Today they will show you how Highlighters are made!
The first fiber tip pen was invented by Yukio Horie in 1962 in Japan. A highlighter is a fiber tip pen filled with transparent brightly coloured ink. The Avery Dennison Corporation trademarked the name Hi-Liter, they invented the name highlighter, but they did not invent the pen.
A highlighter is a form of fiber tip 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.
