How does single sided carbon paper work, what is the principle of carbon paper

Hello, there are two kinds of carbon paper: one is thermal paper; There is also a carbonless carbon paper.

The principle of thermal paper is: there are temperature-sensitive chemicals on the paper surface, which will turn black after high temperature, and when the tip of the pen is crossed, the friction force is instantaneous.

High temperature, is the note walked in the place blackened, directly with a lighter, you will find that the paper instantly discolored, than as an archive preservation.

The principle of carbonless carbon paper is: it is composed of two sheets of coated paper in contact with each other, and the main components are base paper, hair color coating, and color coating.

Layer. Its working principle is that under the action of pressure, the chromogenic coating and the chromogenic coating carry out a chemical reaction to synthesize a colored substance on the paper and develop color.

The principle of carbon paper, for example, is like the footprints of a foot.

The principle of carbonless carbon paper is to apply a dye capsule on the back of the upper layer of paper, and apply acid powder on the lower layer of paper, and the capsule is scratched under the action of external force, and the acid powder is contaminated to the bottom to produce handwriting. Ordinary carbon paper is coated with dark ink on both sides, sandwiched between two sheets of white paper, and the color can be copied onto the paper below under the action of external force.

Modern carbonless copy paper is the back of the upper carbon paper is coated with a dye capsule, under the action of external force, the capsule breaks, stained with the acidic powder of the upper and lower carbon paper, the two react, produce dark blue handwriting, more advanced and do not need to use the ink full of the copy layer.

Ordinary carbon paper is to coat the paper with dark ink, sandwich it between two sheets of paper, and the handwriting cuts the ink copy paper through the white paper above, and the ink imprint is printed on the paper below. The advantage of ordinary carbon paper is that it can be used over and over again.

At present, the carbon paper commonly used is carbonless carbon paper, which is more convenient to use, can be directly colored, and is mostly used for bills, express delivery sheets, etc. The advantage is that the copy is legible, does not fade, and does not contaminate stationery and other paper, keeping it clean and tidy.

1. When copying, there is no pad "blue paper", which is convenient and time-saving for direct writing, and the number of copies is 2 6 pages, and the electric printing is 2 10 pages, which can greatly improve work efficiency and meet the needs of modernization. It is more suitable for telegraph and computer list machine for multiple copies.

2. The handwriting of the copy is clear and distinct, and does not fade, which can prevent alteration and imitation.

3. Do not pollute fingers, clothing and other stationery paper, and keep it clean and clean.

4. It has various colors and is easy to identify and process.

5. The paper is excellent, the surface is smooth and smooth, the printing processing is easy, and the printing color is gorgeous.

6. It does not contain harmful raw materials and peculiar smells, is safe and reliable, and can be stored for more than 15 years after color development.

A kind of paper coated with an acidic chromogenic agent on the front side and a microcapsule containing a colorless cryptodye on the back, when the paper is overlapped, the microcapsule ruptures due to mechanical pressure, and the colorless cryptochrome overflows when it encounters acid and forms an image. This paper can be used as multiple overlapping sheets and is mostly used as a bill.

Carbon paper is a kind of paper coated with an acidic chromogenic agent on the front and a microcapsule containing a colorless cryptodye on the back. This paper can be used as multiple overlapping sheets and is mostly used as a bill.

The carbon paper is the one on which the upper layer of paper is covered with countless dye capsules on the back; On the front of the lower layer of paper, apply an acidic powder. When we run the tip of the pen across the front of the top paper, the capsule on the back will be crushed, releasing the dye. When the dye encounters the acidic powder on the front of the lower layer, it produces a deep blue color.

Carbon paper is a type of paper with a shiny front.
