Sažetak
The efficiency of ink separation in the process of waste paper recycling depends among other things on the ink properties, kind of the substrate, the printing techniques and the printing conditions. Chemical deinking flotation does not efficiently remove water based flexographic inks, UV ink and varnish, ElectroInk and some toners from digital printed paper. The use of enzymes could be an alternative to chemical deinking. The investigations results about the chemical and enzymatic deinking process the prints from digital printing with liquid and powder toner have been presented in this paper. The used enzyme is the product of fermentation of the fungus Humicola insolens. It was used with the addition of non ionic tenside based on ethoxylated fatty acids. The investigation results show of brightness, improved dirt removal efficiency and the mechanical properties of handsheet are somewhat decreased.
