High humidity can cause powder particles to clump together, leading to uneven distribution and density issues when applying the powder onto the substrate.


  1. Climate Control: Maintaining a controlled environment with appropriate temperature and humidity levels is essential to minimize the impact on both film and powder. Using dehumidifiers or air conditioning can help stabilize the humidity in your printing area.

  2. Proper Storage: Store the film positives and powder in a controlled, dry environment to prevent moisture absorption. Sealable containers and desiccants can be used to protect these materials.

  3. Humidity Testing: Regularly test the humidity levels in the printing area to detect any fluctuations that may affect the printing process. Utilize hygrometers to monitor environmental conditions.

  4. Film and Powder Selection: Choose films and powders specifically designed to withstand varying humidity conditions. Some materials are more resilient and less prone to moisture-related issues.
