   Principle of spray humidification system: make the tap water pressurization by humidifier, through a special atomized nozzle, high-speed spray mist particles, and have the hot and wet exchange of air , take off the heat (or sensible heat)and evaporation,increase the humidity, implementation of air humidification.

   Printing quality is the life of printing enterprises, to ensure that, not only just need to have good printing equipments, materials, professional technology,but also a good relative humidity printing environment.It is a simple and effective method.Surface resistance decrease with the increase of air relative humidity, therefore, increasing the relative humidity can improve the electrical conductivity of papers, accelerating electric charge leaks.The best relative humidity should control between 55-65% RH.

   The changes of environmental temperature and humidity are the main factors of paper moisture content, once it changes, can cause paper deformation, crisp, printing quality misregister, fracture problems in the process of production.

   Papers will absorb moisture from other papers and humidity of wet air in the processs and drainage to the dry air.Paper will dilates after absorption, the size and acreage will increase, but will make mechanical strength lower.The paper will be shrinked after dehydration, the line size and acreage will become smaller and hard.So,we have to control paper moisture content and humidity of environment.

   In the whole printing process,papers will be taken out from the warehouse to cut,print and form, then moving from one place to anothers,so we have to consider the changes of temperature and humidity due to the transformation.
