Copying table is also called writing table, light-transmitting table, calligraphy copying table and movie reading table. In fact, the principle of the copy desk is very simple after all. Use light transmission on the back of the drawing paper, then copy the main contents of the previous one, and draw the next decomposition action on the new paper, so that the light transmission equipment at the back is very important.
Most of the early copying tables were inlaid with a piece of glass on the wooden desktop, with candles and oil lamps as the main light sources below. Later, someone changed the light source into an incandescent lamp, which was the prototype of the early copying table. The traditional light transmission equipment is made of wood, and the lamp is put in it.
Now the development of technology can give us a thin LED light board, which can be connected to the USB power supply of the computer and started to work. In the early days, it was a professional tool for making cartoons and animations, but now it is mostly used in the field of hand-drawing, cleaning up design and illustration lines. The brightness of LED lamp can be adjusted. When an animator uses it, he can stack several drawings together, so that he can clearly see the picture on the bottom drawing and copy or modify it on the first paper.
Animators can use decomposition action (Chinese painting) to draw action. They can stack 7 or 8 sheets of paper and draw 7 or 8 exploded drawings in a row. It is also easy for cartoonists to describe the draft as a formal draft, so the copying table is also one of the necessary tools for professional cartoonists.
For ordinary people, of course, copying calligraphy and painting. For example, copying complex paintings for other purposes, many beginners of painting start from copying, and learning with copying desk is twice the result with half the effort.
