In the art of printmaking, AP refers to a process in which an artist tries to print prints, which is also called "artist proofing" or "artist seal". AP is not included in the count of limited edition paintings, and usually has higher artistic value because it is part of the creative process.

Is there a difference between AP in printmaking and ordinary printmaking?

Artist-certified prints usually have different characteristics from ordinary prints. The artist may adjust the color or paper quality and make several adjustments before the final work is completed. Parts, colors or printing process of AP works can be different from limited edition prints. Artist certificates are generally signed and numbered by artists themselves, which are generally less than limited editions.

What is the value of AP printing in the traditional market?

AP prints are very important for artists and art collectors. They not only improve the value of artistic works, but also provide a way to explore the creative process of artists. Some collectors even prefer to collect artists' certificates rather than ordinary prints, because they are figures in the creative process and created by artists themselves. Dynamic, interesting and personalized AP prints are also favored by collectors.
