In the outer circle, it is mandatory to use frames with signature blue elements.
In addition to the rectangles placed at 0-, 15- and –15-degree angles, other geometrical background elements may be added to the content area of the designed surface. Their corners must coincide with the crossing points of the base grid lines.
When placing a rectangle at a 15- or –15-degree angle, at least one corner must lie on the base grid.
Background elements must intersect with the edge of the designed surface.
Background elements may be either in a single colour or filled with a photo or other image material.
