Chemical degradation of prints made on papers with wheat pulp
Nowadays, the production of paper and paper products has significantly focused on alternative nonwood raw materials. Croatia, as agricultural country, produces a large quantity of straw as a by-product of the crop farming. Therefore, straw is an interesting alternative raw material for cellulose fibres which could replace wood fibres sources. Today straw is used in animal food industry, biofuel industry, construction industry and as material in artistic expressions because of its numerous advantages. The potential utilization of that kind of crop residues in paper and packaging industry is of great importance considering a global deficiency of wood raw material. In this research, the wheat straw was converted into pulp and mixed with recycled wood fibres in order to produce alternative paper substrates. Laboratory formed papers were printed with black UV ink by digital technique. The quality of these prints was observed through the chemical stability to water, alcohol, acid and alkali. Evaluation of chemical degradation on prints was determined based on the spectrophotometric measurements (L*a*b* values) and Euclidean colour difference (ΔE00). Especially in the packaging industry, it is very important that prints have a good chemical stability to substances which are deposited inside the packaging.
