Abstract
The characteristic of residual ink particles as well as the size distribution and
count of particles per unit area at different steps of a de-inking process are
helpful to understand and optimize the process of recycling.
The investigation results of the influence of the conditions in the Xerox
printing technique, as well as the natural ageing of prints on the count of
particles and ink area, are presented in the work. The influence of the multicolor
and de-saturated print obtained by the digital offset printing technique and
exposed to the accelerated ageing on the efficiency of the de-inking flotation is
observed.
The results are discussed, with the explanation of the influence of the ageing
process of the digital prints of different techniques and printing conditions on the
process of detaching and removal of the printing toner in recycling.
Keywords: digital prints, ageing, flotation deinking, count of particles, ink area.
1 Introduction
One of the factors which influence the de-inkability of waste paper is the process
of its ageing. Generally, the ageing could be in fact defined as a sum of all
irreversible physical and chemical processes that happen in the material during
time.
Deterioration in quality of an aged paper can manifest itself in chemical
permanence and the decrease in mechanical durability [1]. The permanence of
paper or prints depends on the chemical resistance of its components and of the
influence of external factors. The durability depends mainly on the physical and
