A printer , comprising: a head unit that ejects a photo-curable ink as ink dots; a light irradiation device that irradiates the photo-curable ink with a light; and a controller programmed to control a rate of ejection of the photo-curable ink and a standby time between a timing of the photo-curable ink landing on a print medium and a timing of the light being radiated, the controller being characterized by comprising: a first controller that prompts the printer to carry out a printing operation to form ink dots by a first rate of ejection required of glossy-finish printing and with a first standby time t1 required of glossy-finish printing; a second controller that prompts the printer to carry out the printing operation to form ink dots by a second rate of ejection required of matte-finish printing and with a second standby time t2 required of matte-finish printing; and a third controller that prompts the printer to carry out the printing operation to form ink dots by a third rate of ejection and with a third standby time t3, the rate of ejection being greater than the second rate of ejection and less than or equal to the first rate of ejection, the third standby time t3 being shorter than the first standby time t1, the rate of ejection satisfying the relationship of: the second rate of ejection < the third rate of ejection ≤ the first rate of ejection. a head unit that ejects a photo-curable ink as ink dots; a light irradiation device that irradiates the photo-curable ink with a light; and a controller programmed to control a rate of ejection of the photo-curable ink and a standby time between a timing of the photo-curable ink landing on a print medium and a timing of the light being radiated, the controller being characterized by comprising: a first controller that prompts the printer to carry out a printing operation to form ink dots by a first rate of ejection required of glossy-finish printing and with a first standby time t1 required of glossy-finish printing; a second controller that prompts the printer to carry out the printing operation to form ink dots by a second rate of ejection required of matte-finish printing and with a second standby time t2 required of matte-finish printing; and a third controller that prompts the printer to carry out the printing operation to form ink dots by a third rate of ejection and with a third standby time t3, the rate of ejection being greater than the second rate of ejection and less than or equal to the first rate of ejection, the third standby time t3 being shorter than the first standby time t1, the rate of ejection satisfying the relationship of: the second rate of ejection < the third rate of ejection ≤ the first rate of ejection. a first controller that prompts the printer to carry out a printing operation to form ink dots by a first rate of ejection required of glossy-finish printing and with a first standby time t1 required of glossy-finish printing; a second controller that prompts the printer to carry out the printing operation to form ink dots by a second rate of ejection required of matte-finish printing and with a second standby time t2 required of matte-finish printing; and a third controller that prompts the printer to carry out the printing operation to form ink dots by a third rate of ejection and with a third standby time t3, the rate of ejection being greater than the second rate of ejection and less than or equal to the first rate of ejection, the third standby time t3 being shorter than the first standby time t1, the rate of ejection satisfying the relationship of: the second rate of ejection < the third rate of ejection ≤ the first rate of ejection. <EOS>
