Sublimation is a type of tape people use to transfer images to fabric, and different material types. Usually, some common applications of the tape include creating unique apparel designs, custom labels, and customized clothes. 

Most brands use heat-resistant material – making them perfect for creating high-end designs. The tape is also easy to cut into various sizes or shapes. It’s then exposed to a heat press or iron transfer, which sets the image on the material.

The result is that the image permanently embeds onto the material and will resist issues like fading. Sublimation tape is also easy to use, but many people still face the marks issue.

The issue of sublimation tape leaving marks on shirts is a common problem. It occurs because the adhesive tape might not suit your shirt’s fabric. Thus, this causes it to leave a sticky residue that can be difficult to remove. 

What are the Causes of Sublimation Tape Leaving Marks on Shirt

Here are the common causes of sublimation tape leaving marks on shirt:

Cause #1. Heat Transfer 

Excessive heat is a leading cause of sublimation tape leaving marks on your shirts. Why is that? Well, excessive heat can occur due to various reasons. 

These include lack of experience, the wrong temperature settings, or using a worn-out press. Leaving the press on a single section of the shirt for excessive periods can also leave tape marks on your shirt.

The excessive heat causes the tape to stick to the fabric, which produces a visible mark upon removal. 

Cause #2. Poor Quality Tape 

Sublimation tape consists of an adhesive you can use for heat transfer printing. Users have to expose the tape to some heat, which helps leave marks on the printed shirt. 

Poor-quality tape can cause sublimation tape to leave marks on your shirt. And there are various reasons this can happen.

One is because the adhesive may not be strong enough to withstand heat from the transfer procedure. It can also cause the tape to stick to the fabric, producing marks on your shirt.

Another reason is that the adhesive won’t work well with the fabric – which eventually causes the marks issue. The tape might also lack sufficient heat-resistant functions, thus causing it to melt easily upon exposure to heat.

Cause #3. Improper Method of Application 

Using sublimation tapes incorrectly can also lead to the marks issue. That is because making any major mishaps during the application process will compromise the quality of your designs.

You must also use the correct tape type. Usually, shirt makers often use vinyl tapes for synthetic fabrics. However, paper tapes work well for natural fabrics. Pressing the sublimation tape firmly on your fabric is also important.

That is because it helps improve the design’s final finish quality.

Tip #2. Adjust Temperature and Time Settings 

Another crucial aspect of sublimation tape is maintaining the right temperature and time settings. Doing this will help reduce the chances of marks appearing on your shirt.

Usually, the best temperature for pressing sublimation tape averages between 350 to 380 degrees Fahrenheit. The best time for pressing sublimation tape is 10 to 20 seconds.

So, you can see why getting the metrics right is crucial for the quality of shirt designs. You also have various other alternatives for regulating the heat. 

Tip #3. Use Protective Sheets 

A good example is Teflon Sheet or Parchment paper to help with sublimation tape leaving marks on the shirt. You can set the protective sheets between the shirt and tape. Doing this will stop the tape from leaving any residue on your shirt. 

Removing the tape carefully is also important when using tape on your shirt. You must pull of the tape slowly to prevent any damage to the shirt.
