Comparative Analysis Of Print Ink Density Of Conventional And Soya-Based Ink On Paper Board Using Offset Printing Process

Abstract

The shift towards environmentally sustainable materials in the printing industry has led to increased interest in alternative ink formulations, such as soya-based inks, which offer reduced environmental impact compared to conventional petroleum-based inks. This study presents a comparative analysis of print ink density achieved using conventional and soya-based inks on paperboard substrates through the offset printing process. Ink density plays a critical role in determining print quality, influencing factors such as colour strength, image sharpness, and overall visual consistency. In this research, controlled printing trials were conducted using standard offset press conditions to ensure uniformity. Both ink types were applied to identical paperboard substrates, and ink density measurements were taken using a densitometer at designated control points. The aim is to evaluate the printing performance and visual strength of soya-based ink in relation to conventional ink, contributing to the understanding of its viability in commercial printing applications. The study offers insights into the print behaviour of sustainable inks and supports the industry's movement toward eco-friendly practices without compromising essential print quality parameters.
