摘 要:目的获得印刷品耐久性规律。方法通过耐黄变试验机,获得在一定温度和光照条件下,纸样和油墨的放置时间和色彩变化的数据,并利用二次多项式拟合方法,得出样品耐黄变的规律。结果试样纸张明度不随耐黄变时间的变化而变化,而试样油墨的明度随耐黄变时间的延长而呈现增加的趋势,与此同时,试样纸张、油墨和印刷试样的色度值b有增加趋势,符合二次函数变化规律。结论为分析印刷和包装产品的耐久性提供完整研究思路,并对合理选择承印材料提供理论依据。The work aims to obtain durability regularity of printed matter. Under certain temperature and illumination conditions, the data regarding storage time and color change of sample sheet and ink were obtained with yellowing resistance tester. Moreover, the regularity of sample resistance to yellowing was obtained in quadratic polynomial fitting method. The study found that the brightness of the sample sheet did not change with the change in anti-yellowing time, and the brightness of the ink sample showed an increasing trend with the anti-yellowing time prolonged. At the same time, the chromatic value b of the sample sheet, ink and printing sample had an increasing trend, which conformed to the changing rule of quadratic function. This study provides a complete research method for the analysis on the durability of printing and packaging products, and theoretical basis for the rational selection of the printing material.
