How to choose A4 copy paper?

First, the tiger balm-ordinary copy paper

The characteristic of tiger balm is that it can be used everywhere, but "treating the symptoms rather than curing the root cause" can only solve the urgent need.

Ordinary copy paper is like tiger balm, which is cheap and commonly used. Printing text, tables, legends and other materials is essential. Although its technical content is low, it is fully qualified for general document printing. In the absence of other printing paper, it can also play a temporary "reassuring" role. The most important thing is that it also has a huge advantage, that is, its cost is low. Generally, the price of a pack of A4 copy paper (500 sheets per pack) ranges from 15 yuan to 25 yuan. So all kinds of paper can be less in the office, but ordinary copy paper can't be less. The following are the things you should pay attention to when buying and using:

1, know something about eye protection, not the whiter the better.

What kind of ordinary printing paper is the best? I think most people will answer, "One white covers all the ugliness", the whiter the better. Is that so? Not necessarily. It is true that sometimes extra white paper will cover up the problem, but for people who often use copy paper, extra white paper may damage their health. According to the color, copy paper can be divided into bleached and white. Bleached paper is whiter, and printing with words may be better. It is recommended for external use, because it will look good. However, this kind of white copy paper is recommended for ordinary household or company use, which is beneficial to protect eyes, because under the light, too white paper will reflect strong glare. Experts pointed out that too white copy paper will be dazzling and even affect vision. In addition, some manufacturers have also introduced color copy paper, which is more expensive than ordinary white paper. Users in need can pay attention to it in the market.

2. The purchased weight should be appropriate.

According to the weight, copy paper is usually divided into four common grades (70g, 80g, 90g, 100g). The greater the weight, the more durable it is. It should be noted that you must avoid buying copy paper weighing less than 60 grams. This kind of paper is very thin and wrinkles easily. Moreover, the friction coefficient between papers is also relatively large, which is easy to cause multi-page feed and paper jam, affecting the life of the printer. From the point of view of economy and applicability, 70 grams of neutral copy paper should be enough for general office paper.

3, choose and buy to distinguish, neutral and acidic.

According to the production process, copy paper can be divided into acid paper and neutral paper, and consumers should recognize this when buying. Neutral paper is 100% wood pulp. Because wood pulp fibers are long and have good bonding force between fibers, the fibers are not easy to fall off when rubbing against equipment, that is, it is not easy to produce dust, which has a good protection effect on machines and operators. In addition, neutral paper is non-corrosive, which makes the paper not easy to fade, can be stored for a long time, has no static electricity and is harmless to human health. Acid paper is a mixed pulp of wood pulp and straw pulp, which has short fibers and is easy to produce dust. Acid paper has corrosive effect, which makes it easy to change color, difficult to store for a long time, and easy to produce acid gas at high temperature, which is harmful to human body. These two kinds of paper can be completely distinguished by hand feeling, and consumers will not be deceived as long as they pay a little attention when buying.

The quality of printing is not only related to the printing resolution, the ink or toner cartridge used, but also the choice of printing paper.

At present, the commonly available printing paper in the market is mainly divided into ordinary copy paper, ink-jet printing paper, photo printing paper, photo sticker printing, transparencies printing and transfer paper special paper.

How to choose printing paper is a headache. What should I pay attention to when buying? What brand is the best? Asian businessmen compared the medicinal oil that we usually use the most, and put the printing paper in the right place so that everyone can understand it.

Second, Baoxin oil-ordinary inkjet printing paper

Features of Baoxin Oil: Gu Ming's meaning is "Baoxin", so it is very reassuring to hear the name. The effect of Baoxin oil is as much as Wanhua oil, but it is more honest than Wanhua oil, and the therapeutic effect will be much more significant, and it is targeted to a certain extent, and of course it is quite expensive.

Ordinary inkjet printing paper, such as Baoxin Oil, is aimed at high-quality printing needs, such as contracts or tenders, general mixed text and so on. Its printing resolution is generally 360dpi, and its price is higher than that of copy paper. It can be used in xerography, laser printing, hot melt printing, CAD inkjet printing, fax and other fields, and has a wide range of applications, making it the first choice for many inkjet printer users.
