Development history

The earliest watermark was created by paper makers in the Tang Dynasty in China at the end of the 8th century or the beginning of the 9th century. At that time, silk thread was woven on the bamboo curtain. The pattern is more prominent than the curtain surface, so the fiber interweaving in the corresponding parts is finer and the light transmittance is higher when making paper. The watermark effect is obtained.

On the paper machine, the wet paper is pressed with decorative paper (watermark paper) to form a watermark. The decorative ring can be carved with various patterns or patterns as required.
