Abstract
Continuous or endless loop printing ribbon cassettes and reinking devices therefor which will control the start of reinking transfer flow and the reinking transfer flow rate from the reinking device to the continuous or endless loop printing ribbon fabric substrate. One preferred embodiment of the reinking device in accordance with the present invention utilizes two cylindrical ink rolls positioned concentric to each other. The inner ink roll is saturated with an ink having a normal flow rate and acts as a reservoir. The outer ink roll is saturated with an ink having a higher viscosity or other materials which delay the start of reinking transfer flow when the continuous or endless printing ribbon cassette is new and controls the ink transfer flow rate during the useful life of the continuous or endless loop printing ribbon cassette. In a second preferred embodiment, the inner ink roll is replaced by an inner ink reservoir which controls the ink transfer flow rate to the porous outer ink roll.
