Which term describes the action of the developer that creates the maximum bleed-out of penetrant?

• A. Bleeding
• B. Blooming
• C. Blotting
• D. Bleaching

Answer: (C)

Bleeding (bleed-out) is the action where the developer draws penetrant out of a flaw to the surface, creating the strongest, most visible indication. Blotting, by contrast, is simply removing excess penetrant with absorbent material to control or reduce excess on the surface, not to create the bleed-out. Blooming refers to how the indication appears on the surface after development, which enhances visibility but isn’t the mechanism that drives bleed-out. Bleaching would fade or remove color, not produce the bleed-out signal. So the term that best describes the developer-driven maximum bleed-out is bleeding.
