Electrostatics
Electrostatics causes problems when processing paper, films and packaging and always occurs when poorly conductive materials become charged due to rapid friction or sudden separation.
Benefits
Precise humidity control ensures consistently high print quality: electrostatic charges, dimensional changes and waste are minimised. Standardised process water and energy-efficient evaporative cooling reduce costs and increase productivity.
Reduce electrostatic
Additional air humidification reduces electrostatic charges on printing materials and machinery.
Prevent dimensional changes
Controlled humidity protects the dimensional stability of paper and cardboard.
Standardised print quality
Optimal humidity and standardised process water guarantee consistent quality without waste.
Printing facilities humidity control
Air humidification ensures print quality and efficiency
In the printing industry, constant humidity is a decisive factor for quality, efficiency and process reliability. Hygroscopic materials such as paper and cardboard are sensitive to climatic fluctuations. A relative humidity of 45-50% prevents dimensional changes such as warping and edge curling, which lead to registration errors, ghosting and creasing. In sheetfed offset printing in particular, stable flatness is essential for trouble-free sheet travel and precise printing results. In addition, controlled humidity reduces electrostatic charges that lead to double feeds, material jams, machine stops and unclean print images – especially in digital printing. Working conditions also improve: more dust binding and less strain on the mucous membranes. The right humidity increases productivity, reduces waste and ensures consistent quality.
Efficient cooling for the printing industry
In the printing industry, considerable heat loads are generated by waste heat from printing machines and finishing equipment. Compounded by high machine density, the room temperature can rise well above 26°C. This not only affects print quality, but also the concentration and health of employees. Adiabatic evaporative cooling offers an energy-efficient solution: The evaporation of water extracts heat from the air, which can lower the room temperature by up to 5°C – with minimal energy consumption. At the same time, the air humidity is increased, which reduces electrostatic charges, stabilises paper feed and improves print quality. The technology is particularly suitable for large or high printing halls and production rooms and can also supplement or replace existing air conditioning systems.
Double benefit: Standardised process water
In the printing industry, water quality is a critical factor for stable printing processes. Using air humidification with integrated water treatment provides a valuable additional benefit: the treated water can also be used as standardised process water for dampening solution production. The removal of hardness-forming substances such as calcium and magnesium as well as corrosive salts prevents the formation of deposits on ink rollers. A stable pH value between 4.8 and 5.5 ensures consistent printing conditions and prevents toning, emulsification and blank running. Standardised process water reduces operating costs and minimises cleaning effort. At the same time, machine service life is increased and print quality is ensured. Particularly efficient: water treatment is carried out centrally and hygienically – a real added value for printing companies.
Low humidity
Dry air below 40% relative humidity can lead to static charges due to friction. The material is no longer fed through the printing machine without deviations.
Optimal humidity
At 45–55% relative humidity, static charges can be easily dissipated due to increased conductivity. The material is fed through the printing machine without any problems.
Use cases
Prevent evaporative losses
Organic materials have an internal moisture content and will lose moisture to the atmosphere when exposed to air with a low humidity. Humidifiers are used to create an environment with perfect balance between the material’s internal moisture content and the air’s relative humidity.
Anti-static and ESD prevention
Low humidity increases static build-up because dry air is an insulator, making electrostatic discharge (ESD) more likely. Maintaining 40–60% relative humidity helps dissipate charges and significantly reduces ESD risk.

Polestar Group
A Condair ML Solo high pressure humidification system has been installed in the litho platemaking area at Polestar print company's award-winning plant in Sheffield. Designed to suppress and disperse electrostatic charges when protective film is removed from the plates, Condair's low-energy humidifier maintains a relative humidity of 45% in the area. The project was carried out by Cambridgeshire-based HVAC and process engineering specialist, Arcade.Polestar Sheffield produces 2.5 million high-quality catalogues, magazines, brochures and newspaper supplements every day. Part of Polestar Group, the company produces many well-known titles including Cosmopolitan, Radio Times, Woman's Own, Country Life and many Sunday newspaper supplements.With a strong focus on printing excellence and productivity at Polestar, the new humidifier installation provides an effective solution to the problem of electrostatic charge generation when protective paper is removed from the litho plates. By reducing and dissipating the electrostatic charge, the paper and plates are easier to handle, it prevents the attraction of dust and reduces the risk of spark generation. The Condair ML humidifier delivers ultrafine sprays directly into the air, which rapidly evaporate to maintain a relative humidity of 45%RH, the level required to counter the effects of static electricity.

Quotes from our customers
Jeremy Rawley
Safety and Facilities ManagerWe already knew Condair, as we have a couple of their units in other print rooms. The quality of their equipment is right up there. Paper is susceptible to changes in environmental conditions so humidity is really important. Their service is second to none as well. We work to tough deadlines and one of the key things for us is that Condair could supply the equipment quickly within the required timescale.
Having a local service engineer on call to maintain them in tip-top condition is important for us too.
