Most preferred format is PDF Illustrator or Coreldraw vector artwork and all fonts converted to outlines/curves. We also except .jpg, .pdf, .tiff, .png, .psd or .bmp files (please enlarge artwork 4 times larger than the pin size). We highly recommend the use of Pantone Matching System colors in your art in order to reproduce the colors you require. For our Digital Pins, artwork should be at least 300 dpi or higher.
