ABSTRACT:
A composite stamp pad for coating a stamping device with ink. The composite stamp pad is composed of a porous ink pad with a porous reservoir liner. The porous reservoir absorbs any ink which may leak from the pad due to heat or high humidity. Ink absorbed into the reservoir flows back into the pad automatically when temperature or humidity return to moderate levels. The reservoir and ink pad each have an open cell structure wherein the average pore diameter of reservoir is at least about 10 micrometers greater than the average pore diameter of the pad.
