aux fins de leur impression, sur la surface d'impression.
