Can you use Water-Based Ink on Polyurethane?

Feasibility of Water-Based Ink Printing on Polyurethane

Water-based ink printing on polyurethane is a feasible technique, but it comes with its own set of challenges. Polyurethane, a type of plastic, is a non-porous material, which means it does not absorb ink like paper or fabric. Therefore, the ink must be able to adhere to the surface of the material. Water-based inks, while environmentally friendly and easy to work with, may not adhere as well to polyurethane as other types of inks.

Is Water-Based Ink Printing on Polyurethane Advised?

While it is possible to use water-based ink on polyurethane, it is not generally advised. The main reason for this is the difficulty in achieving a durable, long-lasting print. Water-based inks tend to dry quickly, which can lead to poor adhesion and a print that may easily scratch or peel off. Additionally, the fast drying time can lead to clogging in the printer, causing further issues.

Better Printing Techniques for Polyurethane

For printing on polyurethane, solvent-based inks or UV-curable inks are often recommended. Solvent-based inks contain chemicals that enable the ink to bond more effectively with the polyurethane, resulting in a more durable print. UV-curable inks, on the other hand, are cured or dried using UV light, which also results in a strong, durable print. Both of these types of inks are more resistant to scratching and peeling than water-based inks, making them a better choice for printing on polyurethane.
