The common sense of choosing printing paper for DIY magazine pictures

Magazine paper generally includes newsprint paper, calendered magazine paper, offset paper, lightly coated paper, medium coated paper, and coated paper. This ranking reflects the quality of the paper from low to high, as well as the price. The following points need to be noted in the printing of magazines.

Each type of paper has its own characteristics: newsprint is not coated, most of it is made by mechanical pulp, and the weight is generally from 38 grams to 48 grams; calendered magazine paper is used to calender newsprint, and it is also uncoated. For mechanical pulping, over 42 grams, but this kind of paper is still relatively rare in mainland China; offset paper is not coated, most of it is chemical pulp, over 70 grams, which is very common in China; light coated paper (LWC) is single Layer coating, mostly based on mechanical pulp, is shiny. Now there is a kind of high-white light-coated paper, which is improved on the basis of the original light-coated paper, so that it has a better whiteness; medium-coated paper (MWC) is a double-layer coating, mostly made by mechanical pulp, g Weighs more than 70 grams; coated paper is the most familiar paper, most of it is made by chemical pulp, coated with single layer, double layer 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, there is a cross section between coated paper and intermediate coated paper. The double-layer and multilayer coating of coated paper have better quality than intermediate coated paper, but intermediate coated paper is better than the single-layer coating of coated paper. This is because of the mechanical The reason why the shading rate of pulp is better than that of chemical pulp. As for the three-layer coated art paper, some people call it true powder.

So what kind of paper does the magazine use?

Generally speaking, high-end clothing and life-themed magazines mostly use coated paper and medium coated paper with a weight of ≥70g; high-quality monthly and professional magazines use medium-coated paper and light coated paper with high whiteness, and the weight is ≥70g; generally Quality monthly and weekly magazines often use high-white light-coated paper and light-coated paper, with a grammage of ≥60 grams. Weekly and comprehensive magazines with large circulation generally use light-coated paper and calendered paper with a grammage of ≥65 grams.

In addition, the selection of gram weight generally has the following rules: high circulation magazines and product catalogs generally use 36-54 grams of paper; higher quality monthly magazines are 60-80 grams; professional magazines and customer magazines are 65-150 grams; Quality magazines are 75-115 grams. Of course, this is only a general analysis. Various magazines will have various specific changes in the specific printing order.

The last thing I want to say is that the current magazine paper is developing in the direction of low grammage, good whiteness and printability, which can not only reduce the amount of paper used, but also save further by reducing the cost of mailing.
