[0002] After the wine is produced, it needs to be packaged in boxes. Decorative patterns are usually printed on the boxes, which need to be printed with box ink. Box ink printing uses various packaging materials as carriers to print decorative patterns on the boxes through ink to protect the goods, beautify the goods and convey information. At the same time, the packaging and printing industry is also transforming traditional technologies. For example, the commonly used solvent inks are replaced with water-based inks. Water-based inks are also called water-based inks. They are recognized as environmentally friendly printing inks by the world printing industry. Water-based inks dry more slowly than solvent inks, so there is also a need to develop green printing drying technology.
