Ink viscosity test

Ink viscosity plays a vital role in the field of packaging and printing ink. One specific type of ink that has gained attention in recent years is water based ink. Water based ink are known for their environmentally friendly properties and ability to produce vibrant colors. It is widely used in the packaging industry due to its low odor, fast drying time and easy cleanup. However, one aspect that requires careful attention is ink viscosity.Viscosity refers to the thickness or fluidity of a liquid. For water based ink, viscosity determines the ink's ability to evenly coat the plate and transfer it to the substrate. If the viscosity is too low, the ink will spread too quickly, resulting in poor color density and blurry prints. On the other hand, if the viscosity is too high, the ink may not spread enough, resulting in incomplete coverage and uneven printing.
