Recycling possibilities of digital impressionss

The efficiency of defibring and flotation on Xerox and Xeikon impression as well as the influence of toner retention on some optical and mechanical properties of handsheets were investigated. The investigation results show that the difference in flotation efficiency is mainly proportional to the number of toner fibres aggregates. It was noticed that there was important influence on optical properties and strechability of the handsheets of toner particles after flotation as well as smaller influence on tear and burst of samples.
