Printing apparatus, line printer and method for printing

A line printer comprising:

• a head section having a plurality of nozzle rows formed by a plurality of lines of nozzles each being configured to emit photocurable ink to be hardened upon being irradiated with light onto an image forming area of a target for printing, the head section having an irradiation section configured to irradiate the target for printing with the light;
• a moving section configured to relatively move the head section with respect to the target for printing in a crossing direction which crosses a line direction of the nozzle rows;
• and
• a controller configured to carry out control so as to emit the photocurable ink from the nozzles onto the image forming area of the target for printing having relatively moved by means of the moving section, the controller being configured to control the head section so as to irradiate the photocurable ink having impacted on the image forming area from the irradiation section with the light, wherein
• the controller controls irradiation energy of the light that the irradiation section irradiates the image forming area with so that irradiation energy of the light that an edge area of the image forming area is irradiated with is smaller than irradiation energy of the light that an area of the image forming area adjacent to the edge area is irradiated with.

A method for printing an image on a target for printing by means of a printing apparatus including a head section having a nozzle row formed by a plurality of lined up nozzles each being configured to emit photocurable ink to be hardened upon being irradiated with light onto the target for printing, the head section having an irradiation section configured to irradiate the target for printing with the light, the method comprising:

• moving the head section with respect to the target for printing relatively in a crossing direction which crosses a direction of the lined up nozzles forming the nozzle row;
• emitting the photocurable ink from the respective nozzles in the nozzle row onto an image forming area of the target for printing;
• and
• irradiating the photocurable ink having impacted on an area adjacent to an edge area of the image forming area and having impacted on the edge area by means of the emission of the photocurable ink with the light of first irradiation energy from the irradiation section and of second irradiation energy which is smaller than the first irradiation energy, respectively.
