1. Cutting Conditions

Whether your vinyl is just cuttable or printable the manufacturer cutting blade and force setting for your cutter.  Typically, the blades are either 45 degrees or 60 degrees.  The force setting is important because it insures a good clean cut.  Force is expressed in Grams of Force (gf.). It is important to follow the Cutter Manufactures specifications to insure a clean cut on the vinyl and avoidance of chopping up the Cutter Strip. 

2. Wrong Temperature Settings

One of the most common mistakes when working with heat transfer vinyl is using the wrong temperature settings on your heat press machine. Incorrect temperature can lead to a variety of issues, such as poor adhesion or even melting of the vinyl material.

To avoid these problems, it's essential to understand and follow the manufacturer's recommended temperature settings for each specific type of heat transfer vinyl you're working with. Different materials may require different temperatures for optimal results.

  • Manufacturer Guidelines: Always refer to the guidelines provided by your heat transfer vinyl manufacturer for accurate temperature settings.
  • Type of Vinyl: Be aware that different types of vinyl (such as glitter, flock, or metallic) may have unique temperature requirements compared to standard HTV materials.
  • Fabric Compatibility: Keep in mind that certain fabrics might be sensitive to high temperatures and could get damaged during pressing. Make sure you know how much heat your chosen fabric can withstand before proceeding with application.
    Before using on a larger scale, try out the process with some scrap fabric to ensure it's set up correctly. This will help ensure that you've got everything set up correctly before moving onto larger-scale production runs at your print shop. Joto Imaging Supplies offers an extensive guide on selecting and applying various types of heat transfer vinyl which can help eliminate any confusion surrounding proper usage techniques and equipment settings.

In addition to following manufacturer recommendations regarding appropriate temperatures, also make sure that your heating element within the press is functioning properly and providing consistent coverage across its surface area. Uneven heating can lead to inconsistent results and wasted materials.

Wrong temperature settings can lead to poor quality transfers, so it's important to ensure that the correct heat setting is used for each material. Moving on, another common mistake with heat transfer vinyl is poor pressure application.

3. Poor Pressure Application

Applying the right amount of pressure when heat pressing is crucial for successful heat transfer vinyl (HTV) application. Too much or too little pressure can cause the vinyl to not adhere properly, leading to issues such as bubbling up or peeling off after application. In this section, we will discuss some common mistakes related to poor pressure application and how you can avoid them in your small and medium print shops.

A. Insufficient Pressure

When there's not enough pressure applied during the heat pressing process, it may result in an incomplete bond between the HTV and the fabric. This could lead to problems like peeling or cracking of the design after washing or even immediately after applying it on garments. To ensure proper adhesion, make sure that you're using a high-quality Heat Press machine with adjustable pressure settings and follow manufacturer recommendations for optimal results.

  • Tips:
    • Always test your equipment before starting production runs and first thing every morning
    • Regularly check if any adjustments are needed due to wear and tear on your machine components.

B. Excessive Pressure

On the other hand, applying too much pressure during heat pressing can also be problematic for HTV applications as it may cause bubbles or wrinkles within your design while transferring onto fabrics - especially those made from delicate materials like polyester blends which are more susceptible to scorch marks under high temperatures.


To prevent pressure from becoming an issue in your HTV application:

  1. Maintain consistent downward force throughout the entire duration of the heating cycle by ensuring that the platen evenly distributes weight across the entire surface area.
  2. You can use a dollar bill inserted on each side of the heated platen to gauge your pressure.  Simply test both sides and the front and back of the machine.  If the bill comes out easily after the machine platen has been lowered, then increase the pressure.
  3. Be mindful of any changes in fabric thickness or density that could impact pressure requirements (e.g., plackets and seams, zippers, or buttons).  

By paying close attention to the amount of pressure applied during heat pressing and making necessary adjustments based on your specific HTV material and garment type, you can avoid common issues related to poor adhesion and ensure a high-quality final product for your customers. Remember that practice makes perfect - so don't be afraid to experiment with different settings until you find what works best for your unique needs atJoto Imaging Supplies.

Poor pressure application can lead to improper adhesion and a subpar result. To ensure that your heat transfer vinyl adhere correctly, it is important to understand the correct time settings for each type of material.

Common Mistakes with Heat Transfer Vinyls

Heat Transfer Vinyl (HTV) is a popular material used to create custom designs on fabrics. However, there are some common mistakes that can occur during the application process. Here are some of the most frequent issues and how to avoid them:

Using the Wrong Materials

One of the most common mistakes with heat transfer vinyl is using the wrong materials. HTV is designed to work with certain fabrics, and using the wrong type can result in poor adhesion or even damage to the garment. Always check the manufacturer's recommendations before starting your project.

Dye Migration

Dye migration is another common issue with heat transfer vinyl. This occurs when the dye from the fabric bleeds through the vinyl, resulting in a discolored or distorted design. To prevent this, use a vinyl that is specifically designed to resist dye migration, and avoid using extreme heat or pressure during the application process.

Extreme Heat

Using too much heat can also cause problems with HTV. If the temperature is too high, the vinyl can melt or become distorted, ruining your design. Always follow the manufacturer's recommended temperature settings and use a heat press or iron with a digital temperature control to ensure accuracy.

Dark Fabrics

When working with dark fabrics, it's important to choose the right type of Vinyl. Some HTV materials are designed specifically for use on dark fabrics, while others are better suited for lighter colors. Using the wrong type can result in poor adhesion or a design that is difficult to see.

Warm Water

After applying the first HTV design, it's important, to ensure the design stays in place that you do a wash test before you complete the entire order.  Additionally, you need to recommend the proper washing instructions to the customer.   However, using very hot water can cause the vinyl to prematurely peel or crack over time. You want to always recommend the use of warm or cold water and avoid using fabric softeners or bleach.

Fully Adhered

Finally, make sure your vinyl is fully adhered to the fabric before removing the carrier sheet. If the vinyl is not sticking properly, use a heat press or iron to apply additional pressure. You can also try using silicone paper to protect the vinyl during the application process.


By avoiding these common mistakes, you can ensure that your heat transfer vinyl projects turn out perfectly every time and your customer will come back. 


When it comes to using heat transfer vinyl, there are several common mistakes that can easily be made. From incorrect temperature, time, and pressure settings to improper weeding techniques, these mistakes can lead to wasted materials and unsatisfactory results.


To ensure successful results, it is essential to be precise and accurate when performing each step of the process. This includes setting the right temperature and time settings for your vinyl type, applying the recommended pressure evenly across the design, and carefully weeding away excess material.
