Abstract
A system and method for treatment of thread includes a thread printer that applies colored coatings to thread and that passes the treated thread to a fabric weaving system. A camera is positioned to capture images of the treated thread as it is woven into a fabric in the fabric weaving system. The system processes the images to determine whether the location of a selected segment of the treated thread in the fabric corresponds to an expected location in the fabric. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of a segments to automatically account for the misalignment.
