How to use carbon paper Copying ancient poems is exhausting. I don t know how to use it

Put carbon paper between the two sheets of A and B that need to be written, and write text on A to copy to B.

Principle of carbon paper: carbon paper is a kind of carbon paper coated with an acidic chromogenic agent on the front and a colorless cryptochrome on the back.

When the paper is overlapped, the microcapsule is ruptured due to mechanical pressure, and the colorless cryptochrome overflows and encounters acid to form an image. This paper can be used as multiple overlapping sheets and is mostly used as a bill.

Carbon paper is placed between the sheets of paper to be transcribed, and the transcribed content is printed on the paper underneath the carbon paper.

Note: The ballpoint pen effect is better, if you want to copy clearly, you need to have a certain amount of strength in transcribing.

Disadvantages: The back of the paper is not usable - because it is stained by the ink of the copy.

Cover a piece of carbon paper on a piece of paper, cover it with another piece of paper on carbon paper and write.

Children are lazy, as soon as you copy the carbon paper, you can see that no matter what pen you use to copy the words are the same color, and they are seen through at once.
