Water-Based vs Plastisol Ink: Which Screen Printing Ink Is Better?

Water-Based vs Plastisol Ink: The Complete Comparison

If you are ordering custom screen printed apparel, the type of ink used matters more than most people realize. The two dominant ink types — plastisol and water-based — produce noticeably different results in terms of look, feel, durability, and environmental impact.

At French Press Custom, we use both inks daily and recommend each for different applications. Here is an honest comparison.

Plastisol Ink: The Industry Workhorse

Plastisol is a PVC-based ink that has been the screen printing standard for decades. It sits on top of the fabric surface and cures when heated to approximately 320 degrees F.

How Plastisol Feels

Run your fingers across a plastisol print and you can feel it — a smooth, slightly raised layer on top of the fabric. It is noticeable but not uncomfortable. The hand feel ranges from light (thin ink deposit) to heavy (thick coverage on dark garments).

Plastisol Advantages

• Unmatched opacity — covers any garment color with rich, solid color
• Bulletproof durability — properly cured plastisol outlasts the garment
• Color accuracy — Pantone matching is precise and consistent
• Easy to work with — the most forgiving ink for printers
• Does not dry in the screen — can be left in the screen during breaks
• Works on any fabric — cotton, polyester, blends, canvas, anything
• Special effects available — puff, metallic, glow, high-density all use plastisol base

Plastisol Drawbacks

• Noticeable hand feel — you can feel the print
• Not breathable — the ink layer blocks airflow in the printed area
• PVC-based — contains polyvinyl chloride and phthalate plasticizers
• Requires solvent cleanup — cannot be washed with water
• Can crack if over-cured, under-cured, or subjected to extreme stretching

Environmental Concerns

Plastisol contains PVC and traditionally uses phthalate plasticizers (though phthalate-free formulations are now widely available). It requires petroleum-based solvents for cleanup. It is not biodegradable.

That said, plastisol waste can be recycled within the print shop, and properly managed plastisol printing has a relatively small environmental footprint compared to many manufacturing processes.

Water-Based Ink: The Soft Touch

Water-based ink absorbs into the fabric fibers rather than sitting on top. It uses water as the primary solvent and cures through heat and evaporation.

How Water-Based Feels

A water-based print feels like the fabric itself. On light-colored garments, you can barely tell where the print ends and the unprinted fabric begins. It is the definition of "soft hand."

Water-Based Advantages

• Ultra-soft hand feel — virtually invisible on the fabric
• Breathable — ink absorbs into fibers, maintaining fabric airflow
• Eco-friendlier — water-soluble, no PVC, no phthalates
• Easy cleanup — screens clean with water
• Fashion-preferred — the standard for high-end retail and fashion brands
• Beautiful on light garments — subtle, vintage, lived-in aesthetic

Water-Based Drawbacks

• Poor opacity on dark garments — transparent nature means it struggles on navy, black, etc.
• Dries in the screen — requires constant printing or screen flooding
• Harder to print — more technique-sensitive than plastisol
• Slower production — evaporation curing takes longer
• Less durable — fades faster than plastisol (though still lasts 30+ washes)
• Limited to cotton — best results on 100% cotton fabrics

Direct Comparison

| Factor | Plastisol | Water-Based | |--------|-----------|-------------| | Hand feel | Noticeable, smooth layer | Virtually invisible | | Opacity | Excellent on all colors | Best on light colors only | | Durability | 50+ washes | 30-40 washes | | Breathability | Blocked | Maintained | | Color vibrancy | 10/10 | 7/10 (light garments), 3/10 (dark) | | Environmental | PVC-based, solvent cleanup | Water-based, water cleanup | | Cost | Standard | +$0.50-1.00/color | | Best fabrics | Any | 100% cotton | | Production speed | Fast | Slower | | Printer skill needed | Moderate | Higher |

When to Choose Plastisol

Plastisol is the right call when:

• Printing on dark-colored garments (black, navy, maroon)
• You need maximum durability for workwear, uniforms, or daily-wear merch
• Your design requires exact Pantone color matching
• You want special effects (puff, metallic, glow-in-the-dark)
• Printing on polyester or poly-blends
• Large orders where production speed matters
• You need prints to last as long as possible

When to Choose Water-Based

Water-based is the right call when:

• Printing on white or light-colored cotton garments
• Soft hand feel is the top priority
• You are a fashion or retail brand where print feel affects perceived value
• You want a vintage, broken-in aesthetic from day one
• Environmental impact is a concern for your brand
• Printing athletic or performance wear where breathability matters
• Your customers are willing to pay a premium for a softer print

The Hybrid Approach

Many of our clients at French Press Custom use both inks strategically:

• Plastisol for their dark-garment designs and bold graphics
• Water-based for their light-garment fashion pieces
• Discharge (a water-based variant) for premium prints on dark cotton

This gives you the best of both worlds without compromising on any design.

Our Recommendation

For most custom apparel orders, plastisol is the practical choice — it works on everything, lasts forever, and is more cost-effective. But if you are building a premium brand and printing primarily on white or light cotton tees, water-based delivers a noticeably superior product that your customers will feel and appreciate.
