Main Difference
The main difference between Logo and Insignia is that the Logo is a graphic mark or emblem commonly used by commercial enterprises and Insignia is a sign of state, corporative or religious dignity, power and honor.
Logo
A logo (abbreviation of logotype, from Greek: λόγος, translit. logos, lit. ‘word’ and Greek: τύπος, translit. 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.
In the days of hot metal typesetting, a logotype was one word cast as a single piece of type (e.g. “The” in ATF Garamond), as opposed to a ligature, which is two or more letters joined, but not forming a word. By extension, the term was also used for a uniquely set and arranged typeface or colophon. At the level of mass communication and in common usage, a company’s logo is today often synonymous with its trademark or brand.
Insignia
An insignia (from Latin insignia, plural of insigne, meaning ’emblem, symbol, ensign’) is a sign or mark distinguishing a group, grade, rank, or function. It can be a symbol of personal power or that of an official group or governing body.
On its own, an insignia is a sign of a specific or general authority and is usually made of metal or fabric. Together, insignias form a decoration with the different elements of a rank, grade, or dignity.
There are many types of insignia, including civil and military decorations, crowns, emblems, and coats of arms.
