Pre-Press Checks for CTP-S Thermal Plates Inspection and fountain solution control
Inspect the plate under strong, even lighting. Look for:
⚠️ Recurring scratch pattern? If scratches appear in the same location on every plate, check the CTP unit and plate-loading equipment for sharp edges or worn parts.
The dampening solution is the first line of defence for the non-image area. Ensure:
| Parameter | Target Range |
|---|---|
| pH | 4.8 – 5.5 (acid range) |
| Isopropanol Concentration | 8–12% (if used) |
| Conductivity | 800–1,500 μs/cm |
💡 Remember: A fouled fountain solution will cause toning on any plate. Don't blame the plate for a chemistry problem.
Two minutes of pre-press inspection saves hours of press downtime. Visual inspection catches mechanical damage before it reaches the cylinder. Fountain solution control prevents chemistry-related toning that no plate can overcome.
