Definitions

  • the invention relates to a device for applying and introducing dyes or a decoration made of dyes onto or into a plastic substrate with a heatable plate on which the substrate and an ink carrier are placed.
  • a method for applying dyes to plastic is known from US Pat. No. 2,721,821.
  • a colored decor is printed on a polyethylene substrate, heating to 120 to 185 ° C.
  • the heating takes place with infrared radiation, which is radiated through the substrate onto the ink carrier, i.e. the ink carrier is heated on its side facing the substrate by means of IR radiation.
  • the ink carrier is formed on its surface, which is not covered by dyes, in a reflective manner for the IR radiation, so that this radiation is absorbed only where paint is applied.
  • GB-A 1 107 401 describes a process for colored printing on plastics, in which the plastic is heated in a heated glycerol bath at 175 to 180 °. The surface of the plastic is gelled.
  • EP 0 098 506 A2 discloses a method and a device for generating permanent images on substrates, in which a support with dye is arranged between the substrate and a heated matrix, which has raised sections, the shape of which corresponds to the image to be transmitted . After the transfer of the dyes to the substrate has taken place by means of this heated matrix, the substrate is heated so that the dye diffuses from an ink into the substrate.
  • DE 24 38 723 A1 describes a method for the dry transfer of organic compounds to webs, in which transfer temperatures between 100 and 200 ° C are provided.
  • GB 2 127 747 A1 describes a transfer printing process in which the transfer printing partners are positioned by means of electrostatic charging.
  • an ink carrier also called auxiliary carrier
  • the ink carrier can in particular consist of paper. Printing takes place, for example, by means of offset or rotary printing processes. The print images are transferred by sublimation from the ink carrier to the textile to be colored (so-called transfer printing).
  • the printing inks mentioned are produced from sublimable disperse dyes using binders and oxidation additives.
  • the printed ink carriers also called transfer papers
  • the printed ink carriers are placed with the color printed side on the textile side to be printed and heated by means of a printing plate heated to 170 to 220 ° C (using the cycle method) or by means of a rotating cylinder (using the continuous process).
  • a printing plate heated to 170 to 220 ° C using the cycle method
  • a rotating cylinder using the continuous process.
  • a known method of the type described (EP-A 0 014 615), which is primarily intended for decorating eyeglass frames, is carried out in such a way that an eyeglass frame with its surface to be decorated is placed on a base with each working cycle is arranged within a vacuum chamber and is movable up and down by means of a piston-cylinder unit.
  • the vacuum chamber has a side opening for inserting the eyeglass frame, which can be closed with a door.
  • the vacuum chamber On its upper side, the vacuum chamber has a horizontal, stationary frame which delimits a slot with a frame which is also arranged above it and is horizontal but can be moved up and down.
  • a carrier film is inserted through the slot, which is rolled off a reel and is provided on the underside with the decor that is to be applied to the spectacle frame.
  • the decor has, for example, been applied to the carrier film as a multicolor print or as a decal and consists of colors which can be sublimed at a temperature below the destruction temperature of the carrier film.
  • the upper frame is lowered so that it clamps the carrier film between itself and the lower frame and the vacuum chamber is thereby sealed and can be evacuated.
  • the carrier film is over heats the upper frame arranged to the sublimation temperature of the decor and then moves the eyeglass frame upwards by means of its base which can be raised and lowered within the vacuum chamber and on which it has been placed, and pressed against the carrier film.
  • the vacuum causes the carrier film to nestle tightly against the surfaces to be decorated on the front and in lateral areas of the spectacle frame. This state is maintained for a period of time sufficient for the colors forming the decor to transition away from the carrier film into the structure of the material of the spectacle frame.
  • the vacuum is then released, the spectacle frame is lowered and thereby separated from the carrier film and finally removed from the vacuum chamber.
  • the carrier film is greatly stretched in individual areas so that it nestles sufficiently against the spectacle frame. It is inevitable that the decor will be distorted in the particularly stretched areas of the carrier film.
  • the distortions can be compensated to a certain extent by applying an appropriately corrected decor to the carrier film from the outset.
  • distortions in objects such as spectacle frames, whose surfaces to be decorated are relatively narrow are hardly noticeable. It is different with objects that are to be decorated over a large area. With such objects, disturbing distortions of the decor cannot always be avoided if the decor has been applied by the known method.
  • the size of the surface to be decorated increases, the risk that the decor will be affected by air pockets.
  • the objects for example tin cans
  • a coating system led which applies a layer of dye-affine, migration-preventing plastic on the outside of the objects.
  • the coated objects are fed to a labeling machine, in which decor carriers in the form of printed banderoles are removed from a stack or endless strips, placed around each object and fixed with an adhesive strip, glue line, electrostatic field or the like will.
  • the objects are then heated, for example by means of hot air, to a temperature of 200 ° to 350 ° C., preferably 250 ° to 300 ° C.
  • a device for printing a textile web with sublimable dye is known, which is fed on a carrier film.
  • the device has a drivable drum that can be heated from the inside, around the bottom of the carrier film with the dye layer turned radially outwards, and above it the textile web to be printed, and above this an endless pressure belt made of metal mesh guided over rollers to run.
  • the region of the drum that is wrapped in this way can be covered by a hood, within which a negative pressure is maintained. In this way, when the ink is sublimed, gas released is sucked through the textile web to be printed and the pressure belt made of metal mesh lying thereon.
  • the pressing forces exerted by the pressure belt on the textile web are generated exclusively by the mechanical tension of the pressure belt and somewhat reduced by the negative pressure inside the hood.
  • thermoplastic films melt or they become so soft that the color substrates (paper etc.) used in transfer printing stick or damage the surfaces of the films so that the product did not meet the aesthetic requirements.
  • the migration resistance of the dyes required for good image reproduction was also not achieved.
  • thermoplastic films and sheets which are thermoformed into three-dimensional bodies, e.g. Components for interior fittings, furniture parts (especially fronts), household appliances, office machines, light bodies, car molded parts, etc., can be molded, there has long been a need for a way to provide good quality thermoplastic substrates with colored decorations.
  • EP 0 014 901 describes an attempt to achieve constant, traceable and stable transfer printing results in that the molecular weights of the sublimable disperse dyes, the temperatures used and the composition and nature of the plastic substrates are specified in more detail. It has come to the conclusion that heating to temperatures of 220 ° C. and more is necessary for the application of the transfer printing process to plastics. This excludes a large number of thermoplastic materials. The process remained limited to certain thermosetting plastic coatings and certain substrates made of inorganic materials.
  • the prior art also teaches as a prejudice that the molecular weight of the dyes used is important in sublimation printing.
  • the aforementioned EP 0 014 901 teaches the use of high molecular weight disperse dyes with molecular weights between 300 and 1,000, in particular with a view to the required resistance to migration.
  • German patents 37 08 855 and 39 04 424 already mentioned at the outset bring progress in that they sublimation printing are based on the use of heated printing plates or heated cylinders and instead suggest heating with thermal radiation (infrared radiation). This prior art does not give details of the materials used or of the sublimation temperatures.

  • the first and second channels preferably extend parallel to one another, specifically in a plane that is parallel to the surface of the plate of the device.
  • first and second channels are preferably arranged alternately offset from one another, but a first channel does not necessarily follow a second channel, but can be arranged between one type of channels of several channels of the other type.
