In graphic design, mockups are an important element in creating a company's branding and allow for the demonstration of the design code on various branded items — from pen and letterhead to employee uniform.
In web design, mockups are used for presenting design concepts. A mockup of a smartphone or monitor can showcase a webpage or app.
In packaging design, mockups allow designers to try various design concepts, helping to understand how the packaging will look on a store shelf without the need to create a physical prototype.
In marketing and advertising, mockups are used for A/B testing different design concepts in advertising, as well as for creating marketing materials and visual content for websites, online stores, and social media.
The main advantage of a mockup over product photography is that a mockup does not require a finished product. Using mockups helps designers save time, and businesses reduce costs associated with creating physical prototypes.
Due to mockups, designers can easily and quickly make changes in design concept, clients can be confident that the final product will meet their expectations, and users will be pleased with the visually appealing images on social media.
