Case records
Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.
LINKED RECORD
Ink curing instruction
This ink requires exactly 26 minutes of drying after printing ends. Signing is permitted at the instant drying finishes.
This supplies the final required interval and its starting point.
CONTEXT NOTE
Edition list
The edition contains twelve signed prints on cream paper.
The edition size does not alter these recorded task durations.
PRIMARY RECORD
Press run
Preparation began at 14:08 and took 17 minutes. Printing began immediately afterward and took another 9 minutes.
Preparation and printing must finish in sequence before drying begins.
