YouTube Tutorial for heat transferring onto a shirt

Why should I heat transfer a shirt myself?

Of course, you can have your desired T-shirt printed online or in a shop nearby. But why not just print on your T-shirt yourself and conjure up a truly unique piece? With a small, affordable plotter, you can already implement great small lettering and motifs.

Plotting seems complicated to beginners at first. But once you have understood how it works, it is quite "simple." By the way, with the instructions in this blog post, you can also print on sweaters, shirts, jackets, and much more. The steps for printing on textiles are always very similar.

Do you already own a plotter and want to heat transfer your individual T-shirt now? I will give you information and tips so that you can get started right away.

So let's go. I'll show you how it works.

What can I plot onto a T-shirt?

A beautiful lettering or an image with clear lines can be plotted perfectly onto a shirt or sweatshirt. A face in line art technique can also be plotted onto a T-shirt. A plotter actually cuts or draws the lines of a graphic.

Depending on the model, you can use different file formats. SVG files are best suited. Every plotter can process these. Some plotters can also process DXF, JPG, and PNG.

Tip: Pixel files can also be converted into a vector graphic. I like to use the free program Inkscape for this.

There is also printable heat transfer vinyl, which even allows you to print photos and images onto a T-shirt. Read more about this in my post "Which transfer vinyl for what?"

Heat transferring a T-shirt: Which film?

To heat transfer a T-shirt, you should use a heat transfer vinyl. Here you can see which film is best suited for which textile. To help you find the right product group immediately, we have linked the types of films.

Which step do I start with when plotting?

To begin with, you should first think about what you want to plot onto your T-shirt. And what effect you want your self-made T-shirt plot to have.

You can either use a free file from your software or buy a suitable file online. If you haven't found anything suitable, you can also easily create a file yourself.

Be sure to pay attention to the usage rights; for commercial use, you need a license for the file.

Are you unsure which film is suitable for your T-shirt? Then take a look at my post on the topic Buying transfer vinyl.

Cutting the motif with the plotter

Once you have decided on a motif and a film color, it really starts. First, we take care of plotting the motif. That's half the battle. Let's take a closer look at the textile film we need to print on the shirt.

Then you fix the film with the carrier sheet facing down on the cutting mat so that no air bubbles form under the film. I like to use a roller or a squeegee for this.
Now insert the cutting mat.

The cutting mat has an arrow at the top for marking.

Brother plotters have a great feature: the ability to scan the cutting mat. This is especially handy for vinyl scraps.

You can then precisely position your design on the display and make use of even the smallest remnants.

Depending on your plotter, you may still need to adjust a few settings such as cutting depth, cutting pressure, or half-cut on/off. With Brother, this is very simple to do via the tool icon on the display.

I have a Brother and I select the half-cut setting so that my iron-on vinyl gets cut, but the carrier sheet does not. The Brother ScanNCut DX handles the rest automatically.

And you're ready to go. Your plotter will cut the lines along the coordinates.

Tip: Do a test cut. An @ sign works well for this, as it allows you to easily see if the pressure and cutting depth are set correctly.

Weeding the design

Once your plotter has cut all the lines, remove the vinyl from the cutting mat.

Tip: When removing the vinyl from the cutting mat, always peel the mat away from the vinyl rather than the other way around; otherwise, the vinyl will curl up and your design could be damaged.

Now begin to weed all the internal spaces so that these aren't pressed onto your T-shirt.

You can use a weeding hook or tweezers for this.

Sometimes it happens that the plotter didn't cut every line completely. In this case, you can touch up the lines with a scalpel. If that happens, it’s advisable to adjust your cutting settings next time.

I recommend a small desk trash can for your vinyl scraps; otherwise, you'll end up with little bits of vinyl everywhere. It has happened to me before that a tiny scrap sneaked onto my T-shirt.

I will explain what you can do in such a situation at the end of this post.

Positioning the plotter design correctly

Before you position your design on your T-shirt, you should go over the desired area once with a lint roller.

This will prevent you from trapping any small bits of lint or hair in your design.

Preheat the T-shirt once with your iron or heat press; this evaporates any residual moisture remaining from washing. Now place your design with the vinyl side down. The carrier sheet will be facing up.

Be careful not to shift the design.

Tip: If you want to position your design exactly in the center, fold your T-shirt in half and press it briefly. This will create a crease you can use as a guide.

Mark the center of your design as well.

Pressing the design

Follow the manufacturer's instructions regarding transfer temperature, time, pressure, and removal of the carrier sheet (warm or cold).

If you are working with an iron, the steam function must definitely be turned off. Heat and pressure are important here. Place your T-shirt on a hard surface and apply sufficient pressure. A table or the floor works best.

Do not move the iron back and forth, as this could distort the design. Simply lift the iron carefully and place it down in a new spot after a few seconds. Always take a short break so you don't overheat the vinyl. Repeat this until everything is securely attached.

Now peel off the carrier sheet very carefully. If the vinyl should lift at any point, simply iron over it again.

If you are making a multi-colored plot, you work in layers.

You should make sure that the lines align perfectly with each other.

Finally, place the protective sheet/parchment paper over your design and press or iron again with plenty of pressure to fix your design. Here too, you should not slide the iron, but rather lift and place it carefully.

And it's done :)

How long and at what temperature should the finished plot be pressed?

You can apply the prepared plot to your textile using either an iron or a transfer press. How hot and how long the plot needs to be pressed depends on the specific vinyl and the fabric you are working with.

The instructions for applying the plot are always provided on the vinyl packaging. To keep your finished design looking good for a long time, you should really follow these usage guidelines. It helps to keep the vinyl in its original packaging so that the ironing times and temperatures are always at hand.

How does removing heat transfer vinyl and plots work?

Did you follow everything, but something still went wrong?

Don't worry, your T-shirt doesn't have to go straight to the bin. I'll share a tip here that I wish I'd known as a beginner: removing heat transfer vinyl.

You don't have to laboriously scratch the vinyl off the fabric with tweezers like I did.

Instead, here is how it's done: Warm up your plot from the back of the fabric with an iron and peel off the vinyl using tweezers or a weeding hook.

Depending on the vinyl, there might be slight adhesive residue left over, which you can simply cover with a new plot.

How do I care for my new favorite shirt?

A plot on a textile can last for years with proper care. I'll give you a few tips in this section so you can enjoy your new favorite shirt for a long time.

Pro tip: I've had good results pressing onto unwashed textiles, as washing can roughen the fibers of the fabric. This can sometimes cause the design to peel off again after a few washes.

My care tips:

• After pressing, you should not wash the T-shirt for 24 hours, as the vinyl continues to bond with the fabric during that time.
• Wash at a maximum of 40 degrees.
• Do not use fabric softener.
• Wash inside out.
• Do not tumble dry.
• Use a pressing cloth when ironing if necessary.

And the best part: I am making my free Disco lettering available to you and am excited to see what you create with it. By choosing different vinyls and materials, every plot becomes unique. For example, I added an offset in my plotter software to create a great contrast with the glitter vinyl.

Of course, other textiles can also be printed this way. Show me your results on Instagram and tag me @art.und.ich and @sewsimple.de :)

Happy plotting, Ria & Sabine
