ンキ戻し機構。(1) An ink permeable part is provided on the peripheral wall of the printing drum, which is formed in a mesh shape with a large number of holes that allow ink to pass through, and printing base paper is pasted on top of the ink permeable part, so that the ink can be injected from the inside of the printing drum. In a rotary printing machine that presses the printing paper against the printing base paper using a press roller to perform printing, the press roller moves the printing paper from the printing base paper onto the printing drum without making one revolution. The printing drum is made to protrude radially outward at a position opposite to the end of the printing base paper to be transferred, and a strip of constant width is formed running in the axial direction of the printing drum, and a strip of constant width is formed on the protrusion for returning ink. An ink return mechanism for a rotary printing press, characterized in that an ink return section consisting of a large number of holes is provided, and the ink is returned from the ink return section to the printing drum by a force acting on the protrusion from a press roller.
