When it comes to custom apparel printing at Savage Merch, ensuring we receive the right type and quality of design files is crucial. High-quality files allow us to create prints that are sharp, vibrant, and detailed, while low-quality or incorrect file types can lead to blurry, pixelated results. Here, we’ll break down the types of file formats best suited for screen printing and DTF (Direct-to-Film) printing and explain the limitations of low-resolution images.
1. Preferred File Formats for Screen Printing and DTF Printing
The best file formats for apparel printing are vector files and high-resolution raster files. Here’s a quick guide to the main types we recommend:
Vector Files: AI, EPS, and PDF
AI (Adobe Illustrator): This is the gold standard for screen printing and DTF printing. Adobe Illustrator files maintain their quality at any size, meaning they can be resized infinitely without losing sharpness or detail. This format is ideal for logos, text-based designs, and any graphic that needs crisp edges.
EPS (Encapsulated PostScript): EPS files are also vector files and are widely supported by graphic design programs. They maintain sharpness and quality, making them an excellent choice for screen printing.
PDF (Portable Document Format): If a PDF contains vector graphics, it’s a solid choice for printing. However, if you’re submitting a PDF, ensure the artwork within it is in vector format, not embedded as a low-resolution raster image.
High-Resolution Raster Files: PNG, PSD, and TIFF
While vector files are preferred, high-resolution raster files can also work if they’re properly prepared.
PNG (Portable Network Graphics): We recommend PNG files for designs with transparency, especially for DTF printing. Ideally, the image resolution should be at least 300 DPI (dots per inch), and the file should be large enough to print at your desired size without losing quality.
PSD (Photoshop Document): If you’re designing in Adobe Photoshop, PSD files work well for complex images, like detailed illustrations or photographic designs. Just make sure the resolution is set to 300 DPI or higher.
TIFF (Tagged Image File Format): This is a high-quality raster format that supports layers, making it suitable for more complex designs. Like PSD files, TIFFs need to be at least 300 DPI to avoid pixelation.
2. File Resolution and Quality Requirements
Whether you’re supplying vector or raster files, maintaining high resolution is essential for a sharp and professional print. Here’s what we recommend:
Resolution: 300 DPI is the minimum for raster files, especially when the design will be printed at larger sizes.
Size: Your file should be large enough to scale to your desired print size without losing clarity. For example, if you're looking to print a large logo on a shirt, a 1000px x 1000px image may be too small and could appear blurry.
3. The Problem with Low-Resolution Files (e.g., Screenshots or Small Images)
While it may be convenient to take a screenshot of a logo or use a low-quality image from the internet, these files often don’t meet the standards needed for high-quality screen printing and DTF printing.
Blurriness and Pixelation: Low-resolution files often look pixelated or blurry when enlarged, which becomes especially noticeable on larger prints, like t-shirts or hoodies.
Loss of Detail: When a low-resolution image is scaled up, details in the design can become fuzzy or completely lost, leading to a poor-quality final product.
Inaccurate Colors: Low-resolution images can sometimes contain inaccurate colors, making it difficult to achieve the exact look you’re envisioning.
For the best possible results, avoid using files from sources like screenshots or images downloaded from social media. These are often compressed and lack the detail and resolution needed for printing.
4. How to Provide Your Files to Us
If you’re unsure if your file is suitable for printing, here are a few ways to ensure we get the best quality possible:
Ask for Help from Your Designer: If you have a designer, ask them to provide your logo or artwork as a vector file (AI or EPS), or at a high resolution (300 DPI) in one of the raster formats mentioned above.
Save or Export at High Resolution: If you’re creating a design yourself, always save or export the file at the highest resolution available to avoid quality issues.
Send Original Files: When possible, send the original design files rather than a copy or a screenshot. This ensures we have the best version to work with.
Final Thoughts
Choosing the right file format and resolution can make a huge difference in the quality of your printed design. By providing high-quality files, you’re helping us deliver prints that are as vibrant and detailed as your original design.
