Abstract: 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.

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: Provided is a single-motor-driven gravure cylinder chuck mechanism that is enhanced in contact tightness of chuck cones with respect to an unprocessed plate-making roll in each processing unit of a fully automatic plate-making system. The gravure cylinder chuck mechanism is to be used for a processing unit of the fully automatic gravure plate-making processing system for manufacturing a plate-making roll by performing a series of processes on an unprocessed plate-making roll. The gravure cylinder chuck mechanism includes: a pair of chuck cones provided to be opposed to each other, for chucking both end surfaces of the unprocessed plate-making roll; chuck cone moving means for allowing the pair of chuck cones to be freely brought into contact with and separated away from both the end surfaces of the unprocessed plate-making roll; and a single motor for driving the chuck cone moving means. The single motor allows the pair of chuck cones to be freely brought into contact with and separated away from both the end surfaces of the unprocessed plate-making roll so that the pair of chuck cones chuck the unprocessed plate-making roll.
