What is the reason for the small white spots on the anti-counterfeiting self-adhesive label

Nowadays, label paper is used a lot, and anti-counterfeiting self-adhesive label paper is also in great demand, especially in some card companies, with the high-efficiency production of modern machinery and equipment, sometimes there will be a little white spot. Once small white spots appear on the anti-counterfeiting label, it will endanger the quality of the product. Many manufacturers do not know the cause of the white spots on the labeler, so they cannot eliminate this kind of hazard. Let's briefly talk about the reasons for the white spots on the anti-counterfeiting self-adhesive labels.

First of all, the uneven surface of the raw material of the anti-counterfeiting label will cause white spots on the labeler. Under a certain working pressure, the same amount of ink and the same viscosity. Because the leveling of ink printing is not good, it will eventually cause small white spots.

When the coating of the material is not good, it will also cause small white spots on the label, because the coating of the material has poor compressive strength, and the printing viscosity of the ink is very high. Ink printing will stick the coating of the raw material away from the surface of the raw material, and promote the surface of the final printed matter. A little bit of regularity.

These above are the reasons for the white spots on the anti-counterfeiting self-adhesive labels, so two issues should be paid attention to when producing and printing.
