The Rub Resistance Assessment Of Offset UV Prints On Substrate Containing Triticale Pulp

In terms of volume, wood is the most available natural resource of cellulose fibres on earth. Although almost 2000 years ago the Chinese used other raw materials to make paper (bast, bark, hemp, rags and rice grass), today wood is still the most important raw material for pulp and paper production. As the forest area decreases daily, there are fewer trees as raw materials for cellulose fibres, the production of paper and paper products has significantly focused on the usability of alternative non-wood raw materials. The usage of these alternative cellulose fibres for paper production is the most cost-effective and environmental solution that aims to reduce the consumption of virgin wood pulp in paper production by replacing it with alternative plant biomass. The goal of this work was to assess the quality of offset prints on a substrate where wood fibres have been partially replaced by alternative fibres from triticale straw. For that purpose, laboratory-made printing substrate containing 30% triticale pulp was printed with UV low migration offset inks used for printing labels and non-food packaging. The assessment of the print quality on such substrates was based on the rub resistance according to the standard BS 3110:1959.
