Discussion
Consider the following statements about maintaining a matching system.
1. The database degrades as dye lots and substrates change.
2. Periodic recalibration is required to maintain accuracy.
3. A database once built serves indefinitely without attention.
Answer: D
Correct answer: 1 and 2 only
Statements 1 and 2 go together: dye lots vary in strength, substrates change, and the database drifts out of agreement with reality unless it is refreshed. Statement 3 is the assumption behind most matching systems that stop working - a database is a record of how things behaved when it was built, not a permanent property of the colourants.
