Here's the example. It's basically the code from DIN Lang Folder in the Wiki plus a setupbackgrounds command. It works with `page` but fails to work with `paper`: %% This is a template for a Din lang Folder. %% The folded page of such a flyer is shorter (97mm) than the other pages (100mm) %% This measure shows how much shorter the folded page is. \definemeasure [shortfold] [3mm] %% The bleed measure is necessary if you have colored page backgrounds %% or images in the bleed. %% Different print shops need different bleeds. \definemeasure [bleed] [1mm] %% This is the pagesize of the final PDF. %% The bleed size is added two times to width and height. \definepapersize [A4-flyer] [width=\dimexpr297mm+2\measured{bleed}\relax, height=\dimexpr210mm+2\measured{bleed}\relax] %% The size of a normal page. \definepapersize [flyer-page] [width=100mm, height=210mm] %% The size of the folded page. \definepapersize [flyer-page-small] [width=\dimexpr100mm-\measure{shortfold}\relax, height=210mm] %% Imposition: With the following two commands we arrange the six pages %% on the final PDF print sheet. %% The flyerpages are imposed on the printed sheet. \setuppapersize [flyer-page] [A4-flyer] %% The pages are arranged as a tryptichon. \setuparranging [TRYPTICHON] %% Because of the shorter folded page and the bleed the pages has %% to be shifted horizontally on the printed sheet. %% The values are calculated here. \definepageshift [flyer] [horizontal] [\dimexpr\measure{bleed}-\measured{shortfold}\relax, \measure{bleed}, \measure{bleed}, \dimexpr2\measured{shortfold}+\measured{bleed}\relax, \measure{bleed}, \dimexpr\measure{bleed}-\measured{shortfold}\relax ] %% The vertical pageshift is simple. \definepageshift [flyer] [vertical] [\measure{bleed}] \setuppageshift [paper] [flyer] %% We define some measures to construct the page layout. \definemeasure [small] [3mm] \definemeasure [big] [\measure{small}*2] %% Each page has a slightly different page layout. %% The named layouts (1. bracket) inherit values from other layouts %% which are assigned in the second bracket. \definelayout [first] [page] [page=flyer-page, topspace=2\measured{big}, backspace=2\measured{small}, width=\dimexpr\paperwidth-4\measured{small}\relax, height=\dimexpr\paperheight-4\measured{big}\relax] \definelayout [second] [first] [topspace=2\measured{big}, backspace=2\measured{small}, width=\dimexpr\paperwidth-2\measured{big}\relax] \definelayout [thirdandfourth] [second] [backspace=\measure{big}, width=\dimexpr\paperwidth-2\measured{big}\relax] \definelayout [fifthandsixth] [first] [backspace=\measure{big}, width=\dimexpr\paperwidth-2\measured{big}\relax] %% We assign the layouts to the pages. \definelayout [1] [first] \definelayout [2] [second] \definelayout [3] [thirdandfourth] \definelayout [4] [thirdandfourth] \definelayout [5] [fifthandsixth] \definelayout [6] [fifthandsixth] %% Some setups \setupmakeup [doublesided=no] \setuptolerance [verytolerant] %% We want to see page and layout borders. %% COMMENT THIS OUT BEFORE YOU PRINT! \showframe \setupbackgrounds[paper][background=color,backgroundcolor=blue] \starttext \starttitle[title={First page}] \input lorem \stoptitle \starttitle[title={Second page}] \input lorem \stoptitle \starttitle[title={Third page}] \input lorem \stoptitle \starttitle[title={Fourth page}] \setuppapersize [flyer-page-small] [A4-flyer] \input lorem \stoptitle \starttitle[title={Fifth page}] \input lorem \stoptitle \starttitle[title={Sixth page}] \setuppapersize [flyer-page] [A4-flyer] \input lorem \stoptitle \stoptext
