SubliBloc (Sublimation Blocker)

Why It Matters: Impact and Use

In the high-performance sportswear and teamwear industry, Dye Migration is a common technical failure that undermines E-E-A-T (Expertise, Authoritativeness, and Trustworthiness). Without a SubliBloc layer, a vibrant white logo applied to a red polyester jersey will slowly turn pink over time as the fabric dyes “gas out” into the vinyl.

• Optimizing ROI: While SubliBloc media may have a slightly higher upfront cost, it eliminates the need for expensive “re-dos” and customer returns caused by faded or discolored logos, significantly improving your long-term ROI (Return on Investment).
• Preventing “Bleeding”: Polyester is colored via sublimation, where dyes are bonded to fibers using intense heat. When you reheat that garment to apply a transfer, those dyes can reactivate. SubliBloc contains a charcoal or aluminum-based layer that physically traps these gaseous dyes, maintaining the original color of your print.
• Low-Temperature Application: Most SubliBloc films are engineered to activate at lower temperatures (e.g., 130°C – 140°C). By reducing the heat required for the transfer, the polyester dyes in the garment are less likely to reactivate, providing a secondary layer of protection against discoloration.
• Essential for High-Contrast Designs: The risk of bleeding is highest when applying light-colored transfers (White, Yellow, Neon) onto dark polyester garments (Navy, Red, Black). SubliBloc ensures that a “White” print stays “White” for the entire lifespan of the garment.
