1. Precision roller presses error (beating), this will result in the same direction each packet of printed materials there is a difference. Is there any way to compensate for poor accuracy due to the machine caused by hue error?

     A: The printing press roller defects can not be other remedies, so to maintain the machinery in good condition; like you can not use the car factory in 1900, with the new car factory grounds as race.

     2. How do high-speed printing presses every hue control volumes ± 0.08 in the scope of the density change?

     A; machinery installation of automatic control and automatic adjustment function.

     3. Huangmei workshop every season or high humidity, temperature variation is often easier when the ink Deinking. Rollers on the condensed water to the plot, resulting in color changes in large or water, what measures can be taken to improve its ink water resistance?

     A: The ink itself is water resistant, drum on the condensed water is because there is no thermostat plant. The best way is to install air-conditioning plant and humidity system.

     4. Paper Paper gross (surface quality), resulting in leakage printed in ink transfer ink to add improved after oil, but they often also have a starting body, whether there are better ways to solve them?
