Graphics and text designs (basically any non-photographic content) are best submitted as either vector-based PDFs or Adobe Illustrator (.ai) files. This ensures lines and text are crisp. Please make sure there are no cut or crop lines, all transparencies have been flattened, and all fonts are embedded (or outlined) before saving your designs.
To do this in Adobe Illustrator: select all the text and choose Type > Create Outlines. For best results, we recommend using the following preset to preflight your designs: Adobe PDF/X-1a.
