When you create shares for a company, you have the ability to denote whether a share is to be signed normally or under a seal. This includes printing user specified text on to the generated share certificate as a result of the issue.
The user has the option to change this to a normal signature (via unchecking the tick box) at the time of each share issue.
The text printed by this option can be set within enSecretary maintenance, for details on this please see Share Issue Option.
