### Printing a mark that indicates a verification status

If you print a signed document from Desk, the mark indicating the not-yet-verified status appears on the printout. If you print a signed document from Viewer, a mark indicating the verification status at the time of printing appears on the printout. However, no mark will be printed when the signature verification status is hidden from the view.

### Operations in Viewer Control / Viewer Light or Viewer Light Control

You can verify the signature or signature status using Viewer Control, or using Viewer Light Control launched from your web browser.
In Viewer Light or Viewer Light Control no signature can be used. When a signed document is opened, a mark indicating a verification status will be hidden.

### Edit operations and verification statuses

If you add or delete the annotation in Viewer and then perform [Save] or [Write Signature and Save As] operation, that file is regarded as being edited even if the contents have not been changed. For this reason, if you execute [Verify the Signatures] on the signature which was done just before those operations, the result will be [Modified].
