How do I export separations for Lithographic printing?

[AMORE]

Hello,

I work at printers where we use a two-colour litho machine for printing larger jobs. I use InDesign print options to export to a postscript file with separations but recently have come across an error after recent updates. I have tried installing an older version to no avail. I should add that the problem only occurs when trying to export with trapping.

The error is: "Export Error: The Adobe Print Engine has failed to output your data due to an unknown problem."

I came across another thread where someone had the same issue but their troubleshooting did not help in my case. 

This raises the question: what is the most common way people export files for printing in this method? I have always used this method as it is what I was taught when I started working here, but it seems out-dated.

Hm. Maybe a Windows update broke the feature?

Pure speculation from my side.

Definitely a possibility. I've been meaning to have a look into that.
