Hans,

I have the following sample:

    \setuppapersize[A5][A4]
    \setuplayout
      [marking=on]
    \setupexternalfigure[location=default]
    \setuppagenumbering[location=]
    \starttext
    \externalfigure[cow][width=\textwidth]
    \stoptext

These cut marks are lost after the first cut.

Would it be possible to have a marking=crossed such as the one proposed
in the attachment?

(BTW, I added them by hand with Inkscape, this is why they look awful.)

Many thanks for your help,

Pablo
