Create a PDF containing a circle with its stroke defined as a spot colour, named to match the target tool (for example, Drill). A sample Drill.pdf is attached to this article as a reference.
Open the PDF in PrintFactory Editor and save it as an .aur file in the Grommets folder:
Windows
C:\Users\Public\PrintFactory\Grommets
macOS
HD/Users/Shared/PrintFactory/Grommets
Once saved, the file will appear as an available grommet type for selection in the Workflow step.
In the Grommets workflow step, set Grommet Type to Drill. Configure spacing and offsets as required.
Add a Cutcontour step immediately after the Grommets step. Under Tool Mapping, add a row:
DrillDrillThe spot colour name must exactly match the spot color in the custom Grommet file
