Dry air in the printing industry can cause paper curl, web breaks and static build up; issues that are ever more regular in the winter months. When spooling the paper, printing presses may generate electrostatic charges, this can then mean that the pages become hard to separate.
The optimum humidity for printing and paper storage conditions should be between 50-60% RH.
By using humidity control to stabilise the conditions, dimensional stability of paper and other hygroscopic materials in the print room is improved and therefore machine breaks and downtime is significantly reduced. Machinery will also be able to work at higher speeds.
Not to be forgotten is the positive effect of appropriate and stable humidity levels on the health and wellbeing of employees – thereby reducing sickness and absenteeism. All of these clearly have a significant effect on productivity.
Every print or press room is different: size, height of ceilings, number of windows, ventilation, amount of machinery and people, and – of course- budget. All these factors will influence the levels of relative humidity and therefore a system needs to be designed to suit each specific building. At Humidity Solutions, we listen to our customers’ requirements, carefully assess the conditions, and choose from a range of equipment to design the ideal solution for each project.
For further detailed information, we have produced our own guide – Humidity and Temperature Control for Print.
