Matsui Glow Yellow ECGG Pigment | Super-Concentrated Fluorescent Yellow Pigment for Neon Screen Printing — Mix with Any Matsui Water-Based, Discharge, or Special Effects Base for Electric Fluorescent Yellow Prints
Matsui
Matsui Glow Yellow ECGG is a super-concentrated fluorescent yellow pigment from the Matsui Glow Pigment system — one of 8 fluorescent/neon pigments designed for creating vivid, eye-catching neon colors in water-based screen printing. ⚠️ THESE ARE FLUORESCENT PIGMENTS — THEY DO NOT GLOW IN THE DARK. “Glow” refers to the intense fluorescent vibrancy under normal and UV lighting, not phosphorescent glow-in-the-dark properties. ⚠️ PIGMENT ONLY — must be mixed with a Matsui base before printing. By itself, it will NOT adhere to fabric. Glow Pigments can be mixed at up to 20% concentration into Matsui bases — higher than Neo Pigments (10-15%) — for maximum fluorescent intensity. Compatible with ALL Matsui printing bases and can also be blended with Neo Pigments for custom fluorescent-tinted shades. Use the free Matsui CMS Color Matching Software for Pantone® formulas. Prints through very high mesh counts (up to 305+). Cure at 320°F (160°C) for 2.5-3 minutes. OEKO-TEX® Standard 100 certified. CPSIA and HR4040 compliant. PVC-free, phthalate-free, heavy metal-free, formaldehyde-free. Exceptionally soft hand feel.
Price range: $39.99 through $149.99
Description
⚠️ IMPORTANT: Fluorescent — NOT Glow-in-the-Dark
Matsui Glow Pigments DO NOT glow in the dark. The name “Glow” refers to the intense fluorescent vibrancy these pigments produce under normal daylight and UV/blacklight conditions — not phosphorescent glow-in-the-dark properties. These are neon/fluorescent pigments that create electric, high-visibility colors that appear to “glow” with vibrancy compared to standard pigments. Under UV blacklight, fluorescent prints will appear even more vivid. But when the lights go out, the print does not emit light.
Glow Yellow ECGG — Super-Concentrated Fluorescent Yellow
Glow Yellow ECGG is not an ink. It is a super-concentrated fluorescent yellow pigment that must be mixed into a Matsui base to create printable ink.
Where standard Neo Yellow M3G produces a solid, opaque yellow, Glow Yellow ECGG produces an electric, high-visibility fluorescent yellow that demands attention. The fluorescent effect is most dramatic on white and light garments where the base fabric reflects light back through the fluorescent pigment. On dark garments, print over a white underbase for maximum neon impact.
Mix Glow Yellow ECGG into a discharge base for fluorescent yellow on dark cotton. Mix it into an acrylic clear base for electric neon yellow on light garments. Blend it with Neo Pigments to create fluorescent-tinted custom shades — ideal for high-visibility safety prints, event merchandise, and attention-grabbing designs.
⚠️ Pigment Only — Must Be Mixed with a Base
Glow Yellow ECGG will NOT adhere to fabric by itself. It must be mixed into a Matsui base before printing. The base acts as the binder that carries the pigment to the fabric surface and locks it in during curing. Without a base, the pigment will wash off.
Mixing ratio: Up to 20% pigment by weight into the base. Glow Pigments allow a higher concentration than Neo Pigments (which max at 10-15%). Higher pigment loads create more intense fluorescent effect. Start at 15% and increase to 20% for maximum neon intensity.
Pantone® color matching: Use the free Matsui CMS Color Matching Software for Pantone® formulas that include Glow Pigments.
Blending with Neo Pigments: YES — Glow Pigments can be mixed with Neo Pigments. Add a small percentage of Glow Yellow to a standard Neo color formula to shift it toward a brighter, more fluorescent appearance. This is how you create custom fluorescent-tinted Pantone shades.

Blocker Escalation — Which Blocker, When?
The blocker prints FIRST, directly on the garment, UNDER the white underbase. Three levels:
Level 1 — Under Base Blocker Gray: Standard dye migration on dark cotton. The default starting point.
Level 2 — Under Base Blocker Black LG: Stronger blocking for polyester, poly-blends, and aggressive dye migration.
Level 3 — Kombat Blocker: Most aggressive. For sublimation-printed polyester.
No blocker needed: Light garments and discharge printing.
Always test — 48-hour rule: Print, cure, wait 48 hours. If dye bleeds through, escalate blocker level.
How to Choose the Right Base for Your Fluorescent Yellow
Maximum neon on white/light shirts: 301C Clear or EasyPrint Clear + Glow Yellow ECGG (15-20%). Maximum neon pop.
Fluorescent yellow on dark cotton: Brite Discharge Base + Glow Yellow ECGG + Discharge Activator.
One fluorescent mix for lights and darks: 301DM Base + Glow Yellow ECGG.
Fluorescent yellow on stretch/activewear: Stretch Clear 301 + Glow Yellow ECGG. High-vis athletic prints.
Fluorescent yellow on nylon/polyester: Soft-Tex Base 350 + Glow Yellow ECGG.
Fluorescent metallic gold-yellow: Gold Shimmer 620 + Glow Yellow ECGG (up to 5%).
Toned-down fluorescent yellow: Blend Glow Yellow ECGG with Neo Yellow M3G in any base to control neon intensity.

FREQUENTLY ASKED QUESTIONS
Does Glow Yellow ECGG glow in the dark?
⚠️ NO. Despite the name “Glow,” this is a FLUORESCENT pigment, not a phosphorescent glow-in-the-dark pigment. It produces intense, high-visibility neon yellow under normal daylight and UV/blacklight conditions. It does NOT emit light in the dark.
Can I print Glow Yellow ECGG by itself?
⚠️ NO. It must be mixed with a Matsui base before printing. Without a base, the pigment will not adhere to fabric.
How much pigment do I add?
Up to 20% by weight for most bases — higher than Neo Pigments (10-15%). Discharge bases: up to 15%. Pearl Binder: max 2%. Shimmer: max 5%.
Can I mix Glow Pigments with Neo Pigments?
Yes — blend Glow and Neo Pigments together for custom fluorescent-tinted shades. Add a small amount of Glow Yellow to standard Neo color formulas for a fluorescent boost. Blend with Glow Orange ECR for fluorescent amber. Blend with Glow Green EC5G for electric chartreuse.
Which base gives the most fluorescent impact?
301C Clear or EasyPrint Clear on white or light garments. White fabric reflects light through the fluorescent pigment for maximum neon effect.
Do I need a blocker on dark garments?
If using water-based (non-discharge) base on darks, yes. Gray for dark cotton, Black LG for polyester/blends, Kombat Blocker for sublimation poly. Discharge bases: NO blocker needed.
Is it safe for children’s garments?
Yes. OEKO-TEX® Standard 100 certified, CPSIA and HR4040 compliant.
