Abstract
A modified ink cup for plate printing is presented, where the ink cup is separated internally into two domains, a storage area and a print area, by a baffle system. The baffling allows only a limited amount of exposure of the ink in the ink cup to the outside air, reducing evaporation of the ink solvent and extending the life of the ink supply in the cup. This system greatly reduces the number of times an ink cup has to be re-filled to perform plate printing and limits the evaporation of possibly toxic solvents to the air.
