چکیده
Captive continuous inkjet (CIJ) is a potentially disruptive inkjet technology recently developed in the Kodak Technology Center. The captive continuous inkjet technology is expected to deliver the best of both drop-on-demand (DOD) inkjet and continuous inkjet (CIJ) technologies: high resolution, compact size, and low cost associated with traditional DOD technologies and the high throughput and high reliability of traditional CIJ technology. In this paper, we will provide a description of this new architecture, its function and why we believe it to be advantaged over both traditional CIJ and DOD technologies. We will discuss the key technology elements with details on the design, fabrication, and characterization of captive CIJ devices, including results from simulations and experimental studies. Introduction Captive continuous inkjet (CIJ) technology uses the momentum of an internal captive continuous ink flow in combination with a deflection mechanism to generate print drops by deflecting the internal flow out of a relatively large opening.[1,2,3,4,5] In operation, the continuous internal flow gives rise to drops with a momentum similar to other continuous inkjet technologies, and removes the firing frequency limitations that are associated with the capillary refill mechanism of typical DOD technologies. Also, unlike other continuous inkjet technologies, the fluid deflection mechanism is only employed when a print drop is required so there is no need for drop sorting after drop formation. These characteristics should translate into advantages in image quality, print speed, system cost, and ejector reliability.

Direct printing of functional electronic materials may provide a new route to low-cost fabrication of integrated circuits. However, to be useful it must allow continuous manufacturing of all circuit components by successive solution deposition and printing steps in the same environment. We demonstrate direct inkjet printing of complete transistor circuits, including via-hole interconnections ba...
متن کاملLow temperature fabricated conductive lines on flexible substrate by inkjet printing
The optimal conditions of inkjet-printed nano-silver suspension and silver nitrate solution for fabricating continuous narrow conductive lines on a polyimide substrate are investigated. In addition, the effects of driving pulse voltage and droplet coverage on the bulging of as-printed conductive lines are also examined.
