Abstract

PURPOSE:To vary gradation continuously and smoothly by a system wherein a dot matrix is recorded using ink different in concentration thereof and one or more dots with ink of low concentration are made to exist all over a range of the gradation. CONSTITUTION:A head part 7 of an ink jet printer is provided with three ink heads 14, 15, 16 having discharge ports different in diameter, respectively. The ink head 14 having the smallest discharge port is supplied with ink of low concentration from an ink tank 17, while ink heads 15, 16 having the larger discharge ports are supplied with ink of higher concentration from an ink tank 19. Then, voltages applied to the three ink heads 14, 15, 16 are controlled in accordance with concentration levels, thereby to change the diameter and number of dots to be recorded in a dot matrix. On this occasion, at least one dot with ink of low concentration is made to exist all over a range of concentration level, so that gradation is varied smoothly.
