An electronic circuit board manufacturing method according to the present disclosure is a method of manufacturing an electronic circuit board including a substrate and an electronic circuit having a predetermined pattern, the electronic circuit being fixed on the substrate and being made from a nanoink composition containing metal particles. The method includes the steps of: causing a printing plate to hold a nanoink composition containing metal particles, the printing plate including an ink holding part formed on a surface thereof and having a predetermined pattern; bringing a surface of the substrate into intimate contact with the printing plate to transfer the nanoink composition held on the ink holding part onto the substrate; and drying the transferred nanoink composition in an environment of 40° C. or below in the atmosphere to fix the nanoink composition after the transfer step, thereby forming an electronic circuit having a predetermined pattern.

A printing method according to the invention comprises forming a printing pattern of ink on a surface of an intermediate transfer member, transferring the printing pattern by causing the printing target surface to abut on the surface of the intermediate transfer member while supporting the printing target material by making a backup member abut on the printing target surface, increasing viscosity of the ink to predetermined viscosity by irradiating the printing pattern transferred to the printing target surface with first light, and curing the ink by irradiating the printing pattern with second light. The first light is applied to a region, out of the printing target surface, in a state that after departing from the intermediate transfer member and before abutting on the backup member. The second light is applied while the printing target material is separated from the intermediate transfer member.

A gravure printing device includes a substrate stage (11) on which a substrate (2) is fixed, an intaglio plate (21) for holding conductive paste, and a control device (7) for controlling a series of printing operations including a supply operation of supplying conductive paste (3) to a printing pattern of the intaglio plate (21) and a transfer operation of transferring the conductive paste (3) to the substrate (2). The control device (7) repeatedly performs the series of printing operations a plurality of times with respect to the identical printing position on the substrate (2). A printing pattern laminate made of the conductive paste laminated into the shape of the printing pattern is formed on the substrate (2). This makes it possible to form lines and bumps on a substrate made of a heat-sensitive material, while preventing the occurrence of metamorphosis of the substrate made of the heat-sensitive material.

A printing cylinder assembly for a printing machine includes a rotating shaft pivotally supported at one axial end shaft section thereof in a cantilever structure, and a sleeve cylinder removably mounted on the rotating shaft so that the cylinder can be fitted on and extracted from the rotating shaft from the other axial end side of the rotating shaft.
