Starting a small custom printing business sounds like a big step, but in reality, it’s one of the most accessible side hustles you can start today—especially if you’re focusing on products like T-shirts and mugs. These are everyday items with massive demand, and with the right setup, you can go from zero to your first sale faster than you’d expect.
One of the most important decisions you’ll make is choosing the right heat press machine. Get this right, and everything else becomes easier. Get it wrong, and you’ll end up frustrated, wasting materials, and questioning the whole idea. So let’s break it down in a practical, beginner-friendly way.
Understanding What You Actually Need
Before diving into machine types, it’s worth getting clear on one thing: your product decides your machine—not the other way around.
If your goal is to print custom T-shirts, you’ll need a flat heat press.
If you’re planning to sell mugs, you’ll need a mug press.Simple, right? But here’s where beginners often get stuck—they try to find a “do-it-all” machine without understanding trade-offs.
Yes, combo machines exist. But if you’re just starting and care about ease of use, consistency, and value for money, dedicated machines are usually the smarter move.
Choosing a Heat Press for T-Shirts
Let’s start with T-shirts, because this is where most people begin.
What to Look For
A good T-shirt heat press for beginners should be:
- Clamshell or swing-away design (clamshell is more compact and beginner-friendly)
- Platen size around 12" x 15" or 15" x 15" (big enough for most designs)
- Even heat distribution (this matters more than you think)
- Digital time and temperature control
- Medium pressure adjustment
You don’t need anything fancy. In fact, simpler is often better when you’re learning.
Why T-Shirts Are a Great Starting Point
- Huge market
- Low-cost blanks
- Fast production time
- Easy to customise for trends, niches, or local markets
You can literally start selling after a few practice runs.
Basic Steps to Use a T-Shirt Heat Press
- Preheat the machine (usually around 160–180°C, depending on material)
- Place the T-shirt on the platen and smooth out wrinkles
- Pre-press for 3–5 seconds to remove moisture
- Position your transfer (HTV or sublimation print)
- Press for 10–15 seconds with medium pressure
- Peel (hot or cold, depending on material)
- Optional: Second press for durability
That’s it. Once you’ve done it a few times, it becomes second nature.
Common Mistakes to Avoid
- Using uneven pressure → leads to poor adhesion
- Skipping pre-press → causes bubbling or fading
- Guessing temperature → always follow material guidelines
Choosing a Heat Press for Mugs
Now let’s talk about mugs—a slightly different game, but just as profitable.
What to Look For
A beginner-friendly mug press should have:
- Adjustable heating element (to fit different mug sizes)
- Consistent wrap-around heat
- Digital timer and temperature control
- Easy pressure adjustment knob
Unlike T-shirts, mugs require more precision. But don’t worry—it’s very learnable.
Why Mugs Are Worth It
- High perceived value (you can sell for more)
- Great for gifts, seasonal products, and custom orders
- Less competition compared to T-shirts in some niches
Also, mugs are perfect for platforms like Etsy or local gifting businesses.
Basic Steps to Use a Mug Press
- Print your design using sublimation ink
- Wrap it tightly around the mug
- Secure with heat-resistant tape
- Preheat the mug press (around 180–200°C)
- Insert the mug and apply pressure
- Press for 180–300 seconds
- Remove carefully (it will be hot!)
- Cool down before removing paper
Common Mistakes to Avoid
- Loose paper wrapping → blurry prints
- Uneven pressure → faded areas
- Overheating → dull or burnt colours
Should You Buy Both Machines?
If your budget allows, yes. But if you’re starting small:
-> Start with T-shirts (lower risk, faster turnaround)
-> Add mugs later once you get ordersThis way, you don’t overwhelm yourself.
A Quick Word on Budget
You don’t need to spend a fortune to get started.
A solid beginner setup usually includes:
- One heat press machine
- Basic materials (vinyl or sublimation paper)
- Blank products (T-shirts or mugs)
-> You can realistically start with a few hundred pounds.
Beginner FAQs
1. Do I need design skills to start?
Not really. Tools like Canva make it super easy. You can start with simple text designs or trending phrases. Over time, your skills will naturally improve.
2. Is sublimation better than vinyl?
It depends on your product.
- Sublimation → best for mugs and polyester fabrics
- HTV (vinyl) → more flexible, works on cotton
For beginners, many start with vinyl for T-shirts and sublimation for mugs.
3. How long does it take to make one product?
- T-shirt: 2–5 minutes
- Mug: 5–8 minutes
Once you get into a rhythm, you can produce quite efficiently—even from home.
Final Thoughts: Is This Business Worth It in the UK?
Let’s be honest—there are a lot of side hustle ideas out there. Some sound great on paper but are hard to execute. This isn’t one of them.
In the UK, custom printing is actually a very practical business to start:
- Low startup cost
- No need for a physical shop
- Strong demand (events, gifts, small brands, local businesses)
- Fast turnaround and cash flow
You’re not trying to build a massive brand on day one. You’re simply creating products people already want—with a personal touch.
And that’s where the opportunity lies.
If you keep things simple, choose the right machine, and focus on learning step by step, this can go from a small side project to a steady income stream faster than you might expect.
Sometimes the best business ideas aren’t the most complicated ones—they’re the ones you can actually start.
