KM1 Output

[namelessentity]

We recently found a printer that's close by that has a KM1 and had a job run there. The output is really fantastic, but it smelled absolutely awful. Another employee and I had a ton of sinus issues and developed headaches from the smell. I even left it in our warehouse for 24 hours with a box fan on it and it still had an odor. Is this normal? It doesn't feel like a healthy thing to be exposed to.

It uses UV inks.

According to GoogleAI: "UV inks have a distinct, often pungent, odor. While they are considered environmentally friendly due to low volatile organic compounds (VOCs), they release chemicals during curing that smell, often described as a sharp, chemical odor similar to a powerful permanent marker. The smell can cause headaches, dizziness, and throat irritation, requiring proper ventilation. UV-curable inks and resins can have a distinct, lingering odor even after they are cured, typically smelling sweet, sharp, or like chemicals. This smell is caused by residual uncured components, fumes released during the curing process, or off-gassing from the printed material, which often requires 12–72 hours of ventilation to dissipate."

I get some post cards, menu's whatever all 4 color printing coated and in the hot summers my metal mailbox heats up and after 10 hours or so I collect the mail and when I open the door that smell of varnish, plastics, toner, and a touch of residual OZONE is indeed not causic
