Precision HVAC for Printing & Paper Industries

Maintain optimal temperature and humidity for flawless prints and efficient production.

In order to ensure an efficient process and excellent and consistent quality of the printed product, the temperature and humidity in places designed for the storage and printing of paper and cardboard needs to be controlled appropriately.

Consequences of Uncontrolled Humidity in Printing

Paper Jam

Due to static electricity, sheets of paper tend to adhere to one another, creating difficulties in feeding the printing machinery.

Dimensional Variations & Loss of Flatness

This causes misfit in the machinery and subsequent stages, resulting in stoppages or defects.

Misregister

Dimensional variations may cause misregister, producing blurry or misaligned images.

Ink Mist

High static electricity can lead to ink droplets deviating from their required path, blocking nozzles and causing halos in prints.

What are the effects on paper?

The hygroscopic nature of paper

Paper is a hygroscopic material that tends to reach a condition of equilibrium with the surrounding environment in terms of moisture content. Swings in ambient temperature and humidity with respect to equilibrium values can therefore cause dimensional variations and loss of substrate flatness.

Corrugation

If paper is exposed to an environment with excessive moisture, the outer parts of the sheets quickly absorb moisture and increase in length, causing corrugation (more frequently in summer, in places without air-conditioning).

Curling

If the air is too dry in the storage environment, the paper releases part of its moisture from the edges to the centre. The result is a sheet with the edges curled upwards.

Relative humidity and static electricity

If the air is too dry, unwanted static electricity may also form, another cause of rejects due to improper paper feed and consequent inaccuracies in the printing process. Humidity also affects runnability, i.e., the workability of the substrate, as well as its ink absorption properties—how well and how quickly it absorbs the ink or attracts the toner.

Using a humidification system that keeps ambient conditions at 55-60% RH (offset printing) or 50-55% RH (digital printing) thus brings significant savings in terms of time, production, and operating costs.
