Sažetak
On the base of the experimental design the influence of the accelerated ageing process of prints in the controlled conditions and the determined time intervals (10, 20, 30 days) on the mechanism of ink detaching in the deinking process has been investigated in this article. The investigations comprise the prints of the offset technique with the conventional and ecologically more suitable ink and the printing substrates of different compositions. The investigation results show that the greatest influence of the accelerated ageing of prints is in the period of 10 days on handsheet brightness made from the fibers after the recycling process. The influence of the ink composition and the printing substrate on handsheet brightness from the different phases of the recycling process in the function of the distribution of the size and the number of the residual ink particles on the handsheet has been discussed.
