Density defines the maximum distance between zig-zag stitches. If zig-zag stitches form a bend, the distance on the inner curve is lower.
Start/End offset defines the size of the small gap at beginning and end of columns. The stitches seen on screen are just the axis of real stitches that are wider, in fact. This gap prevents the thread bulging at both ends of columns.
Pull Compensation is extension of each stitch on edge of object in order to compensate for thread pull (on elastic fabric) or sinkage (on fleece). The thread pull and sinkage causes that object is smaller (narower) than intended. Normal value for pull compensation is 1 or 2. Use higher values (3, 4 or 5) for elastic fabric or fleece. These values are displayed in tenths of milimeter (1/10 mm).
Random Broadening defines maximum random prolongation of column stitches to side. This creates ragged edges effect on lettering.
Broadening defines constant prolongation of column stitches to side. This parameter can be sed to increase width of letter bars.
Pattern defines the texture of cover stitches of the letters. Pattern effect is created with layout of needle points within rows of stitches. Therefore, length of stitches in fill is given by needle points distance in pattern. Pattern effect can be seen only on larger lettering (about 1 inch height or more, depending on width of bars).
Auto-shortening is function that shortens some stitches on inner side of bend object to prevent too high density.
