Methods and tools for fluid characterization, drop visualization and drop formation physics, as used at the Cambridge Inkjet Research Centre, are presented. Some recent results and interpretation for drop on demand inkjet printing of some model fluids and their implications for general inkjet fluids are also discussed.

Printing technologies specifically digital inkjet printing, offer possibilities in the production of individualized medicines. The main advantage of inkjet printing includes the ability to dispense uniform droplets in the picoliter range with high degree of accuracy to allow dose personalization. The pharmaceutical ink formulation has to be designed with respect to its viscosity and surface ten...

Introduction As a result of current advances in inkjet colour management and halftoning (Lee, 2005; Morovik, 2012) a significant impact of inkjet printing has meant that the artist can now take for granted highquality colour and resolution in their printed images. Now that the digital printing machine has reached a level where it is seemingly little more than a highly sophisticated image reprod...

In this study, a method to construct a full-colour volumetric display is presented using a commercially available inkjet printer. Photoreactive luminescence materials are minutely and automatically printed as the volume elements, and volumetric displays are constructed with high resolution using easy-to-fabricate means that exploit inkjet printing technologies. The results experimentally demons...

We are developing inkjet printing as a low cost, high throughput approach to the deposition of front contacts for Si solar cells. High deposition rates of 1μm per printing pass were achieved with a new metalorganic ink composed of silver(trifluoroacetate) in ethylene glycol. The printing conditions were optimized to achieve a relatively high line resolution of 120 μm. The optimal parameters for...

To broaden the scope of inkjet printing, this paper focuses on printing of an organic silver complex ink on glass substrates towards the fabrication of metallic 3D microstructures. The droplet formation sequence of the inkjet printer is optimised to print continuous layers of metal. A brief discussion on orientation trials, aimed at optimising the print parameters, is followed by two different ...

Application of Inkjet-Printing Technology to Micro-Electro-Mechanical Systems

A flexible proximity sensor fully fabricated by inkjet printing is proposed in this paper. The flexible proximity sensor is composed of a ZnO layer sandwiched in between a flexible aluminum sheet and a web-shaped top electrode layer. The flexible aluminum sheet serves as the bottom electrode. The material of the top electrode layer is nano silver. Both the ZnO and top electrode layers are depos...

We developed and characterized a novel picoliter droplet-in-oil array generated by a double-inkjet printing method on a uniform hydrophobic silicon chip specifically designed for quantitative polymerase chain reaction (qPCR) analysis. Double-inkjet printing was proposed to efficiently address the evaporation issues of picoliter droplets during array generation on a planar substrate without the ...

Inkjet printing of photographs using both dye-based and pigmented inks has become the most popular form of output from digital camera files. In addition to desktop and wideformat applications, inkjet printing technology is now also being adopted for “dry” minilabs and by professional portrait and wedding photography studios. Various factors affecting both light-induced and thermally-induced yel...
