Abstract: A bonded microporous synthetic rubber, used in the manufacturing of pre-inked stamps and more specifically in the manufacturing of flash preink stamps, is disclosed. The bonded microporous synthetic rubber is made by gluing synthetic rubber with a polypropylene foam using synthetic glue. A tracing sheet containing the image of the desired text of the stamp is placed on the microporous synthetic rubber and it is exposed in a flash stamp system (with Xenon tubes) which delivers an intense burst of light that seals the non- printing area, thereby producing an image of precise resolution. After producing the image, the bonded microporous synthetic rubber is glued to a refillable stamp mount/pocket stamp mount. The refillable stamp mount includes an inking tube through which flash ink is poured. The bonded microporous synthetic rubber has good ink absorption and retention and thus in turn supports a greater number of impressions per inking.
