Printing paper specification

The so-called opening number means cutting into several parts. For example, an 8-size piece of paper is 1/8 (cut three times). Before designing, the paper size should be selected first, because the printing machine can only use several kinds of paper (generally fully open and fully open), and then cut it into the required size by the machine after printing once, so don't use special specifications other than the following table if it's all right, so as to avoid paper printing dissatisfaction and waste of space.

Because the machine grabs the paper and moves it, the edge of the paper cannot be printed, so the original size of the paper will be larger than the actual size, and the blank part of the edge will be cut off after printing, so there will be a difference between the full size and the cut size. If the poster is intentionally left blank, you can choose not to cut it.

There are many kinds of printed matter, and different printed matter often needs different kinds of paper. Here are some varieties and specifications of commonly used printing paper.

1. letterpress paper

Letterpress paper is the main paper for letterpress printing books and magazines. Embossed paper can be divided into four grades according to the composition ratio of paper materials: 1, 2, 3 and 4. The quantity of paper represents the quality of paper. The greater the quantity, the worse the quality of paper. Relief printing paper is mainly used in relief printing machines. The characteristics of this kind of paper are similar to those of newsprint, but they are not exactly the same. Because the pulp-pulp ratio is better than that of newsprint, the fiber structure of letterpress paper is relatively uniform, the gaps between fibers are filled with a certain amount of fillers and sizing agents, and after bleaching, the adaptability of this paper to printing is formed. Slightly different from newsprint, its ink absorption is not as good as newsprint, but it has the characteristics of uniform ink absorption; The water resistance and whiteness of paper are better than newsprint. Relief paper has the characteristics of uniform texture, lint-free, slightly elastic, opaque, slightly water-resistant and certain mechanical strength.

Weight: 49 ~ 60) 2g/m2.

Flat paper specifications: 787×l092, 850×ll68, 880xl230 and some special paper sizes.

Web specifications: 787mm wide, 1092mm wide, 1575mm wide and 60m ~ 80OOM long.

2. Ink

Newsprint, also known as white newspaper, is the main paper of newspapers and books. Newsprint is characterized by its softness and elasticity; Good ink absorption, ensuring that the ink can be quickly fixed on the paper; After calendering, both sides of the paper are smooth and lint-free, so that the printed matter on both sides is clear and full; Have certain mechanical strength; Good opacity; Suitable for high-speed rotary printing. This paper is made of mechanical pulp (or other chemical pulp) and contains a lot of lignin and other impurities. Not suitable for long-term storage. If the paper is stored for too long, it will turn yellow and brittle, and its water resistance is poor, so it is not suitable for writing. Printing ink or book ink must be used, the viscosity of the ink should not be too high, and the water content of the page must be strictly controlled during lithography.

Weight: 49 ~ 52) 2g/m2

Specification of plain paper: 787× 1092mm, 850x ll68, 880x l230.

3. Offset paper

Offset paper is mainly used for lithographic (offset) printing machines or other printing machines to print high-grade color printed matter, such as color pictorial, album, poster, color printing trademark and some advanced books, as well as book covers and illustrations. Offset paper is divided into special number, 1 number and No.2 according to the proportion of pulp. It has one side and two sides, and there are two grades of super calendering and ordinary calendering. Offset paper has small flexibility, uniform ink absorption, good smoothness, compact and opaque texture, good whiteness and strong water resistance. Conjunctival offset printing ink and good quality lead ink should be selected. The viscosity of ink should not be too high, otherwise there will be powder removal and galling. Also to prevent the back from getting dirty, generally use antifouling agent, dusting or lining paper.

Coated paper is mainly used for printing picture books, covers, postcards, exquisite product samples and colored trademarks. When printing coated paper, the pressure should not be too high, and offset printing resin ink and bright ink should be used. In order to prevent the back from sticking dirty, methods such as adding antifouling agent and dusting can be adopted.
