Liquid drop ejecting device, controller therefor, liquid drop ejecting method, and storage medium storing a program

Abstract

A controller for a liquid drop ejecting device including a first head with plural first liquid drop ejectors, and a second head with plural second liquid drop ejectors, is provided. The controller includes: a scanning controlling section scanning at least the first head plural times a same region of a recording medium; and an ejection controlling section controlling the first and second head such that a proportion of an applied amount, per unit surface area, of the second liquid drops with respect to an applied amount, per unit surface area, of the first liquid drops in a first scan, is within a range of 0 to a first value, and the proportion in scans from a second scan on is within a range of a second value to 1, and the proportion in the first scan is smaller than the proportion in the scans from the second scan on.
