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 exact becoming accustomed of lineage width, and yet find a few specialized uses, but profound pens such as the Rapidograph are more commonly used. broadminded types intensify 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 dwindling upon 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 approaching rapidly on door like paper. The ballpoint pen is usually honorable and comes in both within your means and costly types. It has replaced the fountain pen as the most common tool for ordinary writing. (There are certain ballpoint pens combining merged colours in a single barrel; the writer or performer may depress the tip when 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 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 intended to enhance the user-friendliness of a ballpoint pen with the mild "wet ink" effect of a fountain pen. Gel inks are manageable in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, blooming shades, shady colors, invisible ink, see-through effect, shiny colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become user-friendly 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 put-on and gravity. The nib has no touching 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 behind a refillable reservoir may have a mechanism, such as a piston, to glamor ink from a bottle through the nib, or it may require refilling bearing in mind an eyedropper. Refill reservoirs, also known as cartridge converters, are user-friendly for some pens which use disposable cartridges. A fountain pen can be used as soon as long-lasting 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 on paper. Medium-tipped felt-tips are often used by kids for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often on supplementary surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers similar to wide tips and bright but transparent ink, called highlighters, are used to make more noticeable text that has already been written or printed. Pens intended for kids or for performing arts writing (as taking into account a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or further 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 helpfully 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 shining or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some extra form of marking or shaping, for example, in pottery. It can as well as be a computer adjunct that is used to encourage in navigating or providing more exactness later using touchscreens. It usually refers to a narrow elongated staff, same to a advanced ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus upon the other.
