At the end of a cut, a small nib may remain on the bottom portion of the cut in the lead-in/lead-out area. Because of the lagging effect discussed previously, when the jet reaches the end of the cut, the top portion of the jet will find the path of least resistance, and effectively "jump over" a small bit of material leaving a nib. With the more sophisticated controls and software available today, this can be reduced by decelerating at the end of the cut to allow the bottom portion of the jet to catch up with the top before reaching the end of the cut. Figure 10 below shows examples of a large nib because of too much speed at the end of a cut and an example of a minimal witness mark with appropriate slow down at the end of the cut.
