If all the sheets are creased on same position, the
bounded book cannot be turned over to lay flat like
this drawing.
With 3 crease modes, even thick paper can be
turned over very easily and lay flat after binding.
The illustration for V mode is as follows:
Define the first position and crease gap and the qty in one batch. The first page will be one
line as reference and following sheets will be 2 creases that goes further
successively to the reference line.
In this way the book can be folded with a square back after saddle stitched. The effect
of the above 4 parameters is illustrated in the drawings above.
