Designing your own custom t-shirts and hoodies can be an exciting and fulfilling project. Whether you’re creating personalized apparel for a special event, promoting your business, or just showcasing your creative ideas, custom printing offers endless possibilities. However, many first-time designers make mistakes that can negatively affect the outcome of their designs. These mistakes can lead to poor-quality prints, wasted resources, and unnecessary frustration. Fortunately, most of these common printing errors are easy to avoid with a little attention to detail. In this article, we’ll explore the top 10 printing mistakes to avoid when designing your own t-shirts and hoodies.
1. Choosing the Wrong Fabric for Your Design
The fabric you choose for your custom t-shirt or hoodie plays a crucial role in the final print quality. Different fabrics interact differently with printing methods, and choosing the wrong fabric can result in poor print adhesion, fading, or cracking. For example, cotton fabrics tend to work best for most printing methods, while polyester fabrics can be tricky, especially for techniques like screen printing.
If you’re planning to use DTF ink printing, which works by transferring a design onto a film and then applying it to the garment, you’ll want to make sure you’re using a fabric that allows the ink to be absorbed properly. Cotton fabrics work well with DTF ink printing, and the results can be both durable and vibrant. On the other hand, polyester fabrics may require a different method, like sublimation, to achieve the best results.
2. Ignoring the Resolution of Your Artwork

One of the biggest mistakes in custom printing is submitting low-resolution artwork. Low-resolution images can appear blurry or pixelated when printed, which will make your design look unprofessional and cheap. To avoid this, always ensure your artwork is high resolution—at least 300 DPI (dots per inch) for the best print quality.
Whether you’re using a photo, graphic design, or logo, make sure your images are at the highest resolution possible.
High-resolution files allow for clearer and sharper prints, preserving the details and quality of your design.
This is especially important for complex graphics or text-heavy designs.
3. Incorrect Color Choices and Limitations
Color is one of the most impactful elements of your design, but it can also cause issues if not carefully considered. Colors can appear differently on various fabrics, and some printing methods may have limitations when it comes to color accuracy. For example, certain printing methods, like screen printing, may have trouble capturing subtle gradients or complex color schemes, while DTF ink printing excels at printing intricate designs with full-color images.
When designing your custom t-shirt or hoodie, make sure to test how the colors will look on the fabric you’ve chosen. If you’re using darker fabrics, make sure the design has enough contrast to stand out. It’s also important to consider how the colors will appear after the printing process. Some colors, especially bright or neon shades, may not show up as vividly on dark fabrics.
4. Overcrowding Your Design
It’s tempting to add as many elements as possible to a design, but overcrowding your custom apparel can lead to an overwhelming and cluttered look. Overly complex designs may also be difficult to print, especially if they involve too many small details. Simplicity often works best when designing t-shirts and hoodies.
To avoid this mistake, keep your design balanced. Focus on creating clean, visually impactful graphics with enough space between elements to allow them to stand out. If you’re using text, make sure it’s legible from a distance and doesn’t get lost in the design. A minimalist approach often results in a stronger and more timeless design.
5. Neglecting the Importance of Placement
- The placement of your design on the garment is crucial for creating a visually appealing custom t-shirt or hoodie.
- Designs that are too high, too low, or off-center can make the print look unbalanced or awkward.
- When positioning your design, consider the garment’s fit and structure.
For most t-shirts, centered designs look the most professional, but asymmetrical designs can add a modern touch. For hoodies, think about whether you want the design to be on the front, back, or sleeves. Testing the placement on a mock-up can help ensure that the design aligns well with the cut of the garment.
6. Not Considering the Print Method
Choosing the right printing method for your design is essential for achieving the best results. Different printing methods are better suited for different types of designs and fabrics. For instance, screen printing works well for simple designs with limited colors, while DTF ink printing is ideal for detailed, full-color images.
Consider the complexity of your design and the fabric you’re using when deciding on a print method. If your design features intricate details or a variety of colors, DTF ink printing may be the best choice. If you’re working with a simpler design or a large order, screen printing could be the more cost-effective option. Always discuss your printing method options with your printer to ensure the best results.
7. Forgetting to Test the Design
Before you proceed with a full print run, always request a test print. This allows you to see how your design looks on the actual garment and make any necessary adjustments before committing to a large order. A test print can help you identify issues with color accuracy, design placement, or print quality.
If you’re using a new printer or trying a new printing method, testing is especially important. For example, DTF ink printing can produce different results depending on the fabric, so it’s important to test the design to make sure it turns out as expected.
8. Overlooking Size and Fit of Your Design
The size of your design is just as important as its look and placement. A design that works well on a small shirt may look too small or too large on a larger size. When designing your custom apparel, take into account the varying sizes of shirts and hoodies and adjust your design accordingly.

Ensure that the design is properly scaled for different garment sizes, keeping in mind the print area. For hoodies, be mindful of how the design fits on the front, back, and sleeves, especially since hoodies tend to have a more complex structure than t-shirts.
9. Not Using the Right File Format
Using the wrong file format can cause significant problems in the printing process. Different printing methods require different file types. For example, vector files (such as SVG or AI) are ideal for designs that need to be scaled without losing quality, while raster files (such as PNG or JPEG) work best for full-color images with transparent backgrounds.
Before submitting your design, make sure to ask your printer for the recommended file format. Avoid using file formats like JPEG for detailed designs, as they may not print well and can result in pixelation.
10. Skipping the Fine Print: Read the Terms and Conditions
Finally, don’t forget to read the terms and conditions of the printing company before submitting your order. Many printers have specific guidelines regarding design restrictions, file submissions, pricing, and delivery times. Failing to understand these details can lead to unexpected costs or delays.
Before moving forward with your order, review the fine print to make sure you’re fully aware of any potential restrictions or fees. This will help you avoid misunderstandings and ensure a smoother printing process.
Final Thoughts
Designing custom t-shirts and hoodies is a fun and creative process, but it’s important to avoid common mistakes that can compromise your final product. From selecting the right fabric and resolution to choosing the correct printing method and placement, attention to detail is key to achieving professional-quality prints. By following these tips and avoiding these common pitfalls, you’ll be well on your way to creating custom apparel that stands out for all the right reasons. Whether you’re using traditional methods like screen printing or newer options like DTF ink printing, making informed decisions will ensure that your designs look amazing and last for years to come.
