THE IMPACT OF PAPER MADE FROM RECYCLED AND NON-WOODY PLANTS ON THE EFFECT OF FLUORESCENT PRINTS

Fluorescent printing inks are often used for design elements in printing, signage, highlighted segments on packaging, and similar applications. In this research, commercially available papers made from recycled and non-woody fibers, such as hemp and cotton, will be used as substrates for printing with fluorescent inks. Paper printing substrate made entirely from virgin fibers will serve as a reference paper. The aim of this study is to determine the influence of paper made from recycled and non-woody plants on the effect of printed fluorescent inks. These paper printing substrates will be examined for their structural, surface, and optical properties, as well as screen-printed with fluorescent inks. The characteristic fluorescent effect of the printed ink will be evaluated using spectrophotometric method on all printing substrates. The difference between papers made from non-woody plants and recycled fibers compared to the reference paper made from virgin fibers will be determined, as well as their impact on the optical effect of fluorescent inks, printed elements, and line width. Additionally, a survey will be conducted to identify the most acceptable paper substrate for designs printed with fluorescent inks
