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 permit precise getting used to of line width, and nevertheless find a few specialized uses, but highbrow pens such as the Rapidograph are more commonly used. enlightened types improve ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main liberal 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 little hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries on the order of gruffly on gain access to afterward paper. The ballpoint pen is usually well-behaved and comes in both within your means and expensive types. It has replaced the fountain pen as the most common tool for unidentified writing. (There are distinct ballpoint pens combining combined colours in a single barrel; the writer or performer may afflict the tip taking into account 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 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 expected to enlarge the ease of access of a ballpoint pen with the serene "wet ink" effect of a fountain pen. Gel inks are welcoming 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 easy to get to 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 take effect and gravity. The nib has no upsetting 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 similar to a refillable reservoir may have a mechanism, such as a piston, to attraction ink from a bottle through the nib, or it may require refilling in imitation of an eyedropper. Refill reservoirs, after that known as cartridge converters, are friendly for some pens which use disposable cartridges. A fountain pen can be used considering steadfast 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 additional surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers in imitation of wide tips and shiny but transparent ink, called highlighters, are used to play up text that has already been written or printed. Pens expected for children or for interim writing (as next a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or additional packages are usually surviving 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 conveniently on dark or slick 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 bright or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some extra form of marking or shaping, for example, in pottery. It can next be a computer auxiliary that is used to assist in navigating or providing more truthfulness afterward using touchscreens. It usually refers to a narrow extended staff, thesame to a futuristic ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus upon the other.
