Packaging boxes are common in daily life, and there are many types of packaging boxes. Among them, paper packaging boxes are very environmentally friendly and are the choice of many people.
First：How should paper packaging boxes be moisture-proof?
1. Paper is very afraid of water. I believe everyone should know it. Once the carton is damp, it will not only affect the appearance of the box, but also seriously affect the structural strength of the box.
2. The warehouse or factory building where the gift box is stored must be well sealed, otherwise it is easy to get damp in the rainy season, foggy weather or areas with a large temperature difference between day and night.
3. There must be a gap between the gift box and the ground, which can be raised with wooden boards, and there must be a certain space for air circulation below, so as to avoid the influence of moisture on the ground.
4. If it is a manufacturer, you can choose to buy a dehumidifier, so you don't have to worry about getting wet anymore.
Second：what are the factors that affect the color of packaging and printing?
1. Whiteness and absorbency of paper: The whiteness of paper is the basis for bright printing colors. An ideal paper can reflect nearly all shades of light, while paper with gray, black, cyan, reddish or other cast colors will absorb part of the incident color light, which will affect the hue, lightness and saturation of the imprint, which is manifested as color fluctuation. difference. This is equivalent to adding some other inks to the ink to show the impurity of the ink, thus giving people a feeling of darkness, turbidity and color cast.
2. Ink transfer and rolling process: the ink fountain and ink roller are not clean when the color ink is applied, and other color inks are mixed, which will inevitably cause color cast and also cause the color to be dull. Therefore, when changing colors, be sure to clean the ink fountain, ink roller and water roller, especially when changing dark colors to light colors.
3. Excessive emulsification of ink and addition of additives: The traditional offset printing method mainly relies on the balance of water and ink to complete the printing process. According to the analysis of the ink transfer process, the emulsification of the ink is inevitable. However, over-emulsified ink will cause the color of the printed product to fade and become old, resulting in a reduction in color vividness.
