Fountain Inspector
ChromaChecker Fountain Inspector — monitoring fountain solution pH, conductivity, and temperature, and correlating chemistry data with print quality outcomes.
Why Fountain Solution Chemistry Matters
Fountain solution chemistry — primarily pH, conductivity, and alcohol (or alcohol substitute) concentration — directly affects the water/ink balance on an offset press. A pH shift of 0.5 points or a conductivity drift outside the specification range can cause ink emulsification, toning, and inconsistent ink transfer. Fountain Inspector connects chemistry monitoring to print quality data, making the relationship visible and actionable.
Recommended Monitoring Intervals
Fountain solution chemistry can change throughout a production shift as paper dust, ink residue, and evaporation affect the solution. Recommended monitoring intervals:
- pH and conductivity: at the start of each shift and every 2–4 hours during production
- Temperature: continuous monitoring if using a chilled fountain system
- Alcohol concentration: once per shift or when solution is refreshed
- Full chemistry audit: when switching paper grade, ink system, or fountain solution brand
