1.5.5 Why can I not select X1a as a PDF Export option?

I'm using version 1.5.5 

I need to have my file be PDF/X-1 complaint.

But in the PDF Export all the X options are faded out and not usable.

Can someone tell me why and/or what to do?


Hi John, are all of your images CMYK and above 300dpi?  This is just a first guess on my part without having the file and associated pics to look at, I could be wrong...




no, pdf versions are not just magic numbers.

hi yackel

each version has its specific characteristics and might have some specific constraints.

for the X versions, i'm pretty sure that you need to use the color management.

you can see this as a task to check (just activate it) or as a step that makes sure that the pdf has the quality you're aiming to.


(the color management gets activated in the document setup...)

Thank you both!

Hitting the 'Toggle Color Management System' made the option come up.


Thank you, guys, for asking and answering this question! I was having the same problem and couldn't figure out what had gone wrong.
