Description

The Foundation of Every Pantone Formula.

White is the most consumed ink in any shop running Pantone color matching — and for good reason. Every pastel, every tint, every lightened formula starts with white. Inktek LBX White is engineered specifically for the LBX Pantone Mixing System: a high-opacity, low-cure plastisol base that tints cleanly, underbases reliably, and mixes predictably with all 14 other LBX bases. Use the free LBX Pantone Color Formulator at formulator.screenprintsupplies.com to get exact gram-weight ratios for any Pantone target instantly.

Why LBX White?

The Most-Used Base in the System

Nearly every Pantone formula in the LBX system calls for white — it’s the universal tint base that lightens any color toward a pastel and controls value across the entire color range. If you’re running the LBX system, you’ll go through white faster than any other base. Stock accordingly.

High-Opacity Underbase Performance

LBX White isn’t just a mixing component — it’s a fully capable underbase ink. The high-opacity formula lays down a clean white foundation on dark and medium-tone garments, giving your top colors a neutral surface to print on for accurate, vibrant results.

Clean Pastel Mixing

Pastel Pantone targets — baby blues, soft pinks, lavenders, mint greens — are achieved by adding small amounts of color bases to a large white base. LBX White accepts other LBX inks cleanly without shifting or muddying the mix, producing smooth, true-to-formula pastel results.

Low Cure for Performance Fabrics

Full cure at 280°F means LBX White is safe for polyester, tri-blends, and athletic wear — whether you’re using it as a mixed tint color or as a standalone white underbase. Lower cure temps also reduce dye migration risk when underbasing on poly-heavy dark garments.

Available Sizes

  • QQuart (32 oz) — Good for shops getting started with LBX or supplementing an existing white supply
  • GGallon (128 oz) — The standard production size; most shops running LBX should keep multiple gallons on hand
  • 55-Gallon Pail — High-volume contract shops and operations running heavy Pantone mixing or large underbase programs daily

Three Ways to Use LBX White

1 — As a Pantone Tint Base

Use the free formulator at formulator.screenprintsupplies.com to get exact gram-weight ratios. Weigh the white and color components on a digital gram scale, mix thoroughly, and you have a repeatable Pantone match every time.

2 — As a Standalone Underbase

Print LBX White through 86–110 mesh as a first-down underbase on dark or medium-tone garments. Flash at 180–220°F surface temp until dry-to-touch, then print your top colors. The high-opacity formula provides a clean neutral foundation for accurate color reproduction.

3 — As a Pastel Base

For soft pastel Pantone targets, start with a large white base and add very small, weighed amounts of the appropriate color base. The formulator handles the math. Mix completely — any unmixed streaks will show in the print as color variation.

4 — Cure at 280°F

Whether used as a mixed tint, straight white, or underbase, full cure is 280°F internal ink temp. Use a donut probe or thermocouple — not a surface gun — to verify. Do a stretch test and wash test before shipping customer orders.

What LBX White Helps You Hit

Pastel Pantone Targets

PMS 9141, 9162, 9300, 9420 and the full pastel family — LBX White is the dominant base in every formula

Light & Mid-Tone Colors

Any light-value Pantone — sky blues, warm creams, soft greens, blush pinks — requires significant white content to achieve the correct value

White Underbase Layer

Direct underbase printing on black, charcoal, navy, and medium-tone garments — provides the high-opacity foundation that makes top colors pop

Straight White Prints

Single-color white jobs on colored garments — LBX White prints clean and opaque straight from the container, no mixing required

LBX White vs. Standard White Plastisol

Tinting Consistency ✔ Predictable & Repeatable Inconsistent Results
Safe for Poly & Performance Wear ✔ Yes Risk of Scorching
Underbase Performance ✔ High Opacity Varies by Product
Free Formulator Software ✔ formulator.screenprintsupplies.com None

⚠ Stock More White Than You Think You Need

White is consumed at a much higher rate than any other LBX base. Pastel formulas are predominantly white with trace amounts of color — a gallon of white might produce only a few batches of light pastels. Plan your inventory accordingly and keep extra white on the shelf.

⚠ Don’t Substitute Other Whites

LBX White is formulated specifically for use in the LBX mixing system. Substituting a different white — from another brand or product line — will throw off your Pantone formulas. The pigment load, tinting strength, and rheology all affect the mix. Stay in-system for consistent results.

LBX White Is a Pantone Mixing Ink — Not Just a White

LBX White is engineered as a precision mixing base — one of 15 fully inter-mixable LBX inks designed to hit specific Pantone targets by weight. Use the free LBX Pantone Color Formulator to get exact gram-weight mix ratios for any Pantone color instantly. No guessing. No waste. Repeatable run after run.

FREQUENTLY ASKED QUESTIONS

Why is LBX White considered the most-used base in the system?

White is the dominant component in the majority of Pantone formulas — particularly any light-value, pastel, or tinted color. Even mid-range colors often require significant white to achieve the correct lightness. As a result, shops running the LBX system consume white at a much higher rate than any other base. It’s also used as a standalone underbase ink, which adds to consumption. Most shops should stock white in gallon or 5-gallon quantities and keep backup supply on hand.

Can I use LBX White as a standalone underbase?

Yes — LBX White is a high-opacity formula and performs well as a white underbase on dark and medium-tone garments. Print through 86–110 mesh, flash at 180–220°F surface temp until dry-to-touch, then print your top colors wet-on-flash. It’s the same ink you’re already using for mixing, so no need to stock a separate underbase white.

Can I substitute a different white ink in my LBX formulas?

No — the LBX formulas are calibrated specifically to LBX White’s pigment load, tinting strength, and rheology. Substituting a different white — even from a comparable brand — will throw off your Pantone matches. The tinting strength of white varies significantly between products, so even small deviations produce visible color shifts, especially in light pastels where white makes up 80–95% of the formula. Stay in-system for consistent, repeatable results.

How do I use the free LBX Pantone Formulator?

Go to formulator.screenprintsupplies.com — no account or login required. Enter your Pantone target and the tool returns exact gram-weight ratios for each LBX base needed to hit that color. Weigh your components on a digital gram scale accurate to 0.1g, mix thoroughly, and you’re ready to print. The formulator runs in any browser on any device and is completely free.

Is LBX White safe on polyester and performance wear?

Yes — full cure at 280°F means it won’t scorch poly fabrics or damage moisture-wicking and other performance treatments. The lower cure temp also reduces the risk of heat-activating dye migration on polyester garments when used as an underbase, which is a common problem with standard-cure whites running at 320°F.

How do I confirm the ink is fully cured?

Use a donut probe or thermocouple to verify the internal ink temp reaches 280°F — surface temperature guns are not accurate enough for cure verification. Do a stretch test: fully cured plastisol stretches without cracking. For production runs, periodic wash tests (3–5 hot wash cycles) confirm durability before customer orders ship.

Does River City Supply ship same day?

Yes — orders placed before 3:30 PM CT Monday through Friday ship the same day. Free shipping applies automatically on orders over $200. Call us at (512) 454-0505 or email [email protected] with any questions.
