The Principles of Electrostatic Printing Assist

ENULEC ESA systems have become standard fixtures throughout the world, particularly when printing on paper, card and plastic film substrates, enabling a high quality of print to be maintained irrespective of factors such as impression roller characteristics, viscosity and machine speed.

The use of an Electrostatic Assist System (ESA) enables the cells in the cylinder of the gravure printing machine to be fully evacuated of ink and prevents the occurrence of missing dots (dot skips, snow flakes), which are as a result of ink not being transferred to the printing substrate, and is essential as a prerequisite for an optimum quality of print.
