Re: [NTG-context] Overprinting
Here the results of my question:
I asked my print-service, if the pdf I generated with the
code (look at the end of this email), is ok.
The text in the second frame should be overprinted.
The answer of the printer:
in the preflight he can see the overprinting,
in the print-preview he can't.
He was astonished - because he never had the difference
between print-preview and preflight before.
He is using Adobe Acrobat 10.
Hope this information helps others to be cautious -
an maybe someone can tell what's to do.

probably not
your example works as expected here (tested with 08.11.2011 and 02.01.2012).
1 knockout (default)
2 overprinting
3 knockout (explicitly set)
as long as you use the second form, there shouldn't be a problem.

Was aber eben nur halb wahr ist: Der Bereich ist sehr wohl auf Überdrucken gestellt (kann man im Acrobat unter Ausgabevorschau-Vorschau-Farbwarnungen-Überdrucken_anzeigen sehen kann), gleichwohl wird schwarzer Text (und nur schwarzer! andere Farben werden korrekt separiert!), wenn man die schwarze Farbe in der Vorschau entfernt, regelrecht aus dem Hintergrundbild herausgeschnitten: http://www.sopos.org/olli/overprinting.jpg 403 :-( Wenn man's nicht jedesmal überprüft... scp erhält offensichtlich die Dateirechte, und die waren auf 0600 gesetzt :( Jetzt sollte es funktionieren.

Re: [NTG-context] overprinting
Hi Hans, hi all,
I use overprinting only for the texts (not global). Most times the
texts are stored in a \[h|v]box first, before they are added to the rest
(offsets, background, whatever). So thinks look like this (very simplified):
\setbox\Textbox\hbox{\startoverprint Some text.\stopoverprint}
Overprinting should be activated only inside of this box. Sadly mkiv
adds this attribute to most of the graphics with text. The first
graphics is always OK, but the following graphics are overprinted as a
whole.
I have compared the pdf of pdftex and luatex and the main difference is,
that luatex 'optimizes' the overprinted texts by *grouping* them.
Instead of two or more independent areas (one /GSoverprint ...
/GSknockout for every text), like in mkii,
% pdftex
%
/GSoverprint gs % text 1
BT
/Fm?? first overprinted text
...
/GSknockout gs
/GSoverprint gs % text 2
BT
/Fm?? second overprinted text
...
/GSknockout gs
%
I get
% luatex
%
/GSoverprint gs % text 1 and 2
BT
/Fm?? first overprinted text
...
/Fm?? second overprinted text
...
/GSknockout gs
%
This is right from the point of overprinting, but the texts are still
part of different graphics (rendering is done at different times). I
guess this somehow corrupts the grouping. The first graphic in such a
group is always OK, all following graphics are overprinted as a whole. I
have tested this with more than two graphics (resulting in two multiple
groups) and I get the same effect.
No minimal yet. Any thoughts?
Best wishes, Peter

no clue yet, but i'm working on it...
sure, as overprint is not aware of any content so you need to use
knockout then
mh, isn't \stopoverprint enabling knockout automatically?
or do i need a \ExtGState entry with knockout at the document level?
just started reading in the pdf reference manual...
it depends ... we have none: no entry at all, knockout: some nil
entry, overprint: special entry
the thing is that when we have globally overprint on, we need s local
knockout :
\startoverprint
... \bgroup ...
\startknockout
...
\stopknockout
... \egroup ...
\stopoverprint
is nicer than
\startoverprint
... \bgroup ...
\stopoverprint
...
\startoverprint
... \egroup ...
\stopoverprint

I see. A quick test shows, that this macro is not working with mkii (an
updated example is attached).
Sadly this macro also does not work in my graphics, if I simply exchange
\dostartoverprint with \startoverprint (regardless of the mark).

you need to enable it with \setupcolors[overprint=yes]
I tried that one before, but it enables kind of global overprinting in
mkii (all but \startoverprinting, including the mp graphic). In case of
mkiv this breaks the \startoverprinting macro (so no overprinting at
all). I attached a new example.
btw, your mkiv definitions do nothing (just toggle some flag) and the
\dodriverthing's are gone anyway
Ok, then I must find a new working overprinting macro for my texts.
