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 control the amount of light that passes through the LCD and that exposes red (R), green (G), and blue (B) films.
