Abstract:
A compact print making device by which a desired imprint figure can be made easily in a short time. This print making device employs a resin seal face member, a part of which receives light having a wavelength within a predetermined range and thus is put into a state different from the state of the remaining part thereof and is adapted to have an uneven face formed by being acted upon by a predetermined fluid. The resin seal face member and an original picture representing an imprint figure are arranged with the original picture just in back of the resin seal face member. Imprint figure information representing the imprint figure shown in the original picture is taken in by an information reading mechanism. A negative film making unit is driven according to the imprint figure information so as to produce a negative film. Then, the produced negative film is carried to an irradiating position. Subsequently, a light irradiating unit irradiates the resin seal face member with light through the negative film. Thereby, the state of the area, which corresponds to the imprint figure, of the resin seal face member or the remaining part thereof is changed. Finally, an uneven face serving as a seal is formed by applying a developing fluid to this resin seal face member.
Abstract:
A method and apparatus for preparing a printing plate without the need for a photomask formed from a sheet of photographic film bearing the positive or negative of the image to be printed. According to the invention, an ink jet print head deposits ink onto a light-sensitive emulsion in a pattern which corresponds to either the positive or negative of the image to be printed. The printed pattern provides a photomask for subsequent exposure of the emulsion.
Abstract:
1. A method for making patterns in organic polymer films comprising the following steps:(a) applying to a substrate an unpatterned photosensitive first layer comprising (a1) an organic polymeric binder, (a2) an ethylenically unsaturated monomer and (a3) a photoinitiating system;(b) applying to the photosensitive first layer a second patterning layer comprising (b1) radiation-opaque material which prevents the transmission of actinic radiation and (b2) a diffusing agent which is capable of changing the dispersibility of the photosensitive material in a predetermined eluant;(c) exposing the first photosensitive layer to actinic radiation to effect photohardening of the photosensitive first layer in those areas not covered by the second patterning layer;(d) effecting patterned diffusion of the diffusing agent into the underlying first photosensitive layer; and(e) removing the areas of the first photosensitive layer which are dispersible in the predetermined eluant, by washing them with the eluant; wherein step (c) is carried out before, after or simultaneously with step (d).
Abstract:
A method for preparing a lithographic printing plate and a light-sensitive material for a lithographic printing plate are disclosed. The method comprises providing a light-sensitive material comprising an electroconductive support having a hydrophilic surface. Provided on the surface is a light-sensitive layer which contains an electroconductive agent as well as a photoconductive insulating layer. The material is imagewise exposed and then electrophotographically processed to form an electrostatic latent image on the photoconductive insulating layer. The exposed material is developed with developer particles which are opaque to the light which the light-sensitive layer is sensitive. The light-sensitive layer of the developed material is exposed through the image. The exposed or unexposed areas of the light-sensitive layer are then removed together with the photoconductive insulating layer. The lithographic printing plate produced has excellent resolving power and does not cause printing stains.
Abstract:
The disclosed light-sensitive recording material is composed of an electrically conductive support, suitable for the production of printing forms or printed circuits, an a photoconductive layer system containing a photoconductor, a binder, a sensitizing dye and conventional additives. The photoconductive system comprises (A) a single photoconductive layer, or multiple layers, applied to the support and (B) a light-sensitive covering layer which contains at least one photochemically reactive compound. The use of the recording material in a process for the production of printing forms and printed circuits is also disclosed.

Abstract:
An imprint method includes supplying a first photocurable resist to a first region of an object; irradiating the first resist with first light; forming a second resist over the object; bringing a template into contact with the second resist; and irradiating at least the second resist with second light through the template while the template is in contact with the second resist.
Abstract:
A method of forming a metallic pattern on a substrate is provided. The method includes applying onto a metallic surface, a chemically surface-activating solution having an activating agent that chemically activates the metallic surface; non-impact printing an etch-resist ink on the activated surface to produce an etch resist mask according to a predetermined pattern, wherein at least one ink component within the etch-resist ink undergoes a chemical reaction with the activated metallic surface to immobilize droplets of the etch-resist ink when hitting the activated surface; performing an etching process to remove unmasked metallic portions that are not covered with the etch resist mask; and removing the etch-resist mask.
