Specifications are generally divided into two kinds of flat and reel. Flat paper is mainly used by one use, such as printing presses and writing for the platform and painting paper. Web processing machinery mainly for continuity of use, such as for rotary printing machine, bag making machine continuous non-carbon paper bag manufacturing company documents, cigarette packs of cigarettes and other machine continuously. For printing paper and the magnitude of the general requirements to match the printer series. Roll width 787 and 1092mm past, and its multiples based, with the changing web printing press, is phased to 880mm with its multiples based. Roll outer diameter is generally 750 ~ 850mm. Flat paper aspect ratio of 0.72. Customary to 500 as an order, several reams of paper packaged into a high-grade non-carbon paper documents, each weighing no more than 250kg. Other paper due to a variety of special requirements of different non-carbon paper documents, will have different specifications, or special production specifications required by the subscriber. Hair color principle on paper, the paper is coated with a back coating paint CB, CB coating main material is a microcapsule, capsules containing Diphenylethylane as carrier crystal violet lactone (referred to as CVL). In front coating paper and lower paper coated with paint CF, CF coatings is mainly composed of phenolic resin or zinc species, or phenolic resin and zinc salicylate graft copolymer produced. When there are different materials of paper Dangtu contact with each other, and the color reaction does not occur only when printing or writing, microcapsules by external force, cyst rupture, Diphenylethane bag to contain the flow of CVL color coated with a resin coating, the chromogenic material and the color developing substance will react color, resulting in writing.
