A new patch is being pushed through the Updater right now. The new version is 10.0.2.419.
The SaveAsPDF CMYK option should be reasonably reliable now, but please run a preflight before submitting to a print provider.
From the Read Me file:
1. Following CMYK Workflow issues are fixed:
1.1 Custom spot colors were not preserved and were getting converted to process colors.
Further library process colors were being converted as spot colors.
1.2 Tints for spot colors were not visible in the generated PDF. Tints were not getting honored
for graphic objects and table cells for both spot and process colors.
1.3 Some fonts were getting replaced with Times New Roman font or were not rendered
properly. Most of these font issues and glyph rendering issues are resolved.
1.4 Kerning applied to the character style was not honored in the PDF.
1.5 Some page layouts were not honored in the PDF.
1.6 Provision for custom prolog file for PS was not there.
2. ‘SaveAsRTF’ command for a file containing unrendered graphics objects and structured window
open resulted in FrameMaker crash.
3. If the tagged view was ON, FrameMaker crashed on placing the insertion point between </
step> and </steps> and then pressing <ENTER> in task topic.
4. If the DITA cross-reference panel was open, the history panel was not populated on making
changes in a DITA topicref.
5. Right aligning a paragraph for which auto-number is set to ‘End of Paragraph’ earlier resulted in
disappearance of the auto-number.
6. ’Select All’ command was not selecting more than 100 Multiple Composite Objects in default
auto spell check mode.
7. View-only operation was not working for virtual documents with DFS SDK 6.5 SP3.
8. List sorting was case sensitive in FrameMaker 10. This is changed to case insensitive to match
the previous versions of FrameMaker.
9. F_ApiDeleteUndefinedAttribute and NextElementDFS are exposed in the Scripting interface.
