The dummy will typically include placeholder text and images, as well as the placement of advertisements. It is used by the editorial and design team to make sure that the publication is balanced and visually appealing.
Dummies are also used by the printing team to make sure that the publication can be printed correctly. They will check the size and orientation of the pages, as well as the placement of the folds.
Once the dummy is approved, it will be sent to the printer for production.
