microprinted

Microprinted refers to text or patterns produced at an extremely small size, typically only legible with magnification. It is used as a security feature and design element in various printed materials to deter counterfeiting and to convey branding details that are difficult to reproduce with ordinary copying. The term contrasts with standard text, which is designed for readability at a glance.

Common forms include microtext, tiny lettering that runs along lines or curves; microdots, tiny arranged dots that form a picture or message when enlarged; and microline patterns that create the impression of solid color or texture while concealing readable text. Microprinting is typically produced with high-resolution printing processes such as intaglio, lithography, or advanced offset printing, and by selecting fonts engineered for ultra-small sizes. Because the text is often unreadable to the naked eye, verification usually requires magnification or digital zoom.

Applications include currency banknotes, passports and other government-issued documents, security seals, stamps, packaging for high-value goods, and premium credit or identification cards. In currency, microprinting is used alongside other features like holograms and security threads. In branding, microprinting can add a tactile or intricate detail that authenticates the item while being difficult to duplicate exactly.

Limitations include potential degradation of legibility over time or with wear, and the possibility that sophisticated printers and scanners can reproduce or reveal microtext. Verification remains necessary; readers range from simple handheld magnifiers to automated verification systems in banks and at border control.
