Abstract:
1. A printing device for discharging ink from a print head onto a print medium to print an image, the printing device comprising: an input unit configured to input image data constituting the image; a detection unit configured to detect pixels constituting at least a high-concentration side of an edge of the image as edge pixels based on the inputted image data; a halftone processing unit configured to create dot data expressing whether or not dots are formed based on the image data; and a printing unit configured to print the image by combining together dots formed at a forward-movement and a backward-movement in a common print region of the print medium based on the dot data, the halftone processing unit being configured to create the dot data so that, in positions on the print medium where dots corresponding to the edge pixels are formed, the dots are formed disproportionately at one of the forward-movement and the backward-movement.
