| Abstract: | "Mineral oils are used in substantial quantities for the production of varnishes and inks due to their abundance and versatility. However, as part of the production process, some of mineral oil components are separated as waste material, whereupon they can mix with air, water, or soil and become potentially harmful to the environment. Almost all these waste materials are volatile organic compounds (VOCs), chemicals that can easily evaporate at room temperature and have toxic effect. Therefore, a novel green, mineral oil-free offset printing ink was produced using vegetable oil esters as bio-renewable raw materials. Accompanying varnishes were prepared with linseed oil, methyl oleate, octyl stearate, and four types of resin (A, B, C, and D). The application of these varnishes to magenta color offset ink was subsequently studied to screen out the best combination of resin and ester in terms of setting time. Meanwhile, dyeing force tests were conducted to evaluate the ink's printability, while rheological analysis was done via viscosity and flowability tests. The setting time of the magenta color offset ink made by varnish A was observed to be considerably shorter than that of the ink samples prepared using varnishes B, C, and D. Furthermore, varnish A proved to be a good alternative varnish for the production of yellow, cyan, and black color offset printing inks. Samples of these inks were printed on coated paper, and their printability was contrasted against that of vegetable oil-based (pure vegetable oil), mineral oil-based, and other mineral oil-free offset printing inks. Results determined that the varnishes produced with linseed oil, methyl oleate, and octyl stearate can replace mineral oil-based varnishes for the production of offset printing ink" |
