• Developer: The type of developer used can also affect the sensitivity of the paper.
• Temperature: The temperature at which the paper is processed can also affect its sensitivity.
• Storage conditions: The paper should be stored in a cool, dark place to maintain its sensitivity.

4. What are the common problems that can occur during the testing of sensitized paper and how can they be resolved?

Some common problems that can occur during the testing of sensitized paper include:

• Fogging: This occurs when the paper is exposed to light before it is developed, resulting in a lack of contrast in the image.
• Uneven development: This can be caused by uneven exposure to light or uneven development of the paper.
• Stains: These can be caused by impurities in the water or developer.

These problems can be resolved by:

• Fogging: Use a safelight when handling the paper before it is developed.
• Uneven development: Agitate the paper during development to ensure even exposure to the developer.
• Stains: Use distilled water and clean developer to avoid impurities.

5. What are the safety precautions that should be taken when working with sensitized paper?

When working with sensitized paper, it is important to take the following safety precautions:

• Wear gloves: To protect your hands from chemicals.
