ABSTRACT:
This invention relates to a method of creating a seamless printing master for use with an embossing roll to ultimately produce a textured wall or floor covering. A hardenable material is applied to the textured surface of a positive printing master. The embossing roll is placed on the positive printing master and then rolled in a forward direction, compressing the hardenable material between the textured surface of the substrate and the outer surface of the embossing roll, until approximately three fourths of the circumference of the embossing roll is covered. The hardenable material is then allowed to harden. A second amount of hardenable material is applied to the portion of the positive printing master which corresponds to the uncovered portion of the embossing roll. The positive printing master section is rotated in the forward direction once again and the second amount of hardenable material is uniformly compressed between the textured surface of the substrate and the remaining uncovered portion of the embossing roll. The second amount of hardenable material is allowed to cure to a hardened state. The positive printing master is then completely removed to exposing a seamless negative printing master formed in hardened material and firmly affixed to the embossing roll. The prepared embossing roll can then be used in a conventional embossing process to create a textured wall or floor covering.
