In an inker for a printing press capable of producing high coating weights as well as low ones, an ink train of at least two roll cylinders (7, 8) transports ink from a reservoir (1) to a printing plate (4), the final roll cylinder (8) is provided with a doctor blade (9) and (preferably with the other rollers of the train) has a surface of rubber or synthetic polymeric or resin material. In use the doctor blade is spaced from the cylinder (8), preferably using a control system for maintaining a predetermined coating weight as measured on the product. The rollers (7, 8) may be vertically or generally horizontally aligned, but the vertical alignment shown can also be used with a hard anilox roll for producing high coating weights. The roll cylinders may be mounted in individual cassettes in a skeletal frame for ease of removal or replacement, and for reducing or preventing egress of the printing medium into the environment.
