Our shop has 3 printers (Mutoh VJ-1604, ColorSpan UVR72, Roland SC-540) which are often running simutaneously. The area is fairly well ventilated with windows that open and 2 doors which see a lot of traffic (One leads out to our wearhouse, the other to outside.) but no exaust fans other than the building's own HVAC system. When people who aren't regularly in the shop come in they often say something like "Man, how can you stand it in here?" The smell of ink is that strong. I don't smell anything. I'm sure this isn't good but I've done a bit of research and all the info I can gather says that solvent and UV curable inks are "safe". I've worked here almost 10 years. Should I be worried?
