<P>PROBLEM TO BE SOLVED: To provide a liquid droplet ejector that prevents ink landed on a recording medium from being misaligned and prevents image quality from degrading, which achieves excellent printing quality. <P>SOLUTION: The liquid droplet ejector includes: a liquid ejection head 9 which ejects ink cured by an ultraviolet ray; an ultraviolet ray irradiator 12 which emits an ultraviolet ray to cure the ink; a stage 6 on which a recording medium P is mounted; a carrier which carries the head 9 and the stage 6 relatively each other; and a temperature detector 40 which detects a distribution of the temperatures of the medium P; a determiner which calculates temperatures of predetermined unit regions for ejection based on the distribution and then determines if these calculated temperatures are less or equal to the predetermined temperatures; and a control which controls the carrier to prepare the ejection of the ink from the head 9 to the regions whose temperatures are determined to be less or equal to the predetermined temperature based on the results determined by the determiner. <P>COPYRIGHT: (C)2012,JPO&INPIT |
