Flexographic printing using a processor to apply a control value to an ink pumping and control system responsive to the control value, where the control value sets an operating mode of the ink pumping and control system, where the ink pumping and control system includes a stepper motor coupled to a peristaltic pump. Ink is pumped through the rotary coupling into a rotating diffusion cylinder and metered through a plurality of passages so as to contact a permeable membrane covering the diffusion cylinder. A dual blade assembly cleans the permeable membrane and ink passing through the permeable membrane is metered onto a printing plate or printing sleeve.
