Create GWG 1v4 (PDF/X-1a)-compliant PDF files from your design application.
One of the key aspects of the 1v4 standard is that transparencies are composited (flattened). For the other aspects of the standard, see the GWG 1v4 specification.

file (Kodak_WebCmykHiRes_1v4.joboptions
) and, from the InDesign File menu, import it into InDesign: Adobe PDF Presets > Load. The Kodak preset is based on the GWG InDesign_CS2-and-up_WebCmykHiRes_1v4 preset. Kodak has edited it to change the compression from JPEG to ZIP and to prevent images from being downsampled. If you download other preset variants specific to your market segment (or presets for other applications) from the GWG site, make the same edits:
The GWG offers several presets for various market segment variants. Typically the differences are ink coverage or spot color restrictions. You can find all the GWG preset variants at http://www.gwg.org/application-settings. Sort by Vendor (Adobe) and Application (InDesign CS2 and up). Select a preset that is based on the 1v4 format.
For details on the various market segments, refer to the GWG Version Specification, and select the preset that meets your requirements. Remember to change the compression.
