How did the ancients copy calligraphy and painting? Was there that technology at that time? Thank you for your answers.

The copying methods of China ancient paintings and calligraphy works include manual copying and woodcut watermarking.

Copying is Gu Shuhua's traditional method of copying. When you look at the original painting, copying means that there is a manuscript below. If you want to draw completely according to the manuscript, copying is a combination of the two, and the least difference from the original is copying. The job requirements are extremely delicate and complicated, and it must be meticulous, which is a severe test for the physical strength and vision of copywriting.

Brief introduction of manual copying technology;

Yellow wax method: tissue paper, coated with yellow wax, ironed with an iron to become transparent. Also known as hard yellow. Use double hook and double filling method. It is not easy to faint. However, hard yellow can be used as the medium, and then other rice paper can be used for transfer.

Manual copying process: painting box, light box (light source is sunlight), and two wooden pipes on both sides can hold scrolls. Ancient paintings are not allowed to be drawn directly on paper. So I invented the picture frame.

Gu Shuhua Copying and Copying Techniques Woodcut Watermarking Steps: Sketch, Manual Color Separation, Painting on Swallow Paper. Engraving: Swallow hide paper, very thin, stuck on the board. Printing, powder spraying and coloring. The change of depth is realized by the strength of grasping the rake.
