Screen printing gets talked about as one process, but the actual ink used varies, and the differences aren't just technical โ€” they translate into a genuinely different feel on the finished garment, which is worth understanding if you're working with a local print shop and get asked to choose.

Plastisol: the traditional standard

Plastisol is the most common and traditional screen printing ink, known for vibrant, opaque color (it sits on top of the fabric rather than absorbing in) and strong durability over repeated washes. The tradeoff is feel โ€” plastisol prints, especially on larger or thicker designs, have a noticeable raised texture and can feel slightly stiff or "plasticky" against skin, particularly on cheaper or lower-quality plastisol formulations. Higher-quality, thinner plastisol formulations reduce this effect but don't eliminate it entirely.

Water-based ink: softer feel, different tradeoffs

Water-based ink absorbs into the fabric rather than sitting on top of it, producing a noticeably softer hand-feel โ€” often described as barely feeling like there's a print there at all, which some customers specifically seek out and mention positively in reviews. The tradeoff is that water-based ink generally produces less vibrant, slightly more muted color compared to plastisol, and can be somewhat less durable on certain fabric blends, particularly synthetic-heavy ones that don't absorb the water-based ink as readily as natural fibers do.

Discharge ink: a specific middle ground for dark fabrics

Discharge ink works by actually removing the fabric's original dye in the printed area before depositing new color, which produces a very soft, almost fully-absorbed feel similar to water-based ink, but specifically works better on dark garments where standard water-based ink can struggle to show up vibrantly. It requires specific dye-compatible fabric (not every fabric responds to the discharge process) and is a more specialized, sometimes pricier option.

What this means if you're choosing

If a specific hand-feel is important to your niche's expectations (a soft, premium-feeling shirt for a fashion-forward audience, for instance), it's worth specifically asking a local print shop which ink type they're using by default, rather than assuming โ€” POD platforms using DTG or DTF sidestep this specific choice entirely, since neither uses traditional screen printing ink, but it's a genuinely relevant question the moment you're working with a screen printing shop directly.
