Hello: I'm composing an A5 booklet printed on an A4 paper using the 2UP imposition schema. I believe, in such case, margins should be controlled using 'backspace' and 'cutspace' options of the \setuplayout command, but I'm afraid I don't quite understand how to use those properl. I want to make the 'external' margin (right on odd pages and left on even pages) as small as possible, and the 'internal' margin larger, so that I can hole punch the booklet. I believe, in such case, margins should be controlled using 'backspace' and 'cutspace' options of the \setuplayout command, but I'm afraid I don't quite understand how to use those properly. Here's a minimal example: \setuppapersize[A5][A4] \setuparranging[2UP,rotated] \setuplayout [topspace=13pt, backspace=30pt, cutspace=-20pt, width=fit, height=fit, header=0pt, footer=0pt] \setuppagenumbering[state=stop] \setupbodyfont[small] \starttext \dorecurse{20}{\input tufte \vskip 1em} \stoptext I wonder how I could reduce the left margin and increase the left one on the even pages. Any pointers, please? Thank you so much in advance. Ángel
