The method involves applying dyes (30, 31, 32, 33) through a digital, high-resolution printing process on a substrate (20). Individual pads (11) on a main body (10) of a device (1) are charged with a positive or negative electrostatic charge, the dyes are applied on the charged pads, and the surface (23) of the filter substrate is layered under the application of a force with the charged pads. USE - Especially for flat image display, e.g. active-matrix LCD. ADVANTAGE - Provides improved resolution of colour filter and improved image quality.
