Factors Affecting Curability of UV Ink
some kinds and colors of materials have the property of absorbing ultraviolet rays, the curing of these materials will slow down. In addition, the same type of material will have different curing properties due to different grades.

UV Ink Printing
for UV ink, yellow and red ultraviolet rays are generally easy to penetrate, while blue and black ultraviolet rays, especially black ultraviolet rays, are difficult to penetrate. Therefore, if the national language increases the printing concentration in order to improve the printing effect, it will result in poor hardening, ink erasing, poor adhesion, and even reverse sticking cylinder. Special attention is paid to the printing concentration of black ink in UV printing.

UV ink
UV ink has the property that its viscosity changes sharply with the change of air temperature. This viscosity change will have a great impact on the printing adaptability and the thickness of the printing film. Generally, when the ink temperature decreases, the viscosity increases and the film thickness becomes thicker. If the viscosity of the ink changes too high and the permeability of the screen deteriorates, the printing film thickness will result in foaming and more porosity. Therefore, ple

UV ink light
UV ink is the most widely used ink for printing iron in the world. It has strong surface adhesion to non-porous agents, iron sheets, aluminum sheets and plastic sheets, and is often used for printing such articles.
Its biggest disadvantage is its poor chemical resistance, and many alkaline chemicals can attack it. Because the molecular weight is low, the polymerization time is longer. In other words, that is, the drying is relatively slow, but the curing speed is extremely fast with a single-linmore >
