Help you understand carbonless printing paper

The public special printing paper is classified according to the size and the number of layers of the paper, such as 241-1 and 241-2, which respectively represent 1 and 2 layers of narrow-line printing paper, and of course there are 3 layers and 4 layers; Commonly used wide-line printing papers are 381-1, 381-2, etc. For example: 241-2 refers to carbonless printing paper (also called pressure sensitive paper). Can only print on a stylus printer. 241 stands for: 9.5 inches, which is the width of the paper. This type of paper is also called 80-column printing paper, that is to say, the normal font has 80 characters in one line. The main uses of these papers are: outbound/inbound bills, reports, and receipts. Applicable to: banks, hospitals, etc.
Carbonless printing paper, also known as pressure sensitive printing paper, is composed of top paper (CB), middle paper (CFB) and bottom paper (CF). It uses the principle of chemical reaction between the color developing agent of the microcapsule and the acid clay in the color developing agent layer. During printing, the printing needle presses the paper surface to achieve the color development effect. The common and commonly used color layers are 2 to 6 layers.

The specifications of commonly used carbonless printing paper are 80 columns or 132 columns, as well as special specifications (width, length, horizontal equal parts, vertical equal parts, etc.). The most commonly used is 80 columns, and the size is: 9.5 inches X 11 inches (with holes on both sides, 22 holes on each side, and the distance between each hole is 0.5 inches) approximately equal to 241 mm X 279 mm. 80-column paper is usually divided into three specifications:
1: Full page (9.5 inches X 11 inches).
2: One half (9.5 inches X 11/2 inches).
3: One-third (9.5 inches X 11/3 inches).
After opening the box, pay attention to it. If it is not used for a long time, it should be put in the original packaging plastic bag to prevent moisture and damage. Color, etc., affect the use. Before using the product, confirm the position of the printer. When printing in multiple layers, try not to use high-speed printing to ensure the clarity of the printed handwriting. Note that the documents should be stored separately, if they must be stored together, avoid squeezing. It should be protected from light, water, oil, acid and alkali. As long as in the right environment, carbon-free printing paper can be preserved for at least 15 years. If there is a paper jam during printing, check whether the position of the printing paper is appropriate, whether it is aligned with the tractor, and whether the print head has selected a position suitable for the number of layers of paper.

Receipt printer or flat push printer, etc. are most suitable for the use of multi-link carbonless printing paper products. These printers are designed so that the printing paper is not bent in the machine, the printing paper is flat, and the printing force is also greater.
