# Water-based Ink Properties

When you order screen printing from Print Room NZ, we use **water-based inks** by default — and there’s a good reason why.

#### What is Water-Based Ink?

Water-based ink soaks into the fabric instead of sitting on top. It creates a soft, breathable print that feels like part of the garment — not a thick layer on top. It’s made using water as the main solvent, which means **no harsh chemicals, no plastic feel, and no cracked prints over time**.

#### What is Plastisol Ink?

Plastisol is a plastic-based ink that doesn’t soak into the fabric. Instead, it creates a thick coating on the surface. It’s easy for printers to use and lasts well — but it’s made with **PVC (polyvinyl chloride)** and requires chemical solvents to clean up. It’s still widely used in the industry, but it’s **less kind to the environment and harder on print staff**.
