Method for forming dots, method for forming identification code, and liquid ejection apparatus
First Claim
1. A method for forming a dot by ejecting a liquid droplet onto a dot forming position defined on a substrate and drying the droplet that has reached the dot forming position;
- wherein a laser beam for drying the droplet is radiated onto the dot forming position.

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.

9. A method for forming an identification code pattern with a plurality of dots in a code formation area on a surface of a substrate, wherein data cells are formed by dividing the code formation area, wherein the dots are formed in selected ones of the data cells by ejecting liquid droplets containing a dot forming material onto the selected data cells and drying the droplets in the selected data cells;
wherein a laser beams for drying the droplets are radiated onto the code formation area. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A liquid ejection apparatus having pressurization means that pressurizes liquid retained in a pressure chamber and an ejection port through which a droplet of the liquid is ejected onto a dot forming position defined on a substrate through pressurization of the pressurization means, the apparatus comprising:
-
laser radiation means that radiates a laser beam for drying the droplet that has been received by the substrate;
radiation control means, wherein, when the ejected droplet is received by the substrate, the radiation control means operates the laser radiation means to radiate the laser beam onto the dot forming position when an outer diameter of the ejected droplet reaches a predetermined outer diameter; and
a controller that controls operation of the radiation control means. - View Dependent Claims (18, 19, 20)
