We demonstrate ink-jet printing as a viable method for large area fabrication of graphene devices. We produce a graphene-based ink by liquid phase exfoliation of graphite in N-Methylpyrrolidone. We use it to print thin-film transistors, with mobilities up to about 95cm^2/V-s, as well as transparent and conductive patterns, with about 80 % transmittance and about 30kOhm/sq sheet resistance. This paves the way to all-printed, flexible and transparent graphene devices on arbitrary substrates

Technology Review – These guys have found a way to replace or augment the conducting polymers in these inks with graphene, the wonder-material of the moment. They’ve found a way to readily produced graphene by chemically chipping flakes off a block of graphite and filtering them to remove any that might clog the printer heads. They then add the flakes to a solvent called N-Methylpyrrolidone, or NMP, which minimises problems such as the coffee ring effect that can occur when some solvents evaporate. Finally they’ve put this stuff in their printers and printed out a few circuits and thin film transisters.
The results are promising. The graphene-based inks match or beat the performance of most other inks available today. That’s pretty good for a first attempt since improvements will certainly follow.

We demonstrated ink-jet printing of graphene. Liquid phase exfoliated graphene is an ideal and low cost material for the fabrication of transparent conductive inks. Our graphene-ink was used to print TFTs with mobility of up to about 95cm^2/V-s. It was also combined with PQT-12 to fabricate devices with mobility of about 0.2cm^2/V-s and ON/OFF ratios ∼4×10^5. This demonstrates the viability of graphene-inks for flexible and transparent electronics.

Engineers at the Oregon State University (OSU) have found a way to create successful CIGS – chalcopyrite – solar devices with inkjet technology which may  reduce raw material by 90 percent by creating precise patterning on the substrates and subsequently  lower cost of solar cell production. The cells could eventually  be high performing, ultra-low cost, rapidly produced and extremely thin.

According to the study, CIGS has extraordinary solar efficiency – a layer of chalcopyrite one or two microns thick has the ability to capture the energy from photons about as efficiently as a 50-micron-thick layer made with silicon. Current power conversion of a CIGS panel is about five percent, with potential to increase to 12 percent in the future. There’s also potential for future solar cells to be built directly into roofing materials with the inkjet technology.

While this technology is still in testing phase, it is a positive step in creating affordable renewable energy for home owners. Not only will the cells be less expensive, but because it uses less materials and hazardous materials, will also be much more environmentally friendly than traditional panels.

Until now, printing technology has been limited to laser and traditional inkjet systems. The Machjet represents an entirely new category of printing technology that makes possible high-quality color printing at never-before seen speeds and quality. Memjet’s ground-breaking, high-density page-wide printheads and components enable printers to operate twice as fast but at only half the cost to run versus traditional color office printers, on average.

“LG prides itself on launching truly innovative products and is pleased to bring the world’s fastest A4 color desktop printers powered by Memjet’s game-changing printing technology to the Korean market,” said Si-hwan Park, vice president of LG Electronics’ monitors and printers business unit. “The Machjet delivers completely new levels of color performance and affordability and uses significantly less energy versus laser printers.”

The Machjet leapfrogs over current printers with high-quality color outputs in 1600×800 dpi resolution at 60 pages per minute.Memjet’s proprietary Page Straight Array (PSA) Technology packs more than 70,000 ink nozzles on a single printhead—17 times the nozzle density of traditional printheads—allowing the Machjet to deliver more than 700 million drops of ink per second on a page.

Len Lauer, president and CEO of Memjet, said: “Combining Memjet’s core technology benefits with LG’s brand, corporate capabilities and vast distribution network, LG is creating exciting new value for Korean customers looking to be more efficient and cost effective in their office printing.”

Printers that are “powered by Memjet" are also energy efficient and less expensive to operate. While competitive color laser printers use on average approximately 600W of electricity during normal operations, the Machjet consumes just 32W. Costs are further reduced via the Machjet’s Hyper Small Drop Technology. The Machjet takes advantage of smaller droplets to minimize the amount of ink required to render clean, crisp text and images at high speed. This technology results in faster-drying ink and reduces the TCO (Total Cost of Ownership) by up to 70 percent when compared to competitive color laser printers.

Such innovation has given Memjet a significant intellectual property position in the industrywithmore than 3,000 approved global patents and another 2,000 pending.

SAN FRANCISCO — A US federal agency has backed its claim that rival MicroJet Technology Co. was infringing on patents for lucrative inkjet printer cartridges.

The (ITC) International Trade Commission issued a favourable "initial determination" regarding the validity of HP’s patents in the case, according to the California-based computer and printer maker.

HP on Friday said the ITC ruled that MicroJet infringed on HP patents while Asia Pacific Microsystems was a "contributory infringer."

Seiko Epson Corporation ("Epson," TSE: 6724) has today commenced High Court proceedings against Dynamic Cassette International Limited ("DCI") for infringement of several of its patents related to printer ink cartridge technology. DCI manufactures "own-brand" ink cartridges in the UK for a wide range of high street retailers and also sells under its own "Jet Tec" brand. Its infringing cartridges are sold in the UK and in many other countries.

Epson takes a proactive stance against infringements of this nature in order to protect its brand and technologies, and to support its channel partners and customers.

Maundy Thursday is the common name for Holy Thursday and marks the beginning of the three day celebrating of Easter.

Ok so what does this have to do with Inkjet Canada supplies ?

In Westminster Abbey, where in eight days time Prince William will wed fiancee Kate Middleton, the Queen presented the elderly with a token of gratitude – Maundy money.

The practice of distributing ”alms” to the needy or worthy on the Thursday of Holy Week dates back centuries and is an important annual event in the Queen’s calendar.

Metawatch is pleased to provide a rebate to anyone purchasing in excess of $50 (before taxes & shipping) of Inkjet Compatible supplies with (Maundy Money) a rebate of 5% for the next 3 days.

Here is what Google has to say

It’s tough to argue with Ben’s point, but as it turns out, a spike in searches around the two most significant events of tax season in the U.S.—the availability of W-2 forms and the due-date for federal tax returns—are pretty dependable as well, as search volume increases in January/beginning of February and in early April. Like other years, users have been looking for info on the process, places to turn for help, and service providers to get their taxes done. As expected, in the “Accounting & Tax” category, the fastest rising searches since mid-January include both commercial terms like [TurboTax] and [H&R Block] and government-specific terms like [IRS forms] and [1040 instructions].

Why is an inkjet company talking about taxes…..

Well just as searches are up so is printing…The average tax return in Canada is over 20 pages long, and there tends to be a lot of printing going in these days.

Live in Quebec….You can double those figures….

Fortunately Metawatch has a sale on at this time for its products so, if your printer is acting up these days, and you can hear it calling out for ink…Here is the place to shop.
