Influence of the printing techniques on the characteristic of the recycled fibers

The article presents the investigation results of the multicolour recycled prints obtained by the digital printing with powder toner as well as the digital printing with liquid toner and by the conventional offset printing process with inks based on mineral oil. The results show smaller efficiency of flotation for the prints from digital printing techniques and smaller handsheet brightness in relation to offset printing. The possible influences ofthe printing techniques, ink composition and print drying process on efficiency of deinking flotation and characteristics of recycled fiber are discussed in the article.
