I had a search too.

    4.2.3 Removing “Cut Marks”

    The standard macro package supplied with DWB, mm, prints small
    dashed lines or “cut marks” on any document printed with psroff.  To
    remove these marks, edit line 2923 of the file /usr/lib/macros/mmt.
    The line looks like this:

        .ti '--''--'

    Replace each dash (-) with a backslash followed by a space (\ ).
    The line should then appear as follows:

        .ti '\ \ ''\ \ '

(I think the replace-with-spaces idea might be so it's easy to find and
restore the change;  the technique is mentioned in the last link below.)

    X.\"   Some of these commands are specific to MM, you may have to change
    X.\"   the W, and trace down who fires the cut marks ")k" in MM.

An interesting 1986 thread on the problem in comp.text, with Henry
Spencer popping up.

So it seems as if it's historically normal to struggle with mm's crop
marks.

Cheers, Ralph.
