Ink jet recording apparatus

摘要

In an ink jet recording apparatus having two head units (232, 233), each having a large number of ink nozzles arranged in a line, assembled so that they overlap with each other, an 8-shade image signal is entered into a correction circuit (41) and a line direction position signal is input into a position signal decision circuit (42). When the position signal decision circuit (42) decides that the position signal represents the overlapping zone of the head units, the shade level of the image signal is divided between the head units (232, 233). For example, when the shade level of the image signal is 7, one of the head units is allotted the shade level (6) and the other is allotted the shade level (1). The overlapping nozzles in a pair eject droplets of ink to form one dot.
