Definitions

  • the invention proposes simply to apply a thin film of elastic or fiexible material, particularly caoutchouc, tothe form, the film being sucked on by means of a'high vacuum and thus so firmly and completely drawn and adapted to the form that the outlines of the carrier of the matter to be printed and all unevenesses of the form distinctly reappear on the surface of the film.
  • the film Owing to the vacuum produced, the film, by exterior atmospheric pressure, is firmly pressed onto the form and the foundation bearing-the latter but not cooperating in printing, so that the film becomes perfectly adapted'to the outlines. In this manner it will be possible to convert even materials which usually cannot be employed for carriers but which are much cheaper than the a usual ones, such as blotting paper, sand paper,
  • the elastic film pressed on by the vacuum is so firmly applied to the foundation and the carriers of the matter to be printed that the-latter are thoroughly pressed on to the foundation and need not be specially fastened thereto by pasting, etc.
  • l is the foundation consisting preferably of a solid piece of metal, though it may comprise also several parts.
  • the foundation i contains one or more longitudinal channels 2 whence outlet conduits' 3 lead to the surface of the foundation.
  • the printing form 4 is placed on the perfectly smooth surface of the foundation i and may consist .of a piece of cardboard or sheet metal treated in intaglio or embossed or cut out according to the matter to be printed, or which may comprise a plurality of parts having the effect of cuts.
  • any other material possessing suflicient strength may be employed'for producing the form, and it is therefore possible to use for instance wires 40. to produce lines in printing.
  • a very thin elastic film 5 is put the edges of which are preferably pasted onto the free surface of the foundation.
  • the surface of the foundation and the film 5 form a closed space whence air is drawn off by the conduits 2 and 3.
  • the drawingoff of the air causes the film 5 tobe so firmly pressed against the foundation and the parts lying thereon by atmospheric pres-- sure that the finest details of the parts as well is rough or fitted with elevations like sand paper.
  • the intermediate layer will also render the suction effect more uniform.
  • the invention is applied to the color sheets produced in the usual manner.
  • the elastic film easily adapts itself also to the unevennesses of the material on which the impression is to be made, so that printing can be done with less color'and without making ready and interleaving may be dispensed with.
  • a printing device comprising a character, a separate flexible sheet, and suction means for releasably and intimately uniting the sheet with the character whereby the contour of the latter is transmitted to the sheet presenting a printing surface.
  • a printing device comprising a character, a separate flexible sheet, and means for releasably and intimately uniting the sheet with the character whereby the contour of the latter is transmitted to the sheet presenting a printing surface.
  • a printing device comprising a base, a character, a separate elastic film, and'means for releasably and intimately uniting the film with the base and character whereby the contour of the character is transmitted to the film presenting a printing surface.
  • a printing device comprising a base, a character, a flexible sheet, and suction means, said means being operable for fixing the character on the base, and for intimately uniting the sheet with the character to present a printing surface substantially having the contour of the character.
  • a printing device comprising a character, a thin flexible sheet presenting a printing surface, and means for releasably impelling the said sheet into intimate contact with said character whereby the contour of the character may be transmitted to said surface.
  • a printing device comprising a base, a character upon a surface of said base, a flexible film over and removable from said character, and means to intimately and removably unite said film to said character, said means including a passageway in said base connecting with its said surface and means to evacuate air through said passageway.
  • a printing device comprising a base. a character associated with said base, a plate intermediate said base and said character, said plate having a roughened surface, a thin flexible sheet over said character and said base and presenting a printing surface, and suction means for releasably holding thebase, plate, character and sheet in respective intimate contact and whereby the contour of the character is transmitted to said surface, said plate facilitating the suction efiect.
  • a printing device comprising a base, a character on said base, a film, and a flexible layer having a predetermined pattern or design disposed between said film and said character, said film intimately covering said character whereby the sheet substantially simulates the contour of the character.
  • a printing device comprising a base, a character on said base, a film, a flexible layer having a predetermined pattern or design disposed between said fllm and said character, and means to releasably secure said film to said layer, said means including a passageway in said base leading to a surface thereof and means to exhaust I substantially simulates the contour of the character.
  • a printing device comprising a base, a character associated with said base, said character being made of fibrous material, a separate thin flexible sheet covering said character, and means to releasably secure said film to said base,
  • said means including a passageway in said base leading to a surface thereof and means to exhaust air throughsaid passageway.
  • the method of producing a device for printing which consists in interposing a character between a flexible film and. a base and exhausting the air from between said film and base whereby the character is forced into relief.
