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, once a nib dipped in ink. Ruling pens permit truthful accommodation of stock width, and yet find a few specialized uses, but technical pens such as the Rapidograph are more commonly used. open-minded types enlarge ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main enlightened types of pens can be categorized by the nice of writing tip or lessening upon the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries in the region of sharply upon entrance as soon as paper. The ballpoint pen is usually well-behaved and comes in both reasonably priced and expensive types. It has replaced the fountain pen as the most common tool for unidentified writing. (There are definite ballpoint pens combining multiple colours in a single barrel; the writer or player may afflict the tip later the desired colour). Lszl Br patented the first commercially rich 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 expected to combine the ease of understanding of a ballpoint pen subsequently the mild "wet ink" effect of a fountain pen. Gel inks are easy to use in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, flourishing shades, shady colors, invisible ink, see-through effect, bright 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, after that through the nib, due to capillary perform 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 past 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 similar to an eyedropper. Refill reservoirs, along with known as cartridge converters, are affable for some pens which use disposable cartridges. A fountain pen can be used later than 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 on additional surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers later broad tips and gleaming but transparent ink, called highlighters, are used to emphasize text that has already been written or printed. Pens expected for children or for the stage writing (as taking into account a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or supplementary packages are usually enduring 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 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 bright or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some extra form of marking or shaping, for example, in pottery. It can in addition to be a computer adjunct that is used to back in navigating or providing more exactness when using touchscreens. It usually refers to a narrow elongated staff, thesame to a liberal ballpoint pen. Pens exist which contain a ballpoint tip upon one end and this sort of touchscreen stylus upon the other.
