紙箱廠預(yù)印工藝對(duì)紙張有著特殊的要求。涂布白板紙的印刷面有很好的彩色表現(xiàn)力，但在通過(guò)瓦楞高溫烘道黏合過(guò)程中，涂料會(huì)有一定程度的變化，這將直接影響到紙箱表面彩色圖案的效果。因此涂布白板紙并不是瓦楞紙箱預(yù)印較為適用的紙張。掛漿白板紙雖然能夠滿足瓦楞高溫烘道黏合過(guò)程的要求，但其表面粗糙不平，容易使印刷圖案丟網(wǎng)點(diǎn)，不實(shí)、顯現(xiàn)力差，且該材料的油墨消耗量大，也不是理想的預(yù)印用紙。紙箱廠通過(guò)大量實(shí)踐證明，理想的預(yù)印用紙應(yīng)是白卡紙，它既能充分表現(xiàn)印刷圖案色彩，又能經(jīng)受瓦楞高溫烘道黏合過(guò)程的考驗(yàn)。
The pre printing process of carton factory has special requirements for paper. The printed surface of Coated Whiteboard has a good color expression, but the coating will change to a certain extent during the bonding process through the corrugated high-temperature baking channel, which will directly affect the effect of the color pattern on the surface of the carton. Therefore, coated white board paper is not a suitable paper for pre printing of corrugated boxes. Although the slurried white board paper can meet the requirements of the bonding process of the corrugated high-temperature baking path, its surface is rough and uneven, which is easy to cause the printing pattern to lose dots, which is not solid and poor in appearance. Moreover, the ink consumption of this material is large, and it is not an ideal preprint paper. Through a lot of practice, the carton factory has proved that the ideal pre printing paper should be white cardboard, which can not only fully display the color of the printed pattern, but also withstand the test of the high-temperature drying and bonding process of corrugated.
預(yù)印工藝對(duì)油墨的耐熱性和耐摩擦性有一定的特殊要求，預(yù)印生產(chǎn)的面紙?jiān)诩埾鋸S瓦楞紙板生產(chǎn)線上進(jìn)行壓平及在通過(guò)烘道工段的時(shí)候，要求使用的水性油墨應(yīng)該耐高溫性、耐磨性良好，否則彩面會(huì)掉墨、被拉花而成為殘次品。近年來(lái)，紙箱廠預(yù)印油墨以水性油墨為主，這是因?yàn)樗杂湍哂?、無(wú)味、綠色環(huán)保等優(yōu)點(diǎn)，紙箱發(fā)展的潮流。
The pre printing process has certain special requirements on the heat resistance and friction resistance of the ink. When the pre printed face paper is flattened on the corrugated board production line of the carton factory and passes through the drying section, it is required that the water-based ink used should have good high temperature resistance and wear resistance, otherwise the color surface will drop ink and be drawn and become defective. In recent years, the pre printing ink of carton factory is mainly water-based ink. This is because the water-based ink has the advantages of non-toxic, tasteless, green and environmental protection, and conforms to the trend of carton development.
預(yù)印油墨在國(guó)外已有比較成熟的經(jīng)驗(yàn)，國(guó)內(nèi)也有公司已研制出能滿足紙箱廠瓦楞紙板生產(chǎn)線使用的預(yù)印水油墨，成本與膠印油墨差不多。且水性油墨是經(jīng)過(guò)美國(guó)食品藥品監(jiān)督管理局認(rèn)可的油墨，紙箱廠用此油墨可印刷飲料箱、食品箱、藥品箱、出口包裝箱等上通行的綠色紙箱產(chǎn)品。
Preprint ink has relatively mature experience in foreign countries, and some domestic companies have developed preprint water ink that can meet the needs of corrugated board production line of carton factory, and the cost is similar to that of offset printing ink. The water-based ink is a non-toxic ink approved by the food and Drug Administration of the United States. The carton factory can print beverage boxes, food boxes, drug boxes, export packaging boxes and other internationally popular green carton products with this ink.
