Best White Plastisol Ink for Screen Printing Shops

Written by Lauren Salzman | Aug 28, 2026, 9:13:52 PM

Not every white plastisol ink behaves the same way once it hits the platen. A white that mats down beautifully on a heavyweight cotton hoodie can bleed or ghost the moment it's cured onto 100% polyester athletic wear, and the wrong cure temperature can shrink a heat-sensitive garment before the ink even sets. The real question for most shops isn't which ink is "best" in the abstract; it's which formula matches the fabric, mesh count, and press setup already running through the shop. Grimco is an authorized distributor of Wilflex, Union Ink, and Rutland plastisol inks, covering both ends of that spectrum, from everyday cotton and poly-blend work to high-bleed-resistance polyester and performance fabrics.

1. Wilflex Amazing Bright Tiger White

Best Uses for Cotton and Poly-Blend Garments

Amazing Bright Tiger White is a versatile powerhouse that excels as both an underbase and a standalone white. This non-phthalate ink delivers premium opacity with a brilliant white finish and excellent fiber mat-down. It works beautifully across a wide range of mesh counts and handles everything from manual to automatic presses with ease. The ink cures at 300°F and offers moderate bleed resistance, making it ideal for cotton and cotton/polyester blends.

Production Benefits for Screen Print Shops

For print shops that need one reliable white ink that can handle multiple applications, Amazing Bright Tiger White is a smart investment. Its versatility means you can use it for flash whites, highlight whites, and direct printing without switching products. The creamy consistency makes it user-friendly, and its ability to print through various mesh counts from low to high gives you flexibility in your production workflow. The soft hand feel and matte finish hold up well against current customer expectations for print texture.

Shop-Tested Results for Daily Production

"The Bright Tiger white has a few properties I prefer over some brands. It is creamy and won't drag across the screen after printing. It is a superior base white with awesome printability on top colors," shares one experienced print shop customer. Another adds, "Halftones print amazing even on 300 and up mesh counts, and it cures to a nice matte finish and stretches like no other."

2. Union Ink UPLC1071 Sport LC Poly White

Best Uses for 100% Polyester and Performance Fabrics

Union Ink UPLC1071 is a specialized low-cure, low-bleed white designed specifically for 100% polyester fabrics. Part of Union's Gen 2 Sport LC line, this ink offers excellent bleed resistance and superior dye blocking capabilities. It cures across a range as low as 270°F, which helps prevent dye migration and reduces energy consumption. The improved formula provides a creamy consistency, softer hand, and matte finish with enhanced fiber mat-down.

Dye Migration Control for Athletic and Performance Wear

If you're printing on polyester athletic wear or performance fabrics, UPLC1071 solves the common nightmare of dye migration. Curing at the lower end of its range prevents those frustrating instances where garment dyes bleed through your print. The lower cure temperature also means faster production times, reduced shrinkage on heat-sensitive fabrics, and lower energy costs. For shops specializing in sports uniforms or polyester garments, this ink is practically essential equipment.

Real-World Performance for High-Volume Runs

This ink is part of the Sport Victory Colors line approved by BSN Sports as part of their Core 24 product portfolio, indicating it meets rigorous standards for athletic apparel printing. The Gen 2 formulation represents Union Ink's commitment to improved printability while maintaining excellent bleed resistance and opacity on challenging polyester substrates.

For printers working with performance wear and polyester fabrics, UPLC1071 offers the specialized performance needed to deliver quality prints that last.

The ink features optical brighteners to maintain brilliant whiteness under various lighting conditions, and it mats down garment fibers beautifully for smooth, professional prints.

Production Advantages for High-Volume Screen Printing

Street Fighter 2 LB is designed to be a shop's go-to daily driver for cotton/polyester blends. The fast flash time means higher productivity, while the low after-flash tack eliminates the need for cool-down stations.
