Loghi

Loghi, the plural of logo in Italian, refer to graphical symbols or marks used to identify a company, organization, product, or service. A logo may be a logomark (a symbol), a logotype (a wordmark), or a combination of both, and it functions as a central element of a brand's visual identity. Logos appear on products, packaging, advertising, digital interfaces, and corporate communications, serving to promote recognition and trust.

Design types include logomarks, logotypes, and combination marks. A successful logo is typically simple, distinctive, versatile, and timeless, and it must work across sizes, media, and color variations. Color, typography, and form should reflect the brand's personality and values while ensuring legibility and accessibility for diverse audiences.

In practice, logos are usually created as vector graphics to preserve quality when scaled. Common file formats include SVG, AI, and EPS for print or scalable uses, and PNG or JPEG for web. Brand guidelines specify how a logo may be used, including clear space, minimum sizes, color versions (full color, single color, or grayscale), and prohibited alterations.

Legally, logos are often protected by trademark law and require controlled usage to maintain brand integrity. Organizations typically publish guidelines to ensure consistent reproduction by partners and vendors and to avoid brand dilution or confusion.

Historically, logos evolved from simple marks used by merchants to identify goods, progressing through corporate insignia in the 20th century to contemporary, dynamic branding systems that adapt across platforms. As branding and digital media expand, loghi continue to be central to identity, communication, and consumer recognition.
