Abstract:
The present invention relates to water based wax dispersion comprising a hydrocarbon wax and a dialkylether for the coating of paper products, the use thereof, the method of coating paper products therewith and the coated printed paper product.
Abstract:
The disclosure relates to a method and equipment to form a digital print by displacing a panel under a digital drop application head (30') for applying a liquid binder (11) on a surface (2) of the panel, applying colourants (7) on the surface, bonding a part of the colourants to the surface with the liquid binder, removing non-bonded colourants and permanently bond the colourants to the surface by applying heat and pressure.
Abstract:
The wraparound covering for a printing or varnishing plate cylinder for the surface finishing of a printed substrate, has a film of varnish in at least one zone of the surface thereof intended for contact with the substrate

Digital thermographic methods and systems for CMYK plus raised print products, and corresponding thermographic CMYK plus raised print products.
Abstract:
A method for covering a pattern on a surface of a vacuum-molded three-dimensional article comprises the following steps: printing a desired pattern on a plastic film (30) by gravure printing; hot-pressing the printed plastic film (30) with a plastic board or sheet (10) so that the ink layer (20) of pattern is formed between the plastic film (30) and the plastic board or sheet (10); forming the plastic board or sheet with the pattern into a desired three-dimensional shape by a hot-forming process.
Abstract:
The present invention includes compositions and methods for preparing a varnish a modified rosin ester, one or more vegetable oils, one or more hydrogenated middle distillates-alkyd, a microcrystalline wax; and one or more light aliphatic, medium aliphatic and light aromatic napthas; coating a paper product with a composition using printing equipment; and drying the coating.
Abstract:
A packaged food product includes a food product and a package enclosing the food product. The package may be formed from a coated, printed film that includes a substrate film including one or more thermoplastic materials and having an average thickness of less than about 15 mils. An image is printed on the print side of the substrate film. A radiation-cured varnish covers the printed image. The radiation-cured varnish was formed gy coasting the printed image with a radiation-curable varnish that includes one or more polymerizable reactants and optionally one or more photoinitiators. The radiation-curable varnish is subsequently exposed to radiation sufficient to polymerize at least 90 weight % of the polymerizable reactants. When the coated, printed film is tested according to the FDA migration test protocol, no more than 50 parts per billion total of any of the polymerizable reactants and the optional photoinitiators migrate within 10 days at the 40 DEG C from the coated, printed film into a food simulant of 95 weight % ethanol and 5 weight % water enclosed within a test container formed from the coated, printed film so that the food simulant contacts the food side of the substrate film and the ratio of volume of food simulant to surface area of coated, printed film is 10 milliliters per square inch.
Abstract:
A printed antifog packaging film incorporates a cured reactive ink system or a cured reactive varnish system. The reactive ink system includes a radiation-cured ink or a cured thermoset ink. The reactive varnish system includes a radiation-cured varnish or a cured thermoset varnish. The cured reactive ink or varnish reduces the tendency of the antifog film to form a ghost condensate image of the printed image after the film has been unwound from a roll form and subjected to conditions that form moisture condensation on the film.
Abstract:
A method and device for raised letter or graphics printing, by means of a sprayed wet ink deposition on a print substrate. Subsequent dispensed thermographic powder thereon, with adherence of the powder only to the wet ink and heating thereafter, to a fixing temperature of the powder, results in the raised lettering or graphics. A standard portable ink jet printer (20) of the bubble jet type, controlled, with graphics software control, by a personal computer, provides the requisite non-contacting ink deposition. The dispensing cartridge (s) (23) of the ink jet printer is (are) provided with non-contacting-drying ink formulations for the portion of graphics or printing which is to be in raised form. A thermographic powder dispenser (33) and heating member (35) is connected to the output of the ink jet printer (20) for completion of the raised printing process. The device is particularly useful in providing non-impact formed braille lettering.
