METHOD OF FLEXOGRAPHICALLY PRODUCING A FAUX GALVANIZED METAL FINISH ON A SUBSTRATE
A coiled metal substrate with a faux galvanized surface appearance. The faux galvanized surface of the substrate including a spangle print pattern of polyvinylidene fluoride (PFDV) flexographically applied to the metal substrate. Atop the PFDV print pattern is semi-transparent coating of fluoroethylene vinyl ether (FEVE) flexographically applied atop the spangle print pattern of PFDV.
MICROWAVABLE SOLVENT-BASED PACKAGING INK COMPOSITION
Described herein are printing ink compositions suitable for printing of microwavable flexible packaging. The printed black ink exhibits low microwave energy absorption, thus minimizing the risk of charring, arcing, ignition, distortion or burning during microwave heating processes. Nitrocellulose resin, a solvent, a polyurethane resin, and a carbon black pigment having at least one of an imaginary permittivity of 3, preferably 2, and a surface oxygen content of 1 wt % to 3 wt %, preferably 1.5 wt % to 2.5 wt % are among the components of the printing ink compositions. Also described is packaging suitable for exposure to microwave energy upon which the inks have been printed.

FLEXOGRAPHIC PRINTING DEVICE AND A METHOD OF SIMULTANEOUSLY PRINTING AT LEAST TWO MATERIAL WEBS HAVING DIFFERENT THICKNESSES
A flexographic printing device and a method are provided for simultaneously printing at least two material webs having different thicknesses in the printing device. The flexographic printing device includes a printing unit having a printing roller carrying on a surface thereof an image to be printed, an impression roller, and an anilox roller adapted to feed printing ink from a printing ink chamber onto a printing clich mounted on the printing roller. The printing unit is configured for simultaneously printing the material webs having different thicknesses, by adjusting the radial extension of the surface of the printing roller, impression cylinder and/or anilox roller to be adapted to the respective material web to be printed.

ELECTRON BEAM CURABLE COMPOSITIONS COMPRISING POLYOLS
Electron beam curable compositions comprising polyols, and any blend of ethylenically unsaturated monomers and oligomers. The polyols of the invention are preferably essentially free of any ethylenically unsaturated groups, have greater than one hydroxy group and preferably have boiling points in excess of 170 C.
Method for printing images
A method for creating a greater pattern (12) comprising creating a first repeating line pattern (14a) comprising printing a first line (16a) onto a substrate, the first line having a weight of from about 0.2 point to about 0.6 point, printing a second line (16b) onto the substrate at least about 0.3 point and less than about 0.8 point from the first line (16a), the second line (16b) having a weight of from about 0.2 point to about 0.6 point, and printing a third line (16c) onto the substrate at least about 0.3 point and less than about 0.8 point from the second line (16b), the third line (16c) having a weight of from about 0.2 point to about 0.6 point, wherein the first, second and third lines (16a, 16b, 16c) are all printed at a first angle.
Method and device for producing documents
A method and a device for producing a document and a document produced in a corresponding manner are presented, said document being produced from a paper reel (1), being printed in a continuous rotary method, being divided into partial webs (4.1 to 4.4) and being assembled to form a document which is ready for use and has a plurality of sheets or pages. The thickness of individual pages or sheets of said document can be increased by the fact that a gluing machine (26) is integrated into the production process of said document, the gluing machine gluing individual page sections, individual pages or entire sheets of said document to one another. A second paper reel or second type of paper or second paper quality having a higher paper thickness or paper quality is therefore unnecessary.
METHOD OF IMPROVING ACTINIC CURE OF COATINGS
A method for printing on a substrate comprises two steps. The first step consists essentially of: applying onto a substrate one or more layers of an energy curable ink and applying one or more layers of a water-based coating over the top of the one or more layers of energy curable ink. The second step comprises the steps of, in any order: a) drying the one or more layers of water-based coating, and b) actinically or electron beam curing simultaneously all the energy curable ink layers.
Composite panel with barrier layer and method for manufacturing a letterpress plate
A composite panel for use in the manufacture of a letterpress plate has a carrier layer, with at least one photo layer which can be structured via electromagnetic radiation in a wavelength range. The photo layer is arranged on the carrier layer. The task of proposing a composite panel use in the manufacture of a letterpress plate is achieved by the fact that a barrier layer is provided. The barrier layer is arranged on the side of the photo layer opposite to the carrier layer. The barrier layer is essentially transparent in the wavelength range in which the photo layer can be structured. The present disclosure concerns a process for manufacturing a letterpress plate using at least one composite panel and a process for manufacturing a composite plate in accordance with the invention. The invention concerns the use of a composite material in a composite panel for a letterpress plate.
