The three printing techniques in ancient China include batik, tie-dyeing and cutting.

1, Batik: Batik is an ancient printing process, also called wax valerian. It is made by laying a piece of white cloth flat on the table, then adding wax into a small pot, heating it to dissolve it into juice, then dipping it in wax juice with a wax knife and coating it on the cloth. After painting, put it in a dye vat for dyeing, and then boil it with clear water. After the wax melts, you can see white patterns. Batik has rich patterns, elegant colors and unique styles. It is often used to make clothes and various practical articles for life. It is simple and elegant, fresh and pleasing to the eye, and full of national characteristics.

2. Tie-dyeing: Tie-dyeing, also known as tie-dyeing, is a printing technique in which a part of the cloth is tied tightly and then dyed, so that the tied part of the cloth keeps its original color and the part that is not tied tightly is dyed.

3. Javelin (hollow printing): Javelin, also known as hollow printing, is a printing technology that engraves patterns on cloth and then fills the patterns with dyes to dye the cloth.
