How to investigate the effects of UV and ozone on ink fading?
We conducted some simple tests to investigate the effects of UV and ozone on ink fading of brother tn 660.First, the test method(1) ozone test: the test environment in the dark conditions, 30% to 40% humidity environment, the temperature at 20 degrees Celsius ~ 22 degrees Celsius.(2) UV test: We have chosen the most fluorescent lamps of UV light source, and it is a fluorescent lamp that can reach 150,000 lux in 24 hours. Test temperature is 70 degrees Celsius, so you can speed up the test.Process test of brother tn450 toner cartridge:1.The yellowing of the paper The preservation of the paper still affects the shelf life of the printed product. Another less noticeable phenomenon is the yellowing of the paper when it is exposed to ozone. The easiest yellow microporous paper. Often in the ink is not faded, some print media have faded, affecting people's judgments on ink fading. Paper retention rates are based on testing each paper for hindering yellowing by accelerating high temperature and high humidity conditions.2.Effect of Coating (Coating Solution) Another team's life expectancy is affected by the coating material. Ozone has been shown to have a large effect on some microporous coating media, which can easily destroy the coating properties. The phenomenon of exchange is the breakdown of the dielectric coating. Swelling-type media can stop the ozone effect, so the coating is not too obvious.Summarized as follows1, microporous photographic paper than the swelling photographic paper by the impact of UV and ozone significantly2, different structure of the dye configuration of the ink a greater impact on fading3, the coating solution will protect the impact, even if it is a will be fully protected4, ozone-sensitive microporous photographic paper exposed to the air easily yellowing5, the appropriate microporous media coating (including coating solution) can reduce the ozone effect, reduce the paper surface rupture6, dark (high density, density) than two-color printing print settings fadeFourth, the protection of printed matter affected by ozone measures and recommendations Placed in the glass frame can be a lot of UV and ozone to prevent the impact, or the printed product film protection. According to print the appropriate use of the file to select the appropriate ink cartridge media, to determine the length of the save file.
