Remember that Adobe's products (namely Acrobat and InDesign) use 3 terms interchangeably throughout their programs:
Background
Decorative
Artifact

Regardless of the term, they do the same thing: label the item as hidden to screen readers.

In other words, for most part you can think of making something an artifact is similar to doing <img alt=""> in HTML. If you are using Acrobat, you can select the image, and choose the "background" button via the touchup reading order tool.

Assistive technology or content conversion tools would then by default not bother to present such artifact content to a user or export it to some other representation. At the same time there are mechanisms in PDF that make it possible to classify artifacts - e.g. whether an artifact is a page background, or a page number, or a running header, etc. - in case a user wanted to access these anyway.
