Devise creative ways to hide the ink out of sight, and see if X-rays can uncover it.

Electric Paint isn't the first conductive ink out there, with other products like rollerball pens also able to draw working circuits.

Radical Matter features contemporary designers making dye out of seaweed, and ink out of cat hair and even compressed car exhaust.

Is using light and mirrors better than just sending a picture to a printer over Bluetooth or Wi-Fi and blasting the ink out from a cartridge?

I took it out and I took his worn pen out of its holder, and I mixed ink out of the ashes in the fireplace and I made a list.

We got Ink out at a party for Ethika underwear when he began raving about the record-breaking Oklahoma freshman, who Ink says is his favorite basketball player on the planet.

Murray can squeeze ink out of a nib like juice from a lemon, dilating the paper with quick jabs of carbon and water, the building blocks of life, until it bulges and breathes.

From creating ink out of algae to "growing" leather in the lab using living DNA, there's a whole cadre of artists, scientists, designers, biohackers, and other makers using the biological sciences to make a more environmentally sustainable (and squishier!) society.

Instead of relying on gravity, they have special pressurized cartridges that use nitrogen gas to push ink out, which means they can write at any angle or in extreme cold, or extreme heat, where an ink of a normal pen would get too thick or too thin to write.

Hard to tell, and it doesn't help that at the upper left there are also light tracings of loops, as if he were trying to coax ink out of a ball point pen, and a patch of crosshatching that looks like a doodle I drew at a meeting, last week, when I was bored.

The testing focused on sampling yields generated from typical business consumer printing applications. The judgment of total yield was defined by fade, marked by a depletion of ink in the cartridge, or automatic stop, caused by an "Ink Out" detection function.

They have a maximum length of 200 centimeters, but are often are only 100 centimeters in length. It has an ink sack near the cloaca, and discharges ink out of it when it feels alarmed. Its prey are squids, and fishes such as anchovies. It is oviparous, and lays planktonic eggs.

1918 illustration of a mimeograph machine. The mimeo machine (mimeograph) invented by Albert Blake Dick in 1884 used heavy waxed-paper "stencils" that a pen or a typewriter could cut through. The stencil was wrapped around the drum of the (manual or electrical) machine, which forced ink out through the cut marks on the stencil. The paper had a surface texture (like bond paper), and the ink was black and odorless.

It was discovered later that a proof could be taken on damped paper by filling the engraved lines with ink and wiping it off the surface of the plate. Pressure was then applied to push the paper into the hollowed lines and draw the ink out of them. This was the beginning of plate printing. This convenient way of proofing a niello saved the effort of producing a cast, but further implications went unexplored.

Dot gain is caused by ink spreading around halftone dots. Several factors can contribute to the increase in halftone dot area. Different paper types have different ink absorption rates; uncoated papers can absorb more ink than coated ones, and thus can show more gain. As printing pressure can squeeze the ink out of its dot shape causing gain, ink viscosity is a contributing factor with coated papers; higher viscosity inks can resist the pressure better.

However, within three years the price of the pen went from $12.50 to 50¢. The Reynolds Rocket Pen had a tiny ball bearing that let ink out only when pressed against the item you were writing on. In advertisements Reynolds claimed it had enough ink to 15 years without refilling. In 1947, in a publicity stunt to promote Reynolds' pens Milton Reynolds and William Odom announced they would beat Howard Hughes's around the world record.

The retractable pen was first invented and patented in 1888 by John J. Loud. However, the design was seen as imperfect and the retractable pen would not be marketed until sixty years later. Lazlo Biro and his brother Gyorgy Biro solved the technical problems of the first ball point by using thicker ink and an easier way to store it. This resulted in the use of capillary action which slowly pulled the ink out of the pen and onto the paper.

The titular antagonist known only as the Ink Thief (O'Brien) steals the power of imagination by sucking the "ink" out of books and drawings. At the start of the show, brother and sister Jim and Sam stumble upon his gothic world filled with Oobs, Bumps, and other imaginary creatures. During the course of the show, the children's friendship is tested as Jim gets seduced by the Ink Thief, whereas Sam fights to stop him. Each episode is peppered with plot-specific songs, giving the show a musical feel.

For more thoroughly cleaning iron gall ink out of a fountain pen, sequential flushes of the pen with water, diluted vinegar or citric acid (to flush out residual iron gall compounds), water, diluted ammonia (if needed to flush out residual colour dye stains), then finally water are often recommended. The colour dye in these modern iron gall formulas functions as a temporary colourant to make these inks clearly visible whilst writing. The ferro-gallic compounds through a gradual oxidation process cause an observable gradual colour change to grey/black whilst these inks completely dry and makes the writing waterproof. The colour-changing property of the ink also depends on the properties of the used paper.

For example: Arrayed Inkjet Apparatus (John G Martner patent 4468680, 1984 Exxon Research and Engineering Co) was invented after testing a Piezo DOD epoxied on the end of a piano wire 30 inches long and inserted into a ink fluid chamber leading to a nozzle. The tiny piezo either was pulling the wire in and out of the fluid chamber or transmitting a sound wave through the wire to impart acoustic energy into the fluid to fire a drop. The object of the invention was to build a printhead to reduce crosstalk (sound or any energy into closely placed nozzles for text printing). The two leading technologies for forcing ink out of a nozzle on demand are thermal DOD and piezoelectric DOD.

He seeks out the Wish Realm Apprentice, who is now blind. He reminds Henry of the responsibility that came with being the Author, and the quill appears his hand. When Henry returns to the castle, he uses the quill to suck the ink out of Cruella, but before he can write in the book, the Wish Realm Rumpelstiltskin takes the quill and book away from him and surprises Henry with a new ally: Sir Henry from the Wish Realm, who unlike his counterpart did make a deal with the Alternate Dark One. It appears that the Wish Realm Rumpelstiltskin wants Sir Henry to use the ink and the book to rewrite the story to give the Wish Realm Rumpelstiltskin the power he craves, and to keep the Guardian from taking possession of the Dagger.

A print head will contain several such nozzles, and will be moved across the page as paper advances through the printer. ; A Canon inkjet with CMYK cartridgesThermal DOD printing:Most consumer inkjet printers, including those from Canon (FINE Cartridge system, see photo), Hewlett- Packard, and Lexmark, use the thermal inkjet process. The idea of using thermal excitation to move tiny drops of ink was developed independently by two groups at roughly the same time: John Vaught and a team at Hewlett- Packard's Corvallis Division, and Canon engineer Ichiro Endo. Initially, in 1977, Endo's team was trying to use the piezoelectric effect to move ink out of the nozzle but noticed that ink shot out of a syringe when it was accidentally heated with a soldering iron. Vaught's work started in late 1978 with a project to develop fast, low-cost printing.
