A second aspect of printer technology that is often forgotten is resistance to alteration: liquid ink, such as from an inkjet head or fabric ribbon, becomes absorbed by the paper fibers, so documents printed with liquid ink are more difficult to alter than documents printed with toner or solid inks, which do not penetrate below the paper surface.

The impact printer uses a print head that hits the surface of the ink ribbon, which presses the ink onto the paper.

The letter form strikes a ribbon of ink, depositing the ink on the page and thus printing a character.

As the color ribbon was used in the printer, the black ink section would gradually contaminate the other 3 colors, changing the consistency of printouts over the life of the ribbon.

** Dot matrix printer's ink ribbon

A printer / cassette interface was available, which used an ink ribbon on plain paper.

Another third party innovation was an add-on peripheral called the ThunderScan, which allowed the printer to work as a low-cost optical scanner ( the scanner mechanism temporarily replaced the ink ribbon cartridge ).

Typewriters and dot matrix printers use a cloth or plastic ribbon to hold the ink.

A dot matrix printer, for example, applies ink via tiny rods striking an ink ribbon, and has a relatively low resolution, typically in the range of 60 to 90 DPI.

Between the print head and the label is sandwiched a very thin thermal transfer ribbon ( or sometimes called " foil "), which is a polyester film which has been coated on the label side with a wax, wax-resin or pure resin " ink ".

As the label and ribbon are driven beneath the printhead together, tiny pixels across the width of the printhead are heated and cooled so as to melt the " ink " off the polyester film and onto the label.

The " ink " is designed to slightly dissolve into or adhere to the plastic surface of the label and becomes extremely durable, depending on the plastic material and ribbon make used.

As the paper and ribbon travel in unison beneath the thermal print head, the wax-based ink from the transfer ribbon melts onto the paper.

The word black comes from Old English blæc (" black, dark ", also, " ink "), from Proto-Germanic * blakkaz (" burned "), from Proto-Indo-European * bhleg-(" to burn, gleam, shine, flash "), from base * bhel-(" to shine "), related to Old Saxon blak (" ink "), Old High German blah (" black "), Old Norse blakkr (" dark "), Dutch blaken (" to burn "), and Swedish bläck (" ink ").

D. C. Thomson's other publications also suffered, with the Oor Wullie and The Broons annuals falling victim to paper and ink shortages.

Solid ink printers, also known as phase-change printers, are a type of thermal transfer printer.

Liquid ink electrostatic printers were mostly available in 36 inches to 54 inches width and also 6 color printing.

During this time he also started to experiment with ink and wash painting seen in work like Portrait of a Woman ( 1955 ) as well as creating portraits to illustrate the music surrounding him in Harlem.

Beyond ink and color on silk or paper scrolls, gold on lacquer was also a common medium in painted East Asian artwork.

There are also reports of ' indelible ' ink washing off voters ' fingers.

Baskerville also was responsible for significant innovations in printing, paper and ink production.

This press is also called an ink pyramid due to the fact that the ink is transferred through several layers of rollers with different purposes.

The shape of the stamp and the colour of the ink may also provide information about movements ( whether departure or arrival ).

Powders and pastes of calcium compounds were also used to help remove grease so the ink would not run.

A pen ( also called a stylus ) looks like a simple ballpoint pen but uses an electronic head instead of ink.

It also includes an ultraviolet light and changeable invisible ink nib for viewing messages written in the ultraviolet ink.

The Washington Times also used ink that it advertised as being less likely to come off on the reader's hands than the Posts.

Everyday objects such as abaci, benches, fans, ink brushes, smoking pipes, sewing needles, or various musical instruments, are also used by characters as weapons as well.

She also discovered that belemnite fossils contained fossilised ink sacs like those of modern cephalopods.

Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance, and ink is forced into the mesh openings of the mesh by the fill blade or squeegee and onto the printing surface during the squeegee stroke.

Monotypes can also be created by inking an entire surface and then, using brushes or rags, removing ink to create a subtractive image, e. g. creating lights from a field of opaque color.

Monoprints can also be made by altering the type, color, and viscosity of the ink used to create different prints.

He also invented carbon paper to provide the ink for his machine.

Process magenta ( the color used for magenta printing ink — also called printer's or pigment magenta ) is much less vivid than the color electric magenta achievable on a computer screen — indeed, CMYK printing technology cannot accurately reproduce pure magenta as described above as electric magenta ( 1 / 2 100 % blue light + 1 / 2 100 % red light = magenta ) on paper.

Blending is most easily done with a medium that does not immediately fix itself, such as graphite, chalk, or charcoal, although freshly applied ink can be smudged, wet or dry, for some effects.

Though ink does not easily cause death, inappropriate contact can cause effects such as severe headaches, skin irritation, or nervous system damage.

Over time, the ink is chemically stable and therefore does not threaten the strength of the paper.

In a carefully prepared quill the slit does not widen through wetting and drying with ink.

Copper is a traditional metal, and is still preferred, for etching, as it bites evenly, holds texture well, and does not distort the colour of the ink when wiped.

Zinc is cheaper than copper, so preferable for beginners, but it does not bite as cleanly as copper, and it alters some colours of ink.

Pigment is a finely ground, particulate substance which, when mixed or ground into a liquid to make ink or paint, does not dissolve, but remains dispersed or suspended in the liquid.

An intermediate method does exist: a disposable ink tank connected to a disposable head, which is replaced infrequently ( perhaps every tenth ink tank or so ).

Current carbon-dating technology does not permit the dating of samples as small as the actual ink lines on the map ….

Because the sublimated ink is a gas, it does diffuse a small amount before being absorbed by the paper.

The sheet is then fed through a dryer, which allows the inks to dry before moving on. In the case a UV ink is used, the sheet does not have to be dried, but is dried from UV rays.

One does not need to establish a private mail delivery service for the occasional commercial transport of a letter outside the mails so long as the rate which would have been due to the USPS is affixed in stamps, the stamps are cancelled in ink, and the date of receipt by the carrier or the transport of the letter, are noted thereon.

Multiple layers of gum are used after the etching process to build up a protective barrier that ensures the ink does not fill into the whitespace of the image being printed.

The erasable ink does not contain the toxic chemical compounds xylene and / or toluene, unlike permanent markers.

The $ 5 bill, however, does not feature color-shifting ink like all the other denominations.

The erasable ink does not contain the toxic chemical compounds xylene and / or toluene as have been used in permanent markers.

Because the coated surface does not absorb ink, erasable paper is apt to smudge.

The material in these erasers does not abrade ; once they are saturated with chalk or ink, the are cleaned by clapping them against a hard surface.

In many of the processes the ink or toner does not permeate the substrate, as does conventional ink, but forms a thin layer on the surface that may be additionally adhered to the substrate by using a fuser fluid with heat process ( toner ) or UV curing process ( ink ).
