Carbonless paper features a convenient two-ply design which produces both a yellow and a white copy. This results in both a copy for you and a copy for the customer. It works by using a traditional register printer with a standard register ribbon. The ribbon prints onto the first copy and the pressure from the printing transfers a copy onto the second sheet for a duplicate print.
