Stamps, series numbers and shared folders come with VEFdocsKit Pro; VEFdocsKit Free is free and complete for the rest.
A stamp model
A stamp is a model with up to four lines of text, a frame (rectangle, rounded rectangle, ellipse, double frame, or a round stamp whose texts follow the curve), colors, a tilt and an optional ink effect.
Renderings
A model can have several renderings (a small one, a large one). A rendering already used on a document is frozen: to change it, create a new one, so that the stamps already placed stay as they were.
Variables
The numbers are written with variables such as {number}, {folder}, {date}, {page}, {pages} and {user}.
