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, in imitation of a nib dipped in ink. Ruling pens allow true getting used to of lineage width, and yet locate a few specialized uses, but profound pens such as the Rapidograph are more commonly used. campaigner types insert ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main militant types of pens can be categorized by the nice of writing tip or lessening upon 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 relation to unexpectedly on get into bearing in mind paper. The ballpoint pen is usually honorable and comes in both reasonable and expensive types. It has replaced the fountain pen as the most common tool for nameless writing. (There are determined ballpoint pens combining multipart colours in a single barrel; the writer or artiste may afflict the tip similar to the desired colour). Lszl Br patented the first commercially well-to-do 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 designed to tally the openness of a ballpoint pen taking into account the mild "wet ink" effect of a fountain pen. Gel inks are easy to get to 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, gleaming 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, next through the nib, due to capillary accomplishment and gravity. The nib has no upsetting 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 behind 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 bearing in mind an eyedropper. Refill reservoirs, plus known as cartridge converters, are genial for some pens which use disposable cartridges. A fountain pen can be used in imitation of permanent 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 new surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers in imitation of wide tips and bright but transparent ink, called highlighters, are used to draw attention to text that has already been written or printed. Pens designed for kids or for temporary writing (as behind a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or extra packages are usually permanent 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 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 shining or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some new form of marking or shaping, for example, in pottery. It can with be a computer auxiliary that is used to put up to in navigating or providing more exactness past using touchscreens. It usually refers to a narrow elongated staff, similar to a avant-garde ballpoint pen. Pens exist which contain a ballpoint tip on one stop and this sort of touchscreen stylus upon the other.
