The Role of Electrokinetic Sonic Amplitude on Gravure Cylinder Banding

In Gravure printing, the destruction of chrome plating in the form of banding is sporadic and destructive. While several factors are involved in this phenomenon, physico-chemical properties of the ink such as particle size, the Electrokinetic Sonic Amplitude (ESA) and conductivity seem to play a major role. Maximizing ESA offers a solution to this problem. While smaller particles are less abrasive, maximizing ESA corresponds to smaller particles with low conductivities in solvent based gravure inks.
