PRINTING DEVICE AND PRINTING METHOD

摘要

An object of the disclosure is to perform printing in an inkjet printer by a more appropriate method in a case of using ultraviolet curing ink. As a solution, a printing device includes a head unit for ejecting ink drops of ultraviolet curing ink onto a medium, and a controller. The head unit performs a main scan operation corresponding to each of a predetermined N of printing passes (wherein N is an integer of three or greater) on the same area of a medium in a multi-pass mode, and the controller sets a density of printing to be performed in the last k printing passes (wherein k is an integer which is equal to or greater than 1 and is less than N), so as to be lower than a density of printing to be performed in the (N-k)-th printing pass, and sets a density of printing to be performed by a plurality of individual nozzles of the nozzle row of the head unit for ejecting ink drops in the (N-k+1)-th printing pass, so as to gradually decrease toward a head rear end side.
