A flyer mockup is a digital or physical prototype that replicates the appearance of a promotional flyer. It serves as a visual representation of how the final printed or digital flyer will look. Designers use mockups to evaluate and showcase their flyer designs in a realistic setting, considering factors such as layout, typography, and color schemes. This enables them to make informed decisions and present clients or stakeholders with a preview of the finished product before it goes into production. Flyer mockups play a crucial role in refining and optimizing promotional materials for maximum impact.
