The horizontal logo is the primary logo and should be used in most instances. Stacked logo is mainly used for large scale collateral’s. Avoid using at small sizes, as it can become illegible. Icon logo is to be used as an addition to the main logo or in tiny spaces.
The logo’s safe zone is equivalent to the height of the “C” on all side for horizontal logo and double that for stacked one.
Custodian logo may be used on solid coloured background or on top of other images, but it always needs to be properly visible.
