You can delete any process layers that you have created or that were originally in the 1up. do not forget: You cannot delete the 1up's structural layer.
To delete a process layer
NOTE: If the tab is unavailable, right-click any of the available tabs, and then check Layers & Objects on the context menu.
If the process layer you are deleting is of the types Lamination or Backing, the layer is removed. (This completes the procedure.)
If the process layer you are deleting is of the types Partial Ink Foiling, Varnishing or Imprint and there are other layers of any of these type available, a message appears:
This means that before the process layer can be removed, the objects assigned to it must be assigned to another layer: in the dropdown list choose a process layer, and then click OK.
If the layer you are deleting is the only one of the types Partial Ink Foiling, Varnishing or Imprint, a message appears:
This means that the objects assigned to the process layer cannot be assigned to any other process layer of the type. Before deleting the selected process layer, you can choose to do one of the following:
Create another layer of the same type, and then assign the objects to it.
Assign the objects to the structural layer, and then delete the process layer.
Change the type of the layer. This spares you the effort of assigning the objects to a new layer.
