Mark Set Conditions
The Conditions section of the Mark Engraver is the same for the four categories of Mark Sets. By default you see one line where you can enter criteria. Criteria lines can be added, edited or deleted. The printing of the marks can also be limited to proofs.
Examples of conditions:
Apply When all criteria are met with criterion $product.name equals MyProduct.
Apply When some criteria are met with criterion $press_sheet.side.press.name equals Large Press.
*Click a Mark Set category and then the Name of a Mark Set to display the Conditions section.
Apply to “Split for Proof” results only
Select this check box if you only want the mark set to appear on the proofs of a press sheet and not on the actual press sheet when it is printed. If you select this option, the proof-only marks do not appear in the Mark Sets inspector nor in Sheet View and no checks are performed for conflicts. Proofs always include the actual press sheet marks.
Apply
Always: the Mark Set is always applied and does not take the criteria into account.
Manually only: The Mark Set can only be placed manually.
When all criteria are met: The Mark Set is only applied when all the criteria lines are true.
When some criteria are met: The Mark Set is applied when at least one of the criteria lines is true.
The selected condition is indicated with an icon in the Mark Sets list.

a string: e.g. your Product, your Press
a number with/without unit: e.g. 1000 mm
