Description

Monarch ULT II White — The Ultra-Low-Temp 100% Poly White

When the fabric is 100% polyester and the dye wants to bleed, you need the lowest cure and the best dye blocking you can get. ULT II cures as low as 270°F — keeping heat off the garment to prevent migration and shrinkage — with excellent bleed resistance, a soft, stretchable hand, and bright, high opacity. Short body, low tack, prints from the bucket. And it doubles as a hot-peel transfer ink.

Why Poly Printers Run ULT II

Ultra-Low Cure (270°F)

Cures as low as 270°F for the best energy savings, dye blocking, and shrink prevention on heat-sensitive synthetics.

Best-in-Class Bleed Resistance

Excellent dye-migration resistance on 100% polyester and performance blends — keeps white white.

Soft & Stretchable

A soft, stretchable hand that moves with athletic apparel — no stiff, heavy patch of ink.

Hot-Peel Transfer Capable

Doubles as a hot-peel transfer ink — pair with a low-temp transfer adhesive that releases at 260°F.

High Opacity, No Ghosting

Bright, opaque, one-pass coverage with clean, crisp prints and no ghosting.

Non-Phthalate & Universal

Phthalate-free and lead-free, and prints on virtually any fabric — poly, blends, cotton, nylon, stretch, polypropylene.

What You Get & What You Need

Monarch ULT II White plastisol — non-phthalate, ultra-low-temp, high bleed resistance.

Best on 100% polyester and athletic apparel; also tri-blends, poly blends, cotton, nylon, stretch/lycra, and polypropylene (pretest nylon).

Doubles as a hot-peel transfer ink — pair with a low-temp transfer adhesive (releases at 260°F).

For waterproof-coated fabrics: add CLA-100 adhesion promoter to the ink.

For severe dye migration: print over a barrier base underlay.

Dialing In ULT II White

1. Print

Stir first. Print straight from the bucket through 86–156 mesh with an 80 durometer (or 70/90/70) sharp blade. On poly, drop to 110–125 mesh for a heavier deposit and better dye blocking.

2. Flash

Short, fast flash — just dry to the touch. Avoid over-flashing, which causes inter-coat adhesion problems.

3. Cure

Cure at 270–300°F (as low as 270°F). Run a stretch test after curing, and let shirts cool before stacking — hot dyes can gas onto the next garment.

Which Monarch White Do You Need?

Why Ultra-Low-Temp

A lower cure keeps heat off polyester — the single biggest driver of dye migration and shrinkage — while saving dryer energy. That’s why ULT II is the poly and athletic-apparel choice.

Doubles as a Transfer Ink

Print ULT II onto hot-peel transfer paper and pair with a low-temp transfer adhesive (releases at 260°F) for efficient, low-heat heat-transfer printing.

When to Switch

Printing cotton or 50/50? Use Stark White LB. Poly blends and everyday jobs? Yeti LB. Want one creamy all-rounder? See Summit White LB.

Before You Run It

Go easy on additives. Modifiers and additives can reduce ULT II’s ability to stop dye migration and bleed — mix minimally and only in clean containers.

Cool before stacking. Let cured shirts cool before stacking — hot dyes can gas off and transfer onto the back of the next garment. Split into a few stacks.

Cure low, but cure fully. Cures as low as 270°F, but always run a stretch/fusion test. Higher end or longer dwell may be needed on cotton, heavy deposits, or heavy garments.

Pretest tricky fabrics. Not suitable for all nylon substrates — pretest. For severe migration on poorly dyed poly, print over a barrier base underlay.

Match the white to your fabric

100% poly / transfers → ULT II. Cotton/50-50 → Stark White. Poly blends → Yeti LB. All-rounder → Summit White. See the full Monarch white lineup.

FREQUENTLY ASKED QUESTIONS

Monarch ULT II White — Frequently Asked Questions

What is ULT II White best for?

100% polyester and athletic/performance apparel where low cure and dye blocking matter most — and hot-peel heat transfers. It’s the ultra-low-temp white in Monarch’s lineup.

How low does it cure?

As low as 270°F. The low cure gives the best energy savings, dye blocking, and shrink prevention on heat-sensitive synthetics — always run a stretch/fusion test to confirm a full cure.

How good is its bleed resistance?

Excellent on 100% polyester — it’s Monarch’s most migration-resistant white. For poorly dyed poly or severe migration, print over a barrier base underlay.

Can I use it as a heat-transfer ink?

Yes — ULT II doubles as a hot-peel transfer ink. Print it onto hot-peel transfer paper and pair it with a low-temp transfer adhesive that releases at 260°F.

What mesh should I use?

86–156. On polyester, drop to 110–125 mesh for a heavier deposit that boosts coverage and dye blocking. Use an 80 durometer or 70/90/70 sharp blade.

How is ULT II different from Yeti and Stark?

ULT II is the ultra-low-temp 100% poly white with the best bleed resistance and transfer capability. Yeti LB is the poly/blend white at a low cure; Stark White LB is the cotton/50-50 white at a standard 320°F cure.

Do additives affect performance?

They can. Modifiers and additives may reduce ULT II’s ability to stop dye migration and bleed — mix minimally, in clean containers with clean blades, and test before production.

Any tips on stacking finished shirts?

Let cured shirts cool before stacking — hot dyes can gas off and transfer onto the back of the next garment. Split into a few stacks so each has time to cool.

Is it non-phthalate and kid-safe?

Yes — non-phthalate and lead-free, safe for children’s apparel. Keep it uncontaminated by mixing additives in clean containers.

How should I store it?

At room temperature, out of direct sunlight and away from heat — it’s a low-cure ink and heat can gel it. Keep containers tightly sealed.

Can I match Pantone colors?

Yes — build custom Pantone shades in plastisol with the Monarch VIVID LB mixing system.
