Carbonless copies of checks use a special paper known as?

The correct answer is NCR paper. NCR stands for "No Carbon Required," and this special type of paper is designed to produce duplicate copies of written information without the use of carbon paper. It consists of sheets that have a coating of micro-encapsulated dye on the back. When pressure is applied by writing on the top sheet, the dye is released onto the next sheet, thus creating a copy. This feature is particularly useful for creating carbonless copies of checks and other documents, ensuring that the original and its duplicate can be produced simultaneously and neatly.

NCR paper is widely used in various applications, including invoices, receipts, and forms, where multiple copies are needed without the mess and difficulty of traditional carbon copying. The unique properties of NCR paper make it an efficient choice for businesses that require clear documentation in multiple copies.

The other types of paper mentioned, such as OCR paper (commonly associated with Optical Character Recognition technology), MICR paper, which is used for checks and has magnetic ink characteristics, and DOD paper, which pertains to specific government use, are not designed for creating carbonless copies. Each of these types of paper serves distinct purposes that do not overlap with the benefits provided by NCR paper.
