The gravure printing spot color proofing machine is designed and produced by imitating the Principle of the printing machine. The pressure of the proofing machine is adjustable and the range of substrates is wide. It is suitable for packaging and printing production, paper production enterprises, ink production enterprises and scientific research institutions. use. The spot color proofing machine can accurately predict . The correct ratio of the ink is determined by continuously comparing with the color of the standard sample. After the spot color is matched correctly, it will be mass-produced on the printing machine according to the ratio, so that the color matching work is completely transferred to the pre-press work.

Operation mode: touch screen control, automatic positioning, pneumatic pressing, avoiding errors caused by human operation.
Power configuration: Equipped with high-precision servo motor, using Japanese technology servo system
Embossing method: embossing in a circular way, which makes the fit between the pattern and the roller better.
The scraper is used for ink supply, and the gravure anilox roller is made by electric engraving or laser engraving, which has higher precision.
Equipped with a transmission cleaning device: it is more convenient to separate the mesh roller from the rubber roller and clean the mesh roller separately
Pre-press position adjustment: configure automatic reset sensor system
Anilox roller: different styles of anilox roller can be quickly replaced, and can also be customized according to customer requirements

Ink viscosity: (generally 3# cup 15-20 seconds viscosity), low viscosity may cause tearing phenomenon, low viscosity can adjust the speed to match.
Squeegee adjustment: Lines appear in the printed color sample because the scraper is not locked. If lines appear in the blank area, it is caused by scraper chipping. It may be necessary to adjust or replace the scraper.
Pressure control: If there are pinholes in the printed color sample, adjust the pressure to increase a little bit. If there are creases or tears in the color sample, reduce the pressure appropriately. To prevent the static electricity of the film from absorbing dust and affecting the printing effect, pay attention to the Operating Environment.
