Hi,
I have found following example to set back cover of a booklet using
imposition on the wiki
\unprotect
\startvariables all
beforequadruple: beforequadruple
\stopvariables
\installpagebreakhandler \v!beforequadruple
{\ifdoublesided
\!!counta\realpageno
\!!countb\realpageno
\advance\!!counta 5
\divide\!!counta 4
\multiply\!!counta 4
\advance\!!countb 2
\advance\!!counta-\!!countb
\executepagebreakhandler\v!yes
\dorecurse\!!counta{\executepagebreakhandler\v!empty}%
\fi}
\protect
\setuppapersize[A5][A4]
\setuparranging[2UP,rotated,doublesided]
\setuppagenumbering[alternative=doublesided]
\starttext
\subject Front Cover
\dorecurse{10}{\input tufte \par}
\page[beforequadruple]
Imprint
\page
Back Cover
\stoptext
Unfortunately this does not work anymore nor in MKII or MKIV. Can please
someone give me some actual solution? Thanks.
