Provided herein is a process for randomly patterning a plurality of carpet tiles, each tile having a composite pattern containing at least a base pattern and an overlay pattern. When installed, the random order of patterning results in random tile placement and an overall random appearance. The overlay patterns are randomly chosen from a library of patterns until each individual pattern has been used to create a tile series. The overlay patterns may be manipulated by rotating, mirror-imaging, rotating and mirror-imaging, or repositioning to produce additional variations and increase the number of tiles in the series. The base pattern may optionally be manipulated before being incorporated into the composite pattern. A tile collection, containing such randomly ordered composite patterns, is also described. 1. A series of carpet tiles in which each carpet tile carries a composite pattern comprising at least an underlying pattern that is common from tile to tile and an overlay pattern that is randomly selected from a predetermined library of such overlay patterns , wherein each overlay pattern is selected as part of a composite pattern to form a complete series.2. The series of claim 1 , wherein said overlay pattern is electronically manipulated prior to the formation of said composite pattern.3. The series of claim 2 , wherein said overlay pattern is subjected to electronic manipulation using at least one technique selected from the group consisting of rotating claim 2 , mirror-imaging claim 2 , rotating and mirror-imaging claim 2 , and repositioning.4. The series of claim 1 , wherein a single overlay pattern and a single underlying pattern are used to form said composite pattern. This application is a divisional of U.S. patent application Ser. No. 13/433,385, entitled “Automated Randomized Pattern Generation Using Pre-Defined Design Overlays and Products Produced Thereby,” which was filed on Mar. 29, 2012, which is a divisional of U.S. Pat. No. 8,155,776, which was ...
