Adhesive Labels can either darken or fade. The high-quality quantity of printed matter is measured as follows: the ink color of a batch of products should be consistent before and after the color, and the color should be bright, and at the same time, it should conform to the ink color hue and the darkness of the ink color of the sample. So what are the discoloration factors in the storage and use of Customized Adhesive Labels?

Most Self Adhesive Labels are stored for a long time, which is inevitably yellowish for several reasons.
