When it comes to T-shirt printing, the file extensions that are typically used are related to image and graphic design files. Here are some common file extensions that are used in T-shirt printing: (when in doubt ask your designer for these types of files)
- .ai - Adobe Illustrator file, which is a vector-based graphic design file format
- .eps - Encapsulated PostScript file, which is another vector-based graphic design file format
- .pdf - Portable Document Format, which can be used to save vector-based or raster-based images.
- .jpg/.jpeg - JPEG image file, which is a raster-based image file format
- .png - Portable Network Graphics image file, which is another raster-based image file format that supports transparent backgrounds.
- .psd - Photoshop Document file, which is a raster-based image file format used by Adobe Photoshop
- .cdr - CorelDRAW file, which is a vector based graphic design file format
It's important to note that some printers may prefer specific file format, it is best to check with the printer what format they accept. Additionally, the file should be in high resolution and the color mode should be in CMYK (Cyan, Magenta, Yellow, and Black) as it is the standard color mode used in printing. Also, if the design has multiple colors, it is best to provide a vector-based file, like .ai or .eps as it will allow the printer to separate the colors and print them separately.
