METHOD FOR FORMING DOTS, METHOD FOR FORMING IDENTIFICATION CODE, AND LIQUID EJECTION APPARATUS
First Claim
1. A method for forming a dot by means of an apparatus having a nozzle for ejecting a liquid droplet onto a substrate and laser radiation means, the dot is formed by radiating a laser beam from the laser radiation means to the liquid droplet to dry the liquid droplet,wherein the timing for radiating the laser beam to the liquid droplet that has been ejected from the nozzle is controlled depending on the velocity at which the nozzle is displaced relative to the substrate.

Abstract
An acceptable duration is defined as the time necessary for allowing the diameter of a microdroplet that has reached the substrate to become a maximum acceptable droplet diameter. A scanning speed is set in such a manner that the microdroplet that has been received by the substrate reaches a radiating position from a droplet receiving position immediately after the acceptable duration has passed since reception of the microdroplet by the substrate. A laser beam is radiated onto the microdroplet immediately after the acceptable duration has passed since the reception of the microdroplet Fb by the substrate, or when the microdroplet is located at the radiating position.
