In dry developer usage, the drying occurs immediately after removal of excess penetrant, before the inspection step. Which step follows the drying?

Explanation:
Drying prepares the surface for the development and inspection that follow. In dry-developer usage, the surface must be dry so the dry developer can interact with penetrant trapped in any flaws and reveal indications clearly under the chosen lighting. Moisture can suppress development or smear signals, leading to unreliable results, so you inspect after drying. Rinsing and penetrating application occur earlier in the process, and drying again isn’t part of the normal sequence.
