Evaluating the color stability and display effect of gold screen printed end glass under different ambient lighting conditions is a key step to ensure its high-quality performance. High-end refrigerators and other home appliances use this decorative glass not only for aesthetics, but also to enhance user experience and brand image. Therefore, it is crucial for manufacturers and designers to fully understand its performance under various lighting conditions.First of all, simulating different lighting conditions in a laboratory environment is the basis for evaluating color stability and display effects. By using standard light source equipment such as D65 (simulated daylight), A (typical indoor incandescent light source), and TL84 or CWF (commercial fluorescent lamp), the test conditions can be precisely controlled. These light sources can represent various lighting conditions that consumers may encounter in their daily lives. For example, the D65 light source is used to simulate the visual effect under natural light outdoors, while the A light source is closer to the warm-toned light inside the home. Placing the sample under these light sources to observe and record its color changes can help discover potential color shift problems. At the same time, using a spectrophotometer to measure the sample reflectance spectrum data can obtain more objective and accurate color information, which is convenient for subsequent analysis and comparison.In addition to standard light source testing, actual scene testing cannot be ignored. Since natural light varies with time and weather, outdoor field testing can provide more realistic feedback. Selecting multiple time periods (morning, noon, evening) and different seasons for testing can fully understand the performance of gold screen printed end glass under natural light. In addition, setting up temporary display areas in typical indoor places such as shopping malls and offices and inviting ordinary consumers to participate in the evaluation is also an effective method. This method can not only obtain intuitive user feedback, but also help identify possible problems in specific environments.Color stability is not only affected by the light source, but also closely related to the characteristics of the material itself. The ink formula used in gold screen printing directly affects the color durability of the final product. High-quality inks should have good weather resistance and UV resistance, and will not fade even if exposed to strong light for a long time. To this end, the ink components need to be strictly screened and their performance verified by accelerated aging tests. For example, the QUV ultraviolet accelerated aging test chamber is used to simulate the aging process under long-term sunlight conditions to observe whether the samples have problems such as discoloration and peeling. After such pretreatment, the color parameters are measured again and compared with the initial values to evaluate the actual durability of the ink.In terms of display effect, in addition to the color itself, gloss and flatness are also important considerations. High-gloss surfaces can enhance the metallic texture and make gold appear brighter and more dazzling; however, excessive reflection may cause glare and affect the perception. Therefore, it is necessary to balance the relationship between gloss and practicality in the design stage. Using a gloss meter to measure the gloss value at different angles can help determine the best processing technology. In addition, flatness is directly related to image clarity and overall aesthetics. Any tiny unevenness will cause visual defects. With the help of precision testing instruments such as 3D profile scanners to check the surface microstructure, ensure that each piece of glass meets high standards.Finally, establishing a complete quality control system is essential to ensure product quality consistency. From raw material procurement to finished product delivery, every link requires detailed records and strict inspection processes. Enterprises should actively promote international quality certification systems such as ISO 9001, conduct internal audits and employee training on a regular basis, and continuously improve the quality awareness of all employees. At the same time, strengthening communication and collaboration with upstream and downstream suppliers and customers, and obtaining timely feedback information for improving production processes are also effective means to improve product quality.In summary, by testing in laboratory simulations and actual scenarios, optimizing ink formulations, paying attention to gloss and flatness, and implementing strict quality control measures, the color stability and display effects of gold screen printed end glass under different ambient lighting conditions can be fully evaluated. This not only helps meet consumers' demand for high-quality home appliances, but also provides a solid foundation for promoting the entire industry to a higher level.
