Sažetak
By processing the digital offset prints in the different chemical agents the impurities particles are detached from the printing substrate. The greatest detaching and impurities removal was obtained in alkaline solution of hydrogen peroxide. Flotation deinking is not a successful process for removing the particles of polymer ElectroInk from the cellulose suspension of Indigo print. Effectiveness of deinking flotation is increased with pre-processing of Indigo prints in alkaline solution of hydrogen peroxide. By soaking and washing Indigo print a considerable amount of impurities particles are removed. A part of residual impurities in pre-processed samples is removed by flotation. Removal of impurities by pre-processing in handsheets before and after flotation decreases the number of ElectroInk particles and the share of ashes, and improves their mechanical properties.
