DIFFERENCES IN THE RECYCLING BEHAVIOUR OF PAPER PRINTED BY VARIOUS TECHNIQUES

The diversification of existing printing methods represents a great challenge for papermakers who utilize wastepaper in production processes. Prior to reuse, secondary fibres are subjected to some processing steps, for recovering their initial papermaking potential. Depending on the extent of recovering, the obtained fibrous material will be more or less recommended for the production of new paper products. The present paper approaches the deinking ability of offset, flexographic and digital prints in laboratory flotation deinking.
