Water-Based Screen Printing Ink: A Sustainable and Vibrant Choice

Screen printing is one of the most popular and versatile methods for applying designs to various materials, especially fabrics like T-shirts, hoodies, and bags. When it comes to choosing the right ink for screen printing, water-based inks are gaining increasing popularity for their eco-friendly properties and high-quality finish. In this article, we’ll explore the advantages of water-based screen printing ink, how it differs from other types of inks, and why it’s a great option for both beginner and professional printers.

What is Water-Based Screen Printing Ink?

Water-based screen printing ink is a type of ink that uses water as the primary solvent to dissolve and carry the pigments. Unlike plastisol inks, which rely on chemicals and need to be cured with heat, water-based inks are activated by water and can be used to create vibrant, soft prints that bond with the fabric instead of sitting on top of it.

This ink type has become a go-to choice for screen printers looking for a more environmentally friendly option. Because water is the main carrier, the ink contains fewer harmful chemicals and is less likely to cause environmental pollution compared to solvent-based inks.

Advantages of Water-Based Screen Printing Ink

Eco-Friendly and SustainableOne of the main reasons screen printers opt for water-based inks is because they are much more eco-friendly than their plastisol counterparts. Water-based inks contain no PVCs (polyvinyl chloride), which are harmful to both the environment and the printer. They also release fewer volatile organic compounds (VOCs), which can be harmful to air quality and human health. If sustainability is important to your business or personal printing needs, water-based ink is the way to go.
Soft and Comfortable PrintsWater-based ink creates a softer print compared to plastisol ink. Because it soaks into the fabric rather than sitting on top, the result is a more comfortable, breathable garment. This makes water-based ink ideal for apparel, especially for soft and vintage-style prints. Water-based prints also feel more natural against the skin, which is an important factor for many customers.
Vibrant and Bright ColorsDespite being water-based, this type of ink produces vibrant, rich colors that pop on light and dark fabrics. The pigments used in water-based inks are finely ground, which helps achieve more precise and detailed designs. Furthermore, these inks can offer a high level of opacity, allowing for better color coverage and vivid prints, even on dark garments.
Long-Lasting ResultsWater-based screen printing inks are known for their durability. When properly cured, the prints are long-lasting and resistant to fading, cracking, or peeling, even after multiple washes. This makes them a great option for high-quality, custom apparel that will stand the test of time.
VersatilityWater-based inks are not only used for fabric printing, but they can also be applied to paper, wood, and other substrates, making them a versatile choice for different printing projects. This adaptability allows printers to experiment and expand their product offerings.
Easy CleanupSince water-based inks use water as the main solvent, cleanup is much easier than with plastisol inks. You only need water to clean your screens, squeegees, and other equipment, which means fewer harsh chemicals in your workspace and a more streamlined cleanup process.

How Water-Based Screen Printing Ink Differs from Other Inks

Water-Based Ink vs. Plastisol InkPlastisol ink is the most commonly used ink in screen printing, but it requires heat to cure properly, and it sits on top of the fabric. While plastisol inks provide a thicker, more opaque print, they lack the soft hand-feel that water-based inks provide. Water-based ink, on the other hand, soaks into the fabric, offering a softer finish and a more eco-friendly process. However, water-based inks are more prone to drying in the screen during printing, which can be a challenge for beginners, and they require more careful curing to ensure durability.
Water-Based Ink vs. Solvent-Based InkSolvent-based inks are less commonly used in screen printing due to their harmful environmental and health effects. These inks rely on chemical solvents, which can release VOCs that are detrimental to the environment. Water-based inks, in contrast, offer a safer, greener option without sacrificing print quality or durability.

Tips for Using Water-Based Screen Printing Ink

Proper Curing: While water-based ink doesn’t require the intense heat needed by plastisol inks, it still requires proper curing to ensure durability. Make sure to cure your prints at around 320°F (160°C), depending on the ink manufacturer’s instructions. This ensures the ink bonds well with the fabric.
Use the Right Mesh Count: Water-based inks are more fluid than plastisol inks, so you’ll need to use a finer mesh count (usually around 160 to 230 mesh) to avoid excessive ink deposits. A higher mesh count allows for finer details and better print results.
Print with Care: Because water-based inks dry quickly, it’s important to keep your screens moist during printing, especially in warm environments. Using a spray bottle to lightly mist the screen with water can help keep the ink flowing smoothly and avoid drying in the screen.
Test for Opacity: Water-based inks are often less opaque than plastisol, so if you're printing on dark fabrics, you may need to use an underbase or special white ink to ensure the design stands out.
