But they also cost more, she says. According to Schenck, they are better suited for high-risk accounts and official documents, such as birth and death certificates, stocks and bonds, licenses, titles and diplomas.

Some security features require the recipient of the document be trained to look for them. If heat reactive ink is used, recipients must hold the document between their thumb and forefinger to verify. The ink changes color due to body heat. If fluorescent ink is used, the recipient needs an external device such as a black light to detect the printing. The application dictates whether or not these features should be used.
