Save PDF > Output now applies: colours convert to a destination profile
(destination, or preserveNumbers keeping the numbers of colours already in
its model; grey stays grey; images and freeform gradient images convert
too; printer's marks don't). Profile inclusion writes ICC-based colour
spaces (CMYK with the destination's or the document's profile, RGB as sRGB,
grey), and transparency in CMYK output blends in the CMYK profile's space.
The output intent profile is embedded as the catalog's /GTS_PDFX output
intent with its condition, identifier and registry, and Trapped goes in
the document information (PDF/A keeps its own). A shared patch module
edits written PDFs (Lab spot alternates use it too).
