Sažetak
Texts and images in graphic industry are made of small dots, thus the printed dot fidelity greatly affects image reproduction quality as one of its most important elements. However, reproduction quality does not only depend on printing techniques and inks used in the printing process but also on paper substrates. As paper industry is faced with a global deficiency of wood raw materials, alternative sources of virgin cellulose fibres play an important role in the paper production. For that purpose, this research was performed on paper substrates produced by mixing fibres isolated from triticale straw and recycled wood fibres in different weight rations. In order to isolate cellulose fibres, the triticale straw was exposed to alkaline treatment using two methods. The printability of handsheets, laboratory paper substrates made of fibres isolated from triticale straw, was analysed by way of classifying dot fidelity. The handsheets were printed using UV-curable inkjet printer. Dot fidelity was observed by analysing images comparing seven different dot dimensions in relation to their dot area and dot shape descriptors (roundness, aspect ratio and solidity). Determined dot characteristics on six different paper substrates with triticale fibres were compared against a control paper substrate made only of recycled fibres.
