 Kyrychok T. Yu., Hushcha O. V. The influence of intaglio printing on the durability characteristics of banknote paper — 2012. — № 2(36). — С. 4–10.
     The investigation of influence of intaglio printing on the strength characteristics of banknote paper was carried out. The investigation was based on a comparison of the changes of 1 hryvnia and 2 hryvnia banknotes. These denominations were selected because of their similar physical and functional properties. The only essential distinction is application of intaglio printing for 2 hryvnia banknote production and non-usage of intaglio printing for 1 hryvna banknote production.
     The experimental investigations showed a considerable worsening of tensile strength when deterioration of banknotes had increased. Though, the worsening of tensile strength because of deterioration is a little less for the2 hryvna banknotes. On the other hand, in case of new banknotes the tensile strength is higher for 1 hryvna. So, the strengthening effect of intaglio printing becomes apparent in banknotes circulation, so far as the intaglio printing hardens banknotes substrate by means of paper’s structure compaction.
