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. 

You can also get attachments to make life of printing onto mugs or caps easier.

How to Use a Heat Press Machine Step-by-Step Guide

How does a heat press work?  The formula for applying heat transfer to a tee or item is temperature, time, and pressure.

Find some helpful heat press machine instructions on how to conquer the trio in order to produce a smashing printed tee time and time again.

Ultimately the use and setup is pretty straightforward. The step-by-step guide below will teach you how to use a heat press machine.

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.

Heat Pressing a Tshirt

  • 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.

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). 

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

Helpful Tips and Trick on How to Heat Press an Item

Whilst the instructions above are simple and easy to follow, you might find that you are still struggling to get that perfect printed graphic.  Heat pressing is truly about trial and error and before long, you will find that you are an expert at it.

Below we share some of our most nifty tips and tricks to help ensure that you first press goes as smooth as possible.

Where to get your Graphic

You can either find an SVG file download online, or you might prefer to design your own graphic.

You have two main options of how to create your graphic.  The easiest, in my opinion, is to do this with the use of a vinyl cutting machine.  You can simply grab an SVG download and print and cut it out with the cutter.  To learn more about these machines, why not browse through our vinyl cutting machine reviews here.t shirt heat pressing

The second option is by printing a design, that you created through software like Corel or Adobe Illustrator, by using an inkjet printer onto transfer paper. You can find instructions on how to print on vinyl here.

Note: Don’t forget to flip your artwork horizontally using your design software.

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.

We love both Avery T-shirt Transfers for Inkjet Printers and Jet Pro Soft Stretch for light colored 100% cotton/poly blend fabrics.

Which Fabric to Choose

You can’t just grab any t-shirt and expect to heat press on it.  Do stay away from synthetic material as well as thin material as they can easily melt.  The most popular types of fabric for t-shirt printing include cotton & polyester. But you can also use nylon, spandex and Lycra.

Test Prints

We highly recommend that you do a test print before you adhere your larger design.  Simply cut a t-shirt into smaller pieces, create a small design on the transfer paper and give it a test run to ensure that temperature, timing and pressure is properly set.

Another good habit to get into is to print your design out on paper.  Roughly cut the design out and lay it down on your t-shirt to ensure that the design is the correct size and that it doesn’t run over any seams, buttons or pockets.

How to Get a Straight Print

It is crucial that you ensure that your shirt if laid down straight onto your platen.  Nobody likes a crooked graphic!  Tricks to ensure that you design is straight includes using grides, lasers or simple rulers. Whatever method you choose to use, do ensure you take the time to position your design before you apply the heat.

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. To learn more about pressure, click here.

As a newbie, you can feel quite stressed out about finding the right setting for your shirt.  We recommend that you start out with a light pressure for cotton, polyester and nylon fabrics.  Before long, you will know exactly what pressure is required for any type of item.

Trial and error might be frustrating, but it is the only way to learn in order to become an expert at t-shirt design.

Caring for Heat-Pressed Tees

  1. Turn them inside out before washing

  3. Avoid using harsh detergents

 

Heat pressing is a pretty addictive craft!  Before long you will find that you have heat pressed graphics onto anything in sight – cups, plates, umbrellas, shopping bags and more!

Others might even find that once they turn into an expert that they would like to start their own business to sell items with their own unique art, branding and/or logos.
