Eight special paper performance application tips

noncarbon required paper: one side of the paper is coated with microcapsules (CB side), which contain pigments, and the other side is coated with chromogenic agent (CF side). When used, due to the recent recession in the laboratory machine industry, the CB side must correspond to the CF side. When the paper is under pressure, the microcapsules on the CB side break, the pigments escape and react with the chromogenic agent on the CF side to produce color, Use this principle to achieve replication effect. Generally, NCR with prosperous market can be divided into upper paper, medium paper and lower paper, which can be deployed according to the number of copies required

thermal paper: the surface of the paper is coated with a coating containing pigment, which is heated to produce a chemical reaction to develop color. A mobile heat head can be used to develop color in the heating area. The fax machine uses this principle and matches with the heat sensitive paper to achieve the function of fax phase display

Inkjet printing paper: ink is sprayed directly on the paper surface through the nozzle to show its appearance. In order to achieve the characteristics of small diameter, neat edges and high density, the paper must have a fine porous structure. In multi-color inkjet, in order to reduce burr, mixing and through printing, we must carefully control the water absorption and water repellency of the paper surface

plain paper copy (PPC for short): in order to make the photocopying operation smooth, the paper used by the copier needs to have the characteristics of stable size, antistatic, and good carbon ink fixation

diazo paper: a positive photosensitive paper made by coating the base paper with muon (diazo) photosensitive liquid. In order to have a uniform and fine photosensitive effect, the coated base paper must be evenly interwoven, free of impurities, low pH, high gelatinization and uniform and fine paper surface

electrostatic recording paper: the paper surface is coated with conductive layer and insulating layer paint, which can accept the voltage released from the needle electrode to damage the insulating layer on the paper surface and form an electrostatic latent image with the conductive layer, so that the developer can adhere to the pattern when added, and then heat melt and fix it on the paper to produce a clear pattern

optical character mark reader paper: it is a kind of printing paper used in optical readers. It is used to read words. The number of digital ones is called QCR. Reading is special. In recent years, the number of plastic machines imported into China is also rapidly promoting. The marker is called OMR, because it uses optical absorption or reflection to read. In order to avoid misreading, the cleanliness, smoothness and wear resistance of the paper, not to mention how to maintain the rub High requirements for dimensional stability and electrification prevention

magnetic ink character reading paper (MICR paper): the surface of the paper is coated with strong magnetic particle powder, and the paper can be printed with magnetic ink, which can be recognized by the computer. It is mainly used for valuable tickets, such as securities, train tickets, passes, etc
