Heat Transfer Vinyl
Heat transfer vinyl (HTV) is a popular and one of the simplest methods for stylizing apparel and other materials. Understandably, people have a ton of questions regarding its use and applications. They are also interested in knowing how it’s different from other standard vinyl on the market.
So, if you’re a DIYer, hobbyist, or someone planning to step into the HTV market, this blog is for you. You will find detailed responses to common user queries on the use of HTV.
When Cutting Heat Transfer Vinyl Which Side Goes Down?
If you’ve looked at a heat transfer vinyl sheet, you may notice it has two sides: a shiny one and a slightly less shiny one (matte). The shiny side is the carrier, which is peeled off after the heat transfer, while the matte side is the actual vinyl. When cutting HTV with a vinyl cutter like the xTool M1 Ultra, the shiny side faces the mat (goes down), and the matte side faces the blade, so it can be cut.
Do I Need to Mirror the Image for Cutting HTV?
Yes, you need to mirror the image when cutting HTV. The reason is simple: after cutting the HTV from the top side (matte side), it’s flipped onto the shirt, and heat is applied through the clear carrier film. Mirroring the image cancels out the flipping effect, giving you the correct orientation.
Is Heat Transfer Vinyl the Same as Iron on Vinyl?
Yes, technically, heat transfer vinyl and iron-on vinyl are the same, and the terms are often used interchangeably in the industry. However, I believe there’s slight distinction between two.
HTV is more of a general term for all types of vinyl sheets and designs that require a heat press for application. It’s like a raw vinyl sheet that can be cut and shaped into designs. In contrast, iron-on vinyl generally refers to small, premade designs – such as cartoon characters or motifs – that can be applied with a household iron.
How to Iron on Layers of HTV?
Layering refers to the process of creating a multi-coloured design using HTV. For that, you should carefully align all the layers once before heat transfer and plan their order of application –starting with the outline, followed by the second design layer, and then the third. You may use tape to ensure the vinyl doesn’t moving during the heat transfer.
Do You Need Transfer Tape for HTV?
No, transfer tape isn’t necessary for HTV. Transfer tape is mostly used for self-adhesive vinyl, which has a sticky back, especially when working on lettering designs. After cutting, the transfer tape picks up the design and moves it onto surfaces like mugs. Since HTV is heat-activated and already has carrier sheet, transfer tape isn’t required.
Do You Have to Use Parchment Paper for Heat transfer Vinyl?
Yes, you need parchment paper or butcher paper to place between the HTV and the heat press to prevent direct contact. Because direct contact with the heat press can melt or warp the vinyl. Parchment paper, with its silicone coating, is non-stick and ensures even heat distribution during application.
What Temperature and How Long to Press HTV?
The heat press settings depend on the type of heat transfer vinyl being used and the fabric it’s applied to. For applying solid HTV on cotton with the xTool heat press, we recommend setting the temperature to 330°F (165°C), the time to 35 seconds, and using intermediate pressure at 20kg.

Is HTV Hot or Cool Peel?
Hot peel means vinyl needs to be immediately removed after pressing whereas cool peel requires waiting for the vinyl to cool down. HTV can be either hot peel or cool peel, depending on the type and manufacturer. The specific type is explicitly mentioned on the HTV packaging.
What Fabric is Best for HTV?
HTV works on almost all fabrics, including natural ones like cotton and synthetic ones like nylon and polyester. However, it provides the best results on 100% cotton materials because they can sustain heat, are breathable, and have a smooth surface that bonds well with the vinyl.
What Materials Can You Use HTV on?
HTV works on a variety of fabrics and solid surfaces. Among fabrics, it is compatible with polyester, cotton, blends, nylon, and denim. Examples of hard surfaces include ceramics, wood, glass, acrylic, and metal. Other compatible surfaces include leather and cardstock.
Why Is My HTV Not Sticking?
HTV adheres properly when the correct combination of heat, pressure, and time is applied. If you’re not using enough heat or pressure, or if you’re transferring too quickly, the vinyl may not stick. So, it’s best to follow the recommended settings for your material and HTV type.
Why Does My HTV Peel after Washing?
There could be several reasons for peeling. To prevent this in the future, follow these tips:
- Apply the correct temperature during heat transfer.
- Wash shirts inside out.
- Wait at least 24 hours before washing HTV-applied shirts.
How Long Does HTV Last on Shirts?
The lifespan of HTV depends on the fabric and vinyl type. Generally, HTV designs last for 30 to 50 washes before they begin to crack. You can slightly extend their lifespan by washing shirts inside out and ironing them the same way.
Can You Print on Heat Transfer Vinyl?
Yes, printable heat transfer vinyl is available. It works like a blank canvas that can be printed with colourful digital designs using an inkjet printer. The rest of the application process is the same as that of regular HTV.
Can You Use Heat Transfer Vinyl on Tumblers?
Yes, you can use heat transfer vinyl on cylindrical objects like tumblers or mugs. For transferring, you’ll need a mini heat press or iron to apply heat from the top. Also, mug or tumbler heat presses are available for this dedicated purpose. Another option is self-adhesive vinyl, which sticks without requiring heat.
How to Tell the Difference between HTV and Permanent Vinyl?
Permanent vinyl, also called self-adhesive vinyl, has a sticky backing that allows it to be peeled and applied like a sticker. HTV, on the other hand, requires heat for application.
To differentiate, try peeling the carrier sheet from the corner – if it’s sticky, it’s permanent vinyl. Also, designs don’t need to be mirrored when cutting permanent vinyl, unlike HTV.
