As long as people have been driving on roads, advertisers have been utilizing the medium of outdoor. Within today's fast-paced environment, people have mere seconds to take in your design!
Remember who you are designing for: don't forget your target audience!
Focus on one SIMPLE idea
Make it memorable: humorous ads tend to receive
the most favorable response from viewers.
The rule of thumb for copy: 7 WORDS or LESS!
Three "elements" work best: one large image, a tag line and a logo.
A good rule to follow: print your design on letter-size paper, tape it to a wall and step back about 4 feet - if you can't read it clearly, you won't be able to read it once it's printed & posted!
Create visual impact with contrasting colors.
Designing for digital billboards is drastically different than traditional static displays: think of digital as an internet or tv ad - rich colors, layered backgrounds, glows, shadows and gradients will create stunning visuals!
With digital billboards, it's imperative that you stay away from white backgrounds: in LED technology, white is a combination of all colors rather than the absence of color (as in print); white appears muddy and less brilliant on these displays.
