Innovation in Processing Used Palm Cooking Oil into Offset Printing Ink
Abstract:
The increasing demand for offset printing ink and the environmental impacts of petroleum-based materials have prompted a search for alternatives. This study aims to produce offset printing ink using used palm cooking oil as a substitute for petrochemical components. Previous studies have demonstrated the potential of used cooking oil for ink production. The methodology involved collecting and puryfiying oil, converting it into Fatty Acid Metyl Ester (FAME), formulating varnish, and producting ink. The results showed that ink made from used cooking oil (FAME-J) differed in optical density and CIE Lab* values compared to conventional ink. Specifically, FAME-J exhibited a lower optical density than Ink FAME-S and Ink-K, suggesting a thinner ink layer. The CIE Lab* analysis showed that Ink FAME-J had a slightly darker color and a lower lightness (L*) value compared to Ink FAME-S, while Ink-K exhibited a higher yellow component. Overall, used cooking oil demonstrates it’s viability as an alternative for producing offset printing ink, offering a sustainable option to reduce environmental impacts and support waste management efforts.
