Print certificates of authenticity for free from templates available on Template.net, as well as ArtPromotivate.com. Customize these templates with information about the artist and the piece being authenticated.
Many artists prefer to make their own certificates of authenticity. When doing this, include the title of the piece, as well as the medium and materials used. Include the artist's name and the year he created the piece, the country in which the artist produced it, and whether it is the original piece or a print. If it is one in a series of prints, supply a print number for each piece. Include a thumbnail image of the artwork and the piece's dimensions. If there are any care instructions for the piece, explain them in detail. The artist should sign the certificate and include contact information, such as an email address or professional website, alongside a statement declaring his right to retain the copyright of the work.
If an artist decides against a template, he should use a word processing or graphic design program to create his certificate of authenticity. Many office supply stores sell pre-printed certificates. An alternative to a certificate is a small sticker on the back of the painting, which ensures that the certification will not be lost or misplaced.
