Double-sided stencil printing apparatus

Abstract

A double-sided printing apparatus using a double sided printing with one plate cylinder and one pressing means system, that is capable of carrying out double-sided printing simply and at low cost, with little deviation in the position of the printed image and with satisfactory resist. Printed matter with little deviation of the image position with respect to the sheet position and with good resist can be obtained, by eliminating delay in feeding sheets due to slippage between roller and press roller by operating the transport belt on the upstream side, and so on, and by eliminating resistance during sheet transportation due to contact with the guide member provided along the circumferential surface of the press roller, when pressing sheets against the press roller with a roller or the like, and transporting the sheets along the guide member or the like provided along the peripheral surface of the press roller. After the resist roller has eliminated the contact between the sheet and the stopper, the transport belt starts to be driven. If the printing speed is low, this timing is taken as the timing that the resist roller contacts the press roller. For both low speeds and high speeds, this may be after passage of a predetermined period of time from the operation command signal for the resist roller.
