Application:
HK-310 Offset ink proofer (offset printing proofer) is to imitate the working principle of the design and production of the printing, 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.

Spot Color Ink is relative to the traditional CMYK four-color ink. It refers to a new ink prepared by mixing one or more than two inks together with certain auxiliary materials. Make it suitable for printing needs and color requirements. The color gamut of spot color performance is largely beyond the range of RGB and CMYK color gamuts. Many colors that cannot be represented by CMYK four-color printing inks can be realized with spot color inks.

Because spot color printing uses large-area solid color blocks to print colors, the color effect is good, and the color difference caused by dot overprinting and dot deformation is reduced. The color is stable and the color gamut is wide. Therefore, in order to achieve special artistic effects in cigarette labels, wine labels, and packaging products, spot color inks are widely used for printing. Spot color printing can not only solve the problems of four-color printing due to overprinting and ink balance, but also meet the quality requirements of innovative design, and the ink balance in the printing process is also relatively easy to control.

There are many factors that produce color difference in spot color ink printing, but the main ones are: material performance, ink properties, printing conditions, and surface finishing of printed matter. These factors will affect the color reproduction in the spot color printing process.
