Signwriters apply the lettering for various signs on windows, building contractor signboards, walls of buildings, trucks, etc.
Signwriters prepare rough sketches from specifications and plan the lettering. They measure the surface onto which the lettering is to be placed and mark the height and position of the letters in chalk to ensure correct spacing. They then paint the sign, spreading the paint evenly and making good outlines and apply a second coat of paint when the first is dry.
Signwriters are frequently called upon to place signs on shop windows. Different techniques are used to paint on glass. Gold leaf is applied for gold lettering, which is usually backed with paint. Signwriters also paint logos and simple illustrations in some cases.
