Title:
INKJET PRINTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/004308
Kind Code:
A1
Abstract:
Printing using ink droplets is performed on continuous paper WP by a first printing device 5, and the ink droplets are dried by a drying unit 25. Next, the continuous paper WP holding heat from the drying unit 25 is cooled by a cooling mechanism 29. When the continuous paper WP is transported by a transportation unit 28, heat at the center part of the continuous paper WP is transmitted to the surface of the continuous paper WP, and the continuous paper WP is cooled, in a state in which the temperature gradient is larger, by a separate chiller unit 9. The continuous paper WP can therefore be cooled by the separate chiller unit 9 in an efficient manner. The continuous paper WP has therefore been sufficiently cooled by the time the continuous paper WP is treated by a second printing device 11, making it possible to prevent the processing by the second printing device 11 from being adversely affected, even when the drying unit 25 is one in which drying of the continuous paper WP has been enhanced.
