Abstract
The supply of a negative pressure to an opening P(+) adjacent to an opening P() is stopped by switching a suction valve connected to the opening P(+) from an open state to a closed state while keeping a positive pressure valve connected thereto closed. Then, near the opening P(+), a force for holding a blanket becomes gradually weaker against a pressure force in a pressurized space. Associated with that, an air component in the pressurized space flows into a space between a portion of the blanket vertically above the opening P(+) and an upper surface, whereby the blanket portion is lifted from the upper surface and brought into contact with the lower surface of a printing plate. In this way, a contact area is slowly and stably widened while a sudden change of a pressure in the pressurized space SPis suppressed.
