Sažetak
Recycled fibres have become an important source in the paper production. In the deinking proces, the ink should first detach from the fibers, then ink and fibers separate from each other by flotation according to different surface properties. In this work the research results of the influence of the prints ageing on number and size of ink particles and the area they occupy on handsheet in different phases of the paper recycling process have been presented. Results are discussed in relation to prints from different printing techniques made with inks of different formulation. The research results confirm the prints ageing influence on the size and the number of ink particles on handsheet from different phases of the paper recycling process in the function of the printing technique and the ink composition in the framework of experimental conditions. Weaker recycling effectiveness of the aged offset prints with the ink with the increased part of the renewable raw material has been observed in relation to other samples, which is explained by the oxidative processes.
