Evaluation of plant‐based oils for production of offset printing ink

Abstract

The oils and solvents are the main components of the printing ink, and the chemical composition of the ink could be harmful or toxic to human health and the environment. Therefore, there is an increasing demand to develop inks containing green, biobased, sustainable, and renewable raw materials instead of petrochemical substances. In this study, flaxseed oil (FO), pomegranate seed oil, plum kernel oil (PKO), and grape seed oil (GSO) were selected to produce offset printing inks. Pinus pinaster (P. pinaster) resin was also used in the formulation of inks to examine the effects of natural resin on ink together with vegetable oils. The phenolic content was analyzed for the resin and oils to figure out their potential antioxidant and bioactive characteristics. Optical and rheological tests were applied to evaluate the printability of the inks. L*a*b*, ΔE, density, and gloss tests were performed for optical evaluation. The viscosity, tack, and rub resistance tests were applied to perform rheological analysis. The biobased, environmental friendly, and self-drying (cold set) offset printing inks were obtained using natural pine resin and three different plant-based oils FO, PKO, and GSO. The printability analysis of the inks figured out the potential usage of plant-based oils in the offset printing ink formulation.

Boosting plant oil yields: the role of genetic engineering in industrial applications

“…However, vegetable oils have been increasingly used as raw ingredients in resin manufacturing in recent years. Several studies have explored the use of different types of essential oils to create eco-friendly printing inks, which are particularly important in the production of ink, varnish, and paint (Chen et al, 2021a; Hayta et al, 2022). The shift towards using vegetable oils in inks not only addresses environmental concerns but also promotes the sustainability of raw materials in the printing industry.…”

Mengubah Sampah Menjadi Harta Karun: Inovasi Daur Ulang yang Menguntungkan Lingkungan dan Ekonomi (Studi Literature)

“…Pemusnahan limbah ini secara efektif dan teratur diperlukan untuk melindungi lingkungan dan kesehatan karyawan. Beberapa limbah di daur ulang dan digunakan kembali dalam industri percetakan, tetapi dalam beberapa kasus, daur ulang tidak mungkin dilakukan, dan limbah ini harus dihilangkan tanpa membahayakan kesehatan manusia dan lingkungan (Hayta & Oktav, 2019).…”
