Sažetak
Paper as a printing substrate upon ageing varies in the physical, chemical and optical properties. Paper composition strongly influence on its permanence during aging. The aim of this study is to determine the optical changes in the paper substrates by artificial ageing. The research was carried out with laboratory paper substrates made by mixing isolated barley fibres with the recycled wood fibres in a weight ratio 10:90, 20:80 and 30:70. Cellulose fibres in form of the pulp were isolated from barley straw in a process known as chemical pulping. Laboratory paper substrates made only from recycled wood fibres was used as a control paper. All paper substrates were artificially aged using standard techniques of accelerated ageing: dry-heat and treatment with a xenon arc lamp. The changes in the optical stability of paper substrates were analysed after accelerated ageing and presented in form of relative reflectance spectra differences, brightness differences and Euclidean differences.
