摘要： The present invention relates to an ink-jet printing method that is capable of obtaining good printed materials that are free of occurrence of color migration and deformation of a printing medium even when printed on a resin printing medium. The present invention provides an ink-jet printing method using a water-based ink containing a black ink, a chromatic ink and a white ink which each contain a pigment (A), an organic solvent (C) having a boiling point of not lower than 90° C. and lower than 250° C., and water, said method including step 1 of ejecting at least one water-based ink selected from the group consisting of the black ink and the chromatic ink onto a transparent resin printing medium to print an image 1 on the printing medium; step 2 of ejecting the white ink onto the resulting image 1 to print a white image that covers the image 1 on the printing medium; and step 3 of heating and drying the resulting printed material from a side of a surface of the printing medium on which the white image is formed, using an infrared heater.

摘要： 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.

摘要： Provided are a roll polishing rotary grinding stone and a roll polishing device and method which are configured to stably perform roll polishing without making the surface roughness of a surface to be processed non-uniform by preventing polishing debris to be generated during polishing from being accumulated in a recess at a center of a polishing surface of the roll polishing rotary grinding stone body. The roll polishing rotary grinding stone includes: a rotary grinding stone body having a rotary shaft mounted on a back end face and a polishing surface formed on a front end face; and a recess formed at a center of the front end face of the rotary grinding stone body, the roll polishing rotary grinding stone being configured to perform vertical polishing with respect to a surface of a roll by bringing the polishing surface into contact with the surface of the roll, in which the recess is formed into a tapered recess in which an inner peripheral surface of the recess is increased in diameter from the back end face of the rotary grinding stone body toward the front end face of the rotary grinding stone body.
