When creating a partial varnish it is often desirable to derive the area where varnish shall be applied from actually printed content. At the same time, mostly in order to compensate for less than perfect registration of plates or print heads, it is usually necessary that the varnish extends slightly, maybe by a millimeter or two, beyond the printed content area, to ensure that printed content is always varnished. The fact, that some small area where nothing is printed also receives varnish, is typically not considered a problem.

Along the same lines, but usually in the other direction, a white background may have to be created for printing on transparent substrate – but as the background shall not become visible as such, it needs to be shrunk by a little bit to pull back from the border of the print content area.

Both requirements can now be met very easily by the extended "Shape" feature, using the  "adjust size" setting. This setting was already available for shapes based on page geometry boxes or a custom box but now can also be used for shapes derived from tracing page content or from existing vector paths.

In addition, a new setting "Reduce shape to outer borders" makes it possible to include 'holes' inside print content areas, which can be very handy for the generation of a white background (see example below). Extending/shrinking shapes and 'reduce to outer border' can be freely combined with each other and any of the other options.
