PROBLEM TO BE SOLVED: To provide a double-side working device which enables a printing pressure to be uniformly applied, in the axial direction, during performing a printing or molding process on one of the sides of a base material on the downstream side, following a molding process performed on the other side of the base material on the upstream side. SOLUTION: In the double-side working device which continuously supplies a radiation-curable resin R to a gap between a molding die roll 1 and the base material S and continuously molds a fine pattern, in a large width, on the base material S, and at the same time, continuously prints an image on the side opposite to the molded side of the base material S on the downstream side, using a printing roll 3, a roll of such a shape as to make the printing pressure uniform during printing on the downstream side is used as a molding nip roll 2. Thus, the very slight error of the roll, with a large width and fine pattern, which requires high precision and a gap generated between the molding die roll 1 and the printing roll 3 when these rolls are installed, are absorbed. Consequently, to equalize the printing pressure during printing or molding on the downstream side and reduce the incidence of the irregularities of variable density and missing print are realized.
