摘要:
A printing unit of a rotary printing press utilizes a "waterless" planographic printing plate which is fastened on a printing cylinder. This "waterless" planographic printing plate receives ink from a short inking unit and directly prints a material to be printed. An additional printing cylinder, that is also equipped with a "waterless" planographic printing plate, acts as the counterpressure cylinder.

A method and apparatus for inking a "waterless" planographic printing plate utilizes an ink application unit and a separating agent application unit. These two units supply conventional ink and a separating agent either directly or indirectly to the planographic printing plate.

Printed products obtained by the planographic printing process whereby printing inks are transferrred by means of a lithographic printing plate to a printing stock, and a corresponding planographic printing process for forming the products. Printing inks which predominantly contain water as a solvent and/or dispersing agent and having a dynamic viscosity of 10 to 250 Pa.s, and printing plates whose information-bearing, i.e., printing, areas are hydrophilic and whose non-printing areas are hydrophobic, are used.

The present invention provides a spark-recording type printing method and a spark-recording material for use in the method, which printing method comprises the processes of: forming an image on a spark-recording material by the spark-recording method, said spark-recording material comprising a support and a layer of metal deposited thereon by vacuum evaporation, and, if necessary, being provided with a colored layer interposed between said support and metal layer, and if further necessary, being provided with a protective layer which is easy to desensitize and/or a desensitized layer which requires no desensitization treatment as formed on said metal layer; and conducting offset printing by employing said spark-recording material having an image formed thereon as a master either after subjecting it to desensitization treatment when it is not provided with said desensitized layer or directly when it is provided with said desensitized layer.

The present invention is a driograhic imaging method which employs an ink comprised of an organic material which is convertible from a state of high viscosity to a state of low viscosity by exposure to high energy radiation. The ink is applied to an inking roller in its initial state of high viscosity and exposed to activating radiation in an imagewise manner to convert the material to a state of low viscosity and thereby reduce the viscosity of the ink in a configuration corresponding to the pattern of radiation. Contacting the irradiated inking roller with a receiving member results in transfer of the ink in imagewise configuration from the inking roller to the receiving member.

A simple machine for making multiple printed copies from a zinc oxide preliminary copy, including a glass cylinder and a transport drum which presses against the cylinder. The machine has a stack holder which is initially filled with a stack of paper sheets and a zinc oxide preliminary copy on top of the paper sheets. Sheet feeding apparatus first moves the preliminary copy onto the transport drum so it moves between the drum and glass cylinder to heat the dark areas on the preliminary copy which represent the image, so that these image regions are transferred to the glass cylinder. Inking rollers then apply ink to the image areas on the cylinder while successive sheets of paper to be printed upon are fed between the roller and glass cylinder.

Functionality is disclosed herein for producing articles with multiple color inks. A method of decorating, printing, or otherwise producing articles with multiple color inks includes continuously refilling an ink reservoir with multiple color inks in a sequential manner, and continuously applying the multiple color inks from the ink reservoir onto articles of manufacture to create decorated articles of manufacture.

A variable lithographic cleaning apparatus, system and method works on the principle that dust and ink residue may be transferred from a lower surface energy reimageable conformable blanket surface to a higher surface energy surface low durometer cleaning member, such as the tacky roller, and then to an even higher surface energy cleaning member, such as the hard roller, which is hard and robust to scratching. The hard roller can then been scrubbed clean by an ink flushing device having a third cleaning member, such as a melamine sponge, wetted with a cleaning solution with the hard roller dried upon each rotation.

The present invention provides a silicone composition for use in a printing plate, the composition including at least: a SiH group-containing compound; a compound represented by the following general formula (I); a compound represented by the following general formula (II); and/or a compound represented by the following general formula (III); wherein Ds in the compound represented by the general formula (I), Gs in the compound represented by the general formula (II) and Js in the compound represented by the general formula (III) each represents an acetoxy group or a dialkyloximino group: A-Si-(D)3 (I) (wherein in the general formula (I), A represents a non-hydrolyzable functional group capable of undergoing a hydrosilylation reaction with a SiH group); E-Si-(G)3 (II) (wherein in the general formula (II), E represents a non-hydrolyzable functional group incapable of undergoing a hydrosilylation reaction with a SiH group); and Si-(J)4 (III). An object of the present invention is to provide a silicone composition for use in a printing plate, for obtaining a planographic printing plate precursor or a planographic printing plate which includes a silicone rubber layer having an excellent adhesion to an underlying layer despite being a fast-curing silicone rubber layer, and which has an excellent ink repellency and scratch resistance.
