Abstract:
1. A line image forming method, comprising the steps of: ejecting a plurality of droplets of liquid sequentially from an inkjet head, the liquid containing a functional component; and depositing the droplets of the liquid onto a non-permeable medium, the deposited droplets becoming joined together on the non-permeable medium to form a line pattern of the liquid, wherein a receding contact angle of the liquid with respect to the non-permeable medium being not larger than 10°, wherein the liquid is configured to be cured by irradiation of an activating light beam, wherein, in the ejecting step the inkjet head is controlled in such a manner that a subsequent droplet to be combined with an aggregate of a group of droplets having been previously deposited on the non-permeable medium is deposited onto the non-permeable medium before the aggregate of the group of previously deposited droplets reaches a state of equilibrium on the non-permeable medium, wherein the line image forming method further comprises the step of curing the liquid deposited on the non-permeable medium by irradiating the activating light beam onto the liquid on the non-permeable medium, and wherein in the curing step, a time T (s) from depositing of a last deposited droplet forming the line pattern until curing of the line pattern is controlled to satisfy: where θ (rad) is a static contact angle of the liquid with respect to the non-permeable medium.
