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, in the same way as a nib dipped in ink. Ruling pens permit perfect becoming accustomed of pedigree width, and nevertheless locate a few specialized uses, but complex pens such as the Rapidograph are more commonly used. open-minded types improve ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main ahead of its time types of pens can be categorized by the kind of writing tip or point on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a small hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries approaching brusquely upon entry considering paper. The ballpoint pen is usually honorable and comes in both reasonable and costly types. It has replaced the fountain pen as the most common tool for secret writing. (There are positive ballpoint pens combining merged colours in a single barrel; the writer or artist may distress the tip once the desired colour). Lszl Br patented the first commercially wealthy ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip same 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 meant to increase the ease of access of a ballpoint pen like the mild "wet ink" effect of a fountain pen. Gel inks are affable in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, energetic shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become user-friendly 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, next through the nib, due to capillary work and gravity. The nib has no moving parts and delivers ink through a skinny slit to the writing surface. A fountain pen reservoir can be refillable or disposable; the disposable type is called an ink cartridge. A pen considering 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 subsequent to an eyedropper. Refill reservoirs, with known as cartridge converters, are manageable for some pens which use disposable cartridges. A fountain pen can be used considering permanent 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 kids for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often upon extra surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers similar to wide tips and shiny but transparent ink, called highlighters, are used to emphasize text that has already been written or printed. Pens intended for children or for performing arts writing (as in the manner of a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or supplementary 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 happening more usefully upon dark or sleek 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 along with be a computer accessory that is used to back up in navigating or providing more truth once using touchscreens. It usually refers to a narrow elongated staff, same to a modern ballpoint pen. Pens exist which contain a ballpoint tip on one end and this sort of touchscreen stylus upon the other.
