画册印刷要注意做到哪几步?

  画册印刷哪家好,需求做到哪几步?因而,本文主要从包装的现状动身,剖析包装构造设计的重要性,并对包装的颜色停止研讨。

  Which one is good for album printing and what steps should we take? Therefore, this paper starts from the current situation of packaging, analyses the importance of packaging structure design, and discusses the color of packaging.

  一、留意上水的变化

  First, pay attention to the change of water supply

  ①留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,几都会有些变化,一定要一边留意察看样张有无重影、水扛子,一边留意调解印版的给水量。

  (1) Pay attention to the change of water supply in the initial stage of formal printing. There will be some changes in the amount of water supplied during the trial printing and after entering the formal printing. We must pay attention to the duplication of sample sheets and water carriers, as well as the adjustment of the amount of water supplied to the printing plate.

  ②留意正式印刷过程中上水的变化。要亲密留意机器主体发热和车间内的通风情况给上水带来的影响,酒精润版要留意润湿系统冷却安装,控制好润湿液的温度,上水过少,会使印版起脏;上水过多将惹起油墨乳化,会带来一系列问题。比方印品无光泽,纸张伸缩而套印不准,延缓油墨的枯燥等。

  (2) Pay attention to the change of water supply in the process of formal printing. Alcohol wetting plate should pay close attention to the cooling installation of wetting system, control the temperature of wetting liquid, too little water will make the printing plate dirty; too much water 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 dryness of ink, and so on.

  二、留意油墨的变化

  2. Pay attention to the change of ink

  ①留意墨斗的油墨。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。因而,墨斗中油墨量的几,直接影响油墨的输出量。所以,要留意让墨斗中坚持一定量的油墨。另外,印刷油墨具有触变性质。放置在墨斗中较久,活动性会逐步变差,因此,要经常用墨刀在墨斗中搅拌,或者装置油墨搅拌器。

  Watch out for the ink in the ink bucket. Ink from the bucket roller 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, we should pay attention to letting ink bucket adhere to a certain amount of ink. In addition, printing ink has thixotropic properties. If placed in the ink bucket for a long time, the activity will gradually deteriorate. Therefore, the ink knife should be often used to stir in the ink bucket, or the ink mixer should be installed.

  ②避免油墨在机器上枯燥。长时间停机如吃饭、休息时,墨辊上的油墨和墨斗中的油墨外表就会枯燥。可运用枯燥抑止剂喷在需求避免枯燥处。

  (2) Avoid the dullness of the ink on the machine. When the machine stops for a long time, such as eating and resting, the ink on the roller and the ink in the ink bucket will be dull. It can be sprayed with a dull inhibitor to avoid the dull place where the demand is.

  ③留意油墨平均,印刷品的密度视上水量、室温、机器速度不同而发作变化。应经常与规范样张停止比照检查。留意避免呈现墨色不平均现象。

  (3) Pay attention to the average ink, the density of printed matter varies depending on the amount of water, room temperature and machine speed. It should be checked regularly with the standard sample. Be careful to avoid ink inequality.

  ④坚持润湿液的pH值,油墨中添加了辅助剂后,容易影响润湿液的pH值,如pH值增大则易形成印版起脏,因而要特别留意。

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

  日常生活中的包装大局部都是千篇一概的形态。包装设计应该把包装的构造设计与包装的装潢设计二者分离起来。主要引见包装的构造设计。纸盒包装形体能够归结为几个根本形体,然后,在它的根底上对构造停止改动或改进。

  Packaging in everyday life is mostly a one-size-fits-all form. Packaging design should separate packaging structure design from packaging decoration design. This paper mainly introduces the structure design of packaging. The carton packaging form can be reduced to several fundamental forms, and then, on the basis of which, the structure can be changed or improved.
