<p>A method of controlling the ink feed to a printed substrate in a lithographic printing press is provided which includes providing, for each of a plurality of ink zones (a1-an), an ink coverage requirement for a printing unit (100-103) of the lithographic printing press; color scanning a first ink zone of a plurality of ink zones (a1-an) on a printed substrate (1) as it exits the printing unit (100-103) of the lithographic printing press; calculating, for each one of the plurality of ink zones (a1-an), a static initial flow change for said each one of the plurality of ink zones (a1-an) based on said scanning of the first ink zone of the plurality of ink zones (a1-an) and the ink coverage requirement for said each one of the plurality of ink zones (a1-an); calculating, for each one of the plurality of ink zones (a1-an), a dynamic flow change based on the static flow change for said each one of the plurality of ink zones (a1-an) and the ink coverage requirement for said each one of the plurality of ink zones (a1-an); and providing a flow setting for each one of the plurality of ink zones (a1-an) based on the dynamic flow change for said each one of the plurality of ink zones (a1-an).</p> |
