I was on the floor when an operator ran by me with a bucket. I followed him to the lithographic printing press where I watched him dump the bucket of chemicals into a chiller by hand. I asked why. He said he was having trouble setting his color. This was how they dealt with it. The top downtime in the factory was color setting time, the top quality defect was color variation, and the top waste was color setting waste. We had the Pareto charts. Everyone in ops knows the 80/20
