Seasonal changes can affect the water temperature and ink behavior of an offset press. Before autumn production, clean the water tank, inspect hoses and seals, and verify circulation, conductivity and pH according to the press and fountain-solution specifications. Keep the pressroom temperature and humidity stable, and allow the tank and ink duct to reach a consistent operating condition before fine adjustment. Watch for condensation on cold surfaces, but do not change water or ink settings blindly. Record the measured values and adjust one variable at a time so that print quality remains traceable.
Practical steps
- Clean the tank and filters, then check circulation and leaks.
- Measure temperature, conductivity and pH with calibrated instruments.
- Insulate or manage cold surfaces where condensation is observed.
- Record seasonal settings and confirm color, registration and drying on a test sheet.
