Abstract: A printing plate is prepared by the method comprising: (a) providing a substrate; and (b) applying by ink jetting to the substrate a fluid composition comprising an acidic polymeric compound, in which the acid groups of the acidic polymeric compound are at least partially neutralized with base, providing a printing plate that is ready-to-use on a press without having to develop it. The printing plate of this invention is capable of extended press run length and advantageously avoids the need of chemical development.

Abstract: A printing plate with a mesh material, a removable substrate, a substrate, and a paper backing on said substrate. The mesh material has interstices and has first and second surfaces. The substrate is adhered to one of the first and second surfaces of the mesh material and forms a well defined at its bottom by the substrate and at its sides by the interstices of the mesh material, wherein the well receives and stores pigment for printing. Multiple colors of pigment may be stored simultaneously within the wells of the printing plate, thereby enabling those multiple colors to be printed concurrently in a single printing pass operation.

Abstract: Cushions are produced from padding of polyurethane foam cast in situ in a textile covering. There are disposed successively in a mold (1) a textile (2) overlaid by a foam sheet (3) with cells that are open and communicating, and then a fluid-tight film (4), e.g. of glue. The composite (5) thus obtained, adapted to constitute the covering of the cushion, is held against the internal wall (6) of the mold (1) by suction, and then there is cast in the mold (1) a foaming mixture of polyurethane (7) which expands and hardens after closing of the mold (1). Finally, a microperforation of the fluid-tight film (4) is effected, thereby to confer on it good permeability to water vapor and permitting also to generate, by the effect of suction, an underpressure in the foam (8) in the course of hardening, such that the resulting padding of foam (8) will have, after polymerization and demolding, constituent cells (11) that are open and communicating.

Abstract: There is provided a process for preparing a film positive sheet for a forging-by-copying-proof print in which a first background image sheet is placed on a first latent image sheet, an unexposed film having a photosensitive membrane on the undersurface is placed on the background sheet to provide a primary three-layer film structure, the three-layer film structure is illuminated to partially expose the film, the first latent image and background sheets are replaced by second latent image and second background sheets, respectively, to provide a secondary three-layer film structure, the secondary three-layer film structure is illuminated to completely expose the partially exposed film and the second latent image and background sheets are removed from the secondary three-layer structure to thereby provide a film positive sheet for a forging-by-copying-proof print. Then, a forging-by-copying-proof print is prepared from the film positive sheet by a printing method such as offset or relief printing.

Abstract: Disclosed are a light sensitive material and a lithographic printing plate made therefrom by silver complex diffusion transfer process ree from peeling of layer during printing which comprises a polyester film support made hydrophilic by coating with an organic copolymer as a support and at least one undercoat layer, a silver halide emulsion layer and an image receiving layer containing physical development nuclei layer provided on said support in succession, said undercoat layer contiguous to the support containing a polyfunctional epoxy compound having at least three epoxy groups in molecule.

Abstract: A photoelectric transducer receives the light reflected from an original, and outputs color signals representing cyan, green, and yellow. These colors signals are processed by a signal-splitting circuit and a signal-converting circuit, and are thereby converted to image-forming signals representing yellow, magenta, cyan, and black. When a print key of a control panel is depressed, a main control section instructs the signal-converting circuit to continuously output the image-forming signals. In accordance with the output image-forming signals, images are continuously formed on a plastic film, by using an ink ribbon. Hence, a yellow image, a magenta image, a cyan image and a black image can be formed on four plastic films, respectively. These plastic films can be used in making plates to print a multicolor image.

Abstract: Pressure-sensitive master sheets are produced by printing ink-releasing images onto a master sheet by silk screen techniques using a semi-solid printable ink composition comprising a wax and/or resin binder material, an incompatible oleaginous material, colorant and a volatile vehicle. The solidified printed images comprise a porous, spongy network of the binder material containing within the pores thereof the oleaginous material and colorant as a pressure-exudable ink. The printed master is suitable for the production of several copies in a dry pressure-copying process.

Abstract: A toner image is formed on a photosensitive member by going through an electrophotographic process including charging, an original image exposure, and developing. The toner image on the photosensitive member is then transferred onto an image retention medium. Thus transferred toner image is temporarily fixed to the image retention medium by the application of heat, thereby enabling to make multiple copies by applying ink to the fixed toner image to form an ink image and bringing a copy paper in contact with the image retention medium for receiving the ink image. The toner image fixed to the image retention medium is completely removed after use thereby preparing the image retention medium for the subsequent use.

Abstract: A method of making a lithographic product having the printed characteristics of a lithographic product and having the visual characteristics of a product simulating an oil painting. The process includes the step of printing a pictorial representation onto a linen-type canvas material by means of a lithographic process having the artist sign the pictorial representation by hand, and then applying one or more layers of varnish to the linen-type canvas material having the artist signed pictorial representation printed thereon; and, a lithographic product having the visual characteristics simulating an oil painting which includes a linen-type canvas material with a pictorial representation printed thereon by a lithographic process, and a layer of varnish over the pictorial representation.

Abstract: Solvent hectograph compositions which are resistant to rapid thickening and gelling during storage in the presence of ambient humidity comprising a cellulose ether film-forming binder material, at least one oleaginous material which is substantially incompatible with said binder material and a major amount by weight of particulate spirit-soluble solid hectograph imaging material, the volatile solvent for said binder material being a lower aliphatic ester which is a substantial non-solvent for said imaging material and which has a partial miscibility with water, the process of making such compositions and the process of producing pressure-sensitive transfer elements from said compositions.

Abstract: A device for applying pressure to a pressure sensitive duplicating master and a sheet of copy paper positioned on a hard surface includes two rollers of differing hardness. The rollers are used simultaneously with the harder roller applying substantial duplicating pressure while the softer roller conforms to irregularities in the hard surface and prevents these irregularities from causing voids in the duplicated image.
