Packaging box printing occupies a large proportion in the printing industry and is an indispensable part of product packaging engineering. When printing packaging boxes, we should not only focus on appearance, but also consider its economy, environmental protection and other issues, and at the same time convey good information to consumers.

When designing a packaging box, we should start with trademarks, patterns, colors, plans, shapes, materials, etc. On the basis of considering the characteristics of the product, we should also follow some principles of brand design to coordinate and match various design elements to complement each other in order to obtain a good packaging box design plan. In fact, the important thing about packaging box design is whether the designer has a strong technique in image color processing and whether he can adjust the image color that satisfies the customer and exceeds the customer's expectations. When customers see the design draft, the first thing they see is whether the color of the image is good or not, whether the color is bright or not; if there is an original manuscript, they will compare it with the original manuscript to see if the color is similar; whether it is consistent with the color they want psychologically, etc.
Most packaging box printing designs are based on green, because green represents naturalness and environmental protection, so most people use green as the main color to make printed packaging boxes. And green has two components of yellow and blue. In green, the expansion of yellow and the contraction of blue are moderated, and the warmth of yellow and the coldness of blue are offset. This makes the character of green more peaceful and stable, and it is a soft, quiet, rich and beautiful color. When there is more yellow in green, its character tends to be lively, friendly and childish. When a small amount of black is added to green, its character tends to be solemn, sophisticated and mature. When a small amount of white is added to green, its character tends to be clean, refreshing and fresh.
In packaging box printing, there is often a saying that you look at the color from a distance and the flowers up close, look at the color first and then the flowers, and seven parts of the color and three parts of the flowers. These three sentences fully illustrate that it is very important to handle the color of the packaging product well. Therefore, we must be guided by the theory of packaging box printing color science, give full play to the methods of printing technology and the point of view of satisfying people's psychological requirements for color, combine the color characteristics of the packaging product, follow the color principles, and then process the color according to the printing process rules.
The above is an introduction on how to make the color more attractive in packaging box printing, I hope it will help everyone.
