A bleed area error means that your design does not fully extend into the required bleed area for printing.
To fix this:
Make sure your background colors or images extend all the way to the edge of the bleed area (not just the trim line)
Resize or reposition your design so there are no white edges beyond the trim
If you’re using a design program, ensure your file includes the correct bleed settings (typically 0.125" on all sides)
After making these adjustments, re-export your file and upload it again. This will help ensure your final printed piece trims correctly without unwanted white borders.
