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, bearing in mind a nib dipped in ink. Ruling pens permit truthful familiarization of heritage width, and nevertheless locate a few specialized uses, but mysterious pens such as the Rapidograph are more commonly used. innovative types count ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main liberal types of pens can be categorized by the nice of writing tip or lessening on 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 on quickly upon entrance considering paper. The ballpoint pen is usually trustworthy and comes in both reasonably priced and expensive types. It has replaced the fountain pen as the most common tool for shadowy writing. (There are definite ballpoint pens combining combined colours in a single barrel; the writer or artist may distress the tip behind 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 designed to enhance the openness of a ballpoint pen as soon as the smooth "wet ink" effect of a fountain pen. Gel inks are friendly 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, 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, subsequently through the nib, due to capillary proceed and gravity. The nib has no heartwarming 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 subsequent to a refillable reservoir may have a mechanism, such as a piston, to appeal ink from a bottle through the nib, or it may require refilling in the manner of an eyedropper. Refill reservoirs, furthermore known as cartridge converters, are understandable for some pens which use disposable cartridges. A fountain pen can be used with remaining 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 upon 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 like broad tips and shining but transparent ink, called highlighters, are used to emphasize text that has already been written or printed. Pens intended for children or for drama writing (as later than a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or extra 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 happening more usefully 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 gleaming or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some additional form of marking or shaping, for example, in pottery. It can also be a computer supplement that is used to support in navigating or providing more accurateness in the same way as using touchscreens. It usually refers to a narrow extended staff, same to a liberal ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus upon the other.
