Choosing the Right CTP Plate for High-Humidity Climates in West Africa

West Africa’s humidity (often 70–90% RH) creates unique challenges for CTP plates. Standard plates can suffer from coating degradation, dot gain issues, and shortened run lengths if not properly specified.

Key Recommendations

• Thermal plates (Kodak Electra, Agfa Azura) generally outperform violet plates in high humidity due to better coating stability.
• Look for plates with enhanced anti-humidity coatings or those rated for tropical climates.
• Store plates in climate-controlled conditions (ideally 18–24°C, <60% RH) — we maintain this in both Accra and Lomé warehouses.
• Developer choice matters: Use the manufacturer-recommended developer and change it at the correct intervals.
