Abstract

See full text

A print apparatus carries out printing by allowing an ink and a processing liquid that makes the ink insoluble to deposit on a printing medium in such a way that they are deposited on each other on a printing medium. A head that ejects the ink or processing liquid and the printing medium are relatively moved in a primary scanning direction. A processing liquid droplet and a black ink droplet are sequentially ejected at the same positions in the direction opposite to the relative moving direction from the respective ejection ports provided at a predetermined space in the relative moving direction on the head. This configuration allows a splashing liquid droplet caused by a subsequent black ink droplet depositing on the processing liquid droplet previously depositing on the printing medium at a position, to be ejected in the direction opposite to the relative moving direction of the head and the printing medium, thereby preventing the splashing liquid droplet from splashing on a face of the head to deposit thereon.
