Title
(EN) LIQUID EJECTION DEVICE, PROGRAM AND EJECTION CONTROL METHOD
(FR) DISPOSITIF D'ÉJECTION DE LIQUIDE, PROGRAMME, ET PROCÉDÉ DE COMMANDE D'ÉJECTION
Abstract
(EN)
A liquid ejection device includes: a move control unit configured to move any one of a first element and a second element in a main-scanning direction and a sub-scanning direction orthogonal to the main-scanning direction, the first element including a plurality of ejectors to eject active energy ray curable liquid and an active energy ray irradiator, the second element including an object to which the liquid is ejected; and a control unit configured to perform control to cause a first ejector to eject a first ejection amount of liquid, cure the first ejection amount of liquid, cause a second ejector to eject a second ejection amount of liquid onto the cured first ejection amount of liquid, and cure the second ejection amount of liquid. The first ejection amount and the second ejection amount are different from each other.
(FR)
L'invention concerne un dispositif d'éjection de liquide comprenant : une unité de commande de déplacement configurée pour déplacer l'un quelconque d'un premier élément et d'un second élément dans une direction de balayage principal et une direction de sous-balayage orthogonale à la direction de balayage principal, le premier élément comprenant une pluralité d'éjecteurs pour éjecter un liquide durcissable par rayonnement d'énergie active et un irradiateur de rayonnement d'énergie active, le second élément comprenant un objet auquel le liquide est éjecté; et une unité de commande configurée pour effectuer une commande pour amener un premier éjecteur à éjecter une première quantité d'éjection de liquide, durcir la première quantité d'éjection de liquide, amener un second éjecteur à éjecter une seconde quantité d'éjection de liquide sur la première quantité d'éjection de liquide durcie, et durcir la seconde quantité d'éjection de liquide. La première quantité d'éjection et la seconde quantité d'éjection sont différentes l'une de l'autre.
