What is a Vector File?

Which file type of is best for your design?

Vector files (such as AI, EPS, or SVG)

Vector files are the best option for most apparel printing methods, especially screen printing, vinyl cutting, and embroidery. They’re made from smooth lines and shapes, so they can be resized to any size without losing quality. This is ideal for logos, text, and simple graphics that need to look sharp and consistent on different garments. Printers prefer vector files because they’re easy to adjust and produce clean, professional results.

Raster files (such as PNG or JPG)

Raster files are made from tiny dots, like photos taken with a camera. These are best for detailed designs, photographs, or artwork with shading and texture, and they’re commonly used for direct-to-garment (DTG) printing. For apparel, they need to be high resolution so the print doesn’t look blurry. While they’re not as flexible as vector files, they work well when the design is complex or photo-based.

PNG files with transparent backgrounds

PNG files are a popular choice for DTG printing and some heat-transfer methods because they can have transparent backgrounds. This means the design prints cleanly onto the fabric without a visible box around it. They’re best for full-color designs or artwork that isn’t easily converted into simple shapes, as long as the image quality is high enough for printing.

Embroidery digitized files (such as DST or PES)

For embroidered apparel like hats, polos, or jackets, standard image files aren’t enough. The design must be converted into a special embroidery file that tells the machine how to stitch the design. These files are best for simple logos and text, as very fine details don’t translate well into thread. This format ensures the design stitches out cleanly and holds up over time.

Sublimation-ready files (high-resolution raster or vector)

Sublimation printing works best with high-quality files that have strong colors and clean edges. Vector files are ideal, but high-resolution raster files also work well if they’re properly sized. This method is used for polyester garments and allows ink to soak into the fabric, so designs feel smooth and permanent. Clear, well-prepared files ensure vibrant, long-lasting prints.
