Artboards in Sketch can also be directly exported, forgoing the need to add extra slice layers to the document. Simply click “Make Exportable” and define your export settings. With this applied, they’ll appear in the Export dialog.
Exporting Artboards is particularly useful in the case of sharing your designs. Developers and colleagues will be able to see how a final product is intended to look for implementation.
In addition to exporting Artboards individually along with other layers, all Artboards can be exported to one PDF file, ideal for presenting designs. To do this, choose File › Export Artboards to PDF… from the menu. You can define the order in which Artboards will appear by changing the Artboard Export preference.
