The meaning of watermark is as follows:

1. The mark seen when exposed to light.

2. Refers to my country’s traditional method of printing paintings using woodcuts. The paint is mixed with water instead of oil, which is different from the general color printing method, so it is called "watermark". Also called "watermark woodcut".

3. Refers to the translucent logo and icon added to the picture to prevent others from stealing the picture.

Quotation and explanation: Sun Li's "The Collection of Xiulu·Dream of Painting": "When I was a child, the paintings I saw were all woodblock watermarks."

Development History

The earliest watermarks were created by paper craftsmen of the Tang Dynasty in my country at the end of the 8th century or the beginning of the 9th century. At that time, silk threads were woven into patterns on bamboo curtains. The pattern is more protruding than the curtain surface, so the fibers in the corresponding parts are thinner when the paper is made, and the light transmittance is higher. So you get the watermark effect.

In the 13th century, Italian craftsmen also woven letters, numbers or patterns on papermaking nets, leaving watermarks on the paper as trademarks. On the paper machine, a decorative tape (watermark tape) is used to press the wet paper page to form a watermark. The modified skirt can be carved into various patterns or patterns as needed.
