INK ROLLER RESERVOIR (Lathiya - Maskell) Abstract of the Disclosure An inking system for use with a printing device includes a hollow cylinder formed of microporous material. The cylinder is provided with a pair of end caps which seal the ends thereof, and the chamber defined within the cylinder is filled with ink of preselected viscosity. The micropores in the sintered material draw the ink to the exterior surface of the roller by capillary action, and permit air to enter the roller and replace the ink as it is used without permitting any leakage of the ink during normal usage. One embodiment provides a microporous sle- eve disposed about the sintered roller to replace the nor- mal transfer roller and permit direct inking of the indi- cia forming characters. -1-
