Developers used with Visible Penetrants act as a blotter, pulling the penetrant from the flaw to the surface and increasing the size of indication to enhance visibility. Developers used with Fluorescent Penetrants add contrast making the indication more visible.

Many specifications today allow the use of any QPL approved developer with any QPL approved penetrant.

Non-aqueous, water-soluable, water-suspendable and dry developers are offered.
