In flexo printing, anilox rollers and photopolymer plates are used to apply the color to the material being printed, just as in offset coating with a chamber doctor blade system. Continual mixing of the ink during the printing process ensures a homogeneous distribution of the effect pigments. The proper anilox rollers and suitable polymer plates must be selected to ensure an undisturbed process and the best possible results. Top photopolymer plates include Nyloflex® FAH and Nyloflex® ART from Flint Group and Cyrel® DEC from DuPont.
The printing ink and its viscosity, as well as the cell geometry of the anilox rollers, must be adjusted to the effect pigment used – please see the table below.
