“Mead数字系统”公司研制了一种印刷系统。该系统每分钟能印刷50000行数字信息。系统的关键部分是用Corning公司的光敏玻璃制成的光敏玻璃陶瓷充电板,墨水流就是通过这块板导向目标的。充电板有512个精确定位的成形孔,其密度为100孔/英寸。充电板是非导体,但其上有一层金属镀层。板刚硬,坚固,且不渗透液体。 Mead Digital Systems developed a printing system. The system can print 50000 lines of digital information per minute. The key part of the system is a photosensitive glass ceramic charging plate made of Corning’s photosensitive glass through which ink flow is directed. The charging plate has 512 precisely-positioned holes with a density of 100 holes / inch. The charging board is non-conductive, but has a metal coating on it. The plate is stiff, strong and impermeable to liquids.
