產(chǎn)品的銷量由眾多因素決定，比如產(chǎn)品質(zhì)量，產(chǎn)品，產(chǎn)品口碑等等，還有一項(xiàng)重要因素，那就是產(chǎn)品的印刷包裝。精美的印刷包裝會(huì)勾起人們的消費(fèi)沖動(dòng)，從而提升產(chǎn)品的銷量。那么在進(jìn)行印刷包裝的時(shí)候，我們應(yīng)該注意些什么。小編為大家總結(jié)了一些印刷包裝注意事項(xiàng)，希望在您進(jìn)行山東印刷包裝的時(shí)候能夠幫助到您。

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、油墨的厚度及面積

1. Thickness and area of ink

印刷在承印物上的油墨厚薄，將直接影響到印刷產(chǎn)品的質(zhì)量，有些印刷品上的圖文面積過大，導(dǎo)致墨層很難與塑料薄膜粘合，就會(huì)造成脫層、起泡等現(xiàn)象。這原因主要是由于墨層改變了紙張多孔隙的表面特性，使紙張纖維毛細(xì)孔封閉，阻礙了粘合劑在紙張上的滲透和擴(kuò)展。因此在印刷包裝過程中要嚴(yán)格的控制印刷的墨量，一般控制范圍在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、印刷包裝的油墨

2. Ink for printing and packaging

印刷包裝的覆膜產(chǎn)品，應(yīng)采用快固著的亮光膠印油墨。因?yàn)榭旃讨牧凉饽z印油墨，它的連接料是由合成樹脂，干性植物油，高沸點(diǎn)煤油等組成。這些合成樹脂中的分子基團(tuán)和交粘劑中的分子基團(tuán)會(huì)相互擴(kuò)展?jié)B透，產(chǎn)生交聯(lián)，形成物理化學(xué)的結(jié)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，里層干燥狀況印刷品的表面墨層或里層干燥不良，對覆膜質(zhì)量危害很大，會(huì)造成起泡，脫層等質(zhì)量問題。影響印刷品的表面墨層干燥有很多因素，如油墨種類，干燥劑的用量，紙張的結(jié)構(gòu)，車間環(huán)境的溫濕度等等。

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.

因此我們在印刷時(shí)特別要注意墨層的干燥情況。大同印刷時(shí)嚴(yán)格控制好水墨平衡，注意油墨的乳化狀況，控制好潤版液的酸性值。同時(shí)控制好車間的溫濕度。使印刷包裝品的表面和里面真正做到干燥，使覆膜質(zhì)量得到保證。

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、印刷噴粉的加放

4. Addition and placement of printing powder

為了適應(yīng)多色機(jī)高速印刷，防止印刷中的紙張背面粘臟，包裝膠印經(jīng)常采用噴粉工藝來。所噴的粉，大多是谷類淀粉及天然的懸浮物質(zhì)組成。這些粉顆粒粗，若印刷過程中噴粉過多，那么這些粉顆粒會(huì)浮在印刷品表面，覆膜時(shí)粘合劑不是每處都與墨層結(jié)合，嚴(yán)重的影響覆膜質(zhì)量。因此在包裝膠印印刷時(shí)要嚴(yán)格的控制噴粉量。在不粘臟的前提下，使用少的噴粉量。

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.
