Pen types and Usage

Hello guys,

Today we are gonna be discussing and learning about Pen types and their intended usage.

The main modern types of pens can be categorized by the kind of writing tip or point:
  • A ballpoint pen dispenses ink by rolling a small hard sphere, usually 0.7–1.2 mm and made of brass, steel or tungsten carbide. The ink dries almost immediately on contact with paper. The ballpoint pen is usually reliable and come in both inexpensive and expensive types. The name Ballpoint is derived from the tip make- which looks and rolls like a ball. It is effective in writing on ordinary paper. It has replaced the fountain pen as the most common tool for everyday writing and scribbling.
          Ballpoint pens are mostly used by students and people whose work requires that they write consistently such as receptionists, accountants, secretaries, lecturers, teachers, etc.
  • A fountain pen uses water-based liquid ink delivered through a nib. The ink flows from a reservoir through a "feed" to the tip or nib, then through the nib, due to capillary action and gravity. The nib has no moving parts and delivers ink through a thin slit to the writing surface. A fountain pen reservoir can be refillable or disposable, this disposable type being an ink cartridge. A pen with a refillable reservoir usually do have a mechanism, such as a piston, to draw ink from a small container through the nib, or it may be refilled with an eyedropper. Refill reservoirs, also known as cartridge converters, are available for some pens which use disposable cartridges.

A fountain pen is most times used by artists and deigners for special designs especially Graphics.
  • A marker, or felt-tip pen, has a porous tip of fibrous material. The smallest, finest-tipped markers are used for writing on paper. Medium-tip markers are often used by children for coloring and drawing. Larger markers are used for writing on other surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers." Markers with wide tips and bright but transparent ink, called highlighters, are used to mark existing text. Markers designed for children or for temporary writing (as with a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or other packages are usually permanent markers.
  • A rollerball pen dispenses a water-based liquid or gel ink through a ball tip similar to that of a ballpoint pen. The less-viscous ink is more easily absorbed by paper than oil-based ink, and the pen moves more easily across a writing surface. The rollerball pen was initially designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen. Gel inks are available in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, vibrant shades, shady colors, invisible ink, see-through effect, shiny colors, and glow-in-the-dark effects.

What are Pens?

What are pens?

Pens are tools which are used in writing. They work by the use of ink which runs through a storage to a small opening.

Pens are mostly used to write on papers though there are special pens designed to write on other surfaces. For example, we have light pens which are electronic and works as an input device on computer screens.

Pens are also similar to pencils which are also used in writing on papers but contain a thread of lead as against ink which runs through Pens.

Pens can be used in writing on surfaces other than paper. Other surfaces on which pens can be used include wooden surfaces, clothes, plastic materials, cemented surfaces, metallic surfaces etc.

Pens come in various shapes, sizes and designs which are adapted to suit specific purposes. Therefore we have various types of pen from different manufacturers suited for different users.

My next discussion will be on Types of Pens and their expected users.

Have a great day ahead of you.
