How to distinguish the pros and cons of computer printing paper

Time : 2022-03-29 Hits : 4

Computer printing paper is the most commonly used type of paper in life. Different size specifications refer to the paper that is cut into a certain size after it is made. In the past, the size of the paper was expressed by how many "opens". Now a unified national standard is usually adopted, which stipulates that the size of the paper is expressed by A0, A1, A2, etc.

A2 (4 open) 594mm×420mm;

A3 (8 open) 420mm×297mm;

A4 (16 open) 297mm×210mm;

A5 (32 open) 210mm×148mm;

A6 (64 open) 144mm×105mm;

The paper specifications of the A series are characterized by:

A0, A2, …, A5, all paper sizes have the same aspect ratio.

After A0 is cut, you can get 2 A1s, A1 can get 2 A2s, and so on.

The most commonly used computer printing paper in the office, especially for administrative personnel and procurement, is often troubled by the desire to buy low-quality computer printing paper at a low price.

So, how to choose a good computer printing paper?
【Moisture content】

Computer printing paper usually has a water content of about 5%. Generally, the water content of acid printing paper is as high as 8-10%. The water content of acid printing paper is high, the density is not enough, the paper is too soft, easy to jam, and acid steam is generated at high temperature. , Corrosion of the copier and harmful to the human body. In wet seasons, paper jams often occur, the printing is not clear, the body is dusty, the paper is deformed, and there is more paper.

【PH value】

At present, acid printing paper is mixed with computer printing paper, and acid paper is filled with talc and aluminum phosphate. Talc powder has large particles and is hard and has poor binding force with pulp fibers, causing paper powder to fall off, wear copiers, and aluminum sulfate in the air. It combines with water molecules to produce acid, corrodes the paper and becomes brittle and yellow, and produces acid steam at high temperature in the copier, which corrodes the copier and damages human health.


Computer printing paper that has not been treated with anti-static chemical treatment or has a low level of treatment technology will generate electrostatic adsorption and multiple sheets of paper will be fed, especially in dry seasons. On the paper, in the paper inlet and in the copier body, spots are produced when copying.


The higher the density of computer printing paper, the better the stiffness and moisture resistance. The acid printing paper is thicker, soft, rough, and has a large water content, which will cause more damage to the copier.


The look and feel is smooth, delicate, bright, and there is no dark feeling. Touch: It feels smooth, firm and elastic. Shake: Shake a stack of paper on a dark table to see if there is white powder; how is the stiffness. Tear: strength, toughness, transverse direction, wire direction is correct.

Master the above methods, you can easily distinguish the pros and cons of computer printing paper.
