As regarding the emission of volatile organic compounds, the comparison between the average baseline (in absence of printing) obtained, with those acquired during printing, without filtering system (WOF) (Figure 1), tests an increase of mean concentration of volatile organic compounds. By comparison the average concentration acquired without the use of this system (WOF) and with the use of the filtering system (WF), it shows that the amount of volatile organic compounds emitted is reduced. The results show that this filtering system is suitable for lowering of VOCs emissions.
