Abstract
The sheet is worked in order to display the relevant motifs on it, said sheet consisting of a transparent resin on which the motifs are engraved, which will produce the optical effects. It is characteristic that the hot resin, in the fluid state or forming a film, is supplied to a cooled metallic calender (rolling press) composed of a cylinder and of a surrounding mould plate (matrix board) engraved with the motifs to be transferred to the resin which is polymerized by the cold of the calender, the supply of the resin to the calender coinciding next to the point of actuation of a presser roller applied against the calender and which is also cooled. The resin which is engraved and polymerized exits the calender guided by a roller applied against it and which is also cooled.
