Abstract
An ink dispensing device is disclosed wherein the ink releasing member comprises two layers that serve different purposes. The layer which contacts a printing font is made of a porous material that has an open pore size of less than 30 microns and a porosity of 40% to 85%. The second layer is adjacent to the contact layer and is made from an elastic foam with larger pore size, in the range of 80 microns to 1000 microns and a porosity of greater than 70%. The second layer is impregnated with ink and acts as a reservoir for the first layer, the latter serving as a metering member.
