Abstract

With introducing the environmentally acceptable solutions in printing systems, the effect of corrosion of machine elements becomes more aggressive, unknown and unpredictable, which partly or completely disables long-term exploitation and amortization of printing machines. In this paper, the influence of conventional and ecological fountain solution concentrates was analysed during 31 months, as well as the influence of dissolved compounds from the paper surface on the corrosion of carbon steel. The rate of corrosion in the observed systems was quantified with gravimetric method, while it was qualified with FT-IR spectroscopic method. Transmission FT-IR spectra were recorded for the starting solutions and corrosion products. It was shown that the compounds from the paper surface, dissolved during the printing have the most significant influence on the course and dynamics of corrosion in the printing systems.
