A pen is a common writing instrument used to apply ink to a surface, usually paper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, behind a nib dipped in ink. Ruling pens allow correct getting used to of descent width, and nevertheless find a few specialized uses, but rarefied pens such as the Rapidograph are more commonly used. advocate types add together ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main innovative types of pens can be categorized by the kind of writing tip or lessening upon the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries as regards snappishly on admission in imitation of paper. The ballpoint pen is usually trustworthy and comes in both reasonable and costly types. It has replaced the fountain pen as the most common tool for run of the mill writing. (There are certain ballpoint pens combining multipart colours in a single barrel; the writer or performer may sadden the tip as soon as the desired colour). Lszl Br patented the first commercially thriving ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip thesame 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 expected to affix the ease of understanding of a ballpoint pen later than the serene "wet ink" effect of a fountain pen. Gel inks are easily reached in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, active shades, shady colors, invisible ink, see-through effect, gleaming colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become easily reached using cartridges of fountain pen ink.
A fountain pen uses water-based liquid ink delivered through a nib. The ink flows from a reservoir through a "feed" to the nib, then through the nib, due to capillary law 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; the disposable type is called an ink cartridge. A pen next a refillable reservoir may have a mechanism, such as a piston, to pull ink from a bottle through the nib, or it may require refilling bearing in mind an eyedropper. Refill reservoirs, afterward known as cartridge converters, are easy to use for some pens which use disposable cartridges. A fountain pen can be used following steadfast or non-permanent inks.
A felt-tip pen, or marker, has a spongy tip of fibrous material. The smallest, finest-tipped felt-tip pens are used for writing on paper. Medium-tipped felt-tips are often used by children for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often on additional surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers once broad tips and shiny but transparent ink, called highlighters, are used to make more noticeable text that has already been written or printed. Pens meant for kids or for the theater writing (as gone a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or additional packages are usually surviving markers.
A gel pen uses ink in which pigment is suspended in a water-based gel. Because the ink is thick and opaque, it shows occurring more suitably on dark or smooth surfaces than the typical inks used in ballpoint or felt tip pens. Gel pens can be used for many types of writing and illustration. Gel pens often come in bright or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some new form of marking or shaping, for example, in pottery. It can plus be a computer accessory that is used to urge on in navigating or providing more correctness later using touchscreens. It usually refers to a narrow extended staff, similar to a forward looking ballpoint pen. Pens exist which contain a ballpoint tip on one end and this sort of touchscreen stylus upon the other.
