Hi i have a problem and i don't know yet if it is related with embedded documents or the profile itself, but making a document 85x230 then making a new document and placing it inside one A4 document and exporting with PDF/X4 preset is producing almost a blank document (only have some lines on it). I can send you the files but privately if you want.
Created a file in the latest Designer, export (with bleed) to PDF, one of the images files is missing.
Recreated the file, exported to PDF, still missing one image - same image both times.
Fortunately, I have Publisher, recreated the file in Publisher and exported successfully to PDF with bleed.
