Carbonless Paper Roll The Technical Requirements
Carbonless Paper Roll The technical requirements
Under the guidance of high-tech, now the web printing market is the best state of rapid development. Especially from the mail delivery, securities, insurance, banking, commercial computer-free carbon copy notes, as well as airport tickets have a special anti-counterfeiting technology requirements. The following focus on non-carbon paper printing and the technical requirements.
First, the requirements for non-carbon paper
Carbon-free rewritable notes require a special paper, a coated paper, also known as CCP paper. Usually it is divided into paper (CB), medium paper (CFB), under the paper (CF) 3 kinds. Carbonless paper is a special paper that prints two or more computer bills and ordinary notes. (CB) refers to the paper for the first joint of the various bills, coated with a layer of microcapsules on its back, which plays the role of transferring text downward; and medium (CFB) For the various re-writing notes in the special-purpose paper, its front coated with a layer of color reagent, the back of the same paper coated with a layer of microcapsules, served as a joint transfer at the same time the role of the next; The final combination of the various rewritten notes is applied only to the surface of the paper with a layer of developer, which serves to carry the contents of the copy. In the case of printing carbon-free rewritable notes, if it is a computer-specific paper, it must be carbon-coated with a reel, and there is a more stringent process requirement for the toughness, thickness of the web, the elasticity of the rolls, and the number of joints.
Second, the bill printing production scheduling process arrangements
When receiving a production task, the production dispatcher according to the process of single content, the number of colors, the number of paper and paper and other materials used to design a series of the best process, especially multi-color bill The printing should be arranged in advance of the printing order or color order.
Third, the printing process points
Print stress is accurate overprint. No matter what kind of printed prints should be printed on the accuracy, in particular, printing multi-computer dedicated carbon-free replication notes, the more stringent requirements. Computer-specific notes need to be perforated printing, folding, etc. to suit the computer. Whether it is printed single row of holes or double row of holes, according to the requirements of the computer to achieve the following:
(1) with high-precision punching, punch to penetrate the hole. Otherwise it will produce a computer card machine or print errors and other undesirable phenomena.
