It is important to send the correct types of files for embroidery and screen printing. If the wrong types of files are used the finished product may suffer.
Digitizing images for embroidery, using vector files or high-quality raster images like PNG or JPEG is ideal. Vector files, especially in formats like .AI or .EPS, are preferred as they maintain quality at any size and can be easily converted into embroidery files. When using raster images, aim for high resolution and avoid overly complex designs with many small details, as they can result in excessive stitching.
For screen printing, you’ll generally want to use either vector images or high-resolution bitmap images. Vector images (like those created in Adobe Illustrator or CorelDRAW) are ideal because they are scalable and won’t lose quality when resized. If you’re using bitmap images (like photos), ensure they are high-resolution (at least 300 DPI) and consider converting them to grayscale for easier screen printing.
