The so-called original printmaking refers to the artist's use of the unique artistic language of printmaking (such as knife marks, original texture, etc.). ) conception, and personally create the original, control and participate in limited printing; In the whole process, the artist exerts his creativity, improvisation and randomness, which is an inseparable and important link in his works. After the final printed matter is signed by the artist himself and marked with a limited amount, it becomes an original work. According to international practice, the number of prints is strictly limited, and the printmaker will sign each print and indicate the number of prints or sheets. For example, 10/50 means that this version has printed 50 paintings, and this is 10. The less you print, the more precious it is. General printmakers will destroy the original works after printing a limited number of works.

Copying printmaking is a printmaking technique, which is made by printmakers to simulate the visual effect of an original (such as oil painting) in other media; Its printing is a process of copying and copying, and most artists will not personally participate in it.

Original printmaking is an important category of visual art, and it is one of the most sold paintings in developed areas such as Europe, America and Japan. In the modern international art market, printmaking and oil painting are equally important. It can even be considered that printmaking is almost the most valuable art investment category in the West. In China, the recognition of printmaking is not high and the market is not standardized enough. The main reasons are: firstly, many people in China think that prints are not original if they can be copied. Its originality has been questioned, not to mention its artistic value. Secondly, people in China often think that printmaking is very traditional and oil painting is more modern. Foreigners, on the other hand, think that printmaking is the artist's original, with unique artistic value and very modern.
