The present invention relates to a parallel UV offset printing apparatus having an ultraviolet radiation ray device. More specifically, the present invention relates to the parallel UV offset printing apparatus having the ultraviolet ray radiation device which rapidly hardens a UV ink without thermal strain in case of a printing matter having a thermal strain when the printing matter is radiated by an ultraviolet ray. For the same, in the parallel UV offset printing apparatus where a number of UV offset printers are located in parallel to print the UV ink through a loading part carrying the printing matter, the ultraviolet ray radiation device is arranged to harden the UV ink while being arranged on a rear part of each UV offset printer. In the ultraviolet ray radiation device, an inlet part supplied with cool wind and a discharge part to discharge the inputted cool wind respectively are formed. |
