What resolution should my files be?

Print resolution is measured at the final printed size. The standard is 300 dpi (dots per inch), and it applies to every image in the file.

• Files need a resolution of 300 dpi at the final size; 600 dpi is even better for fine text, thin lines, and detailed logos.
• For edge-to-edge images, use 300 dpi at the bleed size.
• If you do not have access to professional or Adobe programs, you can still hit 300 dpi at print size with simpler tools.
• Do not enlarge small images to fit, since that lowers their effective resolution: a 300 dpi image scaled up 200 percent is effectively 150 dpi and prints soft. Web images are usually 72 dpi and are not suitable, and 150 to 200 dpi prints noticeably softer.
• Check every placed image, not just the document setting. A page set to 300 dpi can still contain a low-resolution photo, and the lowest-resolution element sets the quality.
• Use vector art for logos and type where you can, since it stays crisp at any size, and export a flattened print-ready PDF so the resolution travels with the file. Very large-format pieces viewed from a distance can sometimes use 150 dpi, but 300 is the safe default.

Hit 300 dpi at the size the image actually prints and it will stay sharp. Files below spec are flagged during technical review and you will be asked to submit a higher-resolution version (log in, open the order, and use the Upload button). The online proof preview is intentionally compressed to load quickly, so judge sharpness from your source file at 100 percent zoom.
