1. Supplying your sign professional with vector artwork and all fonts outlined will make the turn around time on your sign project go faster.
2. When choosing a color for your sign, make sure the color of your logo has enough contrast from the building wall color to be seen.
3. Sign projects can take a while to do correctly. Make sure you think about your signs early so you are not rushing to put something up in hurry at the end. The larger the project the more time you might need.
