Grey Blocker Underbase Plastisol Ink – 290–310°F Cure – Dye Migration Control

Grey Blocker Underbase Plastisol Ink is a high-opacity, low-bleed dye-migration blocker printed under your white and color layers on polyester, tri-blends and sublimated garments. The neutral grey traps the fabric's own dye so your top colors stay true instead of turning pink or yellow days later. CPSIA-compliant and phthalate-free, made in Hackensack, New Jersey.

Flash 230°F, full cure 300°F. Pint, quart, gallon and 5 gallon. Heat cure. Made in the USA.

Always run a test print first. Before any production run, print and fully cure a test on your exact garment and check opacity, hand and wash-fastness. It's the best habit in the shop — if you're not sure on settings, call us at 201-487-9600 before you run the job.

What it prints on

Printed as the first (underbase) layer, then topped with your white and color plastisol. Best on the dye-prone fabrics that cause migration:

• 100% polyester and sublimated garments
• Tri-blends and poly/cotton blends
• Multi-color prints on dark or dye-prone fabric
• Athletic and performance wear

Printing & curing

• Mesh: 110–160 for full underbase opacity (200+ for finer detail)
• Squeegee: 65, 75 or 80 durometer — or a 70/90/70 triple durometer for sharp edges with easy fill
• Flash: 230°F between layers before printing your top colors
• Cure: bring the full ink film to 300°F — always confirm with a temp gun or donut probe, not dryer air temp

Recommended companion products

• Quick Flash Reducer — thins the ink for easier printing and finer detail without killing opacity.
• Soft Hand Base — add for a softer, lighter hand feel on the garment.
• Badass Puff Additive — mix in for a raised, high-rise puff effect.
• UMX® Pantone® Mixing Colors (or the UMX® Mixing Kit) — match any Pantone® color in-house.
• Cleanup: OPTI Wash 125 (odor-free screen & tool wash) and OPTI Spot 303 (spot cleaning).

Safety, PPE & storage

• Wear nitrile gloves and safety glasses; avoid prolonged skin contact with uncured ink.
• Print with adequate ventilation; curing releases vapors — vent your dryer.
• Always stir the ink before use — standard practice to re-blend any settling.
• Storage & shelf life: keep sealed and out of direct sunlight. Shelf life is 1–2 years for standard inks; low-cure and all-polyester inks must be stored at 60–80°F. In high heat expect some expansion in the container — open carefully. Do not freeze.
• Uncured ink is not hazardous waste but should be handled and disposed of per local regulations.
• Refer to the Safety Data Sheet before use.

Compliance

CPSIA compliant — meets 16 CFR Part 1303 (<90 ppm lead in surface coatings) and CPSIA §101 (<100 ppm total lead); safe for use on children's apparel. Phthalate-free formulation.
