<div>Hello Andreas.<br>
<br>
<div>You are wanting valid PDF/A output, right?</div>
</div>
<div><br>
</div>
<div>This format didn't exist when pdfTeX was designed and developed,</div>
<div>but that doesn't mean it cannot be achieved using appropriate macros.</div>
<div><br>
</div>
<div>l've been doing it for years, using the pdfx LaTeX package,</div>
<div>which relies on features in hyperref and some other packages.</div>
<div>(Indeed I'm now producing fully tagged PDF/UA and PDF/A-3a documents.)</div>
<div><br>
</div>
<div>The dependence on LaTeX itself should not be essential, but</div>
<div>it's certainly convenient to not have to reinvent the wheel for many things.</div>
<div><br>
</div>
<div>Study the coding within the pdfx package, to find how to overcome all the issues</div>
<div>that you mentioned in your posting.</div>
<div>See also videos of talks that I've given at TUG meetings.</div>
<div><br>
</div>
<div><br>
</div>
<div>Hope this helps.</div>
<div><br>

Well, not quite.<br>
<br>
$ weave weave.web; pdftex weave.tex<br>
<br>
produces 'weave.pdf' that gives tons of messages à la<br>
{Path|Text} object uses {Gray|RGB} based color space.<br>
on <a href="https://protect-au.mimecast.com/s/KneTC1WLjws5Z9jPsXkfRu?domain=freepdfonline.com">
https://freepdfonline.com/verifypdfa/</a><br>
<br>
Asking Auntie Google about this leads to this thread:<br>
<a href="https://protect-au.mimecast.com/s/Bh8eC2xMRkUOm9xBc9eNOB?domain=tex.stackexchange.com">https://tex.stackexchange.com/questions/61217/latex-color-and-icc-color-profile</a><br>
<br>
Downloading ICC profile 'sRGB2014.icc' from<br>
<a href="https://protect-au.mimecast.com/s/a38NC3QNl1S04E8yfvGl81?domain=color.org">http://www.color.org/srgbprofiles.xalter#v2</a><br>
and adding the relevant PDF code in '\ifpdftex' purges _all_ of these <br>
color warnings. What's left are these 'Preflight Results':<br>
<br>
Document Results<br>
XRef cannot be an object stream (not a PDF 1.4 compatible feature)<br>
Metadata key missing in root catalog<br>
MarkInfo dictionary is not present<br>
Structure Tree Root missing.<br>
<br>
Page 1 Results:<br>
Link Annotation's F key is missing<br>
Unicode info not available for font -- tons of these on every page.<br>
<br>
See the attached report file for details.<br>
<br>
Possible plans for C/WEB:<br>
(1) Refine the layout of the newly added code in 'pwebmac.tex'<br>
(2) Create similar code for XeTeX/dvipdfm<br>
(3) Copy this code in 'cwebmac.tex' and 'pdfctwimac.tex'.<br>
<br>
Current experiments are in branch <br>

Help would be appreciated. TIA!<br>
