What is the printing paper material and gram?

Printing generally exists in every field of our life now. What is the instruction printing paper material and gram? I believe it is relatively difficult for many people to understand when they are not engaged in the printing industry. Let me talk about the professional knowledge in manual printing today. Let more and more people know such things.

The first step is to know what kinds of paper are commonly used in printing product manuals. The most commonly used papers are double offset paper, double copper paper and matte paper. You can at least tell what kind of material it is with the naked eye.
1. Double gummed paper, also known as writing paper, is similar to the kind of paper used for printers. It looks relatively white and feels relatively smooth, but the surface layer of the paper is still slightly unsmooth compared with double copper paper and matte paper. If you look carefully, you can see the texture and grain of the paper very clearly.
2. Double copper paper, which looks relatively bright, has a layer of milky white coating on the surface, which is smooth and smooth to touch, and can reflect light when placed in the sun or light. We usually see the company brochure, supermarket page this is generally double copper paper to print.
3. The composition principle of matte paper and double copper paper is the same, only the coating without removing the surface layer is different. The surface layer of matte paper is not reflective, and it feels the same with double copper paper by hand, which is relatively fine and smooth. It is commonly used in the printing of picture books with relatively strong artistic sense.All the above are about what is the specification of the printed paper material and grams of articles to share.
