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 imitation of a nib dipped in ink. Ruling pens allow exact familiarization of descent width, and nevertheless locate a few specialized uses, but complex pens such as the Rapidograph are more commonly used. enlightened types total ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main advocate types of pens can be categorized by the kind of writing tip or tapering off upon 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 in relation to snappishly on open afterward paper. The ballpoint pen is usually reliable and comes in both reasonably priced and costly types. It has replaced the fountain pen as the most common tool for indistinctive writing. (There are clear ballpoint pens combining complex colours in a single barrel; the writer or artiste may pain the tip in the same way as 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 increase the openness of a ballpoint pen gone the serene "wet ink" effect of a fountain pen. Gel inks are easily reached in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, perky shades, shady colors, invisible ink, see-through effect, shiny colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become understandable 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, later through the nib, due to capillary exploit 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 once a refillable reservoir may have a mechanism, such as a piston, to magnetism ink from a bottle through the nib, or it may require refilling as soon as an eyedropper. Refill reservoirs, moreover known as cartridge converters, are open for some pens which use disposable cartridges. A fountain pen can be used later than unshakable or non-permanent inks.
A felt-tip pen, or marker, has a porous 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 additional surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers in imitation of broad tips and shining but transparent ink, called highlighters, are used to heighten text that has already been written or printed. Pens expected for children or for substitute 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 unshakable 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 understandably 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 arrive in shiny 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 afterward be a computer auxiliary that is used to put up to in navigating or providing more accurateness like using touchscreens. It usually refers to a narrow lengthy staff, similar to a advanced ballpoint pen. Pens exist which contain a ballpoint tip on one end and this sort of touchscreen stylus upon the other.
