Especially this one, it depends on a lot of files. I wanted to extract ideas 
how to build the XMP, how to include the ICC but I gave up.

XMP is done via a template file; e.g.  pdfx.xmp  or  pdfa.xmp .
There are many places where information can be supplied, via macros
such as  \xmp@Subject  and  \xmp@Author .
Much of the  pdfx  package is about supplying values for these, in UTF8 
encoding.


I know, writing XMP is easy, I do not know how to include it. I do not like to 
use hyperref for a document that will only be pronted and never will be online.

Using pdfTeX it is done like this in  pdfx.sty :

   \def\pdfx@numcoords{/N 4}% for CMYK colors
   \immediate\pdfobj stream attr{\pdfx@numcoords} file %
 {\pdfx@CMYKcolorprofiledir\pdfx@cmyk@profile}%
   \edef\OBJ@CMYK{\the\pdflastobj\space 0 R}%

Then that object reference in \OBJ@CMYK  is required for the  OutputIntent .
viz.

  \def\pdfx@outintent@dict{%
/Type/OutputIntent
/S/GTS_PDFX^^J
/OutputCondition (\pdfx@cmyk@intent)^^J
/OutputConditionIdentifier (\pdfx@cmyk@identifier)^^J
/Info(\pdfx@cmyk@intent)^^J
/RegistryName(\pdfx@cmyk@registry)
/DestOutputProfile \OBJ@CMYK
   }%

which is linked to the PDF Catalog via:

 \immediate\pdfobj{<<\pdfx@outintent@dict>>}%
  \edef\pdfx@outintents{[\the\pdflastobj\space 0 R]}%
 \def\pdfx@outcatalog@dict{%
  /ViewerPreferences <>
  /OutputIntents \pdfx@outintents % needs appropriate expansion
 }%
 \pdfcatalog{\pdfx@outcatalog@dict}%


Of course you need to supply all the information for the macros:
  \pdfx@cmyk@….
and  \pdfx@CMYKcolorprofiledir  (possibly empty).


Using XeTeX there is similar coding using  \special s,
including symbolic names for object references.
e.g.

\def\OBJ@CMYK{@colorprofile}%
\special{pdf:fstream @colorprofile %
  (\pdfx@CMYKcolorprofiledir\pdfx@cmyk@profile) <<\pdfx@numcoords >>}
   \def\pdfx@outintents{ @outintentsarray }%
   \def\pdfx@outintentref{ @outintent@dict }%
   \immediate\special{pdf:obj \pdfx@outintentref << \pdfx@outintent@dict >>}
   \immediate\special{pdf:obj \pdfx@outintents [ ]}%
   \immediate\special{pdf:put \pdfx@outintents \pdfx@outintent@dict}%

with \pdfcatalog defined appropriately:

 \def\pdfx@catalog@xetex#1{\special{pdf:put @catalog <<#1>>}}


You should be able to put all the pieces together now.

Cheers,

Ross

Ah, yes, sorry about that Bruno.  I thought I had stripped out all external 
dependencies, but clearly I had not.  The "cropmarks.tex" is my own, written 
over 20 years ago for Kaveh and/or Dominik -- somewhere on CTAN, but I no 
longer remember where.  Anyhow, I have (sort of) tracked down the issue -- two 
things are affecting the displacements (both vertical /and/ horizontal, as it 
turned out) :

1) The PDF/X-1A specials;
2) The \usepackage {color} within an Eplain \beginpackages ... \endpackages 
sequence.

More research needed on my part to identify the exact cause in both cases.

In fact, run against (e.g., the HTML 5 speed tester), I get quite good download 
speed normally, but TeX Live installation always takes forever.  I know from 
past experience that Rsynch is much faster, but that no longer works for TeX 
Live 2016 (reported a couple of days ago), so I have little option but to sit 
it out ...

Repost of Rsynch problem, in case anyone can shed light on it :

It is strange, you should complain for poor connection. My ADSL speed
is nominally 8 Mbps. Since the line is overloaded, the real speed is
usually 6 Mbps. Installation of scheme full from the neares mirror
takes about one hour. You wrote your speed is 2.7 Mbps, so it should
complete withint two or three hours. The problem may be cause by loss
of too many packets due to some noise. So you probably pay for very
low quality and the provider should fix it. Many companies provide
free service for measurement the real speed, you just connect to a web
page of such a company and it measures the speed of download and
upload and stability. If it is too different from what you pay, you
should complain.

Sadly I exaggerated; 10 hours later, still at 1983/2981 :-(
