Hello This is my page: \definepapersize[argento][width=20cm,height=28cm] \setuppapersize[argento][A3] \setuppagenumbering[alternative=doublesided,location=] \setuplayout[location=middle,marking=on,textwidth=150mm] And everithig is fine, but headers are not aligned with text. Also, I use 2 columns in most of the book, but 4 chapters uses 3 columns. I use \startcolumns[n=2, balance=yes,distance=8mm] or \startcolumns[n=3, balance=yes,distance=5mm] In two columns is ok, but in 3 columns, all the 3 columns donŽt fit the whole textwidth, I mean, the sum of the 3 columns width plus the 2 intercolumns space are less (about 1cm) than 150mm, as setuplayout says. Thankyou very much. _________________________________________________________________ Express yourself instantly with MSN Messenger!
