Hello my question is for "On Export" (I'll use a event listener for this) indesign will automatically export only used Separations? I was on the regular Indesign forum and asked if indesign would accomplish this on its own and it will not. What i'm getting now is if my file has K, 110, 3145 instead of only having the file as a K, 110, 3145 its C,M,Y,K, 110, 3145 and nothing is on the CMY separations on the PDF.
No. There is no script for this, because InDesign is not able to do what you want.
Well crap. it was worth a shot. THank you
