Copperplate is the name of the mainland, and Hong Kong calls it powder paper. It is one of the most widely used papers in the printing industry. The paper name is almost well known in Hong Kong. However, there are few people in the mainland because of the lack of communication between practitioners. The original English name of pink paper is art paper, which is a common name of imported products. This kind of paper was first developed by the British in the middle of the 19th century. The high-grade printing paper is made by mixing the white and fine porcelain clay into the coating and evenly brushing it on the surface of the base paper. Because the process is like a woman painting powder on her face, it is called powder paper.
In fact, art paper was translated into art paper in the 1930s in China. Because when we used this paper to print fine paintings in Europe, we used etched plates. Therefore, according to the Convention of naming by use, the art paper used for copperplate printing is called copperplate (printing) paper. In mainland China, printing and paper industry colleagues call art paper copperplate rather than powder paper.
By the way, some books and magazines do not translate copperplate paper into copper plate paper, or enameled paper. The former is mistaken for a paper like copper plate, which should be translated into four pages of paper, and the latter should be waxed paper (Taiwan called Liguang paper).
