NCR papers are a type of self-copying paper that perform the copying function without the need for traditional carbon sheets. These papers consist of multiple layers (typically 2 to 5), each coated with a specific chemical. When pressure is applied to the top sheet—such as through writing with a pen or using a printer—a chemical reaction between the layers transfers the text or image to the sheets below.
