Abstract
A printing compound and methods of producing 3-dimensional signs and lettering and tactile and Braille reading materials is disclosed. The printing compound includes an ultraviolet radiation curable resin and a filler mixed with the resin to form a paste. The resin can be an acrylated urethane oligomer or an epoxidized oil. The compound is applied to a substrate manually or by a computer controlled dispensing apparatus. The compound is subjected to ultraviolet radiation to cure quickly allowing for mass production.
Claims10
A method of making three dimensional signs comprising:
- providing a substrate, applying an adhesive printing compound to the substrate, wherein said substrate has not been pre-treated for adhering said compound to said sign, said compound being a gel formed of ultraviolet radiation curable resin and a filler, said printing compound being arranged in a predetermined pattern;
- subjecting said printing compound to ultraviolet radiation after said pre-determined pattern has been formed, whereby said printing compound adheres to said sign after subjecting said compound to ultraviolet radiation.
A method of making three-dimensional signs as claimed in 1 and further comprising the step prior to applying the compound to the substrate of printing a pattern on the substrate, and wherein the compound is applied by forming a bead on the substrate around the periphery of the pattern.
