Carbon-free paper introduction
there are positive and generous specifications, but there are differences between paper, medium paper and paper. The Paper price is different (see paper price classification). This kind of paper is not obviously different from ordinary paper in appearance, but it can be used for reproduction, producing the same effect as blue carbon paper, and will not stain fingers and clothes, making it more convenient and sanitary. Since this paper is not made of carbon material, it is named (carbonless review paper), referred to as carbon-free paper.
When using the document printed by carbon-free paper, it is usually equipped with a small piece of cardboard separated on the Kupono, so as not to overexert the writing force and cause other Kupono on the pad to be duplicated!
Carbonless copy paper carbon paper that does not need to be painted with wax, and can be reproduced without wax carbon paper, because of the chemical coating. Multiple pages, carbon-free paper stacked together, can be directly printed or written to copy multiple documents in duplicate. It is convenient and clean, and can also be made into hollow computer printing paper to realize efficient continuous printing and reproduction. The production of carbon-free paper base paper is very important.
Carbon-free paper principle
carbon-free paper is divided into Upper page, middle page and lower page. On the lower side of the upper and middle pages, some kind of medicine is coated, and on the upper side of the middle and lower pages, another kind of chemical is coated. After the top, middle and bottom pages are combined in order, when the impact force of the printing needle or the tip pressure of the pen, the two different drugs will meet and show wonderful marks so as to achieve the purpose of reproduction.
The paper on the Upper page is called CB paper, which is only coated with CB drugs and called CB surface; The paper on the lower page is called CF paper, and only coated with CF drugs and CF surface; the middle sheet is called CFB paper, and its upper side is coated with CF surface and the lower side is coated with CB surface. Carbon-free paper dyeing is very important. CB medicine is a coating containing capsules, adhesives and additives. The particle size of the capsule is only 3~7 * m, the shell is made of resin, and the internal solvent oil contains colorless dye. When the capsule is damaged by external force, the dye oil will flow out. If CB face mask is on the CF surface at this time, carbonless copy paper of the dye oil will flow to the CF surface to make the CF medicine show wonderful, CF drugs are coatings containing developer, Binder and additives. Developer is mainly some resin and activated clay.
Carbon-free paper can be divided into five colors; White/red/blue/green/yellow and other five colors can distinguish Kupono!

it is precisely because there are so many kinds of paper that carbon-free paper can achieve the effect of multi-copy. At present, the finished products of the list made by carbon-free paper I have seen are at most 7 copies: white, medium red, medium blue, medium green, medium yellow, medium red, and white, as long as the strength is large enough, each link can be copied!
