Logo vs. Watermark — What's the Difference?

A logo (abbreviation of logotype, from Greek: λόγος, romanized: logos, lit. 'word' and Greek: τύπος, romanized: typos, lit. 'imprint') is a graphic mark, emblem, or symbol used to aid and promote public identification and recognition. It may be of an abstract or figurative design or include the text of the name it represents as in a wordmark.

A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper. Watermarks have been used on postage stamps, currency, and other government documents to discourage counterfeiting.
