Which one is good at printing picture albums and what steps should be taken? Therefore, starting from the current situation of packaging, this paper analyses the importance of packaging structure design, and studies the color of packaging.

　　一、注意上水的变化

　　First, pay attention to the change of water supply

　　①注意正式印刷初期上水的变化。试印时的上水量和进入正式印刷后的上水量，多少都会有些变化，一定要一边注意观察样张有无重影、水扛子，一边注意调解印版的给水量。

　　Attention should be paid to the change of water supply in the initial stage of formal printing. There will be some changes in the amount of water used in trial printing and after entering the formal printing. We must pay attention to the duplication of sample sheets and water carriers, and adjust the amount of water supplied to the printing plate at the same time.

　　②注意正式印刷过程中上水的变化。要密切注意机器主体发热和车间内的通风状况给上水带来的影响，酒精润版要注意润湿系统冷却装置，控制好润湿液的温度，上水过少，会使印版起脏；上水过多将引起油墨乳化，会带来一系列问题。比如印品无光泽，纸张伸缩而套印不准，延缓油墨的干燥等。

　　(2) Pay attention to the change of water supply in the process of formal printing. It is necessary to pay close attention to the influence of the heating of the main body of the machine and the ventilation condition in the workshop on the water supply. Alcohol wetting plate should pay attention to the cooling device of the wetting system, control the temperature of the wetting liquid well, and the printing plate will be dirty if the water supply is too little. Excessive water supply will cause ink emulsification, which will bring a series of problems. For example, the gloss of printing products, paper flexibility and improper overprinting, delaying the drying of ink and so on.

　　二、注意油墨的变化

　　2. Pay attention to the change of ink

　　①注意墨斗的油墨。墨斗的油墨从墨斗辊和墨斗刮刀之间的缝隙传出，是由油墨的自重而自然被挤压出来的。因此，墨斗中油墨量的多少，直接影响油墨的输出量。所以，要注意让墨斗中保持一定量的油墨。另外，印刷油墨具有触变性质。放置在墨斗中较久，流动性会逐渐变差，因而，要经常用墨刀在墨斗中搅拌，或者安装油墨搅拌器。

　　Pay attention to the ink in the ink bucket. Ink from the bucket roll and the bucket scraper gap between the ink, is the weight of the ink and is naturally squeezed out. Therefore, the amount of ink in ink bucket directly affects the output of ink. Therefore, attention should be paid to keeping a certain amount of ink in the ink bucket. In addition, printing ink has thixotropic properties. If placed in ink bucket for a long time, the fluidity will gradually deteriorate. Therefore, it is necessary to mix in ink bucket with ink knife or install ink mixer.

　　②防止油墨在机器上干燥。长时间停机如吃饭、休息时，墨辊上的油墨和墨斗中的油墨表面就会干燥。可使用干燥抑制剂喷在需要防止干燥处。

　　Prevent ink from drying on the machine. When the machine is shut down for a long time, such as eating and resting, the ink on the roller and the ink surface in the ink bucket will dry. Drying inhibitors can be sprayed at places where drying needs to be prevented.

　　③注意油墨均匀，印刷品的密度视上水量、室温、机器速度不同而发生变化。应经常与标准样张进行对比检查。注意防止出现墨色不均匀现象。

　　(3) Pay attention to the uniformity of ink, the density of printed matter changes depending on the amount of water, room temperature and machine speed. It should be checked regularly in comparison with the standard sample sheet. Attention should be paid to preventing the uneven ink color.

　　④保持润湿液的pH值，油墨中添加了辅助剂后，容易影响润湿液的pH值，如pH值增大则易造成印版起脏，因此要特别注意。

　　(4) Maintaining the pH value of the wetting solution and adding auxiliary agent in the ink will easily affect the pH value of the wetting solution. If the pH value increases, it will easily cause the printing plate to become dirty, so special attention should be paid to it.

　　日常生活中的包装大部分都是千篇一律的形态。包装设计应该把包装的结构设计与包装的装潢设计二者结合起来。主要介绍包装的结构设计。纸盒包装形体可以归纳为几个基本形体，然后,在它的基础上对结构进行改变或改良。

　　Packaging in daily life is mostly in a uniform form. Packaging design should combine packaging structure design with packaging decoration design. This paper mainly introduces the structure design of packaging. Carton packaging can be summarized into several basic forms, and then, on the basis of which, the structure can be changed or improved.
