(also see wolfgangs mail)

I tried this in acrobat:

\defineviewerlayer[visibleandprint]      [printable=yes,state=start]
\defineviewerlayer[visibleandnotprint]   [printable=no, state=start]
\defineviewerlayer[notvisibleandprint]   [printable=yes,state=stop]
\defineviewerlayer[notvisibleandnotprint][printable=no, state=stop]

\setupinteraction[state=start]

\starttext

\startviewerlayer[visibleandprint]       visible and print 
\stopviewerlayer \blank
\startviewerlayer[visibleandnotprint]    visible and not print 
\stopviewerlayer \blank
\startviewerlayer[notvisibleandprint]    not visible and print 
\stopviewerlayer \blank
\startviewerlayer[notvisibleandnotprint] not visible and not print 
\stopviewerlayer \blank

\stoptext

and found out that we need an extra piece of info for acrobat to be 
happy. I'll upload a beta with that addition.

I wonder if other viewers handle layers well.
