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、注意上水的變化

　　First, pay attention to the change of water supply

　　①注意正式印刷初期上水的變化。試印時的上水量和進入正式印刷后的上水量，多少都會有些變化，一定要一邊注意觀察樣張有無重影、水扛子，一邊注意調解印版的給水量。

　　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注意正式印刷過程中上水的變化。要密切注意機器主體發熱和車間內的通風狀況給上水帶來的影響，酒精潤版要注意潤濕系統冷卻裝置，控制好潤濕液的溫度，上水過少，會使印版起臟；上水過多將引起油墨乳化，會帶來一系列問題。比如印品無光澤，紙張伸縮而套印不準，延緩油墨的干燥等。

　　(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、注意油墨的變化

　　2. Pay attention to the change of ink

　　①注意墨斗的油墨。墨斗的油墨從墨斗輥和墨斗刮刀之間的縫隙傳出，是由油墨的自重而自然被擠壓出來的。因此，墨斗中油墨量的多少，直接影響油墨的輸出量。所以，要注意讓墨斗中保持一定量的油墨。另外，印刷油墨具有觸變性質。放置在墨斗中較久，流動性會逐漸變差，因而，要經常用墨刀在墨斗中攪拌，或者安裝油墨攪拌器。

　　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防止油墨在機器上干燥。長時間停機如吃飯、休息時，墨輥上的油墨和墨斗中的油墨表面就會干燥。可使用干燥抑制劑噴在需要防止干燥處。

　　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注意油墨均勻，印刷品的密度視上水量、室溫、機器速度不同而發生變化。應經常與標準樣張進行對比檢查。注意防止出現墨色不均勻現象。

　　(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保持潤濕液的pH值，油墨中添加了輔助劑后，容易影響潤濕液的pH值，如pH值增大則易造成印版起臟，因此要特別注意。

　　(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.

　　日常生活中的包裝大部分都是千篇一律的形態。包裝設計應該把包裝的結構設計與包裝的裝潢設計二者結合起來。主要介紹包裝的結構設計。紙盒包裝形體可以歸納為幾個基本形體，然后,在它的基礎上對結構進行改變或改良。

　　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.
