Effect of Ink Viscosity on Fixing Fastness of Imprinting

The viscosity of the ink refers to the size of the ink resisting the splitting force of the ink film. The transfer condition of the ink in the printing process is related to the viscosity of the ink. Since the ink is a fluid substance, it has fluid properties. The viscosity of the ink used for the screen printing has not only the plastic viscosity but also the structural viscosity.

Insufficient adhesion of the ink itself causes the ink film to be firmly fixed. It is best to replace other types of inks for printing. Different printing methods, substrates, inks, inks, diluting agents, and inks that are compatible with their printing materials and suitability are selected. Agents, brighteners, desiccants, and other auxiliary materials, the amount can not be too large, improper use of ink thinner will also appear not firmly fixed ink film, in the choice of dilution solvent to consider the nature of ink to avoid ink and substrate Inadequate bonding occurs.
