Sažetak
The main raw materials for papermaking are cellulose fibres. As there are fewer and fewer forests nowadays and therefore also fewer trees as raw materials for cellulose fibres, the production of paper and paper products has significantly focused on alternative non-wood raw materials. Since straw is available in large quantities as a by-product of the crop farming, it was selected as a potential paper fibre source. In this paper, the printing substrates were formed using straw pulp of wheat crop specie mixed with recycled wood pulp in different weight ratios. These innovative paper substrates were printed by digital technique (UV ink-jet) and reproduction quality of prints was observed through analysis of mechanical stability. The analysis of reproduction quality was performed on black and magenta full-tone prints. The aim of this work is to evaluate which ratio of wheat pulp in the innovative paper substrate will provide the highest rub stability. The evaluation of colour degradation was performed with spectrophotometer (L*a*b* values) and based on provided measurements the Euclidean colour difference (ΔE00) was determined. The digital printed innovative paper substrate could be used in production of the graphic products (books, magazines and newspapers), where the high degree of rub stability is very important.
