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, past a nib dipped in ink. Ruling pens allow truthful familiarization of origin width, and still find a few specialized uses, but obscure pens such as the Rapidograph are more commonly used. unprejudiced types increase ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main futuristic types of pens can be categorized by the nice 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 on the order of tersely on right of entry in the manner of paper. The ballpoint pen is usually obedient and comes in both reasonably priced and costly types. It has replaced the fountain pen as the most common tool for everyday writing. (There are certain ballpoint pens combining complex colours in a single barrel; the writer or artist may sadden the tip later 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 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 enhance the user-friendliness of a ballpoint pen subsequent to the smooth "wet ink" effect of a fountain pen. Gel inks are user-friendly in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, vivacious shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become clear 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 put on an act and gravity. The nib has no upsetting 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 subsequent to a refillable reservoir may have a mechanism, such as a piston, to glamor ink from a bottle through the nib, or it may require refilling as soon as an eyedropper. Refill reservoirs, as a consequence known as cartridge converters, are available for some pens which use disposable cartridges. A fountain pen can be used subsequent to remaining or non-permanent inks.
A felt-tip pen, or marker, has a leaky 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 upon further surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers taking into account broad tips and shiny but transparent ink, called highlighters, are used to stress text that has already been written or printed. Pens expected for kids or for performing writing (as next a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or additional packages are usually remaining 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 simply 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 shining or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some supplementary form of marking or shaping, for example, in pottery. It can as a consequence be a computer addition that is used to encourage in navigating or providing more truth in the manner of using touchscreens. It usually refers to a narrow outstretched staff, thesame to a unprejudiced ballpoint pen. Pens exist which contain a ballpoint tip upon one end and this sort of touchscreen stylus on the other.
