PROBLEM TO BE SOLVED: To provide an ink-jet printer capable of producing a thick film printed matter of a minute, clear and sharp image regardless of the kind of the printing medium using a low viscosity ink suitable for ink jetting by an ink-jet recording head. SOLUTION: An ink-jet printer for printing on a sheet of printing paper 3 by jetting an ultraviolet ray hardening type ink from an ink-jet recording head 5 onto the printing paper 3, provided with an ultraviolet ray irradiation device A comprising an ultraviolet ray generating part 10 for generating an ultraviolet ray, and optical fibers 11a, 11b for guiding the ultraviolet ray generated by the ultraviolet ray generating part 10 to a position in the vicinity of the ink-jet recording head 5 such that the ultraviolet ray is provided from the tip end of the optical fibers 11a, 11b for executing thick film printing by repeating an ink jetting step of jetting the ultraviolet ray hardening type ink onto the printing paper 3 by the ink-jet recording head 5 and an ink hardening step of hardening the ultraviolet ray hardening type ink impacted on the printing paper 3 by the ultraviolet ray irradiation device A immediately after the ink jetting step, is provided. |
