Abstract: A gravure printing roll that enables printing of fine dots with a size close to that of cells and enables printing on a print subject, such as a printing substrate, without changing the appearance of the print subject. The gravure printing roll includes: a gravure printing roll body; and cells formed in a peripheral surface of the gravure printing roll body. Each of the cells has an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body (dimension in the circumferential direction/dimension in the axial center direction) being 1.15 to 7, and have an opening area of 3900 μm2 or smaller.

Abstract: The present invention provides a coating material that can improve gravure printing characteristics of the printing surface of a printing substrate to favorably transfer an ink fed in the cell of a gravure printing roll to the printing surface of the printing substrate, thereby achieving the beautiful gravure printing. The coating material of the present invention is a coating material for forming a surface layer, serving as a printing surface, on a printing substrate on which gravure printing is to be performed, and the coating material is characterized by including a vinyl chloride-vinyl acetate-unsaturated fatty acid copolymer that includes 80 to 90% by mass of a component of vinyl chloride, 9.2 to 19.5% by mass of a component of vinyl acetate, and 0.1 to 0.8% by mass of a component of an unsaturated fatty acid.

Abstract: The present invention provides a coating material that can improve gravure printing characteristics of the printing surface of a printing substrate to favorably transfer an ink fed in the cell of a gravure printing roll to the printing surface of the printing substrate, thereby achieving the beautiful gravure printing. The coating material of the present invention is a coating material for forming a surface layer serving as a printing surface on a printing substrate to which gravure printing is to be applied, and the coating material is characterized by including a pigment including an inorganic particulate and a skin layer that is formed on a surface of the inorganic particulate and includes an organic compound.
