Trapping attempts to compensate for the misregistration of ink by expanding lighter areas of color to slightly overlap darker ones. QuarkXPress lets you create traps automatically by specifying default application and document-specific trapping preferences. You can further customize your traps by specifying trapping values for individual colors in relation to other colors, and you can customize trapping for specific items in a layout.
