Roller ball pens or roll pens [1] are pens which use ball point writing mechanisms with water-based liquid or gelled ink, as opposed to the oil-based viscous inks found in ballpoint pens. These less viscous inks, which tend to saturate more deeply and more widely into paper than other types of ink, give roller ball pens their distinctive writing qualities. The writing point is a tiny ball, usually 0.5 or 0.7 mm in diameter, that transfers the ink from the reservoir onto the paper as the pen moves.

There are two main types of roller ball pens: liquid ink pens and gel ink pens. The 'liquid-ink' type uses an ink and ink supply system similar to a fountain pen, and they are designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen. The 'liquid-ink' type rollerball pens were introduced in 1963 by the Japanese company Ohto. [2] [3] The gel ink type rollerball pens were patented in 1982 by Sakura Color Products. [2]

Gel inks usually contain pigments, while liquid inks are limited to dyestuffs, as pigments will sink down in liquid ink (sedimentation). The thickness and suspending power of gels allows the use of pigments in gelled ink, which yields a greater variety of brighter colors than is possible in liquid ink. Gels also allow for the use of heavier pigments with metallic or glitter effects, or opaque pastel pigments that can be seen on dark surfaces.

Liquid ink roller ball pens flow extremely consistently and skip less than gel ink pens do. The lower viscosity of liquid ink increases the likelihood of consistent inking of the ball, whereas the higher viscosity of gel ink produces "skipping", that is, occasional gaps in lines or letters.

Standards

The International Organization for Standardization has published standards for roller ball pens:

ISO 14145-1
1998: Roller ball pens and refills – Part 1: General use [4]
ISO 14145-2
1998: Roller ball pens and refills – Part 2: Documentary use (DOC) [5]

To comply to the ISO 14145-2:1998 documentary use standard the following has to be established by an ISO/IEC 17025 accredited laboratory:

Most roller ball refills comply to the ISO 14145-2:1998 standard and are approved for documentary use.

Uses

Former MI-6 agent Richard Tomlinson alleges that Pentel Rolling Writer roller ball pens were extensively used by SIS agents to produce secret writing (invisible messages) while on missions. [7]

The Ohto Model CB-10F Ceramic Roller Ball Pen was used at the 1990 Economic Summit of Industrialized Nations. [8]

<span class="mw-page-title-main">Ballpoint pen</span> Device dispensing ink over a metal ball at its point

A ballpoint pen, also known as a biro, ball pen, or dot pen, is a pen that dispenses ink over a metal ball at its point, i.e., over a "ball point". The metals commonly used are steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre.

<span class="mw-page-title-main">Ink</span> Liquid or paste that contains pigments or dyes

Ink is a gel, sol, or solution that contains at least one colorant, such as a dye or pigment, and is used to color a surface to produce an image, text, or design. Ink is used for drawing or writing with a pen, brush, reed pen, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing.

Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals.

<span class="mw-page-title-main">Fountain pen</span> Writing implement with nib and internal ink reservoir

A fountain pen is a writing instrument that uses a metal nib to apply water-based ink, or special pigment ink—suitable for fountain pens—to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir through a feed to the nib and deposits the ink on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism that creates suction or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges.

<span class="mw-page-title-main">Pen</span> Writing and drawing implement using liquid or paste ink

A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity that had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens. Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing.

<span class="mw-page-title-main">Dip pen</span> Writing instrument

A dip pen is a writing instrument used to apply ink to paper. It usually consists of a metal nib with capillary channels like those of fountain pen nibs, mounted in a handle or holder, often made of wood. Other materials can be used for the holder, including bone, metal and plastic; some pens are made entirely of glass.

A writing implement or writing instrument is an object used to produce writing. Writing consists of different figures, lines, and or forms. Most of these items can be also used for other functions such as painting, drawing and technical drawing, but writing instruments generally have the ordinary requirement to create a smooth, controllable line.

The Parker Jotter is the Parker Pen Company's second and best-selling retracting refillable ballpoint pen. The first was the Hopalong Cassidy ballpoint.. Since 1954, over 750 million have been sold worldwide. It is priced between $6 for lower end models, and $20 for higher end models, such as special editions. Its refill has a ballpoint tip originally called the T-Ball, with a unique textured surface that greatly reduces slipping and failure to transfer ink onto slick paper, known as "skipping." The technology is now commonly used in the pen industry. The pens are also a popular advertising medium. The external design of the Parker T-Ball refill is a configuration copied by many other brands of refillable pens.
