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.
