Special printing paper for office use is categorized by size and layers, such as 241-1, 241-2, representing single and double-layered narrow-line printing paper respectively. There are also 3-layer and 4-layer options; commonly used wide-line printing paper includes 381-1, 381-2, etc. For example: 241-2 refers to carbonless paper (also known as pressure-sensitive paper). It can only be printed on dot matrix printers. 241 represents 9.5 inches, which is the width of the paper; this paper is also called 80-column printing paper, meaning that with normal font, there are 80 characters per line. The main Applications of these papers are: in/out inventory slips, reports, receipts. Suitable for: banks, hospitals, etc.
Carbonless paper, also known as pressure-sensitive paper, consists of top paper (CB), middle paper (CFB), and bottom paper (CF). It utilizes the principle of a chemical reaction between the color-forming agent in microcapsules and the acidic clay in the color-developing layer. During printing, pressure from the print head on the paper surface achieves the color development effect. The commonly used number of color-developing layers ranges from 2 to 6.
When purchasing carbonless paper, you should observe whether the outer packaging is damaged (if the outer packaging is damaged or deformed, it may cause the paper inside to not develop color properly). B: Open the outer packaging to check if there is a certificate of conformity inside, whether the paper is damp or wrinkled, and whether the color development meets your requirements (usually tear off a piece and write a few words on it in the normal way, then check the color development of the last layer). C: Confirm that the Specification of the printing paper is what you need to avoid unnecessary waste and trouble.
Common Specifications for carbonless paper are 80-column or 132-column, as well as special Specifications (width, length, horizontal divisions, vertical divisions, etc.). The most commonly used is the 80-column, with a Size of: 9.5 inches X 11 inches (with holes on both sides, 22 holes per side, with a hole spacing of 0.5 inches between every two holes), approximately equal to 241 mm X 279 mm. 80-column paper is usually divided into three Specifications:
