THE EFFECTS OF NATURAL AND ARTIFICIAL AGING ON OPTICAL PROPERTIES OF LABORATORY PAPERS WITH TRITICALE PULP PRINTED USING THE UV INKJET TECHNIQUE
Published: 23 Sep 2021
Abstract: The fundamental raw material in the paper industry is cellulose. Cellulose fibers are traditionally obtained from wood and are used to produce a wide range of paper substrates. The recent significant increase in the consumption of wood resources is causing a global need for alternative non-wood cellulose fibers in paper production. The straw of various cereals is often used as a source of virgin cellulose fibers. Laboratory paper substrates made of recycled paper and triticale straw pulp are used in this research. This study aimed to explore the effects of artificial and natural aging processes on the optical deterioration of digitally printed laboratory substrates with variable triticale pulp content in recycled wood pulp. The goal was to assess the optical stability of UV inkjet cyan, magenta, yellow, and black prints after two aging process treatments. The optical stability was measured by observing the reflectance in the visible spectrum. The durability of UV inkjet prints and their reproduction quality play an important role in ensuring the accuracy of text and images in graphic products. The greatest optical stability after aging for a long period of time was observed for black prints on all test substrates.
