本文以我们研究的彩色扩印微电脑控制自动测色与曝光系统,介绍彩色扩印的关键——测色、校色与曝光的原理、结构与关键技术。一、测色、校色与曝光原理曝光原理,本系统采用加色法三原色(红、绿、兰)依次分层曝光的原理。这种曝光原理的特点是,使用三片密度较大的原色(红、绿、兰)滤色片,以曝光时间来控制彩色相片的颜色。 In this paper, we study the color printer microcomputer control automatic color measurement and exposure system, introduces the key to color printing - color measurement, color correction and exposure of the principle, structure and key technologies. First, color measurement, color correction and exposure principle Exposure principle, the system uses three primary colors plus color (red, green, blue) in turn layered exposure principle. This exposure principle is characterized by the use of three denser color primary (red, green, blue) filters to control the color of the color in exposure time.
