Abstract:
An ink-jet printing device according to the present invention includes: first and second nozzles each configured to discharge ink droplets onto a recording medium being conveyed; a calculation unit to calculate a landing position difference on the recording medium being conveyed at a conveyance speed based on first and second conveyance speeds and first and second landing position differences; and a timing control unit to control each of timings of ink droplet discharge from the first and second nozzles based on the landing position difference calculated by the calculation unit. This configuration allows appropriate correction of variance in the landing positions of ink droplets discharged from the nozzles.

Claim (Index 5):
An ink-jet printing method of controlling timings of ink droplet discharge from a first nozzle and a second nozzle each configured to discharge ink droplets onto a recording medium being conveyed, wherein\n conveyance speeds at which said recording medium is conveyed include a first conveyance speed and a second conveyance speed different from said first conveyance speed, a landing position difference is a difference between a landing position of ink droplets discharged from said first nozzle on said recording medium and a landing position of ink droplets discharged from said second nozzle on said recording medium when said recording medium is conveyed at said conveyance speed, a first landing position difference is said landing position difference when said recording medium is conveyed at said first conveyance speed, and a second landing position difference is said landing position difference when said recording medium is conveyed at said second conveyance speed, the method comprising: calculating said landing position difference on said recording medium conveyed at said conveyance speed based on said first conveyance speed, said second conveyance speed, said first landing position difference, and said second landing position difference; and controlling the ink droplet discharge timings of said first and second nozzles based on said calculated landing position difference.
