Abstract
The invention relates to a recording apparatus which includes a plurality of line heads that discharge light curable inks onto a recording target material, a plurality of first light irradiators that are located at downstream side of transportation direction relative to the respective line heads in the transportation direction and emit light to the recording target material, a drum that is located at the downstream side relative to the first light irradiators in the transportation direction and forms a part of the transportation path, and a second light irradiator that is located opposite to a portion of the drum with which the transported recording target material makes contact and emits light to the contact portion. In the recording apparatus, the first light irradiators emit light for provisionally curing the discharged light curable inks, and the second light irradiator emits light for permanently curing the light curable inks, which have been provisionally cured, on the drum.
Description
technical field [0001] The present invention relates to a recording apparatus having a plurality of line heads that are spaced apart in a conveyance direction along a conveyance path and eject photocurable ink onto a recording material. Background technique [0002] As a conventional recording device, the device described in Patent Document 1 can be cited. In this patent document 1, there is described a printing device in which ultraviolet curable ink is printed on an object to be printed by a print head, and the printing device is separately installed downstream of the print head in the transport direction. A printing device that cures the printed image by irradiating ultraviolet rays to the guide roller portion on the side. There is also described a printing device that cures a printed image by irradiating ultraviolet rays in an area downstream of the guide roller. [0003] Since in the conventional recording device, the print head and the ultraviolet rayirradiation pos...
