Abstract
A keyless printing press includes a delivery nozzle disposed in opposition to an ink source roller and provided with a plurality of delivery ports aligned in parallel along the axial direction of the ink source roller. Printing ink circulating through an ink circulation system is delivered and fed through the respective delivery ports of the delivery nozzle to the ink source roller. The arrangement is improved to obviate the shortcoming that isolated water may repeatedly circulate through the ink circulation system and accumulate, resulting in lowering of printing depth. At least one ink outflow port, for ensuring that printing ink having a high moisture content proportion will flow out of the delivery nozzle, is provided in the delivery nozzle at a position at a level higher than any of the delivery ports.
