Distortions during printing and laminating are minimized by printing the design on a stable base, preferably 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 registration 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.
A method of making, on a continuous basis, a composite vinyl tile comprising the steps of:
