产品的销量由众多因素决定，比如产品质量，产品品牌，产品口碑等等，还有一项重要因素，那就是产品的印刷包装。精美的印刷包装会勾起人们的消费冲动，从而提升产品的销量。那么在进行印刷包装的时候，我们应该注意些什么。小编为大家总结了一些印刷包装注意事项，希望在您进行山东印刷包装的时候能够帮助到您。

The sales volume of products is determined by many factors, such as product quality, product brand, product reputation, and so on. Another important factor is the printing and packaging of products. Exquisite printing and packaging will arouse people's consumption impulse, thus improving product sales. What should we pay attention to when printing and packaging. The editor summarized some printing and packaging precautions for you, hoping to help you when you carry out printing and packaging in Shandong.

1、油墨的厚度及面积

1. Thickness and area of ink

印刷在承印物上的油墨厚薄，将直接影响到印刷产品的质量，有些印刷品上的图文面积过大，导致墨层很难与塑料薄膜粘合，就会造成脱层、起泡等现象。这原因主要是由于墨层改变了纸张多孔隙的表面特性，使纸张纤维毛细孔封闭，阻碍了粘合剂在纸张上的渗透和扩展。因此在印刷包装过程中要严格的控制印刷的墨量，一般控制范围在2-3μm。

The thickness of the ink printed on the substrate will directly affect the quality of the printed products. The large area of the image and text on some printed products will make it difficult for the ink layer to bond with the plastic film, which will cause delamination, blistering and other phenomena. This is mainly due to the fact that the ink layer changes the surface characteristics of the paper's pores, making the paper fiber pores closed, and hindering the penetration and expansion of the adhesive on the paper. Therefore, in the process of printing and packaging, the amount of ink to be printed should be strictly controlled, and the general control range is 2-3 μ m。

2、印刷包装的油墨

2. Ink for printing and packaging

印刷包装的覆膜产品，应采用快固着的亮光胶印油墨。因为快固着的亮光胶印油墨，它的连接料是由合成树脂，干性植物油，高沸点煤油等组成。这些合成树脂中的分子基团和交粘剂中的分子基团会相互扩展渗透，产生交联，形成物理化学的结合力，有利于覆膜。

The film-coated products for printing and packaging should use quick-setting bright offset printing ink. Because of the fast setting bright offset printing ink, its connecting material is composed of synthetic resin, dry vegetable oil, high boiling point kerosene, etc. The molecular groups in these synthetic resins and the molecular groups in the adhesives will expand and permeate each other, resulting in cross-linking, forming physical and chemical binding force, which is conducive to film covering.

3、印刷品的表面，里层干燥状况印刷品的表面墨层或里层干燥不良，对覆膜质量危害很大，会造成起泡，脱层等质量问题。影响印刷品的表面墨层干燥有很多因素，如油墨种类，干燥剂的用量，纸张的结构，车间环境的温湿度等等。

3. The surface and inner layer of the printed matter are dry. Poor drying of the surface ink layer or inner layer of the printed matter will do great harm to the quality of the film covering, and will cause quality problems such as blistering and delamination. There are many factors that affect the drying of the surface ink layer of printed matter, such as the type of ink, the amount of desiccant, the structure of paper, the temperature and humidity of the workshop environment, and so on.

因此我们在印刷时特别要注意墨层的干燥情况。大同印刷时严格控制好水墨平衡，注意油墨的乳化状况，控制好润版液的酸性值。同时控制好车间的温湿度。使印刷包装品的表面和里面真正做到干燥，使覆膜质量得到保证。

Therefore, we should pay special attention to the drying of the ink layer when printing. During Datong printing, strictly control the balance of ink and water, pay attention to the emulsification of ink, and control the acid value of fountain solution. Meanwhile, control the temperature and humidity of the workshop. Make the surface and inside of the printed packaging truly dry and ensure the quality of the film covering.

4、印刷喷粉的加放

4. Addition and placement of printing powder

为了适应多色机高速印刷，防止印刷中的纸张背面粘脏，包装胶印经常采用喷粉工艺来解决。所喷的粉，大多是谷类淀粉及天然的悬浮物质组成。这些粉颗粒粗，若印刷过程中喷粉过多，那么这些粉颗粒会浮在印刷品表面，覆膜时粘合剂不是每处都与墨层结合，严重的影响覆膜质量。因此在包装胶印印刷时要严格的控制喷粉量。在不粘脏的前提下，使用少的喷粉量。

In order to adapt to the high speed printing of multi-color machine and prevent the back of the paper from being dirty during printing, the packaging offset printing is often solved by the powder spraying process. The powder sprayed is mostly composed of cereal starch and natural suspended substances. These powder particles are coarse. If too much powder is sprayed during the printing process, these powder particles will float on the surface of the printed matter, and the adhesive will not combine with the ink layer at every place during the film covering, which will seriously affect the film covering quality. Therefore, the amount of powder spray should be strictly controlled when packaging offset printing. Use less powder spray on the premise that it is not sticky and dirty.
