If a dieline is missing and the outer border of the shape that needs bleed has gaps creating bleed does not easily work.

When the original looks like this:

Normal bleed creation would generate something like

Nice, but not was is needed.

This Process Plan creates a shape of all objects on a page and adds a line to each single object. The width of the line can be adjusted.

In this example the size of the gaps is roughly 13 mm.

The Process Plan creates lines with a thickness of 4 x size of the gaps as a "HelpShape" on a layer and then creates a dieline 4 x size of the gaps inside of HelpShape. It then switches the HelpShape layer off and creates bleed at the dieline.
