The poster is a technique of spreading the information that allows to reach large audiences without investing large resources. Their communication options depend largely on the technical and aesthetic quality and its proper location.
The poster can be made with different techniques but generally must meet certain requirements to run:
Contrast: The main elements and figures perceive more clearly when contrasted strongly with each other: its brightness, colour, texture, form, techniques used, etc.
Formal Simplicity: broad surfaces of uniform colour and simplified forms in detail are more easily visible.
Clear and well structured Composition: Elements and figures should be organized in a composition which provides an overview of all and fundamentally important.
