7 Mistakes You’re Making with T-Shirt Printing Online (And How to Fix Them)

Ordering custom t-shirts online should be easy. You upload a logo, pick a colour, and wait for the delivery. But why do so many orders end up looking blurry, feeling cheap, or falling apart after one wash?
The truth? Most online platforms make it too easy to fail. They let you upload bad files. They don't warn you about fabric clashes. They just take your money and hit print.
At So Boss, we do things differently. We want your merch to look legendary. To help you get it right the first time, we’ve broken down the seven most common mistakes people make: and exactly how you can avoid them.
1. Are You Using "Internet Quality" Images?
This is the number one reason for bad prints. You find a logo on your website or pull an image from an email signature. It looks fine on your phone, so you upload it.
The result? A pixelated, blurry mess.
Screens display images at 72 DPI (dots per inch). Printing requires 300 DPI. When you blow up a small web image to fit a chest print, the printer has to "guess" where the pixels go. It usually guesses wrong.
The Fix: Use High-Resolution or Vector Files. Always aim for a high-res PNG or, better yet, a vector file (AI, EPS, or PDF). Vector files use mathematical paths instead of pixels. You can scale them to the size of a billboard and they will stay pin-sharp.
Check. Double-check. Print.

2. Are You Choosing the Wrong Print Method?
Not all printing is created equal. Many people assume "a print is a print," but choosing the wrong technology for your specific design can lead to a disaster.
The Breakdown:
DTG (Direct to Garment): This is our specialty for fast turnarounds. It’s like a giant inkjet printer for shirts. It’s perfect for detailed, multi-colour designs and single-item orders. (We offer same-day print and despatch for DTG if you order before our 10am Brisbane cutoff!)
DTF (Direct to Film): This is the king of durability and vibrancy. The design is printed onto a film and heat-pressed onto the garment. It’s incredible for hoodies, caps, and workwear where you need the colour to pop against darker fabrics. (DTF is available across our full range, though it doesn't fall under our same-day despatch guarantee).
Screen Printing: The old-school classic. It’s the best value for huge bulk runs but has a longer setup time. (Definitely not a same-day service).
The Fix: Match the Tech to the Need. If you need one shirt with a full-colour photo, go DTG. If you need 50 hoodies for a team, go DTF. If you aren't sure, ask our experts.

3. Why Are You Settling for "Sandpaper" Fabric?
A great design on a terrible shirt is still a terrible shirt. Many online printers use "budget" blanks to keep their prices low. These shirts shrink in the wash, itch the neck, and lose their shape after a week.
If the shirt feels like sandpaper, nobody is going to wear it. Your brand deserves better.
The Fix: Demand AS Colour Quality. We primarily use AS Colour for a reason. They are the gold standard for premium, retail-quality blanks. They are soft, pre-shrunk, and designed specifically to take ink well.
Invest in quality. Your customers will notice.
4. Is Your Design Too Complicated?
We get it. You want to include your logo, your website, your phone number, a list of services, and a QR code.
Stop.
T-shirts aren't flyers. If your design is too "busy," people won't look at it. Tiny text often gets lost in the weave of the fabric, and thin lines can disappear during the printing process.
The Fix: Keep it Bold and Simple. The best shirts have one clear focal point. High contrast is your friend: white ink on a black shirt or black ink on a Bone AS Colour Heavy Tee. Keep your text large enough to read from a few metres away.
Less is more.

5. Are You Playing "Size Roulette"?
Ordering 50 "Mediums" because you think it’s the "average" size is a recipe for leftover stock. Everyone has a different body type, and different brands fit differently.
The Fix: Know Your Audience. If you’re ordering for a gym, lean towards larger sizes. If it’s for a tech startup, a mix is usually safer. Always check the size charts on our product pages before you commit.
Pro-tip: If you’re caught between two sizes with AS Colour, they generally offer a modern, retail fit: so if you like it baggy, size up!
6. Did You Forget About the "Colour Shift"?
Your computer screen glows. It uses RGB (Red, Green, Blue) light to show you colours. Printers use CMYK (Cyan, Magenta, Yellow, Black) ink.
That neon green that looks like it's vibrating on your MacBook? It will likely look a little more "forest green" when it hits the fabric. This is just physics.
The Fix: Use Print-Ready Colour Modes. When designing your artwork, set your workspace to CMYK. This gives you a much more realistic expectation of how the final product will look. If colour matching is absolutely critical for your brand, let us know so we can help you navigate the process.

7. Are You Rushing the Finish Line?
You’re in a hurry. You need shirts for an event tomorrow. You upload, click buy, and hope for the best.
Then the shirts arrive, and you realize you spelled "Saturday" wrong. Or your logo is sitting way too low on the stomach instead of the chest.
The Fix: Take Five Minutes. Slow down. Check your spelling. Look at the digital mockup. Ensure your design is at least 2cm away from any seams or zippers (ink can pool in the gaps and look messy).
