Carbon paper is a paper coated with an acid developer on the front side and a microcapsule containing a colorless leuco dye on the back. When the paper is overlapped, the microcapsules are broken due to mechanical pressure, and the colorless leuco dye overflows with acid and develops color. Form an image. This paper can be used in multiple sheets and used as a ticket.

Carbonless copy paper
Carbon Paper - Thermally sensitive paper has temperature-sensitive chemicals that turn black after high temperatures.
When the tip of the pen passes, the friction instantly generates a high temperature, which makes the place where the handwriting passes darkens.
Bake directly with a lighter and you will notice an instant discoloration on the paper.
Not suitable for archival preservation.
Carbon paper - pressure sensitive paper (a) pressure sensitive paper is applied to its surface
The paper that creates the text or pattern by the pressure of the carbon paper at the top of the paper will produce marks when subjected to a certain external force on the upper and lower layers. It is generally used to print various bills, bills, and the like.
(2) A paper produced by coating a pressure sensitive coating on one or both sides of a base paper. Strong bonding.
High bond strength and light resistance. The product is usually cut into narrow rolls. Pressure sensitive coating formulations should be considered to prevent hardening of the pressure sensitive adhesive during storage. The base paper usually uses unbleached or semi-bleached kraft pulp and has good affinity with the pressure sensitive coating to obtain a uniform coating surface. The smoothness, tensile strength and tear of the base paper are both high. The product can be used for the sealing of the box, as well as for the production of various types of advertising paper sheets and labels.
Blue paper
There is a blue dye on the back of the paper, which is printed on the next page under pressure.
Carbonless copy paper
There is no need to use carbonized carbon paper. When multiple pages of carbonless copy paper are stacked together, multiple copies of the document can be copied by direct printing or pen writing. It is not only convenient and clean, but also can be made into perforated blank computer printing paper for efficient and continuous printing and overwriting. The reason why carbonless copy paper can be rewritten without waxing carbon paper is because of the chemical application. Carbonless copy paper is divided into upper page, middle page and lower page. On the next side of the upper and middle pages, a certain medicine is applied, and on the upper side of the middle and lower sheets, another chemical is applied. According to the order of the upper page, the middle page (can be used or not until 6 pages) and the next page, when the impact force of the printing needle or the pressure of the pen tip is received, the two different medicines will meet and become excellent, thus achieving the rewriting. purpose. The upper page is used to be called CB paper. It is coated with CB medicine only on the next side and is called CB surface. The next sheet of paper is called CF paper. It is only coated with CF medicine on one side and called CF surface. The page paper is used to be called CFB paper, and one side is coated with a CF surface and the lower side is coated with a CB surface.
Carbonless copy paper product classification:
1. Carbonless copy paper is divided into five types: upper paper (cb), middle paper (cfb), lower page (cf), single-function self-inductive paper (sc) and dual-function self-inductive paper (scb).
2. Carbonless copy paper is divided into blue printing paper, black printing paper or other color printing paper according to different color development.
3. Carbonless copy paper is divided into five types according to color: red, yellow, blue, green and white.
4. Carbonless copy paper is divided into first, second and third grades according to different quality.
5, carbonless copy paper according to light resistance is divided into ordinary type and light resistant type.
Carbonless copy paper specifications: one, two, three, four
What are the sizes of ordinary carbonless copy paper:
Large 16 open 21 × 28.5cm positive 16 open 19 × 26cm
Large 32 open 14.5 × 21cm positive 32 open 13 × 19cm
Big 48 open 10.5×19cm positive 48 open 9.5×17.5cm
Big 64 open 10.5×14.5cm positive 64 open 9.5×13cm
Colored paper non-carbonless copy printing:
16 open positive 19×26cm
32 openness 13×19cm
48 open positive 9.5 × 17.5cm
48 open positive 9.5 × 17.5cm
The above is the introduction of the principle of carbon paper and the size of the carbon paper, I hope to help everyone.
