eInk and ePaper: Partners in Protecting Products

In the continuing fight against counterfeiting, eInk and ePaper technologies are emerging as vital tools, combining dynamic visual capabilities with robust anticounterfeiting features. While both technologies are distinct in their operational principles, in this article we will explore their joint ability to offer secure, flexible, and energy-efficient authentication solutions.

Understanding eInk

eInk technology is based on electrophoretic display (EPD) principles, where tiny, charged pigment particles are suspended in a fluid and manipulated through electric fields.

Depending on the polarity of the applied field, these particles move either toward or away from the surface, creating visible patterns or colours.

Traditional eInk displays have been monochromatic, leveraging black and white particles to generate highcontrast, paper-like visuals that are ideal for reading devices. However, advances such as multi-pigment particles have broadened the scope of applications.

A distinct advantage of eInk lies in its bi-stable nature – it requires no power to maintain an image once it is displayed.
