Abstract: A method for producing a pressure-sensitive dry transfer sheet. A release coating is applied to a base sheet and a pigmented ink is applied over the release coating. A photoresist is applied over the pigmented ink and selected portions of the photoresist are exposed to light. Portions of the photoresist and the pigmented ink that are not to be part of the transfer image are removed, and a pressure sensitive adhesive coating is applied.

Abstract: A table has a mechanically driven draw bar squeegee mounted thereon to spread ink and other substances in a uniform manner. There is an interchangeable plurality of such squeegees which may be sequentially placed in said table to enable successive layers of different types of materials to be spread, in sequence, over the surface of a paper. This succession of materials includes an isolation layer between successive colors of ink, whereby a mistake on work in progress does not necessarily lead to a final destruction of all previously done work. A feature of the invention is that the pigmented surface of dried ink is not seen through the tint of other material, such as photoresist, for example. Also, a releasable layer may be provided among the successive layers so that a hand proof copy may be transferred, as a decalcomania.

Abstract: A font element for use in a photocomposing machine of the type having a rotatable drum which defines light-transmissive portions and carries hooks and buttons for coupling to the font element. The font element comprises a flexible sheet on which character images are arranged and defines apertures for receiving the hooks and buttons, with reinforcing members secured to the opposite edges of the font element. The reinforcing member secured to the trailing edge of the font element extends alongside the button-receiving apertures. This reinforcing member has an angled portion at one of the apertures with the angled portion being located to engage snugly the button received by the aperture.

Abstract: A piece of film is prepared for photographic exposure with a film font so as to produce a duplicate font. The piece of film is initially cut to a proper size and placed between a first supporting platen and a cover plate which is adapted to fit snugly against the film. Hole punches fixed to the bottom of an overlying second platen are moved down and through the film. The film and the original film font are then impaled on a register pin which holds them rigidly together for photographic exposure.

Abstract: A decalcomania image transfer system comprises a non-stretchable base sheet of linear oriented high-impact styrene, with one or more images of flexible decal lacquer formed thereon. The lacquer is applied through a photo emulsion stencil. Subsequently, a pressure-sensitive adhesive is applied through another photo emulsion stencil and over the lacquer image. A very thin outside film of the adhesive dries and forms a surface oxide film, which precludes a sticky feel, but which will break when burnished, to enable the underlying adhesive to attach the image onto a receiving surface.
