my question is specific to adobe artboards. i have 4 artboards of same dimensions of 1080px by 1080px. now i want to take only 1 background image that will split into all artboards. 

generally all artboards have their own backgrounds separately.

this image will explain what i want ?? [![artb](https://i.stack.imgur.com/4R7th.png)](https://i.stack.imgur.com/4R7th.png)
