Characteristics of using water-based ink
Mar 31, 2022Water based ink is developing rapidly in the cause of global environmental protection, let's talk about the characteristics of using water-based ink:
1) slow drying effect on printing quality: general of water-based ink can be divided into two types, one is alcohol (> 10%), one is less do not contain alcohol or alcohol (< 10%).No matter what kind of products, in view of solvent-based inks, has been slow to dry ink.Slow dry ink in water, can cause great difficulty to dry ink, printing quality is easy to cause flow (water), after tack, unequal transfer problem.In general, in ink, the higher the content of ethanol, the more likely the problem little except (isopropyl alcohol).(4) covering rate influence to printing quality: due to reasons of water-based ink use resin, pigments, the color is often more transparent.This is the problem of insufficient cover rate.Adopt the method of enhancing the pigment content, can solve part of the problem, but also a large negative effects, such as high viscosity, thixotropy. Printing enterprise, therefore, cover rate high demand, if any, shall be made to the system of ink factory.
