This design specification document outlines the limits, demands, and wishes for an X-Factor poster. It cannot copy other posters, use too much color or writing, or be A4 or A5 size. The poster must advertise the X-Factor event with the date and time, be easy to understand with bright colors, and be at least A3 size. Ideally, the event would also be advertised online and on TV, the poster would have nice effects and bright colors using various materials, and be a large size to include more details.
