Printer and printing method

摘要

A head of a printer has a nozzle unit for ejecting fine droplets of light curable ink and a light irradiation part for irradiating light to ink ejected onto a base member. In printing an image, distortion information representing a relationship between a density distribution of an image printed on the base member and distortion of the base member by temperature rise caused by irradiation with light from the light irradiation part is prepared and writing data is generated by modifying a target image on the basis of a density distribution of the target image and the distortion information. Ejection of ink from the head is controlled in synchronization with relative movement of the head in accordance with the writing data, and it is possible to accurately print the target image on the base member in consideration of distortion of the base member caused by irradiation with the light.
