Patent ID: 8145345

Claim:
The process of generating a series of unique virtual composite patterns for use in patterning a series of textile substrates, with each of said unique patterns being intended for a series of individual textile substrates so that no individual textile substrate in the series carries a pattern that is superimposable upon the pattern of any other textile substrate in the series, said process comprising: (a) forming a first and a second virtual layer, said first layer being referred to as a base layer and said second layer being referred to as an overlay layer, each of said layers being capable of storing pattern data; (b) establishing a base layer host pattern from which a series of non-repeating base layer patterns can be extracted; (c) extracting a base layer pattern from said base layer host pattern; (d) establishing a source of overlay layer patterns from which at least one overlay layer pattern can be extracted, wherein each of said extracted overlay layer patterns contain at least one visually apparent pattern element that is common to all composite patterns in said series of patterns; (e) extracting an overlay layer pattern from said overlay layer pattern source; and (f) forming a series of non-superimposable composite patterns, each comprised of a non-repeating base layer pattern and at least one overlay layer pattern containing said common pattern element.
