The relationship between glossiness and color of printed matter and the measurement methods

In the field of printing, the quality assessment of printed materials is a complex and crucial step, among which glossiness and color are two important characteristics. There is a close relationship between them, and an accurate measurement method is crucial for ensuring the quality of printed matter.

The glossiness of printed matter has a significant impact on the presentation of color. Higher gloss can enhance the saturation and contrast of colors, making them more vivid, bright and lively. This is because a high-gloss surface can better reflect light, making the color purity higher and the color more vivid. On the contrary, a low-gloss surface scatters light, causing the color to appear darker, softer, with relatively lower saturation and contrast.

Glossiness and color are interrelated in printed matter and jointly affect the appearance quality of the printed matter. High-gloss printed materials have a smoother surface, which can reflect more light and make the colors more vivid and bright. On the contrary, printed materials with low gloss have a rougher surface, a weaker ability to reflect light, and their colors appear rather dull.

Specifically, the influence of glossiness on the color of printed matter is mainly reflected in the following aspects:
1. Enhance color saturation: The surface of high-gloss printed matter can reduce the white light reflected from the first layer surface, thereby enhancing the color saturation and making the colors more vivid.
 

2. Affecting color lightness: Glossiness also affects the lightness of the colors in printed matter. The higher the glossiness, the less white light is reflected from the first layer surface, and the higher the lightness of the color. Conversely, the lower the glossiness, the more white light is reflected from the first layer surface, and the lower the lightness of the color.
 

3. Impact on color visual effect: Glossiness also affects people's visual perception of the color of printed matter. High-gloss printed materials have a smoother surface, which can create a better visual texture and make the colors more attractive.
 

To accurately measure the glossiness and color of printed matter and ensure product quality, professional measuring instruments and scientific measurement methods must be adopted. The DG60 series gloss meter from CHNSpec, with its compact and lightweight design, efficient measurement speed and precise data output, has become a key tool for quality control in the printing industry. TheCHNSpec DG60 series gloss meter can quickly and accurately obtain the gloss data of printed paper. Whether it is a high-gloss, semi-gloss or matte surface, precise measurement results can be obtained. With the help of real-time data feedback, printing manufacturers can promptly adjust process parameters to ensure that each batch of printed materials meets the predetermined gloss standards.

For the measurement of glossiness, before the measurement, it is necessary to ensure that the instrument has been calibrated and the measurement environment is stable, avoiding interference from external light and temperature. Place the measuring probe of the gloss meter vertically on the surface of the printed matter and read the displayed gloss value. To obtain accurate and reliable results, it is usually necessary to measure at multiple locations and calculate the average value.

The measurement of color usually employs a spectrophotometer. TheCHNSpec DS-700 series spectrophotometer can accurately measure the appearance color of printed materials and achieve digital management of the appearance of printed materials.

In conclusion, the glossiness and color of printed matter are interrelated and jointly affect the quality and visual effect of the printed matter. Through scientific and reasonable measurement methods, these two key factors can be effectively controlled and evaluated, providing high-quality products for the printing industry.
