The heat press is a versatile and efficient tool that has revolutionized the world of personalized clothing and textile printing. Its ease of use, coupled with its accuracy and cost-effectiveness, makes it a compelling choice for many. But how does the heat press work? What are the criteria to respect? What budget should we plan to get one?
The heat press: an essential tool in the world of printing
The heat press (or transfer press) emerged in the 20th century. Initially, this technology was rudimentary, often involving manual methods of applying heat and pressure. In 1930, the first patent for a heat press was filed, but it was not until the late 1960s and early 1970s that the technology became more refined and commercially viable.
The advent of digital technology in the late 20th century revolutionized the heat press industry.
Indeed, today, modern machines are equipped with digital timers, temperature controls and pressure settings, making the process more precise and efficient. The heat press has evolved from a simple manual machine to a sophisticated piece of equipment capable of handling a variety of materials and complex designs in the printing world.
What is a heat press?
A heat press is a device used to apply pressure and heat to a material, usually for the transfer of a design or image onto that material.
This type of press is very common in the textile customization industry, including for techniques like DTF (Direct To Film).
How to use a heat press?
Using a heat press is relatively simple, but it requires careful attention to detail. PrintMyDTF explains precisely how to use it.
It is necessary to adjust the heat press to required temperature and pressure. For example, for cotton, set the temperature between 180 and 190 degrees. The transfer time must not exceed 10 seconds, and the pressure must be 3.5 bars.
Warning: the machine must be on a stable surface.

Then you can move on to the placement of the garment or textile. Place it on the bottom platen of the heat press. Make sure the fabric is smooth and wrinkle-free.
Position your heat transfer or vinyl design on the garment, making sure it is aligned correctly and lower the top platen onto the garment and start the timer. Heat and pressure will transfer the design to the material.
Once the timer goes off, lift the top plate and carefully peel off the transfer paper if using one. In case of forgetting or dirty press, you use a Teflon sheet (heat resistant) or baking paper to protect the textile. Finally, allow the garment to cool before handling it further.
Keep in mind that temperature, time, and pressure settings may vary depending on the type of material and design you are working with. Always refer to the instructions provided with your heat transfer or vinyl!
What are the particularities of the heat press?
The heat press has several unique characteristics. Let’s discover them together!
One of the most important advantages of the heat press is its versatility. This is because you can use it to transfer designs onto a wide range of materials, including fabric, ceramics and even wood. Compared to traditional methods like screen printing, hot pressing is much faster and ideal for small to medium production runs. In addition, they are equipped with digital controls that allow precise adjustments of temperature, time and pressure. This ensures consistent, high-quality results.
If you want to print detailed images, the heat press is ideal! It allows for high levels of customization, allowing you to easily create unique designs.
Finally, the heat press comes with safety features such as automatic shutdown and alarms to prevent overheating or other potential problems.
The different types of press
Depending on the type of project and specific needs, there are several types of heat presses that differ in their operation, use and cost.
They use electromagnetic fields and unlike hydraulic or pneumatic presses, electromagnetic presses generally operate more quietly.
However, electromagnetic presses have the disadvantage of not having precise pressure control, resulting in poor print quality.
They use compressed air, and automate the pressing process which allows for greater precision and uniformity compared to manual presses. Compressed air ensures uniform pressure distribution across the entire surface of the material, which is crucial for achieving high-quality results. In addition, depression control is constant and precise.
The cost of this press is high and requires a compressor which makes noise.
Generally simpler to use than their automatic or pneumatic counterparts. They are often recommended for beginners or small businesses. Manual presses are often smaller and lighter, making them easier to move and install in tight spaces.
The application of pressure must be done manually, which can be tiring during large batches. Additionally, manual control of pressure and temperature can cause variations in print quality.
Single-plate press VS two-plate press: what’s the difference?
Two types of presses exist: single-plate presses and two-plate presses. A single-platen press is often more suitable for beginners or small operations, while a two-platen press is more efficient for large-scale productions.
Single plate press
This type of press is generally easier to use and configure. It is ideal for beginners or for small-scale operations. Single-platen presses generally take up less space, which can be an advantage in tight spaces.
Additionally, they are often less expensive than two-platen presses, making them more accessible for smaller budgets.
In terms of production time, single-platen presses only allow one element to be worked at a time. This can slow down the production process if you have large quantities to print.
The main advantage of a two-plate press is efficiency. While one of the trays is being pressed, you can prepare the next item on the second tray. This enables a seamless, faster and more cost-effective workflow.
Please note: not all types of press come in two plates. For example, cap, cup or roller presses only come with a platen.
These presses are often used for higher production volumes. They are ideal for businesses that need to produce large quantities in a short time. Typically more expensive, these presses are considered an investment for businesses that have a high production volume.
However, two-platen presses take up more space due to their two-platen design. Make sure you have enough space in your workshop.
Some models allow the temperature and pressure of each tray to be adjusted independently, providing more flexibility for working with different materials or designs simultaneously.
There are also manual presses, which are easier to use. This is a viable option for those who are new to textile printing or have more modest production needs. They provide an excellent introduction to the basic principles of printing and are a good choice for small-scale projects.
Finally, there are different press sizes.
What size press to choose?
The little :
15 x 15 cm: Ideal for small projects like labels or pocket logos. 20 x 30 cm: Used for items like caps or sleeves. This type of press has a “curved” plate allowing the print to stick optimally!
The averages :
38 x 38 cm: A standard size for medium-sized projects, like t-shirts or canvas bags. 40 x 50 cm: Provides a little more space for larger designs or working with bulkier garments like hoodies.
The tall :
50 x 70 cm: Used for larger projects such as posters or banners.
80 x 100 cm: Ideal for industrial applications or for printing on large textiles such as sheets or curtains.
How much does a heat press cost?
The cost of a heat press can vary considerably depending on the type of press or its features.
Prices by type of press
Between 200 and 500 euros for entry-level models, and up to 2000 euros for professional models.
Cap or cup press
generally cheaper, around 100 to 300 euros.
These presses are more expensive and can range from 2000 to 10,000 euros or more.

Which heat press do we recommend in DTF?
It is important to have a heat press that can control the pressure. The ideal is therefore a heat press with compressed air. This type of heat press which uses compressed air has the particularity of applying uniform pressure to the material during the transfer process.
Tips for using a DTF heat press
- Ideally, the heat press pressure should be at 3.5 bars.
- Take into account that the edges of the heat press do not contain the same pressure as the middle. You should therefore not press close to the edge.
- For better print retention, we advise you to press the textile once for 10 seconds, unstack, and press again for 5 seconds. - You don't have a Teflon sheet? You can use baking paper to protect your textile!
- Avoid Chinese heat press brands. Generally, these are copies of European or American brands. Prefer to invest in a quality heat press!
- The temperature of a heat press will not be the same depending on the textile you are using. Be careful to choose the right temperature!
