Decorate the screen, not the printout
A company logo or a subtle pattern set as the sheet background can give the on-screen document more personality. Just keep in mind this background is a display-only feature and will not appear anywhere on a printed page.
A different tool for images that must print
If you actually need a logo or watermark-style image to appear in printed output, inserting it as a regular picture (or using a header/footer image) is the right approach instead, since the sheet background feature was never designed to reach the printer.
