How to transmit the words written by carbon pen to Yin Shi?

The transmission process needs to be realized through an intermediate medium.

The characters written by carbon pen are directly formed on paper, and the paper surface has a certain adsorption effect on pen and ink, which is not suitable for hard material Yin Shi. Therefore, in order to transmit the words written by carbon pen to Yin Shi, we must use intermediate media.

Generally speaking, this intermediate medium is film paper or transfer film (also called film basement membrane), which can transfer the words written by carbon pen to Yin Shi with certain adhesion.
