Application: Offset printing spot color proofing machine is to imitate the working principle of the design and production of the press, the proofing machine pressure adjustable, a wide range of substrates for printing and packaging production, paper production enterprises, ink production enterprises and research institutions, and so on use. Spot color proofing research through standard proofing to accurately predict the hue of ink. Through the continuous comparison with the color of the standard to determine the correct ratio of ink, spot color deployment is correct and then in accordance with the ratio in the printing press on the mass production, making the color work completely into prepress work.
