Printing paper specifications

p>

The so-called number of openings means cutting into several parts. For example, an 8-opening paper is 1/8 the size of the full opening (cut in half three times). Before designing, you must first select the paper size, because the printing machine can only use a few types of paper (usually full open, chrysanthemum open), and then use the machine to cut it into the required size after printing, so do not use the table below if you have nothing to do Special specifications other than that to avoid wasting space due to unsatisfactory printing on paper.

Because the machine needs to pick up and feed paper, the edges of the paper cannot be printed. Therefore, the original size of the paper will be larger than the actual specification. Wait until printing is completed before cutting the blank edges. Dropped, so there is a difference between full size and cropped size. If the poster intentionally leaves a white border, you can choose not to cut it.

The number of the paper represents the quality of the paper. The larger the number, the worse the paper quality. Letterpress printing paper is mainly used by letterpress printing machines.

This paper has properties similar to, but not identical to, newsprint. Since the ratio of paper pulp and the tapping of pulp are better than newsprint, the fiber structure of letterpress paper is relatively uniform. At the same time, the gaps between fibers are filled with a certain amount of filler and glue, and have also been bleached, which forms The adaptability of this paper to printing. It is slightly different from newsprint. Although its ink absorption is not as good as newsprint, it has the characteristics of uniform ink absorption; its water resistance and paper whiteness are both better than newsprint. Letterpress paper has the characteristics of uniform texture, lint-free, slightly elastic, opaque, slightly water-resistant, and certain mechanical strength.

Weight: 49～60)±2g/m2.

Specifications of flat paper: 787×l092mm, 850×ll68mm, 880xl230mm; and some special size paper.

This kind of paper is produced from mechanical wood pulp (or other chemical pulp) and contains a large amount of lignin and other impurities. Not suitable for long-term storage. If stored for too long, the paper will turn yellow, become brittle, have poor water resistance, and be unsuitable for writing. Newspaper ink or book ink must be used. The viscosity of the ink should not be too high. The moisture content of the page must be strictly controlled during offset printing.

Weight: 49～52) ±2g/m2

Offset paper has small elasticity, uniform absorption of ink, good smoothness, tight and opaque texture, and good whiteness. Strong water resistance. Conjunctival offset printing ink and better quality lead printing ink should be used. The viscosity of the ink should not be too high, otherwise powder removal and fuzzing will occur. To prevent dirt from sticking to the back, anti-fouling agents, powder spraying or lining paper are generally used.

Sexual and receptive conditions are very good. Coated paper is mainly used for printing albums, covers, postcards, exquisite product samples, and color trademarks. The pressure should not be too high when printing on coated paper, and offset resin-based inks and glossy inks should be used. To prevent dirt from sticking to the back, methods such as adding anti-fouling agents and powder spraying can be used.
