From Wikipedia, the free encyclopedia
A highlighter is a form of marker pen which is used to highlight sections of documents in a vivid colour, while leaving the content beneath the marking unobscured. As such, highlighter ink is translucent.

[edit] Styles
Many highlighters come in bright, often fluorescent colours. Being fluorescent, highlighter ink will glow under a black light [1]The most common color for highlighters is yellow, but they are also found in pink, blue, green, orange, and purple varieties.
Highlighters are available in retractable form, [2] or with an eraser on the opposite end of the felt tip.[3] Other types of highlighters include the "trilighter,"[4] a triangularly-shaped pen with a different-coloured tip at each corner, and ones that are stackable. [5]
There are also highlighters with smell, such as popcorn, strawberry, lime, etc.
Dry highlighters (occasionally called "dry line highlighters")[6] are highlighters that, instead of having a felt tip, have applicators that apply a strip of highlighter tape, similar to audio cassette tape. Unlike standard highlighters, they are easily eraseable. [6] They are to be distinguished from "dry mark highlighters"[7], which are sometimes advertised as being useful for highlighting the Bible or other books with extremely thin pages.
[edit] Other Uses
- On rare occasions artists have used highlighters (including erasable highlighters)[8], either alone or in conjunction with other media, to make drawings.
- Word processing software has the ability to simulate highlighting capabilities by using a technique not dissimilar from reverse video on some terminals. Similar to this is the program Web Highlighter, allowing one to "attach highlighting, notes, and links to any Web page viewed with Microsoft Internet Explorer 4.0 or later."[9]
- In professional use, many teachers, bosses, or other high ranking officials have quoted to call the highlighter as "liquid gold." to make their students or employes use less.
- On human skin, yellow highlighter ink glows brightly under a blacklight but is nearly invisible in regular light.
- The redaction of sensitive information by the military and security services is sometimes referred to humorously as 'using the black highlighter'.."[10]
