COMPARISON OF PRINT QUALITY ON PAPERS FROM INVASIVE ALIEN PLANTS SPECIES.

In nature there are more and more problems caused by invasive alien plant species. They not only threaten and displace native plants, but also cause economic damage. The aim of this study was to investigate and determine the percentage of weeking of prints on papers made from invasive alien plant species, i.e. Japanese knotweed and goldenrod. The same pattern was printed on both invasive alien plant species papers, Japanese knotweed and goldenrod, using two different printing techniques, i.e. inkjet and electrophotographic. We measured the percentage of the appearance of the week on both printing techniques. The highest percentage deviation of 9.42% was found on paper made of cellulose fibres obtained from goldenrod using the inkjet printing process, while the deviation from the ideal print using the electrophotographic printing process on the same paper was 2.02%. From the research results we can conclude that the electrophotographic printing technique is more suitable for printing on papers made from invasive alien plant species. [ABSTRACT FROM AUTHOR]
