As an information medium, printing is loved by many enterprises. With the rapid development of science and technology, the printing industry as electronic publications, paper publicity materials, or shopping centers of many enterprises are inseparable from its publicity. Therefore, we must know how to distinguish the quality of album printing.

目前，还没有有效的方法来区分相册印刷的质量。在这个时候，我们需要学习如何区分纸张的材料和重要性。我们还需要知道印刷手册和相册时主要使用哪种纸张，并且可以用肉眼识别。一般来说，主要用纸是白纸、双铜纸、双胶印纸等相册印刷品。

At present, there is no effective method to distinguish the quality of photo album printing. At this time, we need to learn how to distinguish between the material and the importance of paper. We also need to know what kind of paper is mainly used when printing manuals and albums, which can be identified with the naked eye. Generally speaking, the main paper is white paper, double copper paper, double offset paper and other photo album prints.

一、好纸给人很舒服的感觉。纸的表面没有诸如草霉、沙子、裂缝、洞等缺陷。好的纸不一定特别白，但手感特别好。感觉厚度均匀，光滑细腻，不粗糙。触摸玻璃表面，手感柔软粗糙。

1、 Good paper makes you feel comfortable. The surface of the paper is free from defects such as mildew, sand, cracks and holes. Good paper may not be particularly white, but it feels great. Feel the thickness is uniform, smooth and delicate, not rough. Touch the glass surface, feel soft and rough.

二、它可以通过摇动纸张和蘸墨试纸来区分：摇动纸张就是拿起纸张轻轻摇动。如果摇动产生很大的噪音，那么纸张必须是脆而有弹性的。如果用于印刷书画书刊，效果很差。用刷子蘸墨水试纸，轻轻地点击试纸。好纸的反应是快速吸墨、分散均匀、墨边不锯齿、干燥快等。油墨完全渗透到纸纤维上，然后第二次点击，油墨干燥效果明显，油墨清澈。

2、 It can be distinguished by shaking the paper and dipping the ink test paper: shaking the paper means picking up the paper and shaking it gently. If shaking makes a lot of noise, the paper must be crisp and elastic. If it is used for printing calligraphy, painting, books and periodicals, the effect is very poor. Dip the ink test paper with a brush and tap it gently. The reaction of good paper is fast ink absorption, uniform dispersion, non serrated ink edge, fast drying and so on. Ink completely penetrated into the paper fiber, and then the second click, the ink drying effect is obvious, the ink is clear.

三、在印刷中，使用的机器是四色机直接印刷或彩色印刷。如果是彩色印刷，会有或多或少的双阴影。在装订过程中，无论装订或装订是否到位，裁切都是均匀的，内页的页数、上下几页的页数等。

3、 In printing, the machine used is a four-color machine direct printing or color printing. If it's color printing, there will be more or less double shadows. In the process of binding, no matter whether the binding or binding is in place, the cutting is uniform, the number of pages in the inner page, the number of pages in the upper and lower pages, etc.

四、纸张的克数与纸张的厚度有很大关系。纸越重，纸就越厚。

4、 The number of grams of paper is closely related to the thickness of the paper. The heavier the paper, the thicker the paper.

，相册的质量要保证纸张的质量，了解纸张的特性，充分利用印刷材料，在相册印刷中区分纸张的外观质量，从而获得良好的印刷质量。纸张的外观是由一定面积的单张纸或纸带组成，相册印刷的质量可以根据人们的触摸来感受。

First of all, the quality of album should ensure the quality of paper, understand the characteristics of paper, make full use of printing materials, distinguish the appearance quality of paper in album printing, so as to obtain good printing quality. The appearance of paper is composed of a certain area of single paper or paper tape. The quality of photo album printing can be felt according to people's touch.
