You can manually edit bleeds to mask portions of the artwork. You can also adjust rectangular bleed margins to crop out extra image area, such as printer's marks, by using negative settings in the bleed margins.
You can edit bleeds by adding points to the bleed path and dragging the points to the desired locations, and by deleting points. Using the Geometry palette, you can adjust the positions of points and sections with greater precision.

Hold down the Option key (Macintosh) or Alt key (Windows) to add or delete points on the bleed path. The Bleed tool pointer changes appearance to indicate its current status:
 Image Modified
indicates that the pointer is in position to add a point to a bleed path
Image Modified
indicates that the pointer is in position to delete a point from a bleed path
Image Modified
indicates that the pointer is too far from all points and paths to be able to perform any actions

You can select bleed points one at a time, or you can select multiple points at the same time by marqueeing them.

To add a point to the bleed path:

1. Select the Bleed tool on the main toolbar.
2. Hold down the Option key (Macintosh) or Alt key (Windows), and click the bleed path where you want to add a point.
3. Drag the point to the desired location, or type coordinates in the X and Y boxes on the Geometry palette.

To delete a point from the bleed path:

1. Select the Bleed tool on the main toolbar.
2. Hold down the Option key (Macintosh) or Alt key (Windows), and click the point on the bleed path that you want to delete.

To move a path segment:

1. Click the path to select it.
2. Drag the selected segment to a new location or type coordinates in the X and Y boxes on the Geometry palette.
   Note: To constrain the movement of the section to only 45-degree or 90-degree angles, hold down the Shift key as you drag the section.

To copy a bleed path from one artwork to another:

1. Select the Bleed tool on the main toolbar.
2. Click the artwork placement in the layout that has the bleed path you want to copy.
3. Select Edit > Copy.
4. Select the target artwork in the layout, or if you want to apply the bleed path to all instances of the artwork, select the target artwork in job properties.
5. Select Edit > Paste.

按住 Option 键 (Macintosh) 或 Alt 键 (Windows) 可在出血路径中添加或删除点。 出血工具指针通过更改外观来表示其当前状态：
Image Removed
表示该指针处在向出血路径添加点的位置
Image Removed
表示该指针处在从出血路径删除点的位置
Image Removed
表示该指针离所有的点和路径过远，不能执行任何操作
