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, like a nib dipped in ink. Ruling pens allow exact getting used to of pedigree width, and nevertheless locate a few specialized uses, but puzzling pens such as the Rapidograph are more commonly used. protester types affix ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main radical 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 nearly quickly upon get into past paper. The ballpoint pen is usually honorable and comes in both within your means and expensive types. It has replaced the fountain pen as the most common tool for dull writing. (There are determined ballpoint pens combining combined colours in a single barrel; the writer or artist may upset the tip in the same way as the desired colour). Lszl Br patented the first commercially successful ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip thesame 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 enhance the ease of use of a ballpoint pen later than the mild "wet ink" effect of a fountain pen. Gel inks are genial in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, vivacious shades, shady colors, invisible ink, see-through effect, bright colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become easy to use 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 put-on and gravity. The nib has no distressing 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 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 with an eyedropper. Refill reservoirs, moreover known as cartridge converters, are easy to get to for some pens which use disposable cartridges. A fountain pen can be used like enduring 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 children for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often upon other surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers past wide tips and shining but transparent ink, called highlighters, are used to heighten text that has already been written or printed. Pens expected for kids or for the theater writing (as gone a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or additional 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 up more suitably 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 small tool for some additional form of marking or shaping, for example, in pottery. It can afterward be a computer accessory that is used to incite in navigating or providing more accurateness considering using touchscreens. It usually refers to a narrow lengthy staff, thesame to a modern ballpoint pen. Pens exist which contain a ballpoint tip upon one end and this sort of touchscreen stylus upon the other.
