ABSTRACT Distortions during printing and laminating are minimized by printing the design on a stable base, prefer- ably release paper, and then transferring the printed design to a hot plastic web made continuously by an extruder. A stress relieved hot plastic film is then laminated to the printed web to provide a protective wear coat. To emboss in register with the printed design the laminated product is first aligned by means of regis- tration marks that are printed along with the design. Embossing is then made using a conventional engraved roll having raised sections which are images of the printed design. After embossing the web is partially cooled and annealed. It is then aligned with a die cutter using the same registration marks as used for alignment during embossing. As a result, individual tiles can be cut automatically in register to the printed and embossed pattern.
