印刷包裝時總會有很多問題出現，所以就需要提前做好預防工作，以免給工作造成大的損失。今天我們就來說一說印刷包裝時的堵版故障的原因是什么。

　　There are always many problems in printing and packaging, so it is necessary to do preventive work in advance, so as not to cause big losses to the work. Today we say what is the cause of the blocking of printing and packaging.

　　由于某些因素（例如溶劑揮發過快），留在單元格中的墨水會部分干燥和凝固。當印版滾筒再次進入墨槽時，網穴中已固化的油墨難以完全溶解，油墨轉移率也隨之提高。累積效應是細胞被越來越淺地阻塞，直到發生阻塞失敗。這種堵塞故障與油墨種類、粘度、干燥速度、溶劑種類、印刷速度、印刷機結構等因素有關，其中比較常見的有以下兩種原因。

　　Due to certain factors, such as the rapid evaporation of the solvent, the ink left in the cell will partially dry and solidify. When the printing plate cylinder again into the ink tank, the net hole has been solidified ink is difficult to completely dissolve, ink transfer rate also increases. The cumulative effect is that the cells become shallower and shallower until the blockage fails. This blockage failure is related to the type of ink, viscosity, drying speed, solvent type, printing speed, printing machine structure and other factors, among which the following two reasons are more common.

　　油墨干燥速度。當油墨干燥過快時，一部分油墨在轉移到承印材料上之前會形成一層薄膜，而油墨薄膜的溶解性差必然導致油墨轉移不良，經過一段時間的積累，印刷盤子會被擋住。印刷車間的溫度和濕度會影響油墨的干燥速度。溫度過高或濕度過低都會加快油墨的干燥速度。如果墨水循環不良，墨水盒中的墨水很容易形成薄膜，從而導致堵塞。

　　Ink drying speed. When the ink dries too fast, part of the ink will form a film before transferring to the substrate, and the poor solubility of the ink film will inevitably lead to poor ink transfer, after a period of accumulation, the printing plate will be blocked. The temperature and humidity of the printing shop will affect the drying rate of ink. High temperature or low humidity will accelerate the drying speed of ink. If the ink circulates poorly, the ink in the cartridge can easily form a thin film, which can lead to blockage.

　　凹印設備問題。如果凹版印刷設備的各種機構設計存在問題，如滾筒直徑大、印版滾筒在墨槽中浸入較淺等，干燥時漏出的熱風盒子會直接吹到印版版面上，這會導致油墨在網版上在孔內干燥。

　　Gravure printing equipment problems. If there are problems in the design of various mechanisms of gravure printing equipment, such as large diameter of the drum, shallow immersion of the plate drum in the ink tank, etc., the hot air box leaked during drying will be directly blown to the plate layout, which will lead to ink drying in the hole on the screen.

　　山東印刷包裝認為雜質從外部環境混入墨水中。凹版印刷速度快，高速運轉時承印物容易產生靜電。在靜電吸附的作用下，可能會將周圍環境中的灰塵和從承印物上脫落的碎屑等雜質帶入油墨中。

　　Shandong printing and packaging that impurities from the external environment mixed with ink. Gravure printing is fast and the substrate is easy to produce static electricity when running at high speed. Under the action of electrostatic adsorption, it may bring the dust in the surrounding environment and impurities such as debris off the substrate into the ink. Plate cell blockage is an important reason.

　　為防止此類事故的發生，應在循環泵吸嘴處使用濾網除去油墨中的不溶性雜質。凹版印刷網線數較多時，油墨中較大的顆粒、不溶性物質和沉淀物會造成印版網孔堵塞。當油墨本身發生顏料分離、沉淀、重新凝聚等變化時，會產生不易重新溶解的物質，造成堵塞。

　　In order to prevent the occurrence of such accidents, the circulating pump suction nozzle should be used to remove insoluble impurities in the ink. Intaglio printing more network lines, ink in the larger particles, insoluble substances and sediments will cause plate mesh blockage. When the ink itself pigment separation, precipitation, re - coagulation and other changes, will not easily re - dissolved substances, resulting in blockage.
