Home Humidifiers 60Hz About Humidity Printing / Photographic Industries

Paper is hygroscopic, which means that it is very susceptible to changes in relative humidity (RH). For optimum printing and paper storage conditions the humidity should be kept between 50-60%RH.

Static build-up, web breaks and paper curl are all problems caused by dry air in the printing industry. By humidifying the atmosphere around printing presses, reel stand areas and paper stores, problems like these can be efficiently reduced. Changes in humidity will cause the physical dimensions of the paper to change which results in misregistration of colors in multi-pass jobs.

Benefits of right humidification:

  • Reduces deformation of paper
  • Reduce the accumulation of static, limiting paper sticking, misfeeding and not stacking properly
  • Ensures quality of the finished product.
