Printing is a routine operation in many people’s daily work, and the output quality of the printer is not only related to the performance of the printer itself, but also related to the computer paper we choose in daily life. In order to control procurement costs, many enterprises blindly covet low prices, and what they buy is not only inferiorcomputer paper, but also problems such as damp paper, electrostatic reaction and wet writing, which will also arouse the annoyance of staff.We have a wide range of computer papers, such asmulti-ply computer paperandprinted computer paper，etc.
How to buy a satisfying computer paper?
1. Print paper thickness.
Ordinary copy paper can be distinguished by weight, and the common ones are 70g, 80g, 90g and 100g. Usually, 70g computer paper can meet most office printing needs. Copy paper weighing less than 60g is not recommended to be purchased. Because these papers are relatively thin, they are easy to wrinkle when used on the printing and output equipment, and the friction coefficient between the papers is also relatively large, which is easy to cause multi page feeding and paper jam, which will seriously affect the service life of the equipment.
The thinner the paper with the same weight, the higher the processing level, the higher the density, and the better the moisture resistance, stiffness, smoothness and copying effect. The weight of a package of 70g A4 copy paper (standard 500 sheets) is 2. 19 kg; And the weight of a pack of 80 g A4 copy paper (standard 500 sheets) is 2. 5 kg. If the weight is insufficient, it indicates that the weight is not sufficient or the number of sheets is defective.
2. Neutral and acid should be distinguished.
According to the production process of copy paper, it can be divided into acid paper and neutral paper. Neutral paper is 100% wood pulp. Because the wood pulp fiber is long and the bonding force between the fibers is good, the fiber is not easy to fall off during friction with the equipment, that is, it is not easy to generate dust, which has a good protective effect on the machine and the operator, and has no corrosion, so that the paper is not easy to fade, can be stored for a long time, will not carry static electricity, and is harmless to human health.
Since the acid copy paper is a mixture of wood pulp and straw pulp, the straw pulp fiber is short, which is easy to generate dust. The acid paper has corrosive effect, making the paper easy to change color, difficult to preserve for a long time, and easy to produce acid gas at high temperature, which is harmful to human body.
3. Selection of white background.
Copy paper can be divided into two categories according to color: bleached and natural white. Bleached paper is whiter. When text is printed, the effect will be better and the overall beauty will be increased. It is recommended to use it externally. If it is used in a family, an individual or a company, it is recommended to choose white copy paper, which is conducive to protecting eyes, because under the light, too white paper will reflect strong glare, produce dazzling, and even affect vision if used for a long time.
4. The paper is hard.
Although the grams of some papers are appropriate, they are not necessarily suitable for use by copiers. The reason is that weight and stiffness are two different things, and often due to poor stiffness, they will wrinkle and block slightly when they encounter resistance during transportation.
5. Surface luminosity.
Generally, it is electrostatic, and the surface brightness is slightly high. If it is too smooth, it is unfavorable for fixing, and it is not easy to cure. Single adhesive tape can be used as required. If there is a duplicator for double-sided copying, double adhesive tape is better. The surface of copy paper should be white.
