Poster Specifications

From justcreativedesigns.com;

A poster should be:
Aesthetic – It should get attention so the message is delivered.
Focused – It should focus and communicate on a single message.
Ordered – The sequence should be well-ordered and obvious.
You should also remember a poster is going to printed in a relatively large format so anything you do should be done using a high resolution. ie. Use a high resolution setting on your camera or scanner when digitising your concepts. A good starting point is at least 150ppi.
You should also consider other factors of the poster design such as the film title, classification, leading cast, distributors, directors, producers etc. The best way to find out what should be on a poster is by looking at other poster designs.
