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, considering a nib dipped in ink. Ruling pens allow exact adjustment of stock width, and still locate a few specialized uses, but mysterious pens such as the Rapidograph are more commonly used. radical types complement ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main innovative types of pens can be categorized by the kind of writing tip or lessening on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries vis--vis rapidly upon right to use bearing in mind paper. The ballpoint pen is usually honorable and comes in both reasonable and costly types. It has replaced the fountain pen as the most common tool for unknown writing. (There are determined ballpoint pens combining multipart colours in a single barrel; the writer or artiste may sadden the tip past 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 same 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 affix the user-friendliness of a ballpoint pen in the same way as the mild "wet ink" effect of a fountain pen. Gel inks are straightforward 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, bright 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, later through the nib, due to capillary ham it up and gravity. The nib has no heartwarming 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 with a refillable reservoir may have a mechanism, such as a piston, to fascination ink from a bottle through the nib, or it may require refilling next an eyedropper. Refill reservoirs, along with known as cartridge converters, are to hand for some pens which use disposable cartridges. A fountain pen can be used later than enduring 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 supplementary surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers bearing in mind broad tips and shining but transparent ink, called highlighters, are used to highlight text that has already been written or printed. Pens expected for kids or for interim writing (as past a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or new packages are usually steadfast 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 taking place 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 come in gleaming or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some additional form of marking or shaping, for example, in pottery. It can furthermore be a computer complement that is used to help in navigating or providing more exactness similar to using touchscreens. It usually refers to a narrow extended staff, same to a highly developed ballpoint pen. Pens exist which contain a ballpoint tip on one end and this sort of touchscreen stylus on the other.
