In today’s world, as we strive to make more eco-friendly choices, even the ink we use for printing matters. You might have come across the terms ‘eco solvent’ and ‘sublimation ink’, but what do these mean, and how do they affect our environment? This article provides a comprehensive breakdown of eco solvent vs sublimation ink, discussing their key features, similarities, and differences. Whether you’re a printing enthusiast, a business owner, or just someone interested in reducing your carbon footprint, understanding these two types of inks can guide you towards greener printing solutions.

What is eco solvent ink and what is sublimation ink?

Let’s start with eco solvent ink. This type of ink is known for its minimal environmental impact. Eco solvent inks are not based on any toxic solvents. Instead, they use bio-degradable solvent produced from ether extracts taken from refined mineral oil. In a nutshell, these inks are kinder to our environment. They are low-odor and don’t release any harmful volatile organic compounds into the air. Plus, their colors are bright, and they adhere well to various print materials, making them a versatile choice!

On the other hand, sublimation ink is a unique type of ink used for dye-sublimation printing. What’s that, you ask? It’s a process that uses heat to transfer dye onto materials like plastic, card, paper, or even fabric. The key feature of sublimation ink is its ability to convert from a solid to a gas without passing through the liquid stage. When heat is applied, the ink transforms into a gas and fuses with the material, creating a bright, durable, and wear-resistant finish.

Key differences between eco solvent and sublimation ink
