Jump Stitch
A long, loose thread carried across the surface of the fabric when the machine moves from one stitched section to another without trimming.
A jump stitch is created when the machine needs to move from the end of one stitched section to the start of another without making a trim. The needle stops dropping while the head moves, and the thread is dragged across the fabric. After embroidery, jump stitches must either be trimmed by hand or covered by subsequent stitching.
Short jumps (under about 5mm) are usually left uncut because the surrounding stitching covers them or because trimming would slow production. Long jumps (over about 8mm) almost always trigger a trim command. Mid-length jumps are a judgment call by the digitizer based on whether they can be hidden under later stitching.
Excessive jump stitches are a sign of poor digitizing. A well-digitized design routes the needle path so that adjacent shapes are stitched in sequence with minimal travel between them. A poorly routed file zigzags around the design, leaving a dozen jumps that someone has to clip out by hand on every piece.
For short-run production this is annoying but manageable. For high-volume runs (hundreds of pieces), jump-stitch labor adds real cost. A skilled digitizer minimizes both jump count and total travel distance during routing, often saving the shop minutes per piece at production scale.
