Matsui Clear SWR (WS0574) | Water-Based Clear Mixing Base for Water-Repellent Fabrics — Nylon Windbreakers, Coated Polyester, DWR-Treated Outerwear — Mix with Neo Pigments for Custom Colors, Soft Hand, PVC-Free
Matsui
Matsui Clear SWR (WS0574) is a water-based transparent clear mixing base engineered specifically for printing on water-repellent fabrics — DWR-treated outerwear, nylon windbreakers, coated polyester athletic wear, and performance fabrics that cause standard water-based inks to bead up and fail. Clear SWR is the transparent base used to create custom colors on light and medium DWR-treated garments by mixing with Matsui Neo Pigments (up to 15%). It carries the same modified PU binder as White SWR for DWR adhesion, but is fully transparent — not an opaque white. ⚠️ Requires Fixer V (not Fixer WF-N) for wash fastness. Mesh 135/inch. PVC-free.
Price range: $49.99 through $899.99
Description
Matsui Clear SWR — Custom Colors on Performance Fabrics
Clear SWR is the transparent mixing base of the Matsui SWR system. Where White SWR provides an opaque white foundation, Clear SWR is fully transparent — it carries the SWR PU binder chemistry for DWR adhesion without the white pigment load. Mix up to 15% Neo Pigments into Clear SWR to create any custom color that prints directly on light or medium DWR-treated performance fabrics. The same fluoropolymer-penetrating chemistry that makes White SWR bond to DWR surfaces is built into Clear SWR — but without the white, so colors are transparent to the fabric color below.
Key Features
📊 Clear SWR vs. White SWR — When to Use Each
- Printing on light or medium DWR fabrics
- Mixing custom colors from Neo Pigments
- A transparent ink film is acceptable
- No white underbase is needed
- Printing on dark DWR fabrics
- Opacity is required
- Printing white as a standalone spot color
- Using as opaque tintable base for dark garments
Color Creation — Mixing Clear SWR with Neo Pigments
- Start with Clear SWR as your base.
- Add up to 15% Matsui Neo Pigments by weight. Mix thoroughly.
- Add Fixer V at 2–3%. Mix thoroughly.
- Add Retarder MG (1–5%) if needed for open time.
- Print a test on your specific DWR fabric. Fully cure. Wash test before production.
Because Clear SWR is transparent, colors are influenced by the fabric color underneath. On white or light fabrics, Neo Pigment colors in Clear SWR appear as vibrant spot colors. On colored fabrics, the clear base means colors mix visually with the fabric color below.
Recommended Additives
| Additive | Dosage | Purpose |
|---|---|---|
| Fixer V | 2–3% | ⚠️ REQUIRED for wash fastness on SWR inks. Fixer V is the correct fixer for PU binder inks — do NOT substitute Fixer WF-N. |
| Retarder MG | 1–5% | Extends open time — prevents ink drying in screen during longer runs. |
| Thickener B | 0.25–1% | Increases viscosity for halftone dot retention if needed. |

FREQUENTLY ASKED QUESTIONS
What fabrics is Clear 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 Clear SWR?
Yes — mix up to 15% Neo Pigments into Clear SWR for translucent custom Pantone®-matched colors on water-repellent fabrics. Use CMS Software for Pantone formulas. For more opaque custom colors, mix pigments into White SWR instead.
What is the difference between Clear SWR and White SWR?
Clear SWR is a translucent mixing base — the garment color shows through the print. Best for light water-repellent fabrics. White SWR is an opaque white — provides full coverage on dark water-repellent fabrics. Use White SWR when you need opacity, Clear SWR when you want translucency.
Can I print Clear SWR on dark water-repellent fabrics?
You can, but the colors will be muted and dark because the garment color shows through the translucent ink. For dark water-repellent fabrics, White SWR (as a standalone white or as a mixing white with Neo Pigments) will give much better results.
What mesh should I use?
135 mesh.
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%).
