Printing Rooms

Prints have a delicate relationship with moisture. Low humidity means paper curling, misfeeds, and light or faded prints. High humidity means paper shrinkage and dimensional changes. In the printing room, the goldilocks zone rests around 40-50% Relative Humidity (RH). But if high quality prints and little downtime are to be consistent, this is everything humidity must do.

The Humidification Challenge

How Insufficiency Humidity Ruins Products:

If humidity levels in the room drop below 35% RH, static levels will climb. As low-humidity conditions prevent charges on the papers from dissipating properly, charges accumulate on the paper and other surfaces.

These charges cause sheets to repel each other, ultimately triggering refeeds and reprints.

How insufficiency Humidity Harms Productivity

Low-humidity conditions also stress the printing machine. From static to web breaks and paper curls, every issue caused by low-humidity weakens printing press performance and shortens its lifespan.

Over time, more misprints, more repairs, and more downtime slows operations down.

Not All Humidifiers Offer efficient Solutions

Even if traditional humidifiers mitigate these inefficiencies, the attractions between the water droplets that typical humidifiers generate make it too easy for humidity levels to fall outside the goldilocks zone.

Too few droplets, uneven saturation allows static to build. Too many droplets, puddles and condensation form and damage materials.

The Self-Evaporative Solution

Ensuring Smooth Processes

By reversing the charges of water molecules, self-evaporative humidification causes water droplets – not paper – to repel from each other.

This eliminates static in the air and reduces paper misalignments and refeeds, all without wetting the paper, the printer, or any other surface.

Energy Efficiency:

Additionally, self-evaporative humidification is the most energy efficient method of generating the perfect amount of moisture.

Traditional humidifiers work by creating heat, steam, or pressure – processes that consume a lot of energy. Self-evaporation uses a natural, mechanical process called decorrelation to generate efficient, consistent humidity.

Empowering Print Rooms:

When printing shops leverage self-evaporative humidification, moisture reliably eliminates static, evenly saturates the room, and never wets or fluctuates.

By ridding printing rooms of paper-curl, web-breaks, mis-registers, and more wear and tear, self-evaporative technology boosts printing productivity and reduces downtime and expenses.
