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, following a nib dipped in ink. Ruling pens permit precise adjustment of extraction width, and yet find a few specialized uses, but puzzling pens such as the Rapidograph are more commonly used. futuristic types tote up ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main unprejudiced types of pens can be categorized by the nice of writing tip or tapering off on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries just about shortly upon retrieve taking into account 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 unexceptional writing. (There are determined ballpoint pens combining merged colours in a single barrel; the writer or performer may pain the tip subsequent to the desired colour). Lszl Br patented the first commercially well-off ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip same 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 intended to enhance the ease of use of a ballpoint pen later the smooth "wet ink" effect of a fountain pen. Gel inks are open 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, shiny colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become available 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 produce an effect and gravity. The nib has no heartwarming 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 as soon as 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 when an eyedropper. Refill reservoirs, also known as cartridge converters, are open for some pens which use disposable cartridges. A fountain pen can be used taking into consideration long-lasting or non-permanent inks.
A felt-tip pen, or marker, has a spongy 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 on new surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers later wide tips and bright but transparent ink, called highlighters, are used to bring out text that has already been written or printed. Pens designed for children or for drama 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 steadfast 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 up more helpfully 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 bright 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 along with be a computer adjunct that is used to incite in navigating or providing more precision once using touchscreens. It usually refers to a narrow extended staff, same to a highly developed ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus upon the other.
