Matsui Pearl Binder 301 | Water-Based Pearlescent Iridescent Ink for Soft Luxury Screen Printing on Cotton & Blends — Tintable with Neo Pigments for Custom Pearl Colors
Matsui
Matsui Pearl Binder 301 (WS0508) is a water-based special-effect pearlescent ink that produces a luminous, iridescent finish — the subtle, color-shifting light play of pearl, mother-of-pearl, and opalescent surfaces. Unlike metallic shimmer inks that reflect a single metallic tone, Pearl Binder 301 creates a softer, nuanced light-reactive effect that shifts subtly as the viewing angle changes. Use straight from the container for a standalone pearl finish, OR tint with up to 2% Neo Pigments for pearlescent pink, blue, lavender, mint, and more. Also works as an iridescent overcoat over flat printed designs. Prints through mesh up to 110/inch.
Price range: $34.99 through $99.99
Description
Pearl. Iridescent. Understated Luxury.
Matsui Pearl Binder 301 is where screen printing whispers luxury instead of shouting metallic. The pearlescent iridescent finish shifts subtly with the viewing angle, catching light in a way that changes as you move — like the inside of a seashell, not the surface of a chrome bumper.
Pearl Binder 301 creates a luminous, iridescent finish with soft, diffused, color-shifting light play that changes with the viewing angle. This is fundamentally different from metallic shimmer — Pearl is subtle and elegant, not bold and reflective.
Use straight from the container for a stunning white pearl / opalescent finish. Add up to 2% Neo Pigments for tinted pearlescent effects: pearlescent pink, blue, lavender, mint, champagne. The pigment shifts the tone while the pearl effect remains dominant.
Pearl Binder 301 is limited to 2% Neo Pigments — much lower than other bases. This is because pearlescent particles are delicate and translucent — higher pigment concentrations overwhelm the pearl effect. A trace amount of pigment shifts the tone; more destroys it.
Print Pearl Binder 301 over a fully cured standard Matsui color design. The translucent pearl layer adds a shimmering, opalescent quality to the color underneath — giving flat prints a luxurious, color-shifting overcoat.
Prints through mesh up to 110/inch. Lower mesh deposits more pearlescent particles for a stronger pearl effect.
Water-based formulation for a dramatically softer feel than pearlescent plastisol inks. The pearl finish integrates with the fabric rather than sitting on it.

Pearl vs Shimmer — Choosing the Right Special Effect
Pearl creates a soft, diffused, iridescent effect that shifts subtly with angle. The mood is luxury, sophistication, bridal, feminine, and refined. “I want it to glow softly.” Pearl is the answer.
Gold Shimmer 620 and Silver Shimmer 620 create bright, direct metallic reflections — one bold metallic tone that catches light powerfully. “I want it to shine metallic.” Shimmer is the answer.
Bridal boutique merchandise, feminine fashion prints, luxury cosmetics packaging merch, high-end event apparel, and any application where the design communicates sophistication through restraint rather than bold metallic flash.
Best Use Cases
Pearl effects for bridal boutique merchandise, bridesmaid gifts, formal wear decoration, and wedding-related apparel where elegance and restraint are the aesthetic.
High-end retail apparel, luxury brand merchandise, and fashion collaborations where the pearl finish communicates premium quality through subtle visual sophistication.
Pearlescent pink for feminine branding, pearl lavender for romantic aesthetics, pearl blue for luxury men’s apparel — tinted pearl creates nuanced color-effect combinations.
Print Pearl Binder over an existing flat color design to add a shimmering, opalescent quality. The color underneath appears to shift and glow as the viewing angle changes.
Pro Tips & Critical Notes
This is a strict limit for Pearl Binder 301. Above 2%, the pigment overwhelms the pearlescent particles and the pearl effect disappears. A trace amount (1-2%) shifts the tone while preserving the effect.
Like other particle-based inks, pearlescent particles can clog mesh when ink dries. Add Retarder MG at 1-5% to extend open time, especially on long runs.
Pearl Binder 301 is translucent. On light garments the effect is soft and luminous. On dark garments, print over a white underbase for best visibility.
When using Pearl Binder as an overcoat over another Matsui ink, ensure the base layer is fully cured before overprinting. Test the layering effect on your specific garment and inks before committing to production.

FREQUENTLY ASKED QUESTIONS
What is the difference between Pearl Binder 301 and the Shimmer 620 inks?
They create completely different effects. Pearl Binder 301 is pearlescent and iridescent, with soft, diffused, color-shifting light play that changes with viewing angle. Gold Shimmer 620 and Silver Shimmer 620 are metallic, with bright, direct, single-tone reflections. Pearl whispers luxury. Shimmer shouts metallic. Both are beautiful, just in different ways.
Can I tint Pearl Binder 301 with Neo Pigments?
Yes, but only up to 2%. Pearl is a delicate effect. Higher pigment percentages overwhelm the pearlescent particles and reduce the iridescence. A trace amount of Neo Pigment can shift the tone toward pink pearl, blue pearl, or lavender pearl while preserving the color-shifting pearl effect.
Why is the tinting maximum only 2% instead of 5% or 15%?
Pearlescent particles are translucent light-refracting structures that create iridescence by splitting light. Too much pigment coats and obscures those particles, turning the effect from iridescent pearl into a tinted ink with some leftover sheen. At 2% or below, the pigment adds tonal direction while the pearl effect remains dominant.
What mesh count should I use?
Up to 110/inch (43/cm). Lower mesh deposits more pearlescent particles for a more visible effect. Do not exceed 110 mesh, because finer openings can filter out the pearlescent particles.
Can I print Pearl Binder 301 on dark garments?
Yes, but print a white underbase first, flash it, then print Pearl Binder 301 on top. The white gives the pearl a reflective foundation so it stays visible against the dark fabric. Without a white underbase, the effect can get lost into the garment color.
Can I use Pearl Binder 301 as an iridescent overcoat over a colored design?
Yes. Print your standard Matsui color design, flash it, then print Pearl Binder 301 over the top. The translucent pearl layer adds an iridescent overcoat to the color underneath, giving it a shimmering, opalescent quality.
What additives should I use with Pearl Binder 301?
For most jobs, use Quick Additive at 6–9%. For individual control, use Retarder MG at 1–5%, which is especially important with particle-based inks to help prevent screen clogging, plus Fixer WF-N at 1–5% and Softener MG at 1–4%. Browse all Matsui additives here.
Is Pearl Binder 301 softer than pearlescent plastisol?
Dramatically softer. Pearl Binder 301 is water-based, so the pearlescent particles integrate with the fabric instead of sitting on top as a rigid PVC layer. The hand feel difference is immediately noticeable.
Does the pearlescent effect wash off?
With proper curing at 320°F (160°C), the pearl effect is durable. Add Fixer WF-N at 1–5% to crosslink the binder and help lock the pearlescent particles in place for maximum wash durability.
Can Pearl Binder 301 be dry cleaned and ironed?
Yes. Prints made with Pearl Binder 301 are safe for both dry cleaning and ironing.
Is Pearl Binder 301 visible under all lighting?
The pearlescent effect is most visible under direct, angled light such as sunlight, spotlights, or directional indoor lighting. Under flat, diffused fluorescent lighting, the effect is more subtle. It helps to consider the end-use lighting environment when designing with pearl.
Is Pearl Binder 301 safe for children’s clothing?
Yes. It is OEKO-TEX® compliant, CPSIA compliant, and HR4040 compliant. It is also PVC-free and environmentally safe.
