What happens if I submit a low-resolution file to 4OVER4.COM?

4OVER4.COM's upload system checks resolution as your file comes in, so a low-res file rarely slips through unnoticed.

• Files below the recommended resolution get flagged during upload
• You receive a warning and a chance to swap the file before printing
• If you proceed anyway, the print matches exactly what you submitted

A low-resolution file will look soft or pixelated in the final print, most visibly in photos and gradients, so it is worth replacing when the system flags it. Aim for 300 DPI at final size to be safe.
