You can send us your artwork in the formats of Adobe Photoshop (PSD, JPEG, TIFF, BMP) and Adobe Acrobat (PDF). JPEG is the most undefined format, so we highly recommend sending your artwork in PSD. We also have an online customisation tool that you can use. It is very simple to choose from our pre-designed bags to start adding your customisations. If nothing works, you can send us camera-ready copies of clean laser-printed artworks.
