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 manner of a nib dipped in ink. Ruling pens permit precise familiarization of origin width, and still locate a few specialized uses, but technical pens such as the Rapidograph are more commonly used. innovative types enhance ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main forward looking types of pens can be categorized by the nice of writing tip or reduction 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 all but shortly on read taking into account paper. The ballpoint pen is usually honorable and comes in both within your means and expensive types. It has replaced the fountain pen as the most common tool for undistinguished writing. (There are clear ballpoint pens combining merged colours in a single barrel; the writer or artist may afflict the tip behind the desired colour). Lszl Br patented the first commercially affluent 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 meant to put in the user-friendliness of a ballpoint pen behind 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, living shades, shady colors, invisible ink, see-through effect, shiny colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become easy to use 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 accomplish and gravity. The nib has no touching 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 later a refillable reservoir may have a mechanism, such as a piston, to charisma ink from a bottle through the nib, or it may require refilling later an eyedropper. Refill reservoirs, with known as cartridge converters, are straightforward for some pens which use disposable cartridges. A fountain pen can be used in imitation of unshakable or non-permanent inks.
A felt-tip pen, or marker, has a permeable 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 with broad tips and shiny but transparent ink, called highlighters, are used to put emphasis on text that has already been written or printed. Pens intended for kids or for interim writing (as following a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or extra packages are usually permanent 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 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 shiny or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some additional form of marking or shaping, for example, in pottery. It can furthermore be a computer adjunct that is used to incite in navigating or providing more precision considering using touchscreens. It usually refers to a narrow extended staff, thesame to a avant-garde ballpoint pen. Pens exist which contain a ballpoint tip on one stop and this sort of touchscreen stylus on the other.
