Managing colors, fonts, and flattening in PDF files


    You can set the following options in the Advanced section of the Adobe PDF Options dialog box:

    Embed ICC Profiles

    Creates a color-managed document. (See Embedding profiles in saved documents.)

    Subset embedded fonts when percent of characters used is less than

    Specifies when to embed the entire font (as opposed to just the characters used in the document) based on how many of the font's characters are used in the document. For instance, if a font contains 1,000 characters but the document only uses 10 of those characters, you may decide that embedding the font is not worth the extra file size.

    Overprint

    Specifies how to save overlapping colors that are set to overprint. You can choose to preserve the overprinting or discard the overprinting. If Compatibility (in the General area of the dialog box) is set to Acrobat 4 (PDF 1.3), you can also choose to simulate overprinting by flattening the artwork. (See About flattening transparent artwork.)

    Preset

    If Compatibility (in the General area of the dialog box) is set to Acrobat 4 (PDF 1.3) and the artwork contains transparency, you can specify a preset (or set of options) for flattening transparency. Alternately, click Custom to customize the flattener settings. (See Controlling flattening using transparency flattener presets.)

    Note: Acrobat 5 (PDF 1.4) and Acrobat 6 (PDF 1.5) automatically preserve transparency in artwork. As a result, the Preset and Custom options are not available for these levels of compatibility.
