Title:
Toppan Printing device
Document Type and Number:
Japanese Patent JP6167789
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a letterpress printing device capable of increasing viscosity to a set value quickly without supplying an ink raw material when film thickness is changed to be thicker in printing step replacement in printing of a high functional material and the like using a volatile solvent.SOLUTION: The letterpress printing device comprises: a press cylinder 105; a substrate machine platen 106; an ink supply device 100; and an ink viscosity control part 200. The ink viscosity control part 200 has an ink viscosity control tank 201, and the ink whose viscosity is controlled is circulated between the ink supply device 100 and the ink viscosity control tank 201, thereby controlling the ink viscosity in the ink supply device.
