摘要:
A method for multicolor printing of stock in web or plate form and having a smooth, nonabsorbent surface, includes printing on the stock by the indirect flexographic printing process; assigning each color to be printed to a respective printing unit which includes an inking unit, a cylinder for a flexographic printing form, a transfer cylinder and a counterpressure cylinder; always drying the ink on the stock before passing the stock to the next printing unit; and removing ink located in indentations and on sides, respectively, of the printing surfaces of the flexographic printing form; and a printing press for printing in accordance with the method.

Provided is an optical recording medium comprising at least a recording layer, a metal reflective layer, a protective layer and a printing layer laminated on a transparent substrate, wherein the printing layer is obtained by curing a UV-curing ink composition and said ink composition contains a compound which has a solubility parameter falling in the range of 7 to 10 and which takes no part in UV curing and does not react with other components contained therein.
摘要:
A method for surface coloring plastic objects after manufacture. The method consists of a first step for impregnating a printed paper substrate, whereon pigments of the family known as disperse inks and/or sublimatic inks are deposited within the printing inks, with an aqueous solution of a solvent which activates the print and is capable of activating the surface of the plastic to be treated. Another step consists in covering the parts of the object to be treated with the paper substrate and in then removing the substrate and drying the parts. The final step consists of introduction into an atmosphere of vapors of a product which is a solvent for the pigments, for a time sufficient to fix the pigments to the surface.
摘要:
Electron beam radiation curing of inks on game balls, golf balls and the like is disclosed. Production inks, logo inks and methods for forming production prints and logos on golf balls, game balls and the like are disclosed. To form an electron beam radiation curable water-insoluble production ink, at least an adhesion promoting component is added to an ink base. The adhesion promoting component is selected from the group consisting of a carboxylic acid functional monomer, a carboxylic acid functional oligomer, an ester functional monomer, an ester functional oligomer and mixtures thereof, the adhesion promoting component having at least one adhesion promoting functional moiety comprising at least about 2 moles of a carbonyl functionality per mole of the adhesion promoting component and being sufficient to maintain adhesion of the production ink of at least about 75% of the inked surface to the topcoat and to the surface of the game ball or the golf ball after electron beam radiation curing and after coating the production ink with the topcoat. To form an electron beam radiation curable water-insoluble logo ink, at least a toughening agent is added to an ink base. The toughening agent is sufficient to maintain adhesion of the logo ink to the topcoat of at least about 75% of the inked surface after electron beam radiation curing.
摘要:
A method and related compositions for preparing a substrate for printing are described. The invention comprises coating a non-paper substrate with an adherent base coat and a hydrophilic top coat. The base coat adheres to the substrate and the top coat, which is applied to the base coat and adheres to it, provides an ink receptive surface on which ink pigment can be deposited. A base coating composition comprises a type-A gelatin and an acrylic polymer. A top coating composition comprises a type-A or type-B gelatin and a hydrophilic organic polymer. A base- and top-coated substrate of the invention is particularly suited for use with ink-jet printers that employ aqueous-based inks. Printing substrates include such materials as canvas, leather, polymeric films and sheets, and the like.
摘要:
A method and an apparatus for processing an image transparency entails the application of an intermediate transfer surface of a layer of sacrificial liquid to a supporting surface and the deposition of a phase change ink onto the liquid layer. The inked image is then contact transferred to an optically transmissive final receiving substrate, such as a plastic transparency.
摘要:
A label stock structure comprising a liquid toner printable thermoplastic film is provided. The film is coated with an ethylene-acrylic acid copolymer based coating capable of electrostatic imaging with liquid toner. Optionally, the coating contains acrylic polymer. In a specific embodiment, the coating includes a major proportion of ethylene-acrylic acid and minor amounts of filler such as talc and silica. The coating can also include wax and/or pigment such as titanium dioxide. In a further embodiment, the carboxylate groups of the copolymer are neutralized with metal ions from Group Ia, IIa or IIb of the Period Table of the Elements, specifically, sodium.
摘要:
A printing process includes printing a liquid ink onto a substrate surface. The ink includes a vehicle and a colorant dissolved in the ink. When the ink solidifies on the substrate the colorant, which is substantially insoluble in the solidified ink, migrates and locks to the surface to provide a substantially permanent readable color to the surface.
摘要:
A pigmented ink composition comprising a radiation curable component and a pyrrolopyrrol or isoindolinone pigment; a method for decorating a substrate with the pigmented ink compositions; and a method for decorating a substrate with hot stamping foil and the pigmented ink compositions.
摘要:
A transparent recording sheet coated with a transparent water-based image-receptive coating composition of (1) from about 5 parts by weight to about 95 parts by weight of an oligomer incorporating at least one addition product having at least two reactants wherein one reactant is 3-glycidoxypropylalkoxysilane and the second reactant is at least one secondary amine; (2) from about 5 parts by weight to 95 parts by weight of a colloidal dispersion; (3) optionally, one or more anti-blocking agents; and (4) optionally, one or more surfactants.
