The picture of the photo inkjet is beautiful and the color saturation is good and beautiful. It is the choice of advertisers to do print advertising, especially in recent years, with the price of domestic photo machine greatly reduced, the price of the photo has also decreased, so more and more choose to print this kind of print advertising, especially some Large-scale shopping malls and supermarkets are the main consumers of photo advertising. However, since the photo ink used in the photo machine is water-based dye ink, it is not waterproof and UV-resistant. If it is placed outdoors, it will quickly fade. Even if it is placed indoors, the fading will become dim and no longer bright due to the illumination of the light. Is there a way to effectively increase the shelf life of the photo to prevent the photo ink from fading quickly? The answer is yes.
Fading is the dye that encounters some redox species. When the ink is applied to the coated medium, it is coated with a gelatinous film. If the coating or film contains oxidizing substances, it will fade. Occurs, for example, when our hands are inadvertently stained with ink, it is very difficult to wash off. It will be washed off immediately after disinfection with 84. This is the reason why this kind of fading generally has the following characteristics：
1. Light-colored or neutral-colored images feel very fast and sometimes only a few hours.
2. This kind of picture will fade quickly even if it is placed in a dark place.
3, the color of the spray painting surface fades to a certain extent is not faded (indicating a part of the reaction), the specific situation will be slightly different. At present, the general material coating in the domestic market is basically through, and the lamp is inferior. The fading of the film is also happening from time to time. We can understand this through some practical tests. There is also the fading of the photo spray painting surface. The reason for the water is because the film is passed before the photo ink on the screen is completely dried. Linyi character advertisement printing
