Car magnet design must be vivid and direct. It must attract attention and arouse interest in potential customers. Car magnets should also be custom designed for easy recall by the viewer. A magnet that has to much information crammed into the design will be difficult to remember. Color, design and copy brevity are the hallmarks of a good, promotional car magnet. Having said that, some car magnets are extremely effective in simple black and white! Perhaps, you are a graphic designer or have contracted a preferred graphic artist to design your magnetic signage. That's absolutely fine, just make sure your car magnet artwork specifications are in a file format we require when you do order.
