PROBLEM TO BE SOLVED: To provide a turntable type UV multicolor printing equipment, with which the whole surface of a printed surface is uniformly cured by a method wherein converging type illuminators are employed as UV illuminators under a state that UV intensity is enlarged by setting the focal length of the illuminator smaller and UV irradiation is performed by translating either one of the UV illuminator and a printed matter in parallel to each other in order to print double or the like with special UV ink. SOLUTION: Along the peripheral part of the turntable 1, pallets 3, on each of which the printed matter 2 is placed for conveyance, are equipped equiangularly so as to intermittently turn the turntable every installation angle of the pallet. Above the turntable and at the positions corresponding to the pallets, the number, which corresponds to the number of printing colors, of presses 4 and of the UV irradiators 5 are arranged alternately. As the UV illuminator 10 of the UV irradiator, the converging type appliance 11 having a short focal length equipped with an UV lamp 12 is employed. At the same time, under the state that the focal point F of the UV of the UV illuminator is nearly brought in line with the printed surface 2a of the printed matter 2, the UV illuminator is translated parallel to the printed surface.
