When you try to scan a thick booklet or a book you can often get the above ugly crease around the staples when you try to lay the booklet flat. Less than desirable, the question is how to remove the crease mark.
While you can remove the crease after scanning this may not work so well if there is artwork close to the crease and it does add extra time and effort to the exercise, much better to scan it without the ugly crease in the first place.
