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, gone a nib dipped in ink. Ruling pens allow truthful familiarization of heritage width, and nevertheless locate a few specialized uses, but technical pens such as the Rapidograph are more commonly used. open-minded types count up ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main open-minded types of pens can be categorized by the nice of writing tip or point 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 in this area suddenly on way in gone paper. The ballpoint pen is usually obedient and comes in both reasonable and expensive types. It has replaced the fountain pen as the most common tool for unnamed writing. (There are certain ballpoint pens combining compound colours in a single barrel; the writer or artiste may sadden the tip when 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 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 meant to tally up the openness of a ballpoint pen past the mild "wet ink" effect of a fountain pen. Gel inks are friendly in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, busy shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become welcoming 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 be active and gravity. The nib has no disturbing 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 pull ink from a bottle through the nib, or it may require refilling similar to an eyedropper. Refill reservoirs, plus known as cartridge converters, are affable for some pens which use disposable cartridges. A fountain pen can be used next remaining 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 upon 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 in the manner of wide tips and gleaming but transparent ink, called highlighters, are used to put the accent on text that has already been written or printed. Pens designed for children or for performing writing (as later 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 sleek 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 come in bright or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some new form of marking or shaping, for example, in pottery. It can along with be a computer supplement that is used to urge on in navigating or providing more truth later than using touchscreens. It usually refers to a narrow extended staff, similar to a militant ballpoint pen. Pens exist which contain a ballpoint tip upon one end and this sort of touchscreen stylus on the other.
