Influence of the Composition of the Cyan Offset Ink on Deinked Fibress

The investigation results of deinkability of prints from sheet fed and web offset printing are presented in the article The model cyan inks of various composition in regard to the renewable raw materials are used. As printing surface the fine art papers and offset papers were yused. The measuring results of some optical values, the particle distribution and their size in the sample after deinking, show that the kind of oil used in ink preparation does not noticeably influence its removal in the deinking flotation. In the mean time, when in the flotation sample an additional parts of laser toner prints are added, the efficiency of the flotation process is somewhat lower.
