Objetivo The objective of this project was the evaluation and demonstration of the use of PLZT ceramic light-gate arrays for: - high-performance xerographic printing - colour printing on colour-sensitive media.The objective of this project is the evaluation and demonstration of the use of lanthanum doped lead zirconate titanate (PLZT) ceramic light gate arrays for:high performance xerographic printing;colour printing on colour sensitive media.A 300 dpi prototype light gate array has been delivered and evaluated. It has been incorporated into a customized system and its usefulness in halftone photographic colour printing has been successfully demonstrated, with good uniformity and colour rendering. The device was later fitted into an electrophotographic engine and the tests demonstrated the feasibility of greyscale pictures, using a combination of pulsewidth modulation and spacial dithering. The print bar device showed excellent light transmission, a good contrast ratio (reaching 38:1) and fast switching properties. The basic potential of the PLZT technology has been proven by the project but a revison of the design of the first prototype device (for example, using embedded electrodes to produce a more uniform electrical field) seems necessary.The most important advantage of this electro-optic printing technology in comparison to the competing approaches (laser, LED, thermotransfer, LC array, ink-jet) is the unique combination it allows of several features: - 600 dpi resolution - colour printing potential - large area printing - high speed - grey shades possible - mass and professional applications equally possible.
