Description

The White Ink That Sticks to Water-Repellent Fabrics

Standard water-based inks fail on water-repellent fabrics. The DWR (durable water repellent) coating that makes a nylon windbreaker shed rain also makes it shed ink — the ink beads up, will not bond, and peels or cracks after curing. Matsui White SWR solves this problem. It is specifically formulated to adhere to slick, water-repellent treated surfaces with excellent adhesion, durability, and wash fastness.

White SWR provides good opacity on dark water-repellent fabrics — use it as a standalone opaque white, as a white underbase for layered color prints, or as a mixing white with up to 15% Neo Pigments to create custom colors on water-repellent garments.

What Fabrics Is SWR Designed For?

The SWR Series is specifically engineered for fabrics that have been treated with a water-repellent (DWR) coating — the kind of slick, coated surface that causes standard water-based inks to bead up, crack, or peel off. Common water-repellent fabrics include:

Nylon windbreakers and rain jackets. Coated nylon shell jackets, pullover windbreakers, and lightweight outerwear.

Polyester performance outerwear. Water-repellent polyester soft shells, track jackets, and warm-up gear.

DWR-treated athletic wear. Outdoor performance garments with durable water repellent (DWR) finishes.

Coated nylon bags and accessories. Drawstring bags, tote bags, and backpack panels made from coated nylon.

Water-resistant promotional items. Branded umbrellas, ponchos, and packable rain gear.

⚠️ SWR is NOT needed for standard cotton, cotton-poly blends, or untreated polyester. For those fabrics, use standard Matsui bases like 301C Clear, Stretch Clear, or EasyPrint Clear. SWR is specifically for water-repellent treated surfaces where standard inks will not adhere properly.

White SWR vs. Clear SWR — Two Products, Two Roles

SWR Product Finish Best For
White SWR (THIS PRODUCT) Opaque white Standalone white on darks. White underbase for color prints. Mixing white with Neo Pigments for opaque custom colors.
Clear SWR Clear / translucent Clear mixing base with Neo Pigments for translucent custom colors on light water-repellent fabrics. Tone-on-tone effects.

When to choose White SWR: Use White SWR when printing on dark water-repellent fabrics (dark nylon, black windbreakers, dark polyester shells) — the opaque white provides the coverage and contrast needed. Also use as a mixing white when you need opaque custom colors with Neo Pigments on water-repellent substrates.

Custom Colors with Neo Pigments

Mix up to 15% Matsui Neo Pigments into White SWR to create custom Pantone®-matched colors with opaque coverage on water-repellent fabrics. Use Matsui CMS (Color Matching Software) to look up the formula for your target Pantone code and base combination.

Recommended Additives

Additive Dosage Production Problem It Solves
Retarder MG 1-5% Ink drying in the screen — extends open time.
Fixer WF-N 1-5% Improved wash fastness.
Softener MG 1-4% Better fabric penetration and softer hand feel.
Thickener B 0.25-1% Ink too thin — thickens viscosity.
RV Additive 1-3% Ink too thick — reduces viscosity for smoother flow.
Fixer L 1-3% Low-curing fabrics or electric dryers.
Quick Additive 6-9% All-in-one — Retarder MG + Fixer WF-N + Softener MG. One additive, three benefits. Recommended for most jobs.

The SWR Series Family

SWR Product Role
Clear SWR (WS0574) Clear mixing base. Mix with Neo Pigments for custom colors on water-repellent fabrics.
White SWR (WS0575) — THIS PRODUCT Opaque white. Good opacity on dark water-repellent fabrics. Also a mixing white with Neo Pigments.

FREQUENTLY ASKED QUESTIONS

What fabrics is White SWR designed for?

Water-repellent (DWR) treated fabrics — nylon windbreakers, coated polyester outerwear, water-resistant jackets, DWR-treated performance garments, and coated nylon bags/accessories. If the fabric is designed to repel water, you need SWR.

Can I use standard water-based ink on nylon windbreakers instead?

No — standard water-based inks (301C, Stretch, EasyPrint, Infinity, Alpha) are designed for cotton, cotton-poly, and untreated polyester. On water-repellent coated surfaces, standard inks will not bond properly — they will bead up, crack, or peel. SWR is specifically formulated to adhere to these slick, coated surfaces.

Can I mix custom colors with White SWR?

Yes — mix up to 15% Neo Pigments into White SWR for opaque custom Pantone®-matched colors on water-repellent fabrics. Use CMS Software for Pantone formulas.

What is the difference between White SWR and Clear SWR?

White SWR is an opaque white — use for dark water-repellent fabrics, white underbases, and opaque custom colors. Clear SWR is a clear/translucent mixing base — use for translucent custom colors on light water-repellent fabrics and tone-on-tone effects.

What mesh should I use?

135 mesh.

Do I need a blocker for polyester dye migration?

On dark polyester with dye migration risk, use Kombat Blocker under the White SWR to prevent dye bleed-through. Always test before production — wait 48 hours after curing to check for dye migration.

How long does shipping take?

⚠️ This product drop ships from Matsui out of Gardena, California and may take 2-3 extra days to ship beyond standard shipping times.

What additives should I use?

Use Quick Additive (6-9%) for an all-in-one solution. Or individual additives: Retarder MG (1-5%), Fixer WF-N (1-5%), Softener MG (1-4%).
