How can we get Adobe to add a pdf export option as "printer spreads"?

Print designers need a way, when print shops request it,

I would question the competence of a printer who can‘t handle imposition. It’s similar to trapping, which is also a printer task. InDesign lets you set trapping rules, which may be applied when printing separations, but are not applied to the document pages or a PDF export.

I have a couple of PDF export scripts hanging around and I was testing the logic in a script and it works for a very basic case. But is failing for more robust scenarios. 

If your goal is a PDF that you can print as Printer Spreads then the advice is Acrobat and Print Booklet - as you’re looking to make a PDF anyway - so you can make a normal PDF and acrobat can print the booklet. 
I see no hangups here in workflows. 

However, if you give me the weekend I’ll keep working the script and finding other scripts to see how they work and see if I can get something together. 

There’s probably imposition scripts already out there - but if nothing is working - happy to put something together and see if it works.

 

The best advice I can give you is to give up the idea that imposition is part of a pagelayout application. It’s not. If you need in house booklets, export to PDF properly and use Acrobat’s booklet printing feature. Postscript is dead.

I know it’s not what you want to hear, but it is what it is. 

I guess it’s an alternative version of the feature request you already made yesterday… Did you get a chance to try the virtual PDF printer approach I suggested? 

Export to PDF then print from Acrobat which has the booklet option. 

That’s generally the best way.
