A display color reproduction method of network printing client based on form was put forward through study of computer network technology and the printing color management technology. The color display data of client was obtained by using client observation and form data on the base of the display color of the network client; Client display color WYSIWYG was realized by calculation and reproduction of color data. The experiment showed that the method can solve the problem of color reproduction of network printing client display, improve network printing quality, shorten cycle, reduce cost, and improve network printing efficiency.
