What are the quality standards of dot matrix computer printing paper

With the continuous development of computer technology, printing technology is also improving. Among the many printing methods, computer dot matrix printing paper is popular because of its low price, high reliability, and wide application range. However, when choosing dot matrix printing paper for computers, you need to pay attention to its quality standards to ensure that the printed documents are clear, bright and durable. So, what are the quality standards for computer dot matrix printing paper?
The following will introduce from the aspects of paper material, density, flatness, whiteness and durability.

1. Paper material
Computer dot matrix printing paper usually uses composite paper, which is composed of two or more layers of base paper of different materials. It is characterized by high strength, good gloss, not easy to deform, etc. When choosing a paper material, attention needs to be paid to its fiber quality and wood pulp content. Paper with good fiber quality has a long life, while paper with less wood pulp has high whiteness and bright colors.


2. Density
The density of computer dot matrix printing paper directly affects the printing effect. The higher the density, the less prone to pinholes and debris. Generally speaking, paper with a density above 60 g/m2 is more suitable for computer dot matrix printing. Too low or too high density will affect the printing effect.


3. Flatness
The flatness of dot matrix printing paper refers to the flatness of the paper surface. If the surface of the paper is uneven, problems such as “skewed printing” and “repeated printing up and down” are prone to occur. Therefore, when choosing dot matrix printing paper for computers, it is necessary to choose paper with a flat surface.


4. Whiteness
The whiteness of computer dot matrix printing paper refers to the brightness of the reflected light of the paper under sunlight. The higher the whiteness, the brighter the color. When using computer dot matrix printing paper, it is generally necessary to choose paper with a whiteness of more than 80%, so as to ensure that the printed documents are bright and clear in color.

5. Durability
The durability of computer dot matrix printing paper refers to its anti-aging, waterproof, anti-pollution and other properties. Generally speaking, computer dot matrix printing paper needs to have good durability to ensure that the printed documents are not easy to fade, damage, etc.

In short, the quality standards of computer dot matrix printing paper include paper material, density, flatness, whiteness and durability, etc. Choosing the right dot matrix printing paper for computer can ensure better quality of printed documents, brighter colors and more lasting. In addition to the above standards, you also need to pay attention to whether the size of the paper meets the requirements of the printer, and whether the surface of the paper is flat and smooth. When purchasing computer dot matrix printing paper, it is recommended to choose a brand with a good reputation to ensure the quality and stability of the product.
