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

Look, I get it. You’ve got a killer idea for a shirt. You can already see your team wearing it, or you’re ready to launch that new streetwear brand. You hit "order" and wait by the door. Then, the box arrives. You open it up, and... it’s not right. The logo is blurry. The colors are off. The fabric feels weird.

I’m Paolo, the CEO of So Boss. I’ve seen thousands of orders come through our shop, and I’ve seen every mistake in the book. Most of the time, these errors are totally avoidable. You don’t need to be a graphic designer or a printing pro to get a great result. You just need to know the pitfalls.

Let’s get your merch right the first time. Design. Print. Profit.

1. Using Low-Resolution Artwork

Is your logo looking a bit "crunchy" on screen? If it looks fuzzy on your phone, it will look ten times worse on a t-shirt. This is the number one issue we see in custom t-shirt printing. People pull a low-res thumbnail off Google or a small logo from their email signature and expect it to look crisp on a chest-sized print.

The Problem: When you enlarge a small image, the printer has to "guess" where the pixels go. This leads to jagged edges and a blurry mess.

The Fix: Always use high-resolution files. We’re talking a minimum of 300 DPI (dots per inch) at the actual size you want it printed. If you can, send us a vector file (like an AI, EPS, or PDF). Vector files use math instead of pixels, meaning they can be scaled to the size of a billboard without losing a single drop of quality.

2. Picking the Wrong Printing Method

Are you ordering five shirts or five hundred? The "how" matters just as much as the "what." A common mistake is choosing a method that doesn't suit the quantity or the design.

The Problem: Trying to use screen printing Australia wide for a single shirt order. Screen printing requires physical screens to be made for every color. It’s expensive and slow for small batches. Conversely, using DTG for a massive 500-piece order might not be the most cost-effective route if you only have a one-color logo.

The Fix: Match the method to the mission.

• DTG (Direct to Garment): Perfect for small runs, no minimums, and full-color photos. (We offer same-day dispatch for this!)

• DTF (Direct to Film): Great for hoodies and vibrant designs that need to last on tougher fabrics.

• Screen Printing: The king of bulk orders. High quality, very durable, but requires higher quantities to make sense.

3. Ignoring Fabric Compatibility

Do you know what your shirt is made of? Not all ink plays nice with all fabrics.

The Problem: You want a vibrant, photographic print on a 100% polyester sports jersey using DTG. Here’s the reality: DTG ink is designed to bond with natural fibers like cotton. If you try to DTG print on pure polyester, the ink might not soak in correctly, leading to a dull print that washes off.

The Fix: Read the label. If you’re going for custom hoodies Australia style (which are often a cotton/poly blend), we usually recommend DTF or Screen Printing. If you’re doing standard tees, stick to 100% cotton for the best DTG results. (We love AS Colour for a reason, the quality is consistent and they print like a dream).

4. Overcomplicating the Design

Is your design too "busy"? Sometimes, less really is more.

The Problem: Adding too many small details, thin lines, or tiny text. On a computer screen, you can zoom in. On a t-shirt, those tiny details might "fill in" with ink or disappear entirely. If you have five different fonts and ten different colors, the shirt starts to look like a messy flyer rather than a piece of apparel.

The Fix: Keep it bold. Keep it simple. Use high-contrast colors (e.g., white ink on a black shirt). If you’re doing screen printing Australia, remember that every extra color adds cost and complexity. Stick to 1-3 colors for bulk runs to keep your budget in check.

Think. Simplify. Print.

5. Poor Design Placement

Where is that logo going? A great design in the wrong place looks amateur.

The Problem: The "Belly Print." This happens when a design meant for the chest is placed too low. It ends up sitting over the stomach, which is rarely flattering. Another common issue is "pocket" logos that are placed too far into the armpit.

The Fix: Follow the standard rules. A center-chest print should usually start about 5-8cm down from the collar. A "left chest" logo should be aligned with the edge of the collar, not the seam of the shoulder. If you aren't sure, ask us for a mockup. We do this every day.

6. Getting the Sizes Wrong

Are you only ordering Large? Unless you’re dressing a very specific group of clones, your sizing needs to be diverse.

The Problem: You order 50 shirts for an event and guess the sizes. You end up with 30 Mediums left over and a line of people asking for 2XL. This is a waste of money and a headache for your brand.

The Fix: Survey your team or audience first. If you can’t, follow a standard "bell curve" distribution: a few Smalls, more Mediums and Larges, a good chunk of XLs, and don’t forget the 2XL and 3XL options. People appreciate being included.

7. Rushing Without a Proof

Are you in a massive hurry? We love speed (we offer same-day DTG in Sydney and Brisbane!), but speed shouldn't mean carelessness.

The Problem: Skipping the "final check." You’re so excited to get the order in that you don't notice the typo in your own phone number or the fact that the logo is slightly crooked in the file you uploaded. Once it’s printed, it’s permanent.

The Fix: Take five minutes. Step away from the screen, grab a coffee, and come back to look at your design with fresh eyes. Check the spelling. Check the dates. Check the colors. (Remember: colors on a glowing screen look different than ink on fabric).

How do I know which method is best for my design?

It depends on your art and quantity. If it’s a photo, go DTG. If it’s 100 shirts with a 1-color logo, go Screen Printing. If it’s a hoodie with a vibrant logo, go DTF.

Can I get my shirts today?

Yes! We offer same-day printing and dispatch for DTG orders. (Orders must be in by the cutoff time, check our local pages for Brisbane, Sydney, and Melbourne for specifics).

Do you have a minimum order?

For DTG and DTF, no! You can order just one. For screen printing, we usually have a minimum to keep it cost-effective for you.

What’s the best brand to print on?

We highly recommend AS Colour. They are the industry standard for quality, fit, and "printability."

Can I print over the seams?

Generally, no. Printing over seams or zippers causes the ink to pool or gap, which looks messy. We recommend keeping your design at least 2cm away from any seams or zippers.

Is custom printing expensive?

It doesn't have to be. By choosing the right method and avoiding these seven mistakes, you can get high-quality gear without breaking the bank. Check our Brisbane Small Business Guide for tips on branding on a budget.
