The quality of a t-shirt design is influenced by the file format selected. This is because aspects like resolution, scalability, transparency, and colour accuracy directly impact the final print results. For providing designs for custom shirt printing, vector files and raster files are the two main choices.
Vector files such as AI, EPS, SVG, and PDF are considered the gold standard. They offer unmatched scalability and precision, making them perfect for logos and complex designs.
When it comes to raster files, PNGs are a great choice. They stand out for their sharpness, vibrant colours, and ability to support transparent backgrounds. PSD files are also helpful, providing flexibility with layered and editable designs. PDFs are versatile, preserving both vector and raster elements, making them ideal for finalised artwork.
However, there are file formats that should be avoided. Formats like JPG, GIF, and TIFF are unsuitable due to their limited resolution, lack of transparency, and overall quality issues.
To ensure the best print results, consider additional tips such as using files with a minimum resolution of 300 DPI and converting them to CMYK colour mode for print accuracy.
Lastly, consulting your printer’s preferences can help you achieve professional-grade t-shirt prints.

Why File Types Matter for T-Shirt Printing?
Not all file types are equal when it comes to personalised t-shirt printing. Some formats preserve the intricate details of a design, while others may lead to significant quality loss. Choosing the correct file type can make all the difference in the final result.
Here’s why it’s crucial:
- Resolution Preservation: Low-quality files often appear pixelated or blurry when printed, affecting the design’s overall appearance. A high-resolution file ensures sharp, clean prints.
- Scalability: Certain file types, like vector files, can be resized without losing quality. This makes them ideal for designs that may need to be printed in different sizes.
- Colour Accuracy: Using the proper colour mode, such as CMYK, ensures the colours in your design print as vividly and accurately as they appear on the screen.
- Transparency: Formats like PNG are essential if your design has transparent elements or requires a transparent background. On the other hand, others, like JPG, do not support transparency.
Best File Types for T-Shirt Printing
Different file formats offer unique advantages depending on the design complexity, the need for scalability, and the requirement for transparency. Below are some of the top file types used in t-shirt printing, each with its own strengths to help achieve professional-grade results.
Vector Files
File Types: AI, EPS, SVG
Vector files are the top choice for t-shirt printing due to their scalability and precision. Unlike raster files, which use pixels to define an image, vector files are based on mathematical paths. This allows them to be resized without losing quality, making them perfect for designs that need printing in various sizes.
Vector files are ideal for logos, detailed illustrations, and text-heavy designs, as they maintain sharpness and clarity no matter how large or small the design is printed.
Why Use Vector Files?
- Perfect for intricate designs and logos.
- Retain sharpness at any size.
- Compatible with most professional printers.
Best Use Case:
- Logos, text-heavy designs, and detailed illustrations.
Pro Tip
Save your vector file as a PDF to increase compatibility with different devices and printing software.
PNG Files: High-Quality Transparency
File Type: PNG
PNG files are commonly used for designs that require transparent backgrounds. These files maintain sharp edges and vibrant colours, making them an excellent choice for simple graphics or photographs that require high-quality resolution and clean edges. PNG is also popular for designs that must be printed on various coloured fabrics, as the transparent background ensures the design looks sharp without any unwanted borders.
Why Use PNG?
- Supports transparency, which is essential for designs without backgrounds.
- Retains high-quality colours and details.
Best Use Case:
- Simple graphics, minimalistic designs, or photos with clean outlines.
Resolution Tip
Permanently save your PNG files at a resolution of at least 300 DPI (dots per inch) to ensure the design prints crisply and clearly.
PSD Files: Editable and Detailed
File Type: PSD (Photoshop Document)
PSD files are ideal for designs that require multiple layers or editing after the design is completed. As a native Adobe Photoshop format, PSD allows you to adjust individual design elements such as colours, fonts, or effects even after the design has been finalised. This is especially useful for complex designs that may need revisions before printing.
Why Use PSD?
- Fully editable with multiple layers.
- Ideal for experimenting with design elements and making adjustments.
Best Use Case:
- Complex designs that need fine-tuning before finalising for print.
Pro Tip
Flatten your PSD layers and convert the file to a vector or PNG format for final printing to ensure printer compatibility.
PDF Files: Versatile and Reliable
File Type: PDF
PDF files are an excellent choice for finalised t-shirt designs. They combine the best features of both vector and raster formats, preserving the design integrity across multiple devices and software. PDFs are also highly versatile, making them compatible with most professional printing equipment, ensuring that your designs print consistently and accurately.
Why Use PDF?
- Ensures high-quality printing, preserving design details.
- Compatible with most printing equipment.
Best Use Case:
- Finalised designs that are ready for production.
Pro Tip
Ensure your PDF includes vector elements to preserve scalability when printing.
File Types to Avoid for T-Shirt Printing
While some file formats may seem convenient, they often fail to meet the requirements for high-quality t-shirt printing. Using the wrong file type can lead to poor resolution, distorted colours, or unnecessary file size issues. Here are some standard formats to avoid:
JPG (JPEG)
JPG files are commonly used for web images due to their small file sizes, but they fall short for t-shirt printing. These files compress the image, which reduces resolution and overall image quality. As a result, they often appear pixelated or blurry when printed and significantly when enlarged.
Why Avoid JPG?
- Poor resolution for printing, especially at larger sizes.
- Compression causes loss of image detail.
- No support for transparency.
GIF
GIF files are best suited for simple animations and web use but are not ideal for printing t-shirts. The format has a limited colour palette (only 256 colours), which can significantly reduce the vibrancy and detail of your design. Additionally, GIF files have low resolution, making them unsuitable for professional printing.
Why Avoid GIFs?
- Limited colour range results in dull or inaccurate prints.
- The low resolution affects print sharpness.
- No support for transparent backgrounds.
TIFF
TIFF files are known for their high-quality images and lossless compression, but they are large in file size and not particularly beneficial for t-shirt printing. While TIFFs may offer excellent detail, the file size could be more manageable. Also, the format offers no significant advantages over other formats like PNG or vector files.
Why Avoid TIFF?
- Large file sizes can slow down processing.
- Doesn’t offer much improvement over other formats.
- It may not be compatible with all printing equipment.

Pro Tips for Optimising Your Design Files
Optimising your design files is essential to achieve the best possible results for your t-shirt prints using any decoration method. Here are some key practices to follow:
- Use High Resolution
Ensure your design is at least 300 DPI (dots per inch). Low-resolution files can appear pixelated or blurry when printed, negatively impacting the overall quality. Higher resolution ensures sharp and clear prints, even when scaled up.
- Convert to CMYK
Switching your file’s colour mode from RGB (used for screens) to CMYK is essential when creating a print design. CMYK is the standard colour mode for printing and ensures that your colours will be as vibrant and accurate as possible on your t-shirt.
- Ask Your Printer
Different printing services may have specific file requirements. To avoid surprises, checking with your printer to ensure your file meets their preferences is always a good idea. Some may prefer specific formats or have restrictions on file size.
- Keep a Master File
Always retain an editable version of your design. Whether it’s a PSD, AI, or another editable format, having a master file allows you to make changes in the future, such as adjusting colours, text, or design elements. This is especially important if you need to resize or adapt your design later.
Common Questions About T-Shirt Printing File Types
What’s the difference between CMYK and RGB?
CMYK is used for printing and ensures accurate colours, while RGB is used for digital screens. CMYK uses four colours (Cyan, Magenta, Yellow, and Black) to create a wide range of colours, making it ideal for print. Always convert your file to CMYK for printing to avoid colour discrepancies.
Which file type is best for screen printing?
Vector files (AI, EPS, or PDF) are the best choice for screen printing. These file types retain sharp details and scalability, ensuring that your design remains crisp and clear at any size. They are perfect for intricate logos or text-heavy designs.
Should I use a PNG or PSD file for t-shirt printing?
PNG files are great if your design requires transparency or has simple graphics. They retain high-quality colours and edges, making them suitable for designs without backgrounds. PSD files are ideal for layered designs and complex artwork, allowing for easy edits before final printing.
What is DPI, and why does it matter for t-shirt printing?
DPI stands for “dots per inch” and measures image resolution. For t-shirt printing, it’s essential to use a file with at least 300 DPI to ensure the design is sharp and clear. Lower DPI files can appear pixelated when printed.
What file format should I use for multi-colour designs?
For multi-colour designs, vector files like AI, EPS, or PDF are recommended because they allow for easy colour separation, which is essential for processes like screen printing. These formats ensure that each colour is applied correctly and with high precision.
Selecting the best file type for t-shirt printing is the key to achieving sharp, vibrant, and professional results. By following these guidelines and optimising your files, you can ensure your t-shirt designs look flawless every time.
