Expand or collapse content What needs to be considered as Artifacts

The purpose of this technique is to show how purely decorative images in PDF documents can be marked so that they can be ignored by Assistive Technology by using the /Artifact tag. This is typically accomplished by using a tool for authoring PDF.

In PDF, artifacts are generally graphics objects or other markings that are not part of the authored content. Examples of artifacts include page header or footer information, lines or other graphics separating sections of the page, or decorative images.

1. Headers

1.1. Title of the PDF  with multiple pages

This only applies to PDF with multiple pages and if title shows in all pages. The title should only be read by the accessible reader in the first page of the PDF. The title on other pages should be converted to artifact.

1.2. Page numbers

2. Footers

3. Decorative images

4. Lines used as separators

5. Tables used as layout
