his printing shop wants the ability to download just the header information from a pdf rather than the whole pdf file which may be up to 80 mbytes. From that header information they will have the ability to render individual pages rather than the whole document. For example, they could request page 264 and render that single page as a jpeg.

This sounds like "web optimized" PDFs, those contain a second object index at the start ("normal" PDFs have it at the end), so a *browser* can request selected pages from the *webserver* without loading the whole document.

It's meant as a web technology, and I never heard of anyone using it in a print workflow. But it's not impossible.

Tha has *nothing* to do with tagged PDF! "Tagged" is a technology to enable re-flowing text contents to e.g. small devices or extracting of content for alternative readers, e.g. screenreaders. PDFs for print should *not* be tagged in this way, for it can confuse a print workflow.

Printshops should adhere to printing standards like PDF/X-1a and PDF/X-3 - and these never need web optimization or tagging!

Excuse the ignorance, but does LuaTeX produce a PDF based on the PDF/X-1a and PDF/X-3 standards?

For ghostscript http://pages.cs.wisc.edu/~ghost/doc/svn/Ps2pdf.htm for pdftex http://tug.ctan.org/tex-archive/macros/latex/contrib/pdfx I'm not sure if luatex can produce these kind of pdf -- luigi
