The Gorenjski glas newspaper is the main local newspaper of the Gorenjska region in Slovenia. The municipal supplement project was based on the intention of combining the newspapers of the various municipalities of Gorenjska using the same spreads. Each municipality would thus have its own newspaper appearing in Gorenjski glas as a supplement.
The flexible system allows the insertion of the coat-of-arms and name of the local municipality newsletter into the spread, which is in turn linked to the corporate identity of the Gorenjski glas newspaper.
