Heat Press Basics! What is a heat press AND how does a heat press work?
I remember, years ago, when I first heard about heat press machines. Well actually, I saw a picture of one, and thought ‘what on earth is that?’ Little did I know that they would soon become a significant part of my life!
In this short but sweet post, I’ll share with you the answers to the following questions:
While you might not know exactly what a heat press machine is or does, you have surely seen what they make.
You will have seen t-shirts and hoodies with designs on them, or sports jerseys with names and numbers. Many of the designs, images, or text that you see on clothing, have been applied with a heat press.
A heat press machine is used to apply heat transfers (there are different types) onto garments and other surfaces using time, temperature and pressure.
Siser EasyWeed is the best heat transfer vinyl. It is easily applied with a heat press or an iron, and looks great. It’s a very thin and flexible vinyl so it doesn’t look like it is sitting on top of your t-shirt, like some of the cheap HTV. It looks like it really meant to be on your garment, if you know what I mean!
3. How Does A Heat Press Work?
Heat press machines have two plates, or platens, as they are more often called. The top platen heats up, and is called the heat platen. Once the machine is turned on the heat platen will heat up to the set temperature.
Most, if not all, heat press machines have a digital display on which you can set the time and temperature. Some more expensive machines will also allow you to set the pressure digitally.
The time range for most t-shirt presses is 0 – 999 seconds. Thoough no one is ever going to do a press for 999 seconds (16 minutes)! Most heat transfers only need 10 – 20 seconds to complete.
Most machines have a temperature range of 0 – 500° F. This is more than enough to perfectly apply all heat transfers onto t-shirts (and other garments). A temperature higher than 500° F would likely burn or melt your transfers and t-shirts!
Pressure is set on most machines by turning a knob. This knob will be situated either on top of the control box at the back (unless it is set digitally).
Pressure is described in terms of lightness to hardness. For example, Siser EasyWeed is pressed at a medium pressure, while EasyWeed Extra is pressed at a light-medium pressure.
