LIQUID DROPLET DEPOSITION METHOD AND LIQUID DROPLET DEPOSITION APPARATUS
A liquid droplet deposition method of consecutively depositing a plurality of droplets of liquid, which contains solvent and particles dispersed in the solvent and having a substantially uniform size, onto a recording medium includes the steps of: determining target positions at which the plurality of droplets are to be deposited on the recording medium; depositing an X-th droplet of the droplets at an X-th target position of the determined target positions on the recording medium, X being a natural number; and depositing an (X+1)-th droplet of the droplets at an (X+1)-th target position of the determined target positions on the recording medium subsequently to the X-th droplet, after the particles contained in the X-th droplet are aggregated to form an X-th particle aggregate on the recording medium due to liquid bridging force, wherein in the determining step, the target positions are determined so as to satisfy following conditions: L(CX,CX+1)rX+r_maxX+1, and L(PX,CX+1)r_maxX+1, where CX is the X-th target position, CX+1 is the (X+1)-th target position, L(CX, CX+1) is a distance between CX and CX+1, rX is a radius of the solvent of the X-th droplet on the recording medium at a time of depositing the (X+1)-th droplet on the recording medium, r_maxX+1 is a radius of the solvent of the (X+1)-th droplet at a time of maximumly spreading on the recording medium, PX is a position of an edge of the X-th particle aggregate on a line connecting CX and CX+1, and L(PX, CX+1) is a distance between PX and CX+1.
