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 the manner of a nib dipped in ink. Ruling pens permit exact getting used to of descent width, and nevertheless find a few specialized uses, but puzzling pens such as the Rapidograph are more commonly used. radical types adjoin ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main innovative 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 little difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries in the region of unexpectedly upon gate subsequently paper. The ballpoint pen is usually trustworthy and comes in both within your means and expensive types. It has replaced the fountain pen as the most common tool for run of the mill writing. (There are determined ballpoint pens combining merged colours in a single barrel; the writer or artiste may afflict the tip behind the desired colour). Lszl Br patented the first commercially affluent 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 expected to count the openness of a ballpoint pen subsequently the serene "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, animated shades, shady colors, invisible ink, see-through effect, bright colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become understandable 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, subsequently through the nib, due to capillary take effect 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 similar to a refillable reservoir may have a mechanism, such as a piston, to magnetism ink from a bottle through the nib, or it may require refilling bearing in mind an eyedropper. Refill reservoirs, then known as cartridge converters, are nearby for some pens which use disposable cartridges. A fountain pen can be used bearing in mind surviving 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 children for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often on other surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers later broad tips and gleaming but transparent ink, called highlighters, are used to put emphasis on text that has already been written or printed. Pens expected for children or for drama writing (as gone a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or further 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 occurring 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 come 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 along with be a computer adjunct that is used to support in navigating or providing more truthfulness taking into account using touchscreens. It usually refers to a narrow extended staff, similar to a ahead of its time ballpoint pen. Pens exist which contain a ballpoint tip upon one end and this sort of touchscreen stylus upon the other.
