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, with a nib dipped in ink. Ruling pens permit truthful familiarization of lineage width, and still locate a few specialized uses, but rarefied pens such as the Rapidograph are more commonly used. futuristic types total ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main enlightened 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 small difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries nearly rapidly on log on afterward paper. The ballpoint pen is usually trustworthy and comes in both reasonable and expensive types. It has replaced the fountain pen as the most common tool for unsigned writing. (There are positive ballpoint pens combining combination colours in a single barrel; the writer or performer may hurt the tip considering 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 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 meant to tote up the ease of use of a ballpoint pen afterward 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, perky shades, shady colors, invisible ink, see-through effect, shiny colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become open 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 moving 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 in the manner of a refillable reservoir may have a mechanism, such as a piston, to pull ink from a bottle through the nib, or it may require refilling following an eyedropper. Refill reservoirs, in addition to known as cartridge converters, are understandable for some pens which use disposable cartridges. A fountain pen can be used with unshakable 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 with wide tips and bright but transparent ink, called highlighters, are used to draw attention to text that has already been written or printed. Pens expected for children or for the stage writing (as bearing in mind a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or extra packages are usually long-lasting 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 stirring more understandably 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 arrive in shining or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some supplementary form of marking or shaping, for example, in pottery. It can in addition to be a computer addition that is used to back in navigating or providing more truth later using touchscreens. It usually refers to a narrow lengthy staff, thesame to a militant ballpoint pen. Pens exist which contain a ballpoint tip on one stop and this sort of touchscreen stylus on the other.
