NCR is literally no carbon paper, this paper not only saves resources but also very environmentally friendly, can use repeatedly on the line. Coloring wax carbon paper NCR is not required. Multi-page NCR when stacked together, you can print directly or pen to write out a multi-copy documents. Not only convenient, clean, can also be made perforation style blank computer printing paper, continuous printing for efficient replication.
NCR reason can not replicate it waxed carbon paper, coated with chemicals because of the reason.
Carbonless paper is structured into the sheet, the sheet and the next sheet of paper. In the next face of the sheet and the sheet is coated with a drug, and the next sheet of paper on the side of the sheet, coated with other chemicals. When in accordance with the page, the page (or can not until 6), the sequential composition of the next page, by the impact of the print tip of the needle or the pressure will encounter two different drugs which were excellent tracks, in order to achieve replication the purpose. These are described in the basics of carbonless paper.
CB on sheets of paper used to call only at its next surface coated with a drug known as CB CB surface; habit called CF under sheets of paper, carbonless paper, only one side of the ingredients are coated with drugs on it and CF called CF surface; habit called in CFB sheets of paper, on which side of the CF face painted next to CB topcoat surface.
CB is a drug capsules containing paint binders and additives. Capsule diameter of only 3 ~ 7цm, shell made from resin, solvent oil inside the package, colorless oil containing dye. When the capsule is damaged by an external force, the oil will flow out of the dye, when the CB is attached to the surface of the CF surface, the dye surface so that the oil will flow CF CF significantly superior to drugs.
CF color-developing agent containing the drug, a binder, coating additives, color developing agent and certain resins mainly attapulgite.
These presentations by the above, it is clear NCR can see it is not possible to constitute harm to human body, we can not have so many scruples.
