Why Print Filtration Technology Must Address More Than Just Odours
In print shops, there’s often a distinct odour from inks, lacquers, adhesives, and solvents used during printing and finishing processes. While these smells can make the workplace uncomfortable, the impact of failing to control them extends far beyond just employee discomfort.
These odours come from fumes and tiny particles released during printing, which according to Safety Data Sheets, can contain harmful substances that pose health risks if not properly filtered out. Without effective fume extraction systems, workers may be exposed to airborne contaminants that could affect their long term health.
For print shop managers, investing in advanced filtration solutions like those from Donaldson BOFA is crucial for maintaining a healthy work environment. Beyond protecting staff, effective filtration also keeps the workspace clean, ensuring higher product quality and minimizing costly downtime caused by dust and particle build up.
Modern Print Inks and the New Demands on Fume Extraction
As the print industry faces growing concerns around emissions and workplace air quality, the supply chain has responded by introducing eco inks and eco solvent alternatives to traditional ink formulations. These newer inks are often less odorous, less flammable, and promoted as being more environmentally friendly.
However, while these alternatives may reduce noticeable odours, reviewing Safety Data Sheets remains essential. For instance, some eco UV inks often labelled as "odourless" can still release volatile organic compounds (VOCs) that require proper filtration. Beyond the solvents, pigments used in these inks may contain nanoscale particles that are also released into the air during printing processes.
So, despite advances in ink technology, the core issue for health and safety professionals isn’t whether fume extraction is needed it’s about selecting the right system. The most suitable solution will depend on the specific processes in use, the scale of the operation, and any additional technologies such as laser cutting or engraving, which are common in packaging production and can further contribute to airborne emissions.
As Darron Norrad, US Sales Manager for Donaldson BOFA, explains: “Whatever the scale, Donaldson BOFA’s filtration expertise can help match print processes to the right technological solution both to filter potentially harmful airborne contaminants from the workplace and to contribute to a clean operating environment.
“What’s critical for the print industry is that the extraction system meticulously balances air flow rates with a filtration architecture that delivers sufficient ‘dwell’ time capable of capturing particles and VOCs.”
Specialized Advanced Carbon Filters for the Print Industry
For the print sector, BOFA has developed advanced carbon filtration technology that combines a HEPA filter with a specialized chemical/gas filter in a single, compact unit. This integrated solution offers a cost effective and space efficient way to capture a wide range of hazardous emissions, including ozone from UV curing processes and solvents such as methyl ethyl ketone (MEK).
A standout in the range is the PrintPRO Universal, one of BOFA’s most widely used extraction systems for printing and print finishing applications. Designed for versatility, it can be tailored to different printer types and processes. Despite its compact and portable design, the PrintPRO Universal features high capacity gas filters and VOC carbon bed saturation monitoring, ensuring timely filter replacement and helping maintain a cleaner, low odour working environment.
