Offset printing machine - has double moisture applying system to maintain constant ratio of moisture to ink

摘要

The offset printing machine has a plate cylinder (1) supplied with ink and with a moistening medium so that the ratio of ink to moistening medium is constant. This requirement is achieved by a primary moisture applicator (9) and an additional moisture applicator (10). This additional moisture applicator consists of an inking cylinder (8) which rotates in contact with the third and fourth ink applying rollers (4,5). This method of controlling the ratio of moisture to ink improves the quality of the printing. USE - Offset printing machines.
