Flexography (or flexo) is a printing technique from the relief printing family, similar to letterpress printing. The printing plate is made of soft photopolymers shaped as printing plates, sleeves, or compact cylinders. Thin ink is applied to the elevated printing elements utilising the grid anilox roller whilst the amount of the ink is indicated by the depth and density of the grid on the roller. This technique is generally used in high-speed rotary printing and it allows for printing on a great variety of substrate materials.
Flexo is used at SPWS chiefly in processes involving special types of inks where the demand for a higher deposit of ink is greater in order to achieve the optimum effects as compared to the regular offset printing techniques.
