Daily QA checks for film processing include which combination?

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer: (A)

Daily QA checks for film processing focus on confirming that the developer equipment is operating under conditions that produce consistent image quality. The most reliable daily checks are verifying the processor temperature and ensuring the chemical activity of the developer and fixer is proper (levels and replenishment). Temperature directly sets development time and thus film density and contrast; if it’s off, every film will drift in density and contrast. Chemical activity tells you that the solutions are fresh enough and replenished properly so films actually develop and fix as expected; depleted or exhausted solutions lead to underdevelopment, poor contrast, or incomplete fixing. Because these two checks address the most immediate factors that cause daily, widespread processing variation, they provide a solid early warning system. Other checks, such as mechanical transport alignment or safelight integrity, are important too but are typically handled through periodic maintenance or separate QA steps rather than as daily checks.
