There are three basics programs available for trapping.
- Illustration Software.
In vector-based drawing programs such as Adobe Illustrator you can create simple manual traps by applying outlines (overprinting strokes) to objects or use plug-ins that apply the appropriate trap.
- Page Layout Software.
High-end tools such as QuarkXPress, Adobe PageMaker, and Adobe InDesign have built-in trapping. Each program may have multiple ways in which trapping is applied.
- Dedicated Trapping Software.
Usually used by service bureaus and printers these programs are designed to do nothing but trapping. TrapWise and Trapper are two such programs.
Which program you use or how you set the trap depends on the number of overlapping objects, whether you are overlapping imported images, and the presence of gradient fills. Those are topics for future lessons in trapping.
