Our upload feature is intended to be used with complete designs.
You can upload most image file formats, such as JPEG, GIF, TIFF, PNG, EPS, AI, or even PDF.
We recommend your images to have a resolution of 600 ppi (pixels per inch) to ensure the highest quality printing of your document, but we require a minimum resolution of 300 ppi.
This means that for a 3.5″ x 2″ business card (without bleed) your image file needs to be at least 1050 × 600 pixels (at 300 ppi).
To achieve the best color accuracy it is recommended that you have proofed and saved your images in CMYK before uploading.
