Abstract

A finished flexo plate with printing dots and non-printing indicia. The printing dots have an elevation above the plate floor sufficient to transfer ink to a substrate in a printing step, whereas the non-printing indicia are configured for persistent readability relative to the plate floor but have a height relative to the plate floor insufficient to transfer ink to the substrate in the printing step. The non-printing indicia define a pattern of alphanumeric characters, non-text graphics, or a combination thereof, and are disposed on the plate floor in the form of areas of presence and absence of polymer defined by structures formed of microdots, each microdot having an elevation relative to the plate floor lower than a printing height.
