Bad PDF Export to x1a with indd placed in InDesign
- problem in InDesign CC2019 / macOS 10.14.3, 10.13.9
- no problem with previous InDesign versions (on 10.13 systems)
Sometimes i use InDesign document (page) placed into another InDesign document (because more work with some pages and reuse them in more documents). If these placed Indd documents contains RGB images with transparencies (like transparency in PSD files, or transparency effects applied to flat images in InDesign), these images are exported very bad, highly desaturated. But only when export to PDF X1a (required by our printer, i use profile "ISO Coated v2 300% (ECI)" in all indd). No problem when exporting to higher PDF versions like X-4 (even with Colour Conversion set to "Convert to Destination (Preserve Numbers)").
Now i solve this by exporting to PDF X-4 and use this PDF instead of direct indd placing to main document, but this is another step (was more practical use indd in indd, and when changes required, just "Edit original" and save, now are more steps needed like find original indd document in Finder and update PDF for update in main document).
I also tried export main document as X-4 and then flat this in Acrobat using Preflight, but have not found option to use "ISO Coated v2 300% (ECI)" profile and also it took long time (and crashed Acrobat).
Please, is it possible to fix InDesign 2019 for proper x1a PDF export (with placed indd documents with transparent rgb images)? It worked OK in older InDesign.
Please can you share the sample InDesign files that can help me reproduce the issue at firstname.lastname@example.org?
Please do add a small video illustrating the bug

thank you, i have some good experience editing the original file (PSD) placed in "named A file" and sale as CMYK instead RGB file. Most times this work well, so, you need to be more efficient and remove/convert manually from links box any RGB file.
But sometimes error persist even if you change file to CMYK, in that case, we solve exporting "A" file to PDFx1a and linking to PDF file instead INND file.
