What to know before overlaying

Two PDFs, one output. The overlay PDF is layered on top of every page of the base PDF.
Use transparent overlays. A logo, watermark or stamp on a transparent background gives the cleanest result.
Match page sizes. Overlay and base PDFs work best when their page dimensions are the same.
