Paper is a natural material and very susceptible to changes in relative humidity. If the atmosphere around printing presses and paper storage areas becomes dry, the paper's exposed edges will suffer dimensional change, causing it to curl.
Tight edges on reels can lead to web breaks and increase machine downtime.
A low humidity also increases static build-up, which can cause paper to stick together and not feed or stack correctly.
A constant, optimum air humidity is a key factor in attaining a high quality of print and ensuring smooth production processes. During the winter months, in particular, the room air humidity in printing plants often falls to critical levels: paper distortion, static, impaired machine running, production stoppages and resultant avoidable additional costs are often the negative consequences.
