Carbonless copy paper, non-carbon copy paper, or NCR paper is an alternative to carbon paper, used to make a copy of an original, handwritten (or mechanically typed) document without the use of any electronics. When someone writes on the sheets, the pressure from the point of the writing instrument causes the micro-capsules to break and spill their dye. Since the capsules are so small, the print obtained is very accurate. NCR glue is used to bind the different parts together.
