ABSTRACT:
A method for producing intaglio designs in cast acrylic material, wherein a moulding tool hotter than 600.degree. C. is applied to a surface contact area of an acrylic surface in which the intaglio copy of the moulding tool is to be formed, and the moulding tool is withdrawn from the surface contact area before the temperature of the tool or the acrylic material of said area falls below that at which methyl methacrylate vapor ceases to be produced by the depolymerization of the acrylic material. The preferred withdrawal temperature is above 250.degree. C.
