In fact, the liquid ink won't dry or harden without it.

Scientists have discovered that suspending fragile 3D-printed structures in a Jello-like goo while the liquid ink hardens keeps them from warping or sagging.

When you introduce liquid ink to a body of water it gradually disperses into the open space like a cloud of smoke from a fire.
|
|
That's why researchers led by Thomas Angelini and Chris O'Bryan at the University of Florida developed a new material called an organogel that can support the liquid ink as it hardens.

Williams creates these utterly mesmerizing images by manipulating liquid ink within a body of water, a technique similar to the one employed by Macro Room in their Ink In Motion video project.

But there's this lag time between when the printer first squirts out the liquid ink, and when that ink solidifies — which presents a problem: how do you keep your structure from collapsing or bending before it fully hardens?

Liquid ink cartridge from Hewlett-Packard HP 845C inkjet printer HP Deskjet, an inkjet printer Inkjet printers operate by propelling variably sized droplets of liquid ink onto almost any sized page. They are the most common type of computer printer used by consumers.

Liquid ink electrostatic printers use a chemical coated paper, which is charged by the print head according to the image of the document.; The paper is passed near a pool of liquid ink with the opposite charge. The charged areas of the paper attract the ink and thus form the image. This process was developed from the process of electrostatic copying.

The choice of print technology has a great effect on the cost of the printer and cost of operation, speed, quality and permanence of documents, and noise. Some printer technologies do not work with certain types of physical media, such as carbon paper or transparencies. 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. Cheques can be printed with liquid ink or on special cheque paper with toner anchorage so that alterations may be detected.

Commonly made from stone, ceramic, or clay, an inkstone is used to grind the solid inkstick into liquid ink and to contain the ink once it is liquid. Chinese inkstones are highly prized as art objects and an extensive bibliography is dedicated to their history and appreciation, especially in China.

This extends the lifetime of a Tipp-Ex bottle. One must write with a ball point pen on top of Tipp-ex, as a liquid ink pen will smudge. Gel ink will require a few seconds to fully dry, but can be used if no ball point pen is available.

The ink is the most important element that determines the effect of the painting. The use of ink can date back to the ancient China. Traditionally, ink is used along with the ink slab and columnar congealed ink. But with the convenience of preserving liquid ink grows, nowadays people prefer the easier way of using ink.

These machines print or mark on products by contacting the product surface. They mostly use some letters made up of metal or rubber and ink media like liquid ink or a ribbon or solid ink etc. to make an impression. The letters are made offset, so while printing they give mirror image and straight print is obtained.

These dry very quickly by direct conversion of the liquid ink to a solid form, rather than by evaporation of liquid solvents from a mixture. Powerful () ultraviolet (UV) lamps have been used to rapidly cure the ink. This allowed lenticular images to be printed at high speed. In some cases, electron beam lithography has been used instead.

Color reproduction is very accurate, and because there is no heating the scale distortion is less than ±0.1%. (All laser printers have an accuracy of ±1%.) Worldwide, most survey offices used this printer before color inkjet plotters become popular. Liquid ink electrostatic printers were mostly available in width and also 6 color printing. These were also used to print large billboards.

The paper rolls were long. A metal bar above the take-up reel allowed a finished plot to be torn off and removed. The drum would then be advanced using the manual controls and the fresh paper end taped to the take-up reel. The standard pen was a ball-point, but liquid ink pens were available, and typically used for higher quality plots intended for publication.

Solid ink printers, also known as phase-change ink or hot-melt ink printers, are a type of thermal transfer printer, graphics sheet printer or 3D printer . They use solid sticks, crayons, pearls or granular ink materials. Common inks are CMYK-colored ink, similar in consistency to candle wax, which are melted and fed into a piezo crystal operated print-head. A Thermal transfer printhead jets the liquid ink on a rotating, oil coated drum.

CRTs with an unphosphored front glass but with fine wires embedded in it were used as electrostatic print heads in the 1960s. The wires would pass the electron beam current through the glass onto a sheet of paper where the desired content was therefore deposited as an electrical charge pattern. The paper was then passed near a pool of liquid ink with the opposite charge. The charged areas of the paper attract the ink and thus form the image.

Yatate literally means "quiver" ("ya-tate"). The name comes from the practice of early bushi who kept ink stones inside their quivers. Japanese writing was traditionally done using the writing set inspired from China: an inking stone, a small stick of solid ink (sumi) (which is turned to usable liquid ink by grinding on the inking stone and watering), and brushes. The complete set was easily portable and took time to prepare the materials for writing.

The darkening process of the ink is due to the oxidation of the iron ions from ferrous (Fe2+) to ferric (Fe3+) state by atmospheric oxygen. For that reason, the liquid ink needs to be stored in a well-stoppered bottle, and often becomes unusable after a time. The ferric ions react with the tannic acid or some derived compound (possibly gallic acid or pyrogallol) to form a polymeric organometallic compound. While a very effective ink, the formula was less than ideal.

Transparencies can be printed on laser printers or copiers. Specialist transparencies are available for use with laser printers that are better able to handle the high temperatures present in the fuser unit. For inkjet printers, coated transparencies are available that can absorb and hold the liquid ink – although care must be taken to avoid excessive exposure to moisture, which can cause the transparency to become cloudy; they must also be loaded correctly into the printer as they are only usually coated on one side.

Although pens with semi-flexible nibs and liquid ink can also vary their stroke width depending on the degree of applied pressure, their variation range is far less obvious. Traditionally, brushes have been loaded with ink by dipping the bristles into an external pool of ink on an inkstone, analogous to a traditional dip pen with an inkwell. Some companies now make "brush pens" which in that regard resemble a fountain pen, with an internal ink reservoir built into the handle which can be refilled with preloaded cartridges or a bottle-fill converter.

Recent advances in 3D printing have meant that there are several new techniques in PCB creation. 3D printed electronics (PEs) can be utilized to print items layer by layer and subsequently the item can be printed with a liquid ink that contains electronic functionalities. Manufacturers may not support component-level repair of printed circuit boards because of the relatively low cost to replace compared with the time and cost of troubleshooting to a component level. In board-level repair, the technician identifies the board (PCA) on which the fault resides and replaces it.

Because of the liquid-ink-spillage concern, solid-ink printers are not suitable for mobile usage, such as on movable carts for printing pricing tags in retail settings. Unlike some inkjet printers where the cartridge includes the print head, the printhead in these printers is fixed. Over time, parts of the printhead may become permanently clogged, resulting in unsightly streaks, but there are printhead and drum cleaning cycles and jet-substitution options which can resolve most printing issues. There is a filter for the ingested ink implemented at least on the recent ColorQube devices (8570/8870), according to a service manual for those models.

In CIJ technology, a high-pressure pump directs liquid ink from a reservoir through a gunbody and a microscopic nozzle (usually .003 inch diameter), creating a continuous stream of ink droplets via the Plateau- Rayleigh instability. A piezoelectric crystal may be used to create an acoustic wave as it vibrates within the gunbody and causes the stream of liquid to break into droplets at regular intervals: 64,000 to 165,000 droplets per second may be achieved. The ink droplets are subjected to an electrostatic field created by a charging electrode or by a magnetic flux field as they form; the field varies according to the degree of drop deflection desired.

Metal needles insert into the ink tanks to collect ink. The liquid inlet is a notch cut into the side of the needle, with a spring-loaded sliding rubber cap (shown) that slides up over the notch when the tank is removed. This design retains moisture inside the ink supply tubing and prevents dry-out and clogging when ink tanks are either not installed, or are removed for replacement. A continuous ink system (CIS), also known as a continuous ink supply system (CISS), a continuous flow system (CFS), an automatic ink refill system (AIRS), a bulk feed ink system (BFIS), or an off- axis ink delivery system (OIDS) is a method for delivering a large volume of liquid ink to a comparatively small inkjet printhead.
