Title
(EN) Liquid injection device and liquid injection method
(ZH) 液体喷射装置和液体喷射方法
Abstract
(EN) Streak defects are reduced by making correction for each unit head even if there is variation in jet characteristic of ink droplet among unit heads and even if there is variation in arrangement accuracy of the unit heads. A liquid jet device comprises a line head (10) where (unit) heads (11) having liquid jet portions are arranged are arranged side by side. The liquid jet device further comprises jet direction changing means for changing the direction of jet of a liquid droplet jetted from a nozzle of each liquid jet portion into one of directions parallel to the direction of the arrangement of the liquid jet portions and reference direction setting means for setting one main direction used as a reference out of the jet directions of the liquid droplet changeable by the jet direction changing means individually for each unit head (11). The jet direction of the third liquid jet portion in each of the 'N-1'-th and 'N+1'-th heads (11) is the main direction, and the jet direction of the second liquid jet portion of the 'N'-th head (11) is the main direction.

即使墨滴的喷射特性在单元头之间分散和单元头的配置精度分散,通过与每一单元头相适应的校正可以减轻条纹不均匀性。液体喷射装置包括行头部(10),具有液体喷射部分的(单元)头(11)并置。其还包括:喷射方向改变装置,它可将从每一液体喷射部分的喷嘴喷射的液滴的喷射方向改变为在该液体喷射部分的配置方向平行的一方向;和参考方向设定装置,它可在由该喷射方向改变装置可改变的喷射方向中,单独设定每一单元头的一参考主方向。对第(N-1)个和第(N+1)个头(11)确定第三个喷射部分的喷射方向为主方向,而对第N个头(11)确定第二喷射部分的喷射方向为主方向。
