隨著現(xiàn)在人們對(duì)紙張使用的重視，印刷紙本成為流行趨勢(shì)，選擇一家印刷公司是很重要的，今天我們來(lái)了解下在印刷紙本的過(guò)程中出現(xiàn)黑點(diǎn)的原因。

With people's attention to the use of paper, printing paper has become a popular trend. It is very important to choose a printing company. Today, let's understand the reasons for black spots in the process of printing paper.

印刷壓力的影響

Influence of printing pressure

1、印刷壓力：主要是油墨跟印刷紙張之間的磨合過(guò)程。

1. Printing pressure: mainly the running in process between ink and printing paper.

2、印刷壓力的控制并非易事：印刷壓力想要控制需要技術(shù)，想要做好需要從各個(gè)方面去入手。

2. It is not easy to control the printing pressure: it requires technology to control the printing pressure, and it needs to start from all aspects to do a good job.

油墨黏度對(duì)印刷的影響

Influence of ink viscosity on Printing

油墨是導(dǎo)致印刷紙本表面帶有黑點(diǎn)的主要原因

Ink is the main cause of black spots on the surface of printing paper

1、油墨黏度對(duì)印刷紙本的影響實(shí)驗(yàn)。

1. Experiment on the influence of ink viscosity on printing paper.

2、油墨的黏度合適是很關(guān)鍵的一個(gè)點(diǎn)。

2. The proper viscosity of ink is a key point.

對(duì)濕式疊印效果有很大影響，油墨的黏度大墨層表現(xiàn)出較大的內(nèi)聚力。

It has a great influence on the wet overprint effect. The viscosity of the ink is large, and the ink layer shows great cohesion.

①如果先印油墨黏度比后印油墨的黏度低后印油墨會(huì)依賴自身的內(nèi)聚力。

① If the viscosity of the first printing ink is lower than that of the second printing ink, the latter printing ink will rely on its own cohesion.

②先印的油墨粘走，產(chǎn)生“逆疊印”造成混色控制好黏度是比較重要的。

② The first printing ink sticks away, resulting in "reverse overprint" and color mixing. It is more important to control the viscosity well.

如果大家在印刷紙本之后發(fā)現(xiàn)上面有黑點(diǎn)的話，需要及時(shí)的跟濟(jì)南印刷廠家聯(lián)系作出修改，不然可能會(huì)影響紙本的正常使用。此外原紙表面出現(xiàn)斑點(diǎn)，一般都是由于原紙的問(wèn)題，因?yàn)樵堅(jiān)谏a(chǎn)過(guò)程中，里面殘?jiān)耸炝铣煞值奈镔|(zhì)，通過(guò)面紙加熱過(guò)程起到化學(xué)作業(yè)，細(xì)小的塑料顆粒融化后產(chǎn)生大小不一的黑色斑點(diǎn)，這種情況出現(xiàn)較多的是以再生紙為紙基的掛面紙。

If you find black spots on the paper after printing, you need to contact the Jinan printing factory in time to make modifications, otherwise it may affect the normal use of the paper. In addition, the appearance of spots on the surface of the base paper is generally due to the problem of the base paper, because in the production process of the base paper, there is a residue of clinker ingredients, which plays a chemical operation through the heating process of the surface paper. After the melting of fine plastic particles, black spots of different sizes are produced. This kind of situation occurs more often in the surface paper based on recycled paper.

以上就是今天為大家介紹的關(guān)于問(wèn)題以及注意事項(xiàng)的全部?jī)?nèi)容，希望對(duì)大家能有所幫助，想要了解更多內(nèi)容可以電話聯(lián)系我們或者關(guān)注我們的網(wǎng)站http://www.kenkeng.cn，我們的工作人員會(huì)及時(shí)與您取得聯(lián)系。
