Although Japanese environmental regulations, and health and safety laws set tolerance levels for noise and vibration generated by printing presses, maintaining these levels in web offset presses are becoming increasingly difficult. This is particularly true in terms of noise, as today's presses tend to be larger and provide faster running speeds for the purpose of improving productivity. The most effective means for reducing noise levels is to enclose the entire web press or the printing unit and folder sections of the press in soundproofing barriers. Laying the proper foundation to support the press is essential for minimizing vibration of buildings within the printing plant. Mechanically induced problems with the press can lead to excessive noise and vibration, and daily maintenance is also necessary to protect the press equipment and alleviate these problems.
