Smart utilization of triticale straw in the printing industry

Nowadays, the production of paper and paper products has significantly focused on alternative non-wood 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 fibers which could replace wood fibers 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 industry is of great importance considering a global deficiency of wood raw material. In this research, the fibers isolated from triticale straw were mixed with recycled wood fibers in order to produce alternative paper substrates. The possibility of using those produced paper substrates in the printing industry was examined based on the reproduction quality of the line. High quality line reproduction is extremely important feature for reading printed texts and barcodes. The line reproduction quality, based on three line attributes: blurriness, raggedness and width, was analyzed.
