Greyback Knit Fabric —

Premium Fabric, Opacity for Vibrant Graphics

Greyback Knit is a Premium Fabric with Opacity to ensure your graphics look vibrant, and just the right amount of stretch for a wide range of applications.

We know the brands and retailers we work with put their all into their graphic design, and they want their branding to look great. What you can't always control are where your graphics go. When fabric graphics are put into positions where windows or lights shine behind fabric graphics, the light can wash out your branding.

That’s why we developed our Greyback Knit Fabric, a premium blockout textile engineered to deliver vivid, high-contrast graphics with great opacity.

Unlike standard fabrics that can wash out your colors by allowing background light to bleed through, Greyback Knit features gray fabric sewn right into the fabric that acts to block lighting bleed through. This opacity keeps your visuals clean, bold, and professional in any environment. This fabric it the perfect choice when you need rich color without distraction from what’s behind your display.

Why Our Greyback Knit Fabric Stands Out

  • Blockout Backing – Prevents light from passing through so graphics stay crisp even in bright environments. A single layer of fabric significantly reduces light while a double layer, like a pillowcase banner stand, blocks out nearly all light.

  • Vivid Color Reproduction – Optimized for dye-sublimation printing, greyback knit delivers sharp, vibrant results that look great even if brighly lit environments.

  • Wrinkle Resistant & Reusable – Lightweight yet durable fabric resists creasing for easy shipping and reinstallation. The sewn in light blocking fabric means there's no separate light blocking layer nor any nasty plsatic coatings to create unseamly wrinkles. This fabric has the perfect amount of stretch.

  • Versatile Applications – Ideal for pillowcase banner stands, hanging fabric graphic displays, trade show displays, and window hanging banners.

  • Testrite Quality –  Printed and finished at our New Jersey facility for fast turnaround and strict quality control. We specialize in tight integration between fabric graphics and our Made in USA hardware solutions.

Greyback Knit Fabric – Frequently Asked Questions

What is greyback knit fabric?
Greyback knit is a high end printable polyester fabric. It is designed to block out light to help your graphics to look great, even if there is lighting or windows behind your graphics. This material has grey fabric sewn right into the rear of the fabric. This is NOT a plasticy coating, it’s achieved with fabric. What this provides is the stretch needed for pop-up graphics and pillowcase graphics while providing great light blocking. This product also avoids having to invest in sewing in a separate light blocker. Note, light blocking ability is enhanced when used in two layers, for example as a pillowcase banner stand that has fabric on the front and back.
What is greyback knit fabric ideal for?
Greyback knit is ideal for non-lit applications where you need rich vibrant colors and don’t want your graphics getting washed out by a bright room, nearby lighting, or nearby windows. This is the ideal fabric for tension fabric frames, fabric banner stands, trade show graphics, hanging banners, and retail displays. Nearly any application that benefits from a bit of stretch.
Why choose greyback knit over standard stretch or soft knit fabrics?
Standard fabrics, if there’s lighting behind them, tend to allow light to pass through. This normally wouldn’t affect a wall mount frame. When you put a banner stand in a stadium or retail store near a window, the wonderful natural light can wash out the look of your brand imagery. Greyback knit helps to block out this ambient light, helping to ensure your graphics appear bold and solid even with bright lighting behind them.
Is greyback knit fabric wrinkle resistant and reusable?
Yes! Greyback knit is engineered to resist wrinkling, making it easy to fold, ship, and reinstall. Stretching the fabric across your frame will allow any creases to ease out over time. It has the perfect amount of stretch for use in our US Made Pop-Up Banner Stand and in Testrite’s industry best pillowcase banner stands. This premium fabric is durable, and perfect for repeated use.
