You're about to have some super sick apparel screen printed, so you have to ask yourself: which ink do you choose?
You may have heard that there are multiple kinds of inks to choose from when it comes to screen printing. Water-based and plastisol inks are the two popular print styles in the industry. Don’t worry. We’re here to help you understand that both inks have advantages and disadvantages and things that differ.
Real Thread has been screen printing using water-based inks since 2009. So we have a preferred method, but we understand that you may need to use a specific type of ink for a specific project.
Alright, let’s dive in! *cue a quiet woo-hoo in the background*
Critical Differences Between Water-Based and Plastisol Inks
Here is a breakdown of the fundamental differences between the two.
Water-based ink is, you guessed it, made with water—good 'ol H2O.
Plastisol ink is made with plastic. Who would've thought?
It seems simple, but things are more complex than that when you dive down and learn about them. They impact your screen prints differently. By the end of this article, we'll have described the two ink styles, and you'll have a clearer understanding of the differences between the two and know some advantages and disadvantages of each.
What is Water-based and discharge ink?
Water-based ink is a high-end ink commonly used in retail printing. In essence, water-based ink dyes the shirt's fabric and replaces the fabric color with the color of the ink rather than having the ink sit on top of the shirt. It's a mixture of water with dye or pigment. Water is the primary solvent to keep the pigment or dye in a liquid form.
For the print to cure, the water has to evaporate entirely. The ink sinks into the fabric, becoming part of the garment itself.
Longevity: Water-based prints last as long as the garment does, with no signs of cracking or peeling over time.
Brightness: The brightness level of a water-based print can range from very bright to somewhat faded, depending on the fabric of the shirt it's printed on. For example, on a 100% cotton t-shirt, your print will come off very bright and vibrant. But if you're to print on a cotton/polyester blend or tri-blend t-shirt, it might come out more toned down.
Feel: Water-based ink will leave your shirt with an incredibly soft and much more breathable print than any other ink type. Since the ink dyes the shirt's fabric, you cannot even feel the ink on the t-shirt.
Advantages of water-based inks
- Better for the environment
- Print is thinner/softer than plastisol inks.
- More breathable
- Inks soak into the fabric and become a part of the garment instead of sitting on top.
- Suitable for creating a "vintage look."
Disadvantages of water-based inks
- Influenced by the color of the shirt, making prints on dark garments tricky sometimes.
- More time-consuming to work with
- More expensive
Plastisol Ink
This is a plastic-based ink made for apparel. It is a cheaper ink that has long been the industry standard for screen printing.
Plastisol ink lays directly on top of the t-shirt fabric, covering the top with a layer of ink.
Plastisol is the standard, less-expensive ink for screen printing. It is made with plastic (polyvinyl chloride, better known as PVC.)
Plastisol has to reach 350°F for curing. This type of ink sits on top of the shirt; it doesn't soak in.
Longevity: Plastisol ink prints do eventually break down. After a handful of washes, plastisol prints tend to crack, peel, or flake off.
Brightness: Since the ink sits on top of the shirt, plastisol ink always produces a bright print.
Feel: Plastisol ink prints feel thick and heavy and allow less breathability than a print with water-based ink.
Advantages of plastisol inks
- Inexpensive
- Excellent opacity (can be used on dark garments with no issues)
- It doesn't require the use of running water
- Won't clog screens since this ink won't dry unless it's heated to 350°F.
Disadvantages of plastisol inks
- Less breathable
- Can bunch around seams
- Thick and heavy
- Can crack, peel, or flake off with long wear
The Real Thread preference: Water-Based Ink
We don’t use plastisol inks. We choose to print solely with water-based and discharge inks for a reason. The print is softer, more breathable, and more durable than its competitor, yielding a better overall t-shirt that people are going to love wearing again and again.
