Document Type and Number:
WIPO Patent Application WO/2021/200117
Kind Code:
A1
Abstract:
In order to provide an inkjet printing device capable of continuing printing during a speed change of a continuous paper WP, a conveyance control unit 31 according to the present invention controls driving rollers 7, 9, 11, and 13 so that a speed difference that is a difference between a first speed representing a conveyance speed of the continuous paper WP when an upstream side nozzle ejects an ink droplet and a second speed representing a conveyance speed of the continuous paper WP when a downstream side nozzle ejects an ink droplet becomes constant at respective time points during speed changes of the driving rollers 7, 9, 11, and 13. Thus, a relationship between a landed position on the continuous paper WP of the ink droplet relating to the upstream side nozzle and a landed position on the continuous paper WP of the ink droplet relating to the downstream side nozzle can be made constant at the respective time points during the speed changes of the driving rollers 7, 9, 11, and 13.
