Abstract:
1. A process for identifying a color shift on a length of textile material wherein the color shift is associated with a predetermined threshold value, comprising: acquiring a plurality of color measure data points from the length of textile material wherein a change in color applied to the textile material occurs at some location on the textile material; associating each color measure data point with a location on the textile material from which the color measure data point was acquired; calculating an average of the acquired plurality of color measure data points; computing a color difference measure for each color measure data point by incrementally comparing the respective color measure data point to the calculated average; and comparing the color difference measure to the predetermined threshold value, wherein the first color measure data point to have a color difference measure of equal to or less than the predetermined threshold value is identified as the approximate location of the color shift.
