紙箱廠預印工藝對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力，但在通過瓦楞高溫烘道黏合過程中，涂料會有一定程度的變化，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程的要求，但其表面粗糙不平，容易使印刷圖案丟網點，不實、顯現力差，且該材料的油墨消耗量大，也不是理想的預印用紙。紙箱廠通過大量實踐證明，理想的預印用紙應是白卡紙，它既能充分表現印刷圖案色彩，又能經受瓦楞高溫烘道黏合過程的考驗。
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.
預印工藝對油墨的耐熱性和耐摩擦性有一定的特殊要求，預印生產的面紙在紙箱廠瓦楞紙板生產線上進行壓平及在通過烘道工段的時候，要求使用的水性油墨應該耐高溫性、耐磨性良好，否則彩面會掉墨、被拉花而成為殘次品。近年來，紙箱廠預印油墨以水性油墨為主，這是因為水性油墨具有、無味、綠色環保等優點，紙箱發展的潮流。
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.
預印油墨在國外已有比較成熟的經驗，國內也有公司已研制出能滿足紙箱廠瓦楞紙板生產線使用的預印水油墨，成本與膠印油墨差不多。且水性油墨是經過美國食品藥品監督管理局認可的油墨，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.
