Carbonless Paper Roll Generally To Be Carried Out

Carbonless Paper Roll Generally to be carried out

Non-carbon paper printing environment control is the most important air humidity and temperature control. Paper is made of plant fiber, the porosity of the paper, the moisture absorption of the fiber and the presence of water in the fiber, etc., easily lead to changes in paper size, in the printing can easily lead to overprint is not allowed, Serious wrinkles caused by printing.

In general, carbonaceous paper paper moisture content between 6% to 8%, this water is a mechanical combination of water, commonly known as moisture absorption. There is a certain relationship between the moisture and humidity of the moisture and the air. Experiments show that under certain relative humidity, the moisture content of the paper is inversely proportional to the temperature, the temperature of each change 5 ℃, the average change in water content of 0.15%; at a certain temperature, the paper moisture content and the relative humidity is proportional to the relative humidity Each change of 10%, the average change in water content of 1%. Under normal circumstances, the water content of each change of 1%, longitudinal deformation of 0.025% to 0.05%, lateral deformation of about 1%. However, carbonless copy paper generally to 3 to 6 rewritten, sometimes the amount of the column is only 1.5mm wide grid wide, if the expansion is too large, it means that 1 yuan may be 100 yuan, so to ensure that carbon-free copy paper smaller deformation telescopic Quantity, it must be strict on the use of the environment. 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 paper (CF) 3 kinds. Carbonless copy paper is a special paper for printing two or more computer bills and ordinary notes. (CB) refers to the paper used for the first joint of the various bills, coated with a layer of microcapsules on its back, serving as a downward transfer of text; and medium (CFB) For the various rewritten notes in the special-purpose paper, its front coated with a layer of color reagent, the back with 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, 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 of the best process, especially multi-color bill Of the printing should be arranged in advance of the printing order or color order.
