纸箱厂预印工艺对纸张有着特殊的要求。涂布白板纸的印刷面有很好的彩色表现力，但在通过瓦楞高温烘道黏合过程中，涂料会有一定程度的变化，这将直接影响到纸箱表面彩色图案的效果。因此涂布白板纸并不是瓦楞纸箱预印较为适用的纸张。挂浆白板纸虽然能够满足瓦楞高温烘道黏合过程的要求，但其表面粗糙不平，容易使印刷图案丢网点，不实、显现力差，且该材料的油墨消耗量大，也不是理想的预印用纸。纸箱厂通过大量实践证明，理想的预印用纸应是白卡纸，它既能充分表现印刷图案色彩，又能经受瓦楞高温烘道黏合过程的考验。
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.
预印工艺对油墨的耐热性和耐摩擦性有一定的特殊要求，预印生产的面纸在纸箱厂瓦楞纸板生产线上进行压平及在通过烘道工段的时候，要求使用的水性油墨应该耐高温性、耐磨性良好，否则彩面会掉墨、被拉花而成为残次品。近年来，纸箱厂预印油墨以水性油墨为主，这是因为水性油墨具有、无味、绿色环保等优点，纸箱发展的潮流。
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.
预印油墨在国外已有比较成熟的经验，国内也有公司已研制出能满足纸箱厂瓦楞纸板生产线使用的预印水油墨，成本与胶印油墨差不多。且水性油墨是经过美国食品药品监督管理局认可的油墨，纸箱厂用此油墨可印刷饮料箱、食品箱、药品箱、出口包装箱等上通行的绿色纸箱产品。
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.
