Abstract:
Provided are an offset printing plate, an offset printing apparatus, and an offset printing method, which are capable of printing a high-definition image by waterless offset printing.The offset printing plate comprises: a cylindrical plate base material; a silicon resin layer formed on the cylindrical plate base material; and a resist pattern part formed on the silicon resin layer, in which the silicon resin layer serves as a non-printing area, and the resist pattern part serves as a printing area. The silicon resin layer is preferably formed on the cylindrical plate base material seamlessly.
Abstract:
A pair of metallic beverage container bodies is sequentially decorated in a direct single file queue by a dry offset rotary metallic beverage container decorator. A container body has a common design element, a first unique design element in a first color, and a second unique design element in a second color on its outer surface. The first unique design element is located within a boundary of the second unique design element. A second container body has the common design element, a third unique design element in the first color, and a fourth unique design element in the second color on the outer surface. The third unique design element is unique relative to the first and second design elements. The third unique design element is located within a boundary of the fourth unique design element.
Abstract:
A dry offset printing process using a printing apparatus including a) at least one inker block, each block inking a relief plate corresponding to one color of the final motif to be reproduced on an object and including an inker and a succession of transfer rollers, and b) a central blanket which can be placed into contact with the object to be decorated. An ink of suitable tackiness is selected, and the temperature of the ink is regulated in the inker to a predetermined temperature between 15.degree. and 30.degree. C.
Abstract:
An improved method of making lithographic reproductions is disclosed. The method involves several improvements over prior processes, including (a) the combination of random plates and a waterless, dry press for halftone, duotone, tritone and four color separation halftone printing, and (b) the use, in duotone, tritone and four color separation halftone printing of random plates exclusively for all the plates involved in the multi-step printing process.
Abstract:
The invention relates to a pressure-sensitive, carbonless copying system and to a process for the production of pressure-sensitive, carbonless copying system wherein a non-aqueous, substantially solvent free printing ink containing micro-capsules which contain dye-precursors, is applied by wet and dry offset and book printing techniques to all or part of at least one surface of a paper substrate; and to printing inks comprising(1) binders, (2) microcapsules containing dye precursors, (3) spacers having a grain size of from 1.5 to 10 times the diameter of the microcapsules, and optionally auxiliaries and additives.
Abstract:
An ink composition for waterless lithography having good printing properties which makes it possible to print from a lithographic printing plate with one fluid without using any kind of water fountain system to mask a non-image area, said ink composition containing high-boiling petroleum solvent mixtures which have a boiling point higher than 200.degree. C. and which contain less than 5% by volume of aromatic components, and in addition to the above containing an aliphatic acid ester, an aliphatic dibasic acid ester and/or a phosphoric acid ester.
Abstract:
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.
Abstract:
A lithographic ink which has a highly sensitive curability for active energy beam simultaneously with a high washability with water, and which also has excellent resistance to surface staining in the printing and high water resistance of the cured film is provided. Also provided are a varnish for such lithographic ink and a method for producing printed material. The lithographic ink comprises (a) a pigment and (b) a resin having an ethylenically unsaturated group and a hydrophilic group, and it has a highly sensitive curability for active energy beam simultaneously with a high washability with water, and also, excellent resistance to surface staining in the printing and high water resistance of the cured film.
Abstract:
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
