Some Knowledge and Maintenance of Flexographic Printing Machines

How can conflicts be resolved during the operation of flexographic printing machines?

Flexographic printing can accept smaller orders because its printing plate cost is more economical and easier to replace than gravure printing drums. High resolution flexographic printing can achieve rapid replacement of printing operations, shorten the time cycle from design to printing, and these advantages bring more choices to packaging companies. Especially in the packaging market environment that emphasizes personalization, regionalization, and regular promotional activities, it can achieve printing of more complex colors, Improving the realism of images, making colors more attractive, brighter, and softer, packaging managers can use flexographic printing technology to achieve more eye-catching product effects and enhance the contrast between the product and the background color.

How to maintain flexographic printing machines?

1. Transmission: When subjected to printing pressure, multiple sets of gearboxes work quickly for a long time, which can cause gaps between the gearbox bearings and internal bearings, leading to a decrease in concentricity and affecting alignment accuracy. Thin knife machine

2. Unwinding and unwinding: The unwinding equipment should work at a constant speed and high speed under the pressure of the paper roll. Over time, the gap between the transmission gears will increase, which will affect the stability of the paper during the printing process.

3. Tension: The tension control system is an important equipment for ensuring printing alignment. The rapid operation of the equipment can lead to a decrease in registration accuracy, poor registration sensitivity, and large jitter.
