Do You Know How Does A Heat Press Work?

Heat printing, also known as heat transfer printing, is the process of applying heat-applied materials to various items (i.e., substrates) with a heat press. Heat-applied materials contain a heat-sensitive adhesive on one side; when heat is applied by a heat press to the material, the material adheres to the substrate to which it is being applied.Now,let's to learn more information about heat press.

1.What is a Heat Press Machine?

A heat press machine is essentially an iron press machine which enables you to transfer creative designs by applying pressure and heat to different materials, such as t-shirts and more. They come in a variety of sizes, depending on the size of the garment that you wish to work with. 


2. How Does A Heat Press Work?

Step 1 – Adjust Temperature:
Time to set your temperature that is required to heat press your garment. Scan over the instructions that are printed on the transfer paper to find the accurate temperature that’s best.

  • Turn the thermostat knob in a clockwise direction until you see the red heating light. 
  • Wait for your machine to heat up to your required temperature.
  • A flashing light will indicate that the heat press is adequately heated.
  • At this point, you should turn the knob counterclockwise until the flashed light turns off.

Don’t be alarmed when the light switches on and off during your heat press.  It is an indication that your machine is regulating your desired temperature.

Step 2 – Set Up your Tee & Design:

Open the heat press by lifting the front handle of the machine. If you bought a clamshell machine, your upper platen will move upwards.  If you bought a swing-away press, your upper platen will swing out to the side.

  • Pop your garment on the heat press. The side that is being printed on should be facing upwards.
  • Close the lid for a few seconds to warm up the material.  This step will remove creases and moisture which will result in a better press.
  • Open the lid and lay the transfer paper face down on the garment.
  • Bring the handle down such that it locks firmly in place.

Remove the peel off of the transfer paper to reveal the awesome printed graphic on your garment.


Step 3 -Pressure:

You might need to adjust the pressure on the machine. 

The amount of pressure that needs to be applied is dependent on the type and thickness of the material of the item. 

For example, a garment that is 100% polyester requires less pressure than other materials due to the fact that the fabric is so smooth. 

  • On cheaper machines: Turning the pressure adjusting-knob clockwise so that you can correctly increase the pressure. (By turning the knob counterclockwise you can decrease the amount of pressure).  
  • On professional machines: More expensive machines have a really handy pressure gauge. A pressure gauge will typically have a range from one to nine. For light pressure, choose a setting from 1-3. For medium pressure trial out setting 4-6 and for heavy pressure choose from 7-9.

Pressure is probably the trickiest of the heat pressing elements to master.  You might feel more comfortable doing a test run to find the best setting for your fabric.

Step 4 – Time:

  • Press the start button to start the heat press timer (information about the time required can be found on the transfer paper packet instructions). 
  • When the timer alarm goes off, simply lift the handle to open the machine. (simply press the timer to reset it for the next press)

Check your transfer paper instructions to see whether your paper is a hot-peel (peel while the design is still hot) or a cold-peel (leave the design to cool down before peeling)

3.The Importance of Correct Pressure

The right amount of pressure is incredibly important to the quality of the finished product. Too much pressure and you can push the ink too far into the fabric, which will result in a dull color and vibrancy of your completed design.

Too little pressure could lead to the heat transfer not adhering properly.  You might also find that the fibers on the shirt might stick through your design, which will lead to a fuzzy looking graphic.
The right amount of pressure is crucial in order to allow the inks to cure and to securely link.  This will ensure that the bond will outlast hundreds of washes and will outlast the life of the t-shirt. 

4.Which Transfer Paper to Choose

   You will need to ensure that you choose the right transfer paper for both your printer as well as for your design. Most transfer papers are for inkjet printers.
   If you are printing via a different method, you will need to ensure that the transfer paper is compatible with your printer. It is also important to think about whether you will be working on a white, black or color tee.
   Again, as with many other aspects of heat pressing, you will most likely have to go through a process of trial and error to find the type of paper that you love working with the most.
