This article explains the "Effective ink coverage is above 320% inside BleedBox" error and provides a solution.
Understanding Ink Coverage
The error message "Effective ink coverage is above 320% inside BleedBox" means that certain areas of your design are very dark. This happens when the combined ink coverage of cyan, magenta, yellow, and black (CMYK) exceeds 320%.
Is this a problem?
Not necessarily! While high ink coverage can sometimes cause printing issues, it's not always a problem. If you're happy with how the darker parts of your design look, you can safely ignore this warning and proceed with your order.
