A print pattern of a printing plate used in intaglio printing includes plural partition walls and a groove-shaped cell unit. The plural partition walls are continuously extended in a printing direction, and arranged at predetermined intervals in an orthogonal direction. The cell unit is formed between the partition walls adjacent to each other, and a printing paste (conductive paste) is retained in the cell unit. Plural printing direction walls that are arranged in a zigzag manner in the printing direction are coupled to each other by a coupling walls that are arranged in the printing direction walls adjacent to each other in the printing direction, thereby forming the partition wall.

The present invention relates to using soft secondary plates and specialty inks in a printing process. More specifically, the present invention relates to an apparatus and methods of using soft secondary plates made of a rubber comprising a saturated chain of polymethylene or a photopolymer material to decorate an exterior surface of cylindrical metallic containers with high definition graphics and other indicia.

Disclosed is a multilayer film for packaging. The multilayer film has a layer of ink and an adjacent layer of substrate. The layer of ink includes functionalised graphene and a material selected from cellulose, polylactic acid and a polyhydroxyalkanoate.

An article with an operative liquid-bearing surface is adapted for transferring that liquid to a substrate material or printing plate. The entire operative surface of the article is provided with a pattern of microscopic discrete depressions which are usually laser-engraved into the surface so that a substantially continuous wall structure remains which surrounds and defines the depressions. In particular the depressions are of a cross-sectional shape which is symmetrical about one or both of a lateral and a medial axis perpendicular thereto, and arranged adjacent one another in offset fashion, and above and below one another so that the pattern thus formed is substantially uniform and repeating. Each of at least one of the pairs of lateral or medial sidewalls of any one depression are contoured, the contour of one of the pair being generally the mirror image of the other.

Provided are an offset printing plate, an offset printing apparatus, and an offset printing method, which are capable of printing a high-definition image by waterless offset printing.

The offset printing plate comprises: a cylindrical plate base material; a silicon resin layer formed on the cylindrical plate base material; and a resist pattern part formed on the silicon resin layer, in which the silicon resin layer serves as a non-printing area, and the resist pattern part serves as a printing area. The silicon resin layer is preferably formed on the cylindrical plate base material seamlessly.

An object of the present invention is to provide a flexographic printing plate precursor which has few mask defects, is unlikely to contaminate an apparatus during development, and is capable of obtaining a flexographic printing plate having excellent concave line reproducibility and being unlikely to cause ink entanglement; and a manufacturing method of a flexographic printing plate using the flexographic printing plate precursor. The flexographic printing plate precursor of the present invention is a flexographic printing plate precursor including, at least, in the following order, a support, a photosensitive resin layer, and a heat-sensitive image forming layer, in which the heat-sensitive image forming layer contains a pigment as an infrared absorber and a dye as an ultraviolet absorber, and an optical density of the heat-sensitive image forming layer is 3.0 or more.

A flexographic printing raw plate comprising at least a support, a photosensitive resin composition layer, an intermediate layer, and an infrared ablation layer sequentially stacked, wherein the intermediate layer comprises a hydrophilic resin (A) and a layered inorganic compound (B), and the intermediate layer has a film thickness of 2 ?m or more and 30 ?m or less.

Disclosed is a waterless planographic printing plate precursor including at least a substrate, a heat sensitive layer and an ink repellent layer in this order, wherein the substrate has a white color layer or a white color surface, and wherein the heat sensitive layer includes at least (a) an infrared-absorbing dye having a maximum absorption wavelength of 700 to 1,000 nm, (b) a dye that changes color by proton acceptance, and (c) a proton-donating compound. The present invention provides a waterless planographic printing plate precursor capable of obtaining high contrast between the image area and the non-image area by exposure without the need for a special layer.
