A poster is a large format (usually at least A3) plasticized sheet of paper to hang on a wall. Mostly you want to hang posters inside a home (unlike posters, which are posted on the street), only for their aesthetic value. Posters generally feature landscapes, actors, musicians, pin-ups or other famous characters, movie posters, paintings reproductions, etc.
Billboard are large rectangular and horizontal posters (hence the long side represents the base and the short side height). They are usually placed in an outdoor environment, in pre-defined public places. The classic format is 6×2.8m or even called “12 sheets” as it consists of twelve sheets, each of 1×1.4m in size.
The main features of the poster (which are, in principle, the same as the poster) are as follows:
- Great visual impact.
- Have a sort of monopoly (along with the poster) as far as outdoor advertising is concerned.
- Possibility to be strategically positioned (for example, close to a point of sale or anyway in well-defined areas).
- Possibility to be seen by many people and many times.
- Minimal effort from the recipients (which should not, for example, tune into a network or buy a newspaper as it does for other media).
- Extremely synthetic (usually posters are placed in passages, for example along a road, where the times available for reading are minimal – but not necessarily: just think about posters at subway stops).
- Unable to be directed selectively towards a specific recipient (unlike other media it is much harder to predict who will see a poster).
- Possible negative image of the medium that can reverberate on advertising (sometimes environmental billboards have been considered detrimental to the landscape and distracting for driving a vehicle).
Motivational Posters: Poster type commonly designed to be used in schools and offices. The purpose is to show people what they are doing or that they learn from a different perspective. “Motivational posters” also include demotivational posters, which are constructed in the same way as motivational posters, but contain satirical jokes.
There are poster types that can be used for commercial purposes only. An advertising board structure can also be used to host public lighting and even basic radio base stations for telecommunications. Usually, the supporting structure is made up of a steel pole with a coupling flange to the overhanging structure of the advertising signs that may contain telecommunication antennas. The power cables of the luminaires and any antennas are internal to the structure and fixed on special steel wire ropes. This type of structure combines multiple functions, avoiding the construction of telecommunication poles that can disrupt the urban landscape.
