METHOD OF PRODUCING A SIMULATED WATERMARK

摘要

A method of producing a simulated watermark in which intense, focused heat is momentarily applied, in the desired watermark pattern, onto a thin solid matrix of waxy material placed in contact with a sheet of uncoated paper. This results in impression of a durable translucent mark. The wax penetrates the paper without the need either for chemical action or the application of significant direct pressure, and creates regions of translucence in the paper fibers.
