A teflon sheet is a sheet made of a material called teflon. You might want to consider purchasing a teflon sheet. Some heat presses come with one, but if not, they’re reasonably priced. While pressing, a teflon sheet protects your design. It’s non-stick, so no bits of heat transfer vinyl get stuck to your iron or press, and it protects your design from melting on your press.

Place the teflon sheet on the substrate when heat pressing to prevent the heating mat from polluting the image on the substrate. Heat pressing necessitates the use of Teflon. Teflon is the most stain-resistant material available, making it ideal for keeping your heat press and garments clean. Teflon is 5-mil thick, which means it will last 2-3 times longer than 3 mil. Teflon sheets can be used on both sides and are re-usable.


No worries, a thin tea towel will suffice. Although the towel is not non-stick, it will suffice.



A Teflon sheet (also known as a non-stick cover sheet) is required in any screen-printing company, whether it is a garage store or an industrial one. They’re the best for protecting your clothes while using a heat press, and they’re also wonderful for correcting printing errors.

A Teflon layer acts as a barrier between your garments and the platen, preventing them from melting. These are re-usable and will last a long time.

In this blog, we’ll look at how you may use Teflon sheets in your screen printing studio in a variety of ways. However, you must clean the Teflon sheets in between applications while utilizing them.

01. Removing ink deposits that aren’t even:

When screen printing, you’ll often notice that the ink on the t-shirt is too thick and uneven, which is especially typical when using heavier poly ink. Using a heat press and Teflon sheets is the best approach to solve this problem.

To cure the clothing, first run it through the dryer. Then take the garment to the heat press, where you’ll spend most of your time.

Place the garment on the press with the printed side facing up first. Place the Teflon sheet on top of the print at this point. Set the press’s temperature to 320 degrees Fahrenheit and the pressure to medium. Now press down for about ten seconds.

If you don’t have a heat press, you can still complete the work with an iron. Simply place the Teflon sheet on the fabric and iron it smooth with medium pressure. If you prefer a matte effect, use the non-glossy side of the sheets, and if you want a glossy finish, use the glossy side of the sheets.

02. Foil transfers:

Teflon sheets are a terrific place to start if you’re searching for a foil transfer process. The Teflon sheet is utilized in the same way that it was previously described in order to remove uneven ink deposits. In this case, though, you must first print and then cure your artwork. Then, on the print side, place the foil, then the Teflon on top of the foil, and press.

03. Creating heat transfers:

Teflon sheets can also be used to heat transfer graphics onto tees. You’ll need Teflon sheets if you’re doing this at an event. Heat transfers require placing the garment on the heat press and then placing the paper face down on the tee again. Place the Teflon sheet on top and press it down.

The top three uses of Teflon sheets in screen printing are listed below. Teflon sheets can help you solve a lot of screen printing problems and keep your shop busy.

04. Printing the garment on both sides:

Use a Teflon sheet inside the t-shirt to prevent heat from passing through the fabric while screen printing both the front and back of a garment.

This keeps the shirt from sticking to the opposite side of the garment, which is the plain side.

When working with stock lettering, you can alternatively use a Teflon sheet. You can easily peel and place each letter on the shirt using this method. Cover the letters with a non-stick Teflon sheet and press according to the directions once you’ve secured them with thermal tape.

05. Give the fabric a glossy finish:

If you want to give your fabric, such as a t-shirt, a glossy appearance, the Teflon sheet is the best option. Just put the Teflon sheet over the transfer and close the press for a few seconds after screen printing, as you were told to do.

Because of the luster added during the initial press, the fabric has a smoother finish. Teflon sheets might also be useful if you feel scorched on your garments when working with high temperatures or long dwell times.



Teflon sheets are often recommended for heat transfer applications. Teflon protects against direct contact with the heating element of a press and ensures even heat distribution across the garment’s surface. However, Teflon isn’t the best material for all thermal transfer applications. In fact, it has the potential to damage an expensive imprint. When should a Teflon sheet not be used for garment decoration?

When it comes to dye sublimation, there are a few things to keep in mind. The dye sublimation transfer papers are thinner and just serve to convey the dye ink to the polyester. The dye ink sublimes when heated to 400 degrees Fahrenheit. It turns into a gas and binds to polyester fabric or polymers on a coated substrate. But it isn’t all that occurs.

Some ink may migrate through the back of the transfer paper if your transfer paper is saturated with ink—which is likely if your SubliJET driver is set to “vivid.” If you’re using a Teflon sheet, the end result will be brilliantly decorated clothing and a not-so-beautifully decorated Teflon sheet.

This is merely a little annoyance because all you have to do now is either A) change the Teflon layer or B) make sure the imprinted region does not come into contact with an uncovered portion of the next shirt you press. However, if someone accidentally presses another shirt with the same Teflon sheet, your little annoyance turns into a big problem for the company.

In the name of science, I sublimated one of our shirt samples with a Teflon sheet and then pressed another shirt. The initial imprint appears to be excellent. However, as the ink moved up through the transfer paper, it left a faint shadow on the Teflon.

Nikon D3 wouldn’t capture the shadow since it was so faint, so I had to use a Bic pen to get the shot. It’s too faint to shoot, but not so faint that it will destroy the next shirt.

As per Murphy’s Law, I arranged the Teflon sheet so that the shadow was outside the second shirt’s planned imprint region. I had a custom imprinted, yet completely useless shirt after 400 degrees and 40 seconds. Salute to Science!

The partial shadow of the top of the imprint, marked by the Bic shadow pointer-outer, can be seen a few inches above where the picture is meant to begin.

So what can you do if you can’t use a Teflon sheet for sublimation? Would you like a beautiful, clean sheet of copy paper? Just make sure it thoroughly covers the transfer paper to prevent ink from migrating to the heating element’s bottom.

For further security, use two sheets. They’re inexpensive and may be discarded with the transfer paper after the shirt is finished.

With CAD heat transfer letters and normal inkjet transfers, your Teflon sheet is very important, but not with dye sublimation, which doesn’t need it.


Finally, while utilizing a heat press, Teflon sheets are necessary to protect your cloth.

It also helps to find printing mistakes when thick ink deposits or fibers are used.
