Matters needing attention in the printing process of paper packaging boxes
The packaging carton needs to go through a whole set of processes to complete. The printing process is immutable, but the same process, the finished product printed by people with good design skills can attract everyone's attention, and the finished product printed by people who do not know how to design is still very bad. Today, Yiwu Jialan Package Co, LTD. will introduce to you the problems that should be paid attention to in the printing process of paper packaging boxes.
Matters needing attention in the printing process of the packaging box:
1. Influence of paper characteristics on overprinting accuracy of printed matter
The finer the product, the higher the craftsmanship is required. For fine prints, the general allowable error must be within 0.05mm. In multi-color printing, there are many reasons for inaccurate overprinting, but the paper deformation caused by the change of water content in the printing process is an important factor.
2. The effect of paper characteristics on the reproduction of printed image tone
Ideal tone reproduction is the most important process to obtain high-quality printed images, and most of the poor prints are caused by tone reproduction problems.
3. The effect of paper characteristics on the gloss of the printed matter During the printing process, the ink film is transferred to the surface of the paper and fills the unevenness of the paper surface, making the surface of the printed matter quite smooth. The specular reflection of light on the surface of the ink film of the printed matter determines the gloss of the printed matter, and the surface of the ink film is closely related to the characteristics of the paper.
4. The influence of paper characteristics on the increase of dots
Dot gain affects reproduction hue changes more than any other variable. The amount of ink printed on the paper affects dot gain, and dot gain affects print contrast. When printing black-and-white or color-tone images, dot gain can alter image contrast and cause a loss of image detail and clarity. In multicolor printing, dot gain can result in loss of contrast, dark images, dot smearing, and dramatic color changes.
