Abstract:
The present invention provides a process for preparing a printing plate, comprising the steps of: providing an N-type photoconductor layer having an optical memory property on the surface of a substrate having an electrical conductivity at least in its surface to form an N-type photoconductor substrate; subjecting the N-type photoconductor layer to a desired pattern-wise exposure by batch exposure and/or photo-drawing exposure to render exposed areas electrically conductive; immersing the N-type photoconductor substrate in an electrodeposition bath to electrodeposit an ionic organic polymer contained in the electrodeposition bath to form an electrodeposit layer; and washing and drying the electrodeposited substrate to prepare a printing plate.Further, the present invention provides a process for preparing a printing plate, comprising the steps of: subjecting an N-type photoconductor layer provided on an N-type photoconductor substrate to a desired pattern exposure by batch exposure and/or photo-drawing exposure to render exposed areas electrically conductive; electrodepositing an ink-receptive component on the exposed areas; and transferring the ink-receptive component onto a substrate for a printing plate to prepare a printing plate having an ink-receptive area.Furthermore, the present invention provides a process for preparing a printing plate, comprising the steps of: exposing the whole surface or a necessary region of an N-type photoconductor layer provided on an N-type photoconductor substrate, thereby rendering exposed areas electrically conductive; heating the exposed areas by hot pattern drawing to erase the conductivity of the heated areas; and electrodepositing an electrodeposition material on the remaining conductive areas to form an electrodeposit layer.
Abstract:
Prior to the press-contact between a pattern-transferring flat plate and a transfer-receiving flat plate, at least one of these flat plates is moved to a predetermined position to effect the positioning therebetween, while the positional relation between the pattern-transferring flat plate and the transfer-receiving flat plate is optically observed, and thereafter these flat plates are sequentially press-contacted to each other from an end of the flat plates. Therefore, there is no positional difference between the flat plates which have been correctly positioned, and further the adhesion strength between the transfer pattern and the transfer-receiving flat plate is uniform.
Abstract:
A fine pattern is formed by the following steps. A prescribed mask pattern of an electrically insulative material is formed on an electroconductive surface of a base plate of a printing plate, so that the part, other than the mask pattern, of the printing plate becomes an electroconductive printing pattern part. Then, electrolysis is carried out in an electrolyte containing an electrodeposition substance as an ingredient with the printing plate as one electrode and with an opposing electrode, both immersed in the electrolyte, so that the electrodeposition substance is deposited on the electroconductive printing pattern part of the printing plate. Thereafter, the printing plate is withdrawn out from the electrolyte, washed and dried. Then, the deposited substance is transferred onto the surface of a printing object such as a plate of glass or plastic, for forming a pattern thereon. Thereafter, the surface of the printing object is etched with the electrodeposited substance thus transferred as an erosion resistant material. The transfer of the electrodeposition substance without consistency from the printing plate onto the surface of the printing object, followed by etching of the printing object surface, enables an accurate reproduction of a fine pattern on the printing object.
Abstract:
A new data recording method is provided in which a consumed amount of predetermined value is recorded in a card memory. Two recording areas are provided in a card memory. The first recording area consists of a plurality of record bits (a through j) which are unchangeable when marked. The second recording area consists of a changeable memory (M). Upper digits of the consumed amount are recorded in the first recording area so as to improve the factor of safety and lower digits of the consumed amount are recorded in the second recording area so as to improve the factor of freedom.
Abstract:
For contact-printing an original such as a photographic negative on a light-sensitive material a vacuum printing frame is provided which comprises a first vacuum chamber between a light-transmitting plate and an elastic diaphragm, and a second vacuum chamber opposed to the first vacuum chamber across the diaphragm. The two vacuum chambers are evacuated simultaneously, with the original and sensitive material mounted in superposition in the first vacuum chamber. Upon subsequent introduction of atmospheric pressure into the second vacuum chamber the original and the sensitive material make close, uniform contact with each other, thereby making themselves ready for exposure. Another embodiment employs a third vacuum chamber disposed opposite to the first vacuum chamber across the light-transmitting plate. Evacuated simultaneously with the first and second vacuum chambers, the third vacuum chamber makes possible the use of a thinner light-transmitting plate, which normally is of glass. The invention is also disclosed as adapted for continuous printing operation.
