Each paper has its own characteristics: newsprint is not coated, most of it is made of mechanical pulp, from 38 grams to 48 g; pressed magazine paper is not coated, most are coated, but it is still rare in China; offset paper is not coated, most are chemical pulp, more than 70 grams, domestic use is very common; light coated paper (LWC) is a single layer coating, most of which is based on mechanical pulp, shiny. Now there is also a high white light coated paper, which is improved on the basis of the original light coated paper to make better whiteness; medium coated paper (MWC) is double coating, most of them with mechanical pulp, weighing more than 70 grams; coated paper is the most familiar paper, most are made of chemical pulp, coated with single layer, double layer and three layer, and paper surface treatment, different paper mills have different techniques and quality. In fact, there is a cross between coated paper and medium coated paper. The quality of double and multi-layer coated paper is better than that of medium coated paper, but the medium coated paper is better than the single layer coating of coated paper, because the shielding rate of mechanical pulp is better than that of chemical pulp. As for three layers of coated coated paper, also called true powder.
So what kind of magazine to choose from and what kind of paper?
Generally speaking, most magazines with high-grade clothing and life theme use 70 grams of coated paper and coated paper; high quality monthly and professional magazines use medium paper and light paper, which weigh 70 grams; general quality monthly and weekly often use high white paper and paper, weighing 60 grams; large circulation weekly and comprehensive magazines generally use light paper and light paper, which weigh 65 grams.
In addition, there are the following rules in the selection of weight: 36-54 g for high circulation magazines and catalogue; 60-80 g for higher quality monthly; 65-150 g for professional magazines and customer magazines; and 75-115 g for quality magazines. Of course, this is only a general analysis, a variety of magazines in the specific printing orders, there will be a variety of specific changes.
Finally, I would like to say that magazine paper is currently developing towards low gram weight, good whiteness and printing suitability, which can not only reduce the amount of paper, but also further save by reducing the cost of mailing.
