Description

The Bright White That Moves With the Shirt.

Performance wear is everywhere — athletic jerseys, compression tights, moisture-wicking polos, yoga apparel, leggings, cycling kits. These garments stretch constantly, and a standard plastisol white will crack the moment they do. LB028 Bright Stretch White solves that problem by combining the optic-white brightness and high opacity of the LB020 Bright White with Inktek’s stretch additive pre-mixed in at the factory. You get a ready-to-print stretch white — super soft hand, flexible film, crack-resistant coverage — without measuring additives, mixing batches, or testing ratios. Open the container, print, and the stretch is already there. Low-cure at 280°F, non-phthalate, and built for every piece of performance apparel your customers bring through the door.

Why LB028 Bright Stretch White?

No Measuring. No Mixing. Just Print.

Getting the right stretch ratio by mixing additive into standard white is a calibration exercise — too little and it still cracks on stretch fabrics, too much and opacity suffers. LB028 removes that variable entirely. The stretch additive is pre-mixed at the factory to the correct ratio for performance wear. Open the container and print with confidence that the flexibility is already optimized.

Optic-White Brightness That Stays White

Adding stretch additive to standard white inks typically reduces opacity and shifts the color slightly off-white. LB028 maintains the optic-white brightness of the LB020 foundation despite the built-in stretch additive — you get the vibrant, high-opacity white your customers expect on the front of a jersey or compression top, not a compromised version of it.

Super Soft Hand for Athletic Wear

Athletic and performance garments are worn tight and felt constantly — hand feel matters more here than almost anywhere else in screen printing. LB028’s formulation is exceptionally soft after cure, draping and flexing with the fabric rather than sitting rigid on top of it. Athletes wear these garments to work out. The print needs to feel like part of the shirt.

Crack-Resistant on High-Movement Fabrics

Compression garments, spandex blends, and performance fabrics stretch 30–50% or more in normal use. Standard plastisol films can’t handle that range of elongation without cracking. LB028’s flexible film moves with the fabric through every stretch and recovery, maintaining print integrity wash after wash and workout after workout.

Press Settings for Performance Fabrics

Mesh Selection

86–305 mesh monofilament. For underbase work on dark performance garments, use 86–160 mesh for a heavy, opaque deposit. For spot color on lighter fabrics or finer design detail, 200–305 works cleanly with LB028’s flowing consistency.

Off-Contact & Tension

Performance fabrics stretch and rebound. Ensure proper off-contact distance to avoid ink smear on snap-back. Use well-tensioned screens — low-tension screens on stretchy substrates are a primary cause of registration shift and ink smear on athletic wear.

Cure

Gel temp 155–165°F for flash step. Full cure at 280°F internal ink temp for 1 minute 30 seconds minimum. Verify with a donut probe — not a surface gun. On stretchy fabrics, a properly cured stretch ink will pass the stretch test without cracking. If it cracks, it’s undercured.

Pallet Adhesive

Stretchy fabrics require sufficient pallet adhesive to hold them flat during printing — especially compression garments that want to roll or shift. A good adhesive bond keeps the fabric dimensionally stable so your print stays registered through every color.

LB028 Bright Stretch White vs. LB020 Bright White — Which Do You Need?

Feature LB028 Bright Stretch White LB020 Bright White
Stretch Additive Pre-mixed in — ready to print Standard — can add separately
Film Flexibility High — engineered for stretch fabrics Standard plastisol flexibility
Hand Feel Super Soft Ultra-Soft
Cure Temperature 280°F 280°F
Finish Matte Semi-Matte
Best Substrates Performance wear, spandex blends, stretch fabrics Cotton & cotton blends
Crack on Stretch No — flexible film May crack on high-elongation fabrics
Best Fit Athletic, compression, performance, team uniforms Retail tees, fashion, soft goods
⚠ The Stretch Test Is Your Cure Verification

With stretch inks, the stretch test is even more important than with standard plastisol. After curing, pull the fabric hard in both directions. If the print cracks at all, the ink is undercured — even if it passed a surface temperature check. Undercured stretch ink that passes initial inspection will crack in the field after the garment has been worn and washed a few times.

⚠ Use a Blocker on 100% Polyester

LB028 is formulated for cotton, cotton blends, and stretch fabrics with cotton content. For 100% polyester performance garments — especially dark-colored ones — always underbase with a dye-migration blocker before printing LB028 on top. The stretch additive doesn’t add polyester blocker properties.

FREQUENTLY ASKED QUESTIONS

Why not just add stretch additive to LB020 Bright White myself?

You can — but the right ratio matters. Too little additive and the ink still cracks on high-stretch fabrics. Too much and opacity drops and the color shifts slightly off-white. Getting the ratio right requires testing, and it introduces a variable into every batch you mix. LB028 removes that variable entirely — the stretch additive is mixed at the factory to the correct ratio for performance wear, so every container performs identically. Open and print.

Will LB028 really not crack on compression garments and spandex?

When properly cured, yes — the flexible film is designed to move with high-elongation fabrics through their full stretch range. The key is proper cure: the ink must reach 280°F internal temp for at least 1 minute 30 seconds. Undercured stretch ink will crack in the field even if it survives the initial stretch test. Always verify with a donut probe, do a hard stretch test, and wash test before shipping any performance wear jobs.

Can I use LB028 on 100% polyester jerseys?

LB028 is formulated for cotton, cotton/poly blends, and stretch fabrics with cotton content. On 100% polyester — especially dark-colored performance fabrics — dye migration is a real risk. Use a dye-migration blocker as the first-down underbase, cure it, then print LB028 on top. The stretch additive in LB028 doesn’t provide blocker properties. Always test on the specific garment colorway before production.

What’s the difference between LB028 and LB020 Bright White?

LB028 is LB020 Bright White with stretch additive pre-mixed in. They share the same optic-white brightness, high opacity, and 280°F cure temp. The difference is film flexibility: LB028 is designed for stretch fabrics and moves with the garment; LB020 is the standard version for cotton and cotton blends where stretch isn’t a requirement. If your customer is wearing it to a workout, use LB028. If they’re wearing it to a concert, LB020 is fine.

How do I handle stretchy fabrics on the pallet to get clean registration?

The two main issues with printing stretch fabrics are fabric creep on the pallet and screen snap-back distortion. For fabric creep: use a fresh coat of pallet adhesive and load the garment carefully, keeping it flat and square. For snap-back: use well-tensioned screens and proper off-contact distance so the screen lifts cleanly rather than dragging. On compression garments specifically, load them slightly stretched so they lay flat against the pallet during printing.

Does LB028 print wet-on-wet?

Yes — LB028 has excellent wet-on-wet performance. For dark garments where you need maximum underbase opacity, a flash step will produce better results. For light garments or simpler designs on stretch fabric, wet-on-wet is a viable approach. Test both methods on your specific garment and design before committing to a production workflow.
