That's a good point. Here's another thing to look out for in InDesign when
converting.
1) Go to "Assign Profiles"
2) Select Perceptual Intent for images, and Relative for Line-Art, and
assign your working spaces
3) Draw a 100% Cyan square on the page (for example)
4) Draw some black text with a drop shadow somewhere in the middle
5) Now export that as a PDF 1.3 file using the High Resolution flattener and
convert to some other CMYK profile
Result) The cyan background behind the text is a different color to the rest
of the cyan background. During flattening, the drop shadow behind the text
is turned into an image and is converted using the perceptual intent, where
as the rest of the cyan box remains line art and is converted using
relative. You would expect the image created during flattening to be
converted using relative because the user created it as line art.
