Abstract:
A method of making a hand stamp having a body portion having a surface comprising the steps of:(a) constructing a printing element having an image thereon comprising the steps of: (i) overlaying a first transparent film over a first negative having formed thereon the negative of the image to be produced; (ii) depositing on said first transparent film a photopolymer to form a precursor printing element having a first and second surface said photopolymer exhibiting visco elastic characteristics; (iii) overlaying a second transparent film over said photopolymer; (iv) superimposing over said second transparent film a second negative having at least one clear area in index with said image of said first negative and an opaque area surrounding said clear opening; (v) passing rays of light through said second negative to expose said second surface of said photopolymer to light to form a printing element engagement surface comprising a multiplicity of microscopic protuberances; and (vi) passing rays of light through said first negative to expose said first surface of said precursor printing element to light to form a printing element having an image. (b) urging said printing element engagement surface into pressural engagement with the smooth surface of said body portion of the hand stamp to cause said multiplicity of microscopic protuberances to grip said surface of said body portion of the hand stamp.
