Water - Based Ink Does Not Fade, Viscosity Control Is Very Important

How can water-based ink not fade, in fact, the control of viscosity is the key, at the same time to control the viscosity of water-based ink determines the quality of printing products. If the viscosity of water-based ink is too large, it will affect the clarity of the printed text, or paste version and transfer of water-based ink ink too much affect the thickness of the ink film, resulting in the phenomenon of water-based ink fading. If the viscosity of water-based ink is too low, resulting in insufficient ink supply, insufficient transfer ink and printing quality, such as white, uniform strip phenomenon.

Although we know that water-based ink does not fade the key lies in the viscosity of water-based ink, but many users do not correctly understand the viscosity of water-based ink, always feel that when the viscosity of water-based ink is large, you can use a high proportion of dilution, you can reduce the printing cost, but ignore the quality of printed matter such as text is not clear, fading and other problems.

Water-based ink is composed of a certain proportion according to the actual characteristics and performance of printed matter. It is not allowed to add water to water-based ink and dilute water-based ink at will. In this way, the reasonable proportion of water-based ink resins, pigments, additives, amines and water and other components will lead to the destruction of the original characteristics of water-based ink. Therefore, arbitrarily change the viscosity of water-based ink, the quality of printed matter will be affected. Therefore, in order to make the printing work sustainable and stable operation, to ensure that the water-based ink does not appear fading phenomenon, it is necessary to control the viscosity of water-based ink.
