The efforts on the de-inkability of flexo prints

Flexo and improved flexo prints were analysed as well as offset prints as reference sample for the alkaline and the near neutral de-inking process. The optical analysis (brightness, ERIC, L*a*, b*, specks) were made from pads of entire and hyperwashed pulps at each of laboratory steps. Water phase was analysed before flotation stage in terms of the surface tension, zeta-potential, nano-particle size, cationic demand and conductivity.
