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 precise familiarization of lineage width, and still find a few specialized uses, but rarefied pens such as the Rapidograph are more commonly used. avant-garde types add together ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main radical types of pens can be categorized by the kind of writing tip or reduction on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries as regards snappishly upon admittance next paper. The ballpoint pen is usually reliable and comes in both reasonable and costly types. It has replaced the fountain pen as the most common tool for unexceptional writing. (There are sure ballpoint pens combining compound colours in a single barrel; the writer or performer may depress the tip afterward the desired colour). Lszl Br patented the first commercially well-to-do 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 designed to tally the ease of use of a ballpoint pen behind the mild "wet ink" effect of a fountain pen. Gel inks are friendly in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, animated shades, shady colors, invisible ink, see-through effect, gleaming colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become welcoming 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, subsequently through the nib, due to capillary operate and gravity. The nib has no heartwarming 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 taking into account a refillable reservoir may have a mechanism, such as a piston, to draw ink from a bottle through the nib, or it may require refilling in imitation of an eyedropper. Refill reservoirs, after that known as cartridge converters, are available for some pens which use disposable cartridges. A fountain pen can be used past remaining 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 upon paper. Medium-tipped felt-tips are often used by kids for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often upon other surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers in the manner of wide tips and bright but transparent ink, called highlighters, are used to play up text that has already been written or printed. Pens meant for children or for substitute writing (as bearing in mind a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or extra packages are usually long-lasting 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 up more handily upon dark or slick 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 arrive in gleaming or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some further form of marking or shaping, for example, in pottery. It can as well as be a computer addition that is used to support in navigating or providing more truth when using touchscreens. It usually refers to a narrow lengthy staff, same to a advocate ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus on the other.
