  • Patent number: 6300040
    Abstract: The effects of interfacial transition between organic and inorganic layers of a lithographic printing member are ameliorated by incorporating an inorganic component within the matrix of the organic layer. In a first aspect, a lithographic printing plate having adjacent organic and inorganic layers is fabricated by depositing a curable polymer, softening the polymer, and integrating an inorganic material therewith. The polymer is then cured to immobilize the integrated deposition material, and the desired inorganic layer is applied over the deposited inorganic material (and any exposed portions of the polymer). In a second aspect, a graded structure is built up on a substrate in successive deposition steps. Both polymer precursors and an inorganic filler material are deposited in stages, with each stage containing a desired ratio of polymer to filler.

  • Patent number: 4767694
    Abstract: The invention relates to a method of preparing a varnish blanket. Instead of a proof being used for pre-location of required varnish-free zones on a blanket for blanked-out in-line varnishing in rotary presses, the zones required not to be varnished are transferred by means of a reference copy, and after physico-chemical pretreatment adapted to the surface properties of the blanket, to a blanket stuck to a support plate. In addition to polyvinyl alcohol copying layers or coatings sensitized by bichromate, wipe-on copying layers sensitized by diazo salts are suitable, a positive or negative original being copied by direct contact in known manner onto a blanket thus pretreated. The zones required not to be varnished can therefore be preformed by cutting out the top layer of the blanket.

  • Patent number: 4258125
    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 thermoplastic plate, for example one of polypropylene or nylon, fabricated so it has an open-cell structure, has a radiation transparent cover sheet applied to one face thereof. The cover sheet has an energy absorbing coating (e.g. of carbon and nitrocellulose) in intimate contact with the plate. A modulated laser beam is then transmitted through said cover sheet to selectively transfer some of the energy absorbing material to the plate according to the configuration required to define the areas of relief desired in the plate. The cover sheet is then removed except for the portion of the energy absorbing coating transferred to the plate. The plate is heated (either before or after the foregoing steps) to a temperature just below the temperature at which the thermoplastic radically changes viscosity. The entire surface of the plate is then exposed to infra-red rays.
