1. The water-based printing of corrugated boxes belongs to additive color printing. The color manuscript is made into a reverse image through electronic color separation, and then printed by a printing press, and the ink is transferred from the anilox roller of the printing press to the printing plate, and then the ink is transferred from the printing plate to the corrugated cardboard. The front image is obtained by color registration and overlapping, realizing the duplication of the original sample box and reproducing the quality of the original.

Red + blue = purple (cherry red, eggplant purple);

Blue + yellow = green (dark green, tender green).
