How to solve the problem of strong odors from UV printing ink?

First, choose high-quality, food-grade, and environmentally friendly UV ink. Avoid cheap, off-brand solvent-based UV inks, which not only have a strong smell but are also pungent and irritating.

Second, improve exhaust and ventilation. Install an exhaust fan above the machine to vent the odors directly outdoors.

Third, keep the workshop well-ventilated. Do not print in an enclosed space.

Fourth, use activated carbon or a photoelectric (UV/Ozone) air purifier.

I strongly agree with the first point. Buying original ink from the manufacturer isn’t just about safety—it’s also about print quality and equipment protection. The machine’s built‑in color and density curves are specifically calibrated for original inks, so they deliver the best possible output. Using off‑brand inks can easily throw off that calibration, leading to poor colour reproduction, inconsistent curing, and even clogged nozzles or damaged printheads over time. It’s simply not worth the risk.

Your points are well-taken, and it's crucial to use high-quality UV ink for both safety and print performance. For the ventilation step, ensure the exhaust system is properly sized to handle the volume of fumes, as under-ventilation can lead to odor recirculation. Have you considered the placement and design of your exhaust system to optimize air flow and odor removal?
