Inktek 9925 Neon Pink Plastisol Ink – Bright Fluorescent Ink for Screen Printing

Inktek

Inktek 9925 Neon Pink is a high-opacity, low-cure fluorescent plastisol ink that delivers electric, eye-catching pink prints on cotton, cotton blends, and polyester. Its white-boosted formula pushes fluorescent pigment intensity beyond what standard plastisol can achieve — blazing hot pink that holds its vibrancy from press to dryer to finished garment. Non-phthalate. Matte finish. Soft hand. Cures at 280°F.

Description

Neon Pink That Actually Looks Neon.

Most “neon” plastisol inks deliver something closer to bright pink than true fluorescent. Inktek 9925 is different. A proprietary white-boosted fluorescent formula pushes the pigment load past what standard plastisol can carry — the result is a saturated, electric hot pink that holds its intensity under press conditions, through the dryer, and on the finished garment. If you print festival merch, charity run apparel, sorority gear, breast cancer awareness shirts, or any design where the customer expects the ink to jump off the fabric, this is the ink for the job. It also glows intensely under UV and blacklight — no specialty formula required.

White-Boosted Fluorescent Formula
Standard fluorescent pigments are semi-transparent. Inktek 9925 adds a white carrier to the formula, amplifying opacity and pushing the neon intensity higher. You reach full color saturation faster, on fewer mesh passes, using less ink.
UV and Blacklight Reactive
Fluorescent pink pigments absorb UV light and re-emit it as visible hot pink — which is why neon inks pop under blacklights and in low-light settings. Inktek 9925 performs in both ambient daylight and UV-lit environments without any modification.
Soft Hand · Matte Finish
Prints with a smooth, creamy body through 86–305 mesh. The cured result is a soft, flexible hand feel with a matte finish — no stiff plasticky texture, even on higher-mesh fine-line work. Wet-on-wet capable for multi-color builds.
Low Cure — 280°F Max
Fluorescent pigments are heat-sensitive. Overcuring above 300°F degrades the fluorescent dye and the color dulls to a flat standard pink. The 280°F cure ceiling protects color vibrancy. Always verify with a donut probe — not a surface gun.

Dark Garments: The Right Approach

Neon pink plastisol is semi-transparent by nature — the fluorescent pigments that make it glow also make it unable to block dark fabric from showing through. On any garment darker than a mid-gray, an underbase is mandatory for full color intensity.

Light Garments (White, Ash, Pastel)
Print Inktek 9925 directly. No underbase needed. Full fluorescent intensity from a single hit. Best results on 100% cotton or cotton/poly blends.
Dark Garments (Black, Navy, Charcoal)
Print white underbase → flash → print 9925 on top. The white base reflects light back through the fluorescent pink, maximizing neon intensity. Print-flash-print gives the brightest possible result.
Polyester / Blends
Use a gray or low-bleed blocker under your white underbase to prevent dye migration from the garment bleeding into the neon layer. The 280°F cure helps, but blocking is critical for poly-heavy fabrics.

Best Use Cases for Neon Pink Plastisol

Festival & Concert Merch
Neon pink is a festival staple — high-energy, UV-reactive, and visible in both daylight and blacklit environments.
Charity Runs & 5Ks
Breast cancer awareness, fun runs, and charity walks. High-visibility neon pink is the default color palette for these programs.
Sorority & Greek Apparel
Rush events, formals, and sorority merch frequently call for hot pink and neon accents — this ink delivers.
Athletic & Sport Apparel
Neon pink accents on performance wear. Low cure is safe on moisture-wicking polyester blends when used with a proper blocker.
Fashion & Streetwear
Bold neon graphics on black, white, and neutral garments. The soft hand and matte finish work for premium fashion applications.
Blacklight Event Gear
UV parties, glow runs, and blacklight events. Inktek 9925 glows intensely under UV without any specialty additives or treatment.
⚠️ Don’t Overcure Neon Inks
Curing above 300°F permanently degrades fluorescent pigments and the color shifts to a flat, dull pink. Target 280°F internal ink temp. Verify with a donut probe. Adjust belt speed before going into production — not during.
⚠️ White Underbase Required on Darks
Printing neon directly on dark garments without an underbase will result in a muted, washed-out color. The white underbase is what makes the neon pop. Do not skip this step on any garment darker than light gray.

Available Additives

Inktek 9925 can be modified with standard plastisol additives: curable reducer (thin for finer mesh), stretch additive (elastic garments), fashion base (softer hand), and finesse base (smooth lay). Do not add more than the recommended percentages — over-reduction dilutes fluorescent pigment concentration and reduces neon intensity.

⚠️ Adding reducer to neon inks is more visually impactful than with standard plastisol — even small amounts of thinning can noticeably reduce the fluorescent color intensity. Test before production.

Cure Verification — Critical for Neon Inks
Because fluorescent pigments degrade with heat, standard “turn up the dryer” troubleshooting can permanently damage the color before the ink is even cured. Always use a donut probe to verify internal ink temperature, not a surface pyrometer. Stretch test every color on your actual garment fabric before a production run. If the ink stretches and doesn’t crack, cure is complete.

FREQUENTLY ASKED QUESTIONS

Do I need an underbase to print neon pink on dark shirts?
Yes — without exception. Neon pink plastisol is semi-transparent. The fluorescent pigments that make it glow cannot block a dark garment substrate. Print a white underbase first, flash it fully (not just gel), then print the neon on top. For the maximum neon intensity on dark garments, use print-flash-print: print white, flash, print neon, flash, print a second hit of neon.
Why does my neon pink look dull after curing?
The most common cause is overcuring. If the internal ink temperature exceeds 300°F, fluorescent dyes in the ink permanently degrade and the color shifts to a flat, washed-out pink. This cannot be reversed. Verify your dryer temperature with a donut probe before running neon colors, and reduce belt speed to find the 280°F sweet spot. The second most common cause is printing directly on a dark garment without a white underbase — the substrate absorbs the fluorescent effect entirely.
Does Inktek 9925 Neon Pink actually glow under blacklight?
Yes. Fluorescent pink pigments absorb UV wavelengths and re-emit them as visible pink light — which is what makes them appear to glow under UV/blacklight. Inktek 9925 contains these same fluorescent pigments and will glow intensely under blacklight without any modification, specialty topcoat, or UV-reactive additive. For maximum glow, print on white or use a white underbase on dark garments.
Can I print neon pink on polyester or 50/50 blends?
Yes, with the right setup. On polyester or poly-blend dark garments: print a gray or low-bleed blocker first, flash, print white underbase, flash, then print neon. The blocker prevents reactive garment dyes from migrating into and contaminating the bright neon layer. The 280°F low-cure formula helps limit dye migration compared to standard 320°F plastisol, but blocking is still critical on poly-heavy fabrics. On white or light polyester, you can print more directly — but always run a test.
What mesh count should I use for neon pink plastisol?
Inktek 9925 runs through 86–305 mesh. For solid fills and bold graphics where maximum ink deposit and brightness are the priority, use 86–110 mesh. For detail work or fine halftones within a neon design, 155–200 mesh works well. Go above 230 only when detail truly requires it — finer mesh deposits less ink and reduces the fluorescent intensity of the finished print.
What’s the difference between Neon Pink and Neon Magenta?
Inktek 9925 Neon Pink is a bright, saturated hot pink — warm-leaning with strong red undertones, closer to what most people picture as “hot pink.” Neon Magenta (LB9975) sits further toward the blue-red spectrum, with a cooler, more violet-adjacent tone. If your customer’s design calls for a classic neon hot pink or breast cancer awareness pink, 9925 is the right choice. If the brief says “magenta” or a Pantone that leans purple-red, look at 9975.
Does River City Supply ship neon pink same day?
