I want to set up a book 5.5 x 8.5 with .5in margins left and right. During the development process I want to be able to print it on US standard 8.5 x 11 sheet of paper. Here is my current prologue (I have tried several): \setupoutput[pdftex] \definepapersize[bok][width=5.5in,height=8.5in] \setuppapersize[bok][letter] \setuplayout[marginwidth=.5in,location=middle] \showframe When the resultant pdf is printed via Acrobat Reader I find the following anomalies: Total width of page outline: 5 7/16 in. Width of actual text block: 4.5 in approx. (this is OK.) Width of text block outline: 3 29/32 in (text overlaps block outline.) And so on. There are gaps between the margin outlines and the text block outline. The margin outlines are the wrong size. When I put the document in final form with \setuppapersize{bok][bok] and comment out \showframe Then the text block is not quite centered: the left margin is smaller than the right margin. Using Xpdf instead of Acrobat Reader shows the same anomalies. Changing marginwidth to margin shows the same anomalies. and so on. -- John Culleton Able Typesetters and Indexers http://wexfordpress.com
