Abstract
A yarn color placement system for a tufting machine including a series of different color yarns being fed to the needles of the tufting machine by yarn feed mechanisms. A backing material is fed through the tufting machine at an increased stitch rate as the needles are shifted according to the programmed pattern steps. A series of level cut loop loopers or hooks engage and pick loops of yarns from the needles, with the clips of the level cut loop loopers or hooks being selectively actuated to form cut pile tufts, while the remaining loops of yarns can be back-robbed so as to be hidden from view in the finished patterned tufted article.
