1. No Carbon Required Paper
One side of the paper is coated with microcapsules (CB), the capsule contains pigment, and the Other side is coated with a color developer (CF side). When used, the CB side should correspond to the CF side. When the paper is pressed, the microcapsules on the CB side break , The pigment escapes and reacts with the color developer on the CF surface to develop color, and this principle is used to achieve the replication effect. Generally, NCR can be divided into three types: upper paper, middle paper, and lower paper, which can be prepared according to the number of copies required.
2. Thermal paper
The surface of the paper is coated with a paint containing a color material. This color material develops a color through a chemical reaction when heated. A mobile hot head can be used to develop color in the heated area. The facsimile machine uses this principle with thermal paper to achieve The power of faxing.
3. Ink Jet Printing Paper
Ink is directly sprayed on the paper surface through the nozzle to show the phase. In order to achieve the characteristics of small diameter, neat edges and high density, the paper must have a fine porous structure. In the case of multi-color inkjet, in order to reduce burrs, mixing, and through-printing, the water absorption and water repellency of the paper surface must be strictly controlled.
4. Photocopy paper (Plain Paper Copy, ppc for short)
In order to make the photocopying work smooth, the paper used in the copier must have the characteristics of stable size, antistatic, and carbon ink.
5. Even (Heavy) Nitrogen Sensitive Paper (Diazo Paper)
The positive film made by coating the base paper with even (heavy) nitrogen photosensitive solution. In order to make the photosensitive effect even and fine, the coated base paper must be evenly woven, free of impurities, low pH, high sizing degree, and even and fine on the paper surface.
6. Electrostatic Recording Paper
The paper surface is coated with conductive layer and insulating layer paint, and can accept the voltage discharged from the needle electrode to destroy the insulation on the paper surface and form an electrostatic latent image with the conductive layer, so that when the developer is added, it can adhere to the pattern, and then The hot melt fixes on the paper to produce a clear pattern.
7. Optical Character & Mark Reader Paper
Paper used for printing on optical readers for reading text. Numbers are called QCR and those with special marks are called OMR. Because they use optical absorption or reflection to read. To avoid misreading, the paper is clean and smooth. It has high requirements for resistance, abrasion resistance, dimensional stability and electrification prevention.
8. Magnetic recording paper (Magentic Ink Character Reading paper, MICR paper)
The surface of the paper is coated with strong magnetic particulate powder, and the paper that can be printed by the computer can be recognized by the magnetic ink. It is mainly used for ticket coupons, such as securities, tickets, and passes.
