Bank check paper is a special kind of paper specifically made for the purpose of printing checks. A bank check is a secure medium of payment, in the form of a written order. A bank check is a Magnetic Ink Character Recognition technology or MICR-encoded document, and the paper used for printing checks is known as "safety paper." This safety paper, also known as check paper, is a chemically treated bonded paper and is primarily used for printing bank checks, coupons, deposit slips, merchandise certificates, negotiable bonds, and warranties.

Generally, check paper is durable and can withstand mechanical stress exerted by high-speed equipment. The primary feature of safety paper is that it helps detect forgery and alterations. Original document security screens and authentic watermarks are the other features of check papers. Check paper also has the ability to hold various security inks employed in check printing, and it is capable of imprinting sharp, unbroken MICR characters and pictorial representations. Check paper comes with a protective background and is available in a range of colors and designs.

There are certain basic requirements to print high-quality checks, the most important of which is the quality of the bank check paper. Check paper must have a moisture content of 4% to 6%. For best results, bank check paper must be stored in an area free from extreme temperatures and humidity. In addition, good bank check paper possesses safety features such as microline, void pantographs, and a warning band to detect fraud checks.

A bank check paper should conform to the standards prescribed by the Federal Reserve Board of Governors CC. Since it maintains a high level of security and reduces the probability of fraud, MICR is employed to scan and process bank check papers.
