Transparency features in graphics applications allow users to create elements with drop shadows, overlays, blends and feathering. Because transparency effects can be complex, be sure to consult us for best results. But the following notes should point you in the right direction for getting your artwork ready for print.

TRANSPARENCY IN ADOBE ILLUSTRATOR

• Select [File: Document Color Mode] and choose [CMYK Color].

• Set the [Effect: Document Raster Effects Settings] Color Model to [CMYK] and the Resolution to [High (300 ppi)]. Any effects that require rasterization will use the value specified here.
• Use the Transparency palette and [Effect] stylize menu to control transparency effects. Note that [Filters] can produce unpredictable results.
• The [File: Document Setup: Transparency: Preset] should also be set to [High Resolution].
• The Flattener Preview palette [Window: Flattener Preview] can identify areas that have transparency applied or are effected by other objects.
• Be sure to enable [View: Overprint Preview] for the most accurate display of what the fi nal design will look like.

TRANSPARENCY IN INDESIGN

• Select the [Edit: Transparency Blend Space] to [Document CMYK].
• Use the Transparency palette to control transparency effects.
• The Flattener Preview palette [Window: Output: Flattener Preview] can identify areas that have transparency applied or are effected by other objects.
• Be sure to enable [View: Overprint Preview] for the most accurate display of what the fi nal design will look like.

PRINTING WITH TRANSPARENCY

• In the printing or exporting windows always select [High Resolution] for the Transparency Flattener.
• Printers often define flattening settings or flatten artwork themselves. Consult your us to determine if your work should be submitted flattened or with live transparency. Note that transparency effects will always flatten when printing to PostScript or EPS, or if they are exported using the Acrobat 4 (PDF 1.3) format. Transparency effects will remain “live” only if exported using the Acrobat PDF 1.4, 1.5 or 1.6 formats.

CAUTIONS

• Use spot colors in transparency effects with discretion. When spot colors contact CMYK objects with transparency, the best practice is to make sure they are on the top of the stacking order.
• Avoid transparency designs that contain both RGB and CMYK content.
• QuarkXPress 6.5 does not have built-in support for transparency.
