Cover Sheets

A cover sheet is a protective layer placed between the heat press platen and the garment or transfer during pressing. It prevents scorching, protects the platen surface, and helps achieve a more even finish on transfers.

Common cover sheet types include Teflon (PTFE) sheets, parchment paper, and silicone sheets. Teflon sheets are reusable and most durable, parchment paper is disposable and inexpensive, and silicone sheets offer a soft surface for delicate transfers.

Teflon sheets are best for regular production use because they are durable, reusable, and provide consistent non-stick performance. Parchment paper is a good single-use alternative when a Teflon sheet is unavailable or when you need a fresh surface to avoid color contamination.

Yes, using the correct cover sheet can significantly improve transfer quality by ensuring even heat distribution and preventing the platen from imprinting texture onto the garment. Using no cover sheet can result in shiny marks or scorching on heat-sensitive fabrics.

Yes, Teflon sheets are designed to be reused many times. They should be replaced when they become discolored, develop stains that transfer to garments, show signs of melting, or develop areas that stick to transfers.

For most hot and cold peel transfers, a cover sheet is recommended on top of the transfer to protect the platen. For cold peel, press with the cover sheet, allow to cool, then peel. Some transfers may require pressing without a cover sheet — always follow the transfer manufacturer's instructions.

Cover sheets should be at least as large as the entire platen surface of your heat press to ensure full coverage. Common sizes include 12x15 inches and 16x20 inches to match standard platen sizes. Oversized sheets that hang over the platen edges are fine.

Yes, a Teflon cover sheet is commonly used in sublimation pressing to protect the platen from any ink that may bleed through the transfer paper. It also helps distribute heat evenly across the sublimation transfer area.

Silicone cover sheets provide a softer, slightly cushioned surface that can be beneficial for pressing rhinestones, sequins, or delicate embellishments where you need some give to avoid crushing or marking the design.
