Pathfinder: Trap spreads the lighter colour into the darker as an overprinting strip where solid colours meet

Browse Source 
The Pathfinder panel menu's Trap… (object.pathfinder.trap) and Effect › Pathfinder › Trap… (pathfinder.trap, live on groups) share one geometry (vectorcraft_pathops::trap_band, vectorcraft_effects::trap): Thickness, Height/Width, Tint Reduction, Traps with Process Color and Reverse Traps, plus the effect's Precision and Remove Redundant Points. The panel's Trap is one undo step and groups the traps above the topmost selected object. Behaviour from https://helpx.adobe.com/illustrator/using/trapping.html and https://helpx.adobe.com/illustrator/using/pathfinder-panel-overview.html.
