摘要： 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.

摘要： The present invention provides a flexographic printing plate in which the dot gain of fine dots in a fade-out part is reduced and printability is improved. A flexographic printing plate obtained from a flexographic printing plate precursor comprising at least a support (A), a photosensitive resin layer (B) and a heat-sensitive mask layer (C) which are laminated in this order, characterized in that, when dots each having a diameter of 16 μm are formed at 175 lpi on the printing plate, the dots do not buckle until a load of 0.2 N is applied thereto. Preferably, when dots each having a diameter of 16 μm are formed at 175 lpi on the printing plate, the shoulder angle of each dot is 105 to 125° and the dot depth is 70 to 85 μm.

摘要： The present invention relates to a printing form for flexographic printing. The printing form contains microcell patterns on its relief printing surface. The presence of these microcell patterns allows for printing with a higher anilox roll volume. Also disclosed are five specific microcell patterns.

摘要： A flexographic printing system prints image patterns including one or more uniform image regions on a substrate. A flexographic printing plate includes a pattern of raised features for transferring ink to the substrate in accordance with the image pattern. An anilox roller having a plurality of anilox cells is configured to transfer ink to the flexographic printing plate. Uniform image regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised feature shapes positioned in a pattern of pseudo-random feature locations. An average spacing between the raised feature shapes in the uniform image regions is less than an anilox cell size such that a plurality of the raised feature shapes receive ink from a single anilox cell of the anilox roller.

摘要： Described herein is a printing ink or coating composition that includes: (a) one or more elastomeric polyurethane resins with amine functionality having a glass transition temperature of about −45° C. to about −70° C.; (b) one or more acrylic resins based on a methacrylate/styrene co-polymer with a glass transition temperature of about 45° C. to about 110° C.; (c) one or more nitrocellulose binders; (d) one or more solvents; and (e) optionally, one or more waxes and/or one or more colorants. The inks and coating compositions are well suited for printing onto shrink sleeve label substrates, such as by flexographic and gravure printing. The inks and coatings provide exceptional printability and resistance to chemicals, to softening, to re-wetting, and to set-off.

摘要： An object of the present invention is to provide a water-developable flexographic printing plate precursor, a flexographic printing plate, and a photosensitive resin composition, which can maintain good water developability and can suppress adhesion and aggregation of dispersion in the developer in a case of repeated use and disposal of the aqueous developer. The water-developable flexographic printing plate precursor of the present invention is a water-developable flexographic printing plate precursor including a photosensitive layer, in which the photosensitive layer contains water-dispersible particles, and the water-dispersible particles have a core containing a polymer and having a glass transition temperature of 0° C. or lower and have a shell containing a polymer and having a glass transition temperature of 10° C. or higher.

摘要： A method for the determination of print parameters of a printing machine, particularly a flexographic printing machine, comprises the following steps: First, a print form (12) is provided and mounted on a print cylinder (14). Then, at least one high-resolution image of the surface of the print form (12) is recorded by means of a 3D camera (18). On the basis of the at least one high-resolution image a height profile of the print form (12) is determined and then a simulated print image is calculated on the basis of the height profile and an initial set of print parameters. Finally, optimized print parameters are determined by checking and/or varying the print parameters of the initial set. For this purpose, a simulated print image is calculated again after the print parameters have been varied.
In addition, a test stand is specified on which such a method can be carried out.-

摘要： Energy curable compositions comprising polyols, and any blend of ethylenically unsaturated monomers and oligomers. The polyols of the invention are essentially free of any ethylenically unsaturated groups. It is preferred that the polyol substances according to the invention have greater than one hydroxy group and preferably have boiling points in excess of 170° C. The compositions of the invention are particularly useful for the printing or coating of food packaging and may be applied via any printing or coating method, although inkjet printing is a preferred method.

摘要： 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.
