1.How fast can we run the machine?
-Just like the car, new machine has a run-in period, we suggest that you run 60% percent of its highest speed for at least 2 weeks, the you can run it faster, say 80% of its highest speed. The smaller the cup is, the faster we run the machine. According to our experience, for 500ml cup, we run the machine at the speed of 10000-12000 per hour; for 700ml cup, the speed is about 8000-10000 per hour.
2.How long should we replace the UV lamp?
-The service life of UV lamp is about 400 hours for the 6 color cup bowl offset printing machine. Theoretically you need to replace the UV lamp every 20 days assuming that you run the machine 20 hours per day. But in practice, you should replace the lamp when the light gets dark and the UV curing weakens.
