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, next a nib dipped in ink. Ruling pens allow truthful adaptation of origin width, and yet locate a few specialized uses, but perplexing pens such as the Rapidograph are more commonly used. objector types increase ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main liberal 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 going on for rudely upon entry following paper. The ballpoint pen is usually well-behaved and comes in both inexpensive and costly types. It has replaced the fountain pen as the most common tool for undistinguished writing. (There are definite ballpoint pens combining combined colours in a single barrel; the writer or artiste may depress the tip considering the desired colour). Lszl Br patented the first commercially thriving 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 expected to affix the ease of use of a ballpoint pen in the same way as the mild "wet ink" effect of a fountain pen. Gel inks are reachable in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, active shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become clear 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, then through the nib, due to capillary piece of legislation 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 as soon 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 subsequently an eyedropper. Refill reservoirs, also known as cartridge converters, are handy for some pens which use disposable cartridges. A fountain pen can be used subsequent to unshakable or non-permanent inks.
A felt-tip pen, or marker, has a permeable 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 new surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers past broad tips and bright but transparent ink, called highlighters, are used to play up text that has already been written or printed. Pens designed for children or for interim writing (as following a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or supplementary packages are usually unshakable 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 handily upon 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 come 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 plus be a computer accessory that is used to support in navigating or providing more accurateness similar to using touchscreens. It usually refers to a narrow extended staff, same to a avant-garde ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus on the other.
