1. Understanding Image Resolution and DTG Print Quality

When preparing your file for DTG printing, it is crucial to consider image resolution, as it directly impacts the final print quality on your custom t-shirt:

High-Resolution Images

To ensure a crisp, detailed print, use high-resolution images with a minimum of 300 dots per inch (dpi). Low-resolution images can result in blurry, pixelated prints that detract from your design’s impact.

Vector vs Raster Files

While DTG printing primarily relies on raster images, using vector files when possible is advantageous, as they can be resized without losing quality. For raster files, always confirm the image dimensions in the print file match the desired print size.

Resampling Images

Avoid enlarging or resampling low-resolution images to compensate for a lack of detail, as this can lead to poor print quality. Instead, obtain the highest resolution version of the image possible before submitting your file for DTG printing.

2. Selecting the Right Image Format for Your Design

Choosing the appropriate image file format is essential for maintaining design integrity and optimising your DTG print file:

PNG Files with Transparency

For images with transparency or intricate details, utilise the PNG file format. This format maintains a transparent background, eliminating the need for a background colour on your custom t-shirt.

JPEG Files for Photography and Detailed Images

The JPEG file format works well for photographic images or those with high levels of detail, offering a high-resolution image that maintains colour accuracy and depth.

Converting from Other Formats

When working with images in other formats, such as TIFF or Photoshop (PSD) files, convert them to an appropriate format for DTG printing to ensure compatibility with the printer and maintain design quality.

3. Preparing Your Design for DTG Printing: Colour Management Tips

Managing colours effectively is critical for attaining accurate prints that reflect your original design:

Colour Profiles

Ensure your print file uses a CMYK colour profile, as DTG printers typically require this format. While some printers can convert RGB to CMYK, manually converting the colours ensures you maintain control over the final output.

Visualising on Fabric

Keep in mind that colours may appear differently when printed on fabric compared to the digital version on-screen. Use the colour picker tool available in most design software, or work with Direct Style Printing’s team to identify the best colour match for your design.

Adjusting for Dark Garments

When printing on dark or coloured garments, modifications to the print file may be necessary. A white ink underbase is often used to ensure the design colours remain bright and vibrant. Consult with Direct Style Printing to guarantee a flawless result on darker fabrics.

4. Ensuring a Seamless Transition from Digital to Print

Effectively translating your design from a digital file to a DTG print requires attention to detail and careful planning:

Test Prints and Iterations

Consider producing test prints to assess the accuracy of colours, design placement, and overall print quality. Based on the test print result, make any necessary adjustments to your file before proceeding with the final print.

Collaborate with Your DTG Printer

Leverage the expertise of Direct Style Printing’s team to ensure optimal results for your custom t-shirts. Maintain open communication, ask for feedback, and share your design objectives to align expectations and guarantee a seamless DTG printing experience.

5. Choosing the Right Fabric and Garment Style

Choosing the right fabric and garment style is crucial in creating custom t-shirts that look and feel great. When choosing the fabric, consider factors such as softness, durability, and breathability. Direct Style Printing uses high-quality cotton, polyester, and blends to ensure the best possible print results.

The garment style is also essential, as it can impact the final print quality and the overall aesthetic of the custom t-shirt. Factors to consider when selecting the garment style include the placement of the design, the size of the print, and the intended use of the custom t-shirt. For example, a fitted t-shirt may be more suitable for a fashion-oriented design, while a relaxed fit may be better for a more casual design.


Optimising your DTG print files is an essential aspect of producing impeccable custom t-shirts that capture the essence of your online clothing shop, social media brand, or clothing brand. By understanding image resolution, selecting the appropriate file format, managing colours effectively, and working closely with your DTG printer, you can ensure a smooth transition from digital to print and create remarkable garments that elevate your brand.
