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 precise familiarization of origin width, and yet find a few specialized uses, but puzzling pens such as the Rapidograph are more commonly used. innovative types total ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main ahead of its time types of pens can be categorized by the nice of writing tip or reduction on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a small difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries in this area hastily upon door bearing in mind paper. The ballpoint pen is usually obedient and comes in both inexpensive and costly types. It has replaced the fountain pen as the most common tool for mysterious writing. (There are positive ballpoint pens combining multiple colours in a single barrel; the writer or performer may afflict the tip later the desired colour). Lszl Br patented the first commercially booming 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 designed to enhance the ease of understanding of a ballpoint pen as soon as the serene "wet ink" effect of a fountain pen. Gel inks are to hand in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, living shades, shady colors, invisible ink, see-through effect, shiny 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, later through the nib, due to capillary conduct yourself 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 in the same way as a refillable reservoir may have a mechanism, such as a piston, to charisma ink from a bottle through the nib, or it may require refilling gone an eyedropper. Refill reservoirs, as well as known as cartridge converters, are available for some pens which use disposable cartridges. A fountain pen can be used behind unshakable 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 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 upon other surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers in the same way as wide tips and shining but transparent ink, called highlighters, are used to emphasize text that has already been written or printed. Pens designed for children or for temporary writing (as in the manner of a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or further 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 in the works more simply upon 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 plus be a computer auxiliary that is used to support in navigating or providing more precision in imitation of using touchscreens. It usually refers to a narrow elongated staff, thesame to a broadminded ballpoint pen. Pens exist which contain a ballpoint tip upon one end and this sort of touchscreen stylus on the other.
