In the early nineties, Mark Weiser, a chief scientist at the Xerox Palo Alto Research Center (PARC), wrote a series of seminal papers that introduced the concept of Ubiquitous Computing. Within this vision, computers and others digital technologies are integrated seamlessly into everyday objects and activities, hidden from our senses whenever not used or needed. An important facet of this visio...

The work is framed within Printed Electronics, an emerging technology for the manufacture of electronic products. Among different printing methods, roll-to-roll flexography technique used because it allows continuous manufacturing and high productivity at low cost. Apart from process parameters, ink substrate properties are some variables associated with flexographic printing. Specifically, thi...

However, to become a leading one-stop solution provider support all packaging requirements from global clients, they must invest in new technology for business development strategy. This study focused on the challenges faced by food converter, Company A using flexography Koenig & Bauer as first Asian country that invests with enable them define yardsticks sector. also discussed strategies m...

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Abstract UV-readable fluorescent ink formulations find versatile applications in various fields including information encryption, automated identification systems, security markers and optical devices. In this context , a new bithiophene-based chalcone (BTCF) that exhibits good solution phase solid-state fluorescence was synthesized as colourant for formulating an eco-friendly UV ink. The molec...

The purpose of this study is to see if it is viable to use Optical Character Recognition (OCR) to determine legibility of non-western languages. The results will show that OCR can be used to inspect defects in order to waste fewer products. A large amount of waste is an issue in pharmaceutical printing due to the need for products to be one hundred percent accurate. Waste increases with non-wes...

Exploring processes for industrial large-scale manufacture of low-cost electronic devices is timely the upcoming era Internet Things. In this study, a roll-to-roll process using selective metallisation (a combination flexographic printing an oil liquid-mask and physical vapour deposition: sputtering evaporation) explored flexible electronics, with wearable thermoelectric generator as exemplar d...

Previous work (Gane, P.A.C. and Ridgway, C.J., Advances in Printing Science and Technology Volume 27, 2001) has shown that the absorption of the fluid phase from a waterbased flexographic ink is affected by the polymer content in the fluid phase, filtercake formation within the contacting ink layer and the distribution of dissolved polymer between the filtercake and the coating structure. The s...

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...
