One of the first works I had when I started living on my own was this tiny factory on a major industrial road in my city. It was so small because it wasn’t a factory–it was honestly a major printing press. The supplier only had 50 employees total, but they printed napkins for the Super Bowl every year. They worked with major candy companies in Canada & even printed cups & wine glasses for pharmaceutical charity events. The way they were able to do so little with so few workers is because they had these incredible machines which you needed years of experience to operate. I was baffled when I first saw them–I thought laptops did all of the several color or more process printing for napkins. They said no, no digital printer could handle the volume or the paper ply without jamming, however just 1 of these printing presses would take up my entire three kitchen apartment. The key to running them was temperature control. As long as the industrial Heating & A/C plan kept the severalcolor process floor at 60 degrees, the machines would run perfectly. Any warmer than that, the ink would beginning to run & ruin the design. If the climate control was colder by just a few degrees, the ink wouldn’t coat the stamp & the entire equipment could jam. I was baffled that such an enormous equipment all came down to the right temperature control setting to whether it would run perfectly, or ruin a million dollar work. My boss laughed & said that’s why they always kept on top of their proper Heating & A/C service–to stop the central cooling system from ever tearing down.
