A gravure printing system comprising a gravure cylinder having a first plurality of discrete cells disposed upon an outer surface thereof is disclosed. Each cell of said first plurality of discrete cells has a nominal diameter and is capable of receiving a fluid that is a first combination of at least two primary fluids. The fluid is fluidically displaceable through a discrete channel having a single entry point at said first position and a single exit point into a first cell of said first plurality of discrete cells. The outer surface has a metal plating disposed thereon. The metal plating reduces the nominal diameter of each cell of the first plurality of discrete cells.

Provided are a blade device equipped with a blade member which can accurately adjust pressing force due to a blade member, and a printing machine and a coating device equipped with the blade device. A blade device according to the present invention has: a blade member contacting with a plate roll to which coating material is to be applied; an upper holder contacting with the blade member from one surface side of the blade member; a lower holder contacting with the blade member from another surface side of the blade member; a tube contacting with the blade member and configured to expand and contract by pressure of fluid; and a tube positioning part which is provided on the upper holder and positions the tube closer to the roller, in a direction in which the blade member extends, than a tip end of the lower holder is. The tube adjusts a pressing force, of the tip end of the blade member, against the roller by being expanded or contracted while being held by the tube positioning part and the blade member.

A printing apparatus applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink to a substrate. The printing apparatus includes: an image recording section that applies the ink to the surface of the printing plate; a plate surface observation unit that acquires information about the surface of the printing plate; a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate; and a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape.

The invention relates to a method of producing three-dimensional structural surfaces based on synthetic resin-impregnated materials applied to the surface, in particular of wood-based panels. The method is characterized in that before the impregnation, at the stage of pattern printing, a mixture is applied to the decor paper, consisting of printing ink, whether with pigment or not, and a swelling agent in the form of microspheres, being encapsulated gas bubbles of sizes ranging from 2 pm to 180 pm, increasing its volume under the influence of rising temperature, wherein the mixture of the ink and the swelling agent contains from 0.3% to 45% by weight of the swelling agent, and after exiting the printing press and after the impregnation, the decor paper with the formed final pattern with a coded three-dimensional structure is pressed onto the surface, in particular of a wood-based panel, using a heated press plate with any working surface.

A process for providing indicia and an elastic-like behavior to a web substrate is disclosed. The process comprises the steps of: providing a web substrate; printing indicia on the web substrate; and, providing the web substrate with a plurality of first regions and a plurality of second regions comprising the same material composition. A portion of the first regions extend in a first direction while the remainder of the first regions extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions comprise a plurality of raised rib-like elements. The first regions undergo a molecular level and geometric deformation and the second regions initially undergo a substantially geometric deformation when the web material is subjected to an applied elongation along at least one axis.

Systems and methods are directed towards generating a verified unique watermark. More specifically, the systems and methods are directed towards generating a watermark that is as long as possible without any repetition. Such watermarks are possible by selecting characteristics of the watermark and methods for producing the watermarks (e.g., dandy rollers). By producing longer unique watermarks, users would be capable of generating longer rolls of paper whereby more sheets can be produced that each possesses a unique watermark. With the unique watermark, users can identify what information is printed on each sheet as well as authenticate the contents of each individual sheet.

There is described an intaglio printing press (1; 1*) comprising a plate cylinder (8) carrying one or more intaglio printing plates, the plate cylinder (8) receiving ink from an inking system (9, 20, 23; 20*, 23*) having a plurality of chablon cylinders (23; 23*) transferring ink directly or indirectly onto the plate cylinder (8), the intaglio printing press (1; 1*) comprising an adjustment system acting on the chablon cylinders (23; 23*) in order to compensate elongation of the one or more intaglio printing plates. The adjustment system comprises, for each chablon cylinder (23; 23*), an adjustable drive unit, which adjustable drive unit (25) is interposed between the chablon cylinder (23; 23*) acting as a rotating output body of the adjustable drive unit (25) and a driving gear (100) acting as a rotating input body of the adjustable drive unit (25). The adjustable drive unit (25) is designed to allow selected adjustment of a rotational speed of the chablon cylinder (23; 23*) with respect to a rotational speed of the driving gear (100). In an adjusting state of the adjustable drive unit (25), driving into rotation of the chablon cylinder (23; 23*) is adjusted over each revolution of the chablon cylinder (23; 23*) by means of an adjustment motor (300) of the adjustable drive unit (25). In a non-adjusting state of the adjustable drive unit (25), the adjustment motor (300) is inoperative and driving into rotation of the chablon cylinder (23; 23*) is performed exclusively mechanically via the adjustable drive unit (25), the chablon cylinder (23; 23*) rotating at a same rotational speed as the driving gear (100).
