An inkjet printing apparatus suppresses air currents heading toward print head faces, and reduces the adherence of ink mist onto the print heads. The apparatus includes a carriage upon which is mounted one or more print heads with ink ejection ports formed thereon, a printing unit that prints an image onto a printing medium by causing ink droplets to be ejected toward the printing medium from the ink ejection ports while also causing the carriage to move with respect to the printing medium, and an airflow control mechanism formed on the surface of the one or more print heads or the carriage that faces the printing medium, the airflow control mechanism controlling air currents flowing into a lateral region extending along the carriage moving direction on either side of the region where the ink ejection ports are formed, and causing the air pressure to rise in the lateral region.

Inkjet printing apparatus

There is provided an inkjet print apparatus which can prevent floating mists from being attached on a head face to realize a print with high quality. Therefore a wing-shaped print head is provided to increase an air flow flowing into a region between a print head positioned backward thereof and a print medium.

Inkjet print head and inkjet print apparatus

An inkjet printing apparatus which enables printing with high print quality is provided. For that purpose, a pair of airflow guides are provided at intermediate positions between each adjacent two of the printing heads arrayed in a travelling direction of a carriage, the pair of the airflow guides respectively located right and left in a direction perpendicular to the travelling direction of the carriage.
