Each type of paper has its own characteristics: Newsprint is not coated, most of it is made from mechanical pulp, weights are generally from 38 g to 48 g; calendered magazine paper is calendered by newsprint and is not coated, most of them More than 42 grams of mechanical pulp, but this type of paper is still relatively rare in mainland China; offset paper is not coated, most of it is chemical pulp, more than 70 grams, domestic use is very common; Lightweight coated paper (LWC) is a single Layer coating, mostly based on mechanical pulp, glossy. There is also a high white light coated paper that is improved on the basis of the original light-coated paper, so that it has a better whiteness; MWC is a double-layer coating, most of which is made by mechanical pulp, g More than 70 grams of weight; coated paper is the most familiar paper, most of them are chemical pulp paper, coated with single, double and three layers, and its coating and paper surface treatment, etc., different paper mills There are different technologies and the quality is very different. In fact, coated paper and mid-coated paper have intersecting parts. Double-layer and multi-layer coating of coated paper have better quality than that of medium-coated paper, but mid-coated paper is better than single-layer coating of coated paper. This is because The shading rate of pulp is better than that of chemical pulp. As for the three-layer coated coated paper, it was also known as true powder.
So what kind of paper does the magazine use?
Generally speaking, high-end apparel and life-themed magazines mostly use coated paper with a weight of ≥ 70 grams and medium-coated paper; high-quality monthly magazines and professional magazines use medium- and medium-duty light coated paper with a weight of ≥ 70 grams; Monthly magazines and weekly magazines of quality often use high-white light-coated paper and light-coated paper with a grammage of ≥60 grams. Weekly magazines and comprehensive magazines with large circulations generally use light-coated paper and calendered paper with a weight of ≥65 grams.
In addition, the following rules are generally used in the selection of grammage: 36-54 grams of paper are generally used in high circulation magazines and catalogues; 60-80 grams in higher quality monthly publications; 65-150 grams in professional magazines and customer magazines; The quality magazine is 75-115 grams. Of course, this is only a general analysis. Various magazines will have various specific changes in the specific printing orders.
The last thing I want to say is that current magazine papers are moving toward low weight, good whiteness, and printability. This will not only reduce the amount of paper used, but also save further by reducing the cost of mailing.
