ABSTRACT:
An inkjet print device prints by reciprocally moving a carriage (15) in a main scan direction while controlling ink ejection from a print head (17) according to information on the position of the carriage (15) both in a forward movement and in a return movement. An encoder (22), a first U/D counter (29), a second U/D counter (30), a timer (31), and an interval timer (32) senses the position of the carriage (15). The encoder (22), the first U/D counter (29), and the timer (31) senses the speed of the carriage (15). A TBL memory (33) is used in determining a positional correction quantity at a sensed carriage speed from a positional correction quantity at a predetermined carriage speed. A head control section (26) controls ink ejection from the print head (17) based on the carriage position and the positional correction quantity.
