【Abstract】 With the development of digital technologies such as computer and network technology, printing has witnessed a change from traditional analog technics to digital production. Digital proofing technology has become a key technology in the digital printing processes and will become the mainstream of proofing technology. The purpose is to study on the technologic parameters of digital proofing, obtain the optimized technologic parameters of digital proofing , ensure the precise simulation from printing sample to digital proofing, promote the development of digital proofing technology.The main parameters in digital proofing technology were researched based on the color management, the printing chromatology and printing technology combining with the content of GATF digital test form. The single factor optimization was used to analyze the printer’s linearization, ICC Profile of printing and ICC Profile of proofing. The exact apparatuses ensure the precision of data. The mathematics models were established based on regression analysis.Based on the digital proofing software and equipments, the experiments were designed through the transform of technologic parameters. The relations between the densities and the dot areas were analyzed when the printer was checking linearity and the mathematics models were established. According to the request of research content, the digital proofing test form was designed. Via the experiments, the right ICC Profile of digital proofing was built and the optimized project was obtained. Make a summary of the reason which bring the differences by comparing with different ICC Profile.It has indicated: The O.R.I.S 5.1.2 proofing software accord with the Yule-Nielson Equation when checking linearity. The right ICC Profile of digital proofing could obtain by analyzing the Gray-balance data. The Dot-gain curves were conics. The different ICC Profile of printing could estimate the capability of the Gray-balance by analyzing color difference, the rule could guide production.更多还原
