Abstract
A printing device includes a discharge head, an irradiation unit and a controller. The discharge head is configured and arranged to discharge droplets of a liquid curable by active rays onto a substrate while the discharge head and the substrate move relative to each other. The irradiation unit is configured and arranged to radiate the active rays to the droplets on the substrate. The irradiation unit is provided behind the discharge head with respect to a direction of a relative movement. The controller is configured to turn off the irradiation unit when a predetermined time has elapsed since start of lighting of the irradiation unit.
Claims5
A printing device comprising:
- a discharge head configured and arranged to discharge droplets of a liquid curable by active rays onto a substrate while the discharge head and the substrate move relative to each other;
- an irradiation unit configured and arranged to radiate the active rays to the droplets on the substrate, the irradiation unit being provided behind the discharge head with respect to a direction of a relative movement;
- and
- a controller configured to turn off the irradiation unit in response to the controller determining that a predetermined time has elapsed since start of lighting of the irradiation unit, with the predetermined time corresponding to a time period needed for the irradiation unit to relatively pass over an entire length of the substrate in the direction of the relative movement.
