Abstract
A film exposure apparatus employs a liquid crystal display. The film exposure apparatus may reduce the film and plate fabrication cost and time required in a publication printing process and may also enhance printing quality. The apparatus may include an exposure device that illuminates the LCD. The LCD may display an image in one or more gray scales that may correspond to color concentrations in a document to be reproduced. The LCD may control the amount of light that passes through the LCD and that exposes red (R), green (G), and blue (B) films.
