Abstract
To control the amount of ink transferred between an ink application cylinder (2) and an ink supplying cylinder (1) having a cellular surface, such as an anilox roller or another roller or cylinder having ink receptor cells and/or a further cylinder (3) such as a plate cylinder, the ink application cylinder (2) is formed with a yieldingly compressible surface and the yieldingly compressible surface is pre-compressed by application of a surface compression roller (4) thereagainst. The surface compression roller (4) deforms the yieldingly compressible surface (14) which does not expand instantaneously; it may be located in advance of engagement with the ink supplying cylinder (1) or with the plate cylinder (3) by a distance shorter than the decay distance of the compression effected by the surface compression roller. A plurality of such pre-surface compression rollers may be provided, located axially adjacent each other, to control the amount of ink being transfered to the plate cylinder in axially adjacent zones.
