In flexography (instrument…), a doctor blade is used to distribute the high viscosity ink onto the anilox role, which subsequently wets the pre-fabricated cliché bearing the pattern to be transferred. Afterwards, and in a role-based-process, the ink is being transferred from the cliché to the substrate. Parameters like anilox volume (which defines the amount of ink to be transferred), printing speed or role-to-role distance affect the printing quality.
