To design the school logo is an art. To use it in the right way is again very important. The colours used should not change at every place it is been used. The dimentions should have a similarity and right placement.
A manual should be made for the usage of the LOGO. It should be explained as in how to use the logo on Letter Head, Visiting Cards, Bus, Glow Sign, Advertisements etc.
A sample file is attached to ensure a manual exists..
