## Edit and prove a label layout

1. **Open the prepared template draft**

   Open the prepared template draft.

   A draft is separate from the published template. Changes here do not affect accepted labels or live rules.

2. **Select the SKU text object**

   Select the SKU text object.

   Choose the SKU object using the object list. Numeric properties are in millimetres and the safe print margin is enforced.

3. **Try an out-of-range position**

   Try an out-of-range position.

   The property is refused before it can enter a saved revision. Read the announced error and correct the value.

4. **Set the SKU position to eight millimetres**

   Set the SKU position to eight millimetres.

   Correct the position within the permitted range. Autosave retains a revision, but it does not publish a release.

5. **Apply and review the saved change**

   Apply and review the saved change.

   Moving focus completes the field edit. Check that the saved revision number advances before preparing a proof.

6. **Render the saved layout proof**

   Render the saved layout proof.

   The canonical renderer produces the retained PNG and PDF from the saved revision. Screen appearance alone does not qualify a physical printer.
