I. how to distinguish the printed paper material1、首先要晓得印刷画册时主要用哪些纸，并且能用肉眼区分得出来。主要用到的有哑粉纸、双铜纸、双胶纸。
1. First of all, we should know which paper is mainly used in printing picture books, and can distinguish them with the naked eye. The main uses are matte paper, double copper paper and double offset paper.
2. There is a layer of milky white coating on the surface of the double copper paper, which looks very bright, feels very smooth, and reflects light in the light. The company's brochures are usually printed on double copper paper. Dumb powder paper and double copper paper have the same composition principle, but the coating on the surface is different. The appearance of dumb powder paper does not reflect light, and feels more delicate and smooth. It is mainly used for the printing of some picture books with strong artistic sense. Double offset paper, i.e. writing paper, is similar to that used in printers. It is whiter and smoother. With the naked eye, we can clearly see the texture of the paper. The paper surface is slightly rougher than that of copper paper and dumb powder paper.
3. The gram number of paper has a great relationship with the thickness. The heavier the paper is, the thicker it is.
There are some subtle differences in the thickness of different brands of paper. When the printing factory provides samples, you'd better ask which brand of paper it is first. When you have a certain understanding of the printing materials of the purchased illustrated books and picture books, you can correctly judge whether the samples of the printing factory are different from the illustrated books in your hands.
How to check the quality of paper in printed picture books1、反射光平视检查
1. Reflection light head up inspection
Lay the paper on the inspection table or desktop, and use the reflected light to check the color, whiteness, flatness and lubricity of the paper with the naked eye about 30cm away from the paper surface. Pay attention to check the paper for dust, spots, holes, holes, wrinkles, wrinkles, splits, cracks, corners, dirty spots, seersucker, pulp block and other hard blocks. During the inspection, the eyes are looking straight at the paper. Generally, it stops under the ordinary indoor light. It is not suitable to stop under the intense light or the direct sunlight. If necessary, it can also stop viewing with the help of a normal magnifying glass.
2. Perspective inspection
Look after the paper against the light source, let the light pass through the paper, and check the quality of the paper with the naked eye. Check the average and opaque level of the fiber tissue of the paper, and check the quality of the paper. Check the average and opaque levels of the fibrous tissue on the paper.
3. Oblique inspection
Some papers have to be examined with a slant to see the problem. Oblique inspection is to use both hands to improve or lower one side of the paper, and to look at the paper from different angles to find defects or lack of paper appearance quality.
4. Hand touch inspection
Hand touch examination is reflected by feeling the contact of organs. Hand inspection can find the shortcomings of different thickness of paper.
5. Audio inspection
Hearing inspection is to use hand vibration or rubbing paper, and use ears to listen to its voice to judge some properties of paper.
The strength and toughness of paper is usually called the "body bone" of paper. The stronger the "body bone" is, the louder the paper noise is, and it is not easy to break under tension. The sound of paper made from different materials is also different. Ordinary wood pulp paper is more bright, pulp paper is more turbid, and cotton pulp paper is more mild. The noise of the paper consumed by different pulping methods is also different. The noise of the paper made by ordinary kraft pulping is higher than that of bisulfate pulping.
