In print design, a "bleed zone" refers to the area of a document that extends beyond the edge of the final trimmed size. It's an essential part of the layout that ensures no unprinted edges appear on the finished product.
Here's why it's important:
During the printing and cutting process, small shifts can occur. The bleed zone ensures that if there's any slight misalignment, the printed design will still cover the entire printable area without leaving unwanted white borders.
How It Works:
When you design a document in the Creator Suite, you will see that there is a small grey area around the actual artboard that represents the printable area of the products, indicated by the purple dotted line outside of the artboard.
This is the so-called bleed zone that your design needs to be spread onto. Make sure your artwork extends into this area when designing.
