Title:
Liquid discharge head, liquid discharge head manufacturing method, and liquid discharge head manufacturing system
Document Type and Number:
Japanese Patent JP6342855
Kind Code:
B2
Abstract:
The liquid ejection head (21) has a structure in which three or more head modules (200) including a plurality of ejection elements (281) are arranged along a single direction, and the liquid ejection head (21) includes a first head module (200B), a second head module (200C) and a third head module (200D) which are arranged in ascending order of slope of ejection volume distribution in the single direction or are arranged in descending order of the slope of the ejection volume distribution in the single direction, the slope of the ejection volume distribution in the single direction being evaluated by subtracting an ejection volume at one end part in the single direction from an ejection volume at the other end part in the single direction.
