In the process of commercial transactions of cosmetics, the quality evaluation of cosmetic packaging boxes is particularly important. The complexity of color printing technology is well known. The production of a cosmetic packaging box requires more than a dozen processes, and printing is the most important step. It determines the quality of the entire packaging box. Therefore, strict control measures need to be established during the printing process to avoid production quality issues and prevent color deviation in printing.
To prevent color deviation in printing, two main factors, paper and ink, need to be addressed to understand the causes of color deviation and how to solve them.

Paper factor: When purchasing paper, it is important to pay attention to differences in whiteness, smoothness, and ink absorption ability within the same batch of products, as these can lead to color deviation in printed products. If the paper has equal reflectance for each spectral component of white light but the overall reflectance is not high, the paper will appear gray. This will reduce the saturation of the printed colors and make the image appear darker, as if a layer of gray has been added to each color. When the paper selectively absorbs different wavelengths of light, it exhibits a color cast, which can cause severe color deviation in the printed product. For example, if the paper has a yellowish tint, the resulting image color will also appear yellowish. Therefore, before printing on packaging boxes, it is necessary to check the paper for any noticeable color deviation. Different manufacturers may produce papers of different colors and smoothness. It's best to use paper from the same batch with similar whiteness, smoothness, and ink absorption ability to avoid color deviation in the printed packaging boxes.

Ink factor: Inks produced by different manufacturers, even if they have the same color when compared, can result in color variations when printed. Different types, grades, and purposes of inks from different manufacturers can cause color deviation in printed items. When blending inks, it is advisable to avoid mixing inks with significantly different densities, as this can lead to ink separation, where the top layer of ink tends to be biased toward the ink with a lower density, while the bottom layer tends to be biased toward the ink with a higher density. For printing visually appealing and highly layered prints, especially when using offset printing, inks with strong color intensity are preferred to achieve clear reproductions of color tones. However, for printing solid products where overall ink coverage is high, the coloring power of the ink can be slightly reduced. If the transparency or coverage of the ink does not meet the requirements, appropriate adjustments can be made. When the transparency of the ink is insufficient, a suitable amount of extender or transparent oil can be added for adjustment. If the coverage of the ink is insufficient, inks with stronger coverage or adjustments to the ink color can be used to compensate for the deficiency and achieve the desired color standard in printing.


Therefore, it is essential for printing personnel to pay attention to these two factors when printing cosmetic packaging boxes to avoid color deviation, which may result in losses for the company and unnecessary workload for themselves.
