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 allow exact adaptation of stock width, and nevertheless locate a few specialized uses, but profound pens such as the Rapidograph are more commonly used. advocate types insert ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main protester types of pens can be categorized by the kind of writing tip or lessening 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 rudely upon edit later paper. The ballpoint pen is usually honorable and comes in both reasonably priced and expensive types. It has replaced the fountain pen as the most common tool for unspecified writing. (There are distinct ballpoint pens combining combination colours in a single barrel; the writer or player may hurt the tip subsequently 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 designed to add up the user-friendliness of a ballpoint pen as soon as the smooth "wet ink" effect of a fountain pen. Gel inks are approachable in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, booming shades, shady colors, invisible ink, see-through effect, gleaming 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, next through the nib, due to capillary achievement and gravity. The nib has no distressing 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 consideration 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 when an eyedropper. Refill reservoirs, after that known as cartridge converters, are affable for some pens which use disposable cartridges. A fountain pen can be used bearing in mind 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 kids 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 wide tips and gleaming but transparent ink, called highlighters, are used to draw attention to text that has already been written or printed. Pens designed for kids or for temporary writing (as later 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 comprehensibly on 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 gleaming or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some new form of marking or shaping, for example, in pottery. It can then be a computer auxiliary that is used to urge on in navigating or providing more exactness taking into consideration 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 stop and this sort of touchscreen stylus on the other.
