Adobe InDesign - Manual (Page 658)

If this happens, do either of the following:
Move the text to the top of the stacking order. Use the Selection tool to select the text frame, and then choose Object > Arrange > Bring to
Front.
Expand all text to outlines for a consistent effect throughout the document. To expand all text to outlines, select Convert All Text To Outlines
in the Transparency Flattener Preset Options dialog box. Selecting this option may affect processing speed.
Image replacement
The flattener requires high-resolution data to accurately process a document with transparency. However, in an OPI proxy workflow, placeholder or
proxy images are used, for later replacement with high-resolution versions by an OPI server. If the flattener doesn’t have access to the high-
resolution data, then no OPI comments are produced and only the low-resolution proxy images are output, resulting in low-resolution images at
final output.
If you work in an OPI workflow, consider using InDesign to substitute images before saving the document as PostScript. To do this, you must
specify settings both when you place the EPS graphic and when you output it. When you place the EPS graphic, select Read Embedded OPI
Image Links in the EPS Import Options dialog box. When you output, select OPI Image Replacement in the Advanced area of either the Print or
Export EPS dialog box.
Color conversions
If a transparent object overlaps a spot color object, undesirable results may occur when you export to EPS format, and then convert spot colors to
process colors upon printing or create color separations in an application other than InDesign.
To prevent problems in these cases, use the Ink Manager to convert spot colors to process color equivalents as necessary prior to exporting from
InDesign. Another way to prevent problems is to make sure that your spot inks are consistent in both the original application (for example, Adobe
Illustrator) and InDesign. This may mean that you’ll need to open an Illustrator document, convert a spot color to process color, export it again to
EPS, and then place the EPS file in your InDesign layout.
Adobe PDF files
Exporting to Acrobat 4.0 (Adobe PDF 1.3) always flattens a document with transparency, which may affect the appearance of its transparent
objects. Nontransparent content is not flattened unless Simulate Overprint is selected in the Output area of the Export Adobe PDF dialog box.
Therefore, when you export an InDesign document with transparency to Adobe PDF, do any of the following:
Whenever possible, choose Acrobat 5.0 (Adobe PDF 1.4), Acrobat 6.0 (Adobe PDF 1.5), or Acrobat 7.0 (Adobe PDF 1.6) compatibility in the
Export Adobe PDF dialog box to preserve transparency in a live and fully editable form. Make sure that your service provider can handle
Acrobat 5.0, Acrobat 6.0, or Acrobat 7.0 files.
If you must use Acrobat 4.0 compatibility, your document contains spot colors, and you want to create a PDF file for on-screen viewing (such
as a client review), you may want to select the Simulate Overprint option in the Output area of the Export Adobe PDF dialog box. This option
properly simulates the spot and transparent areas; recipients of the PDF file won’t have to select Overprint Preview in Acrobat to see how the
document will look when printed. However, the Simulate Overprint option converts all spot colors to process color equivalents in the resulting
PDF file, so be sure to deselect this option when you create the PDF for final production.
Consider using the predefined [Press Quality] Adobe PDF preset. This preset contains flattener settings appropriate for complex documents
intended for high-resolution output.
Trapping
Flattening may convert vectors to rasterized areas. Traps applied to artwork in Adobe Illustrator using strokes and placed in InDesign will be
preserved. Traps applied to vector artwork drawn in InDesign and then rasterized may not be preserved.
To keep as many objects vector as possible, select the [High Resolution] transparency flattener preset in the Advanced area of the Print or Export
Adobe PDF dialog box.
