InDesign for QuarkXPress Users [Electronic resources] نسخه متنی

Setting Overprints

In QuarkXPress, overprint controls are in the Trapping panel of the Preferences dialog box and in the Trap Information palette. InDesign's overprinting controls are in the Attributes palette (see Figure 86-1), which is available from the Window menu. Here you can set whether to overprint the fill or the stroke of a selected object.

While people commonly use overprinting as a way to manually set the trap on an object, it is better used for intentional ink-mixing effects on press. Building manual traps with overprinting is a recipe for a headache; use InDesign's built-in trapping instead (see Chapter 97). Remember that overprinting only occurs when printing color separations. If you're just trying to create a cool effect, you may find using the Multiply blend mode much more flexible and effective than ink overprinting.

Previewing and Printing Overprints

While you can specify overprinting in XPress, there is no way to preview its effect (either on screen or on a color printer) before making color separations. In InDesign, you can: Select Overprint Preview from the View menu to see how overprinted inks will appear. You can work while this is turned on, but it does slow InDesign down a little bit. In addition, when printing composite color prints or making PDF files, you can turn on the Simulate Overprint option. The result is not suitable for final prepress work, but it excellent for inkjet printers and proofing.
