Abstract

Pre-inked impression members for hand stamps are made from a gel or premix of thermoplastic resin particles and liquid ink with use of a disposable molding device comprising a matrix board that is recessed in its molding area with cavities to form inked indicia of the impression members and has a peripheral surface area to which is adhered fluid-tight, and entirely about the molding area, an upright rigid wall means comprising a structure of fiberboard, wood, hard resin or other suitable material shaped to a height corresponding to the desired thickness of the impression members. As another feature, during the heating for curing of a layer of premix formed over the molding area of a matrix board, the layer of premix is confined in place by a covering means, applied over it and held under pressure, which comprises, together preferably with overlaid pliable ink-absorbent material, e.g., plural cut sheets of newspaper, a pliable parting sheet, such for example as a sheet of emery cloth, coated on a side thereof contacting the layer of premix with a substantially resin-impermeable yet ink-permeable layer of fine particles nonadherent to the resin of said premix.
