Before printing an electronic circuit onto the printable material at the contact point (I) between a rubber cylinder (2) and an impression cylinder (3), the present invention images a region containing the register mark (RM2) by using an FF camera (305), and detects the position of the register mark (RM2) on the basis of the captured image. On the basis of the position of two register marks (RM2) added to two consecutive printable materials, the present invention obtains the distance between the register marks (RM2), and adjusts the rotation speed of the rubber cylinder (2) according to the distance. As a result, it is possible to accurately align the positions of the circuit from the first printing and the circuit from the second printing, regardless of the degree of stretch in the substrate.
