5. Produce the final graphics: Using design software, produce the final marketing and advertising graphics in a high-quality format suitable for the intended use (print, digital, etc.).
6. Implement the graphics: Use the marketing and advertising graphics in the appropriate marketing and advertising channels, such as print ads, digital advertisements, billboards, and packaging.
