We highly prefer print-ready PDF files, but other acceptable file types are .jpg, .tiff and .eps files. We can also accept native files from Adobe Photoshop, Adobe Illustrator, or Adobe Indesign. However, sending us native files can potentially hold up or complicate your order if you have missing fonts, fonts not loading properly or missing images. With the modern day ease of creating print-ready PDF files from virtually any native application, and all the positives that come along with printers using them, it's the way to go if possible.
