This is often thought to look +odd, but it is quite right. +<p/>The idea is that the typographic urge for symmetry should also apply +to margins: if you lay an even numbered page to the left of an +odd-numbered one, you will see that you’ve three equal chunks of +un-printed paper: the left margin of the even page, the right margin +of the odd page, and the two abutting margins together. +<p/>This is all very fine in the abstract, but in practical book(let) +production it only works “sometimes”. +<p/>If your booklet is produced on double-width paper and stapled, the +effect will be good; if your book(let) is produced using a so-called +“perfect” binding, the effect will again be good. +<p/>However, almost any “quality” book-binder will need some of your +paper to grab hold of, and a book bound in such a way won’t exhibit +the treasured symmetry unless you’ve done something about the margin +settings. +<p/>The packages recommended in +“<a href="FAQ-marginpkgs.html">setting up margins</a>” mostly have provision for +a “binding offset” or a “binding correction” — search for +“binding” in the manuals (<i>vmargin</i> doesn’t help, here). +<p/>If you’re doing the job by hand (see +<a href="FAQ-marginmanual.html">manual margin setup</a>), the trick is to +calculate your page and margin dimensions as normal, and then: +<ul> +<li> subtract the binding offset from <code>\</code><code>evensidemargin</code>, and +<li> add the binding offset to <code>\</code><code>oddsidemargin</code>. +</ul> +which can be achieved by: +<blockquote> +<pre> +\addtolength{\evensidemargin}{-offset} +\addtolength{\oddsidemargin}{offset} +</pre> +</blockquote><p> +(substituting something sensible like “<code>5mm</code>” for +“<code>offset</code>”, above). +<p/>The above may not be the best you can do: you may well choose to +change the <code>\</code><code>textwidth</code> in the presence of the binding offset; but +the changes do work for constant <code>\</code><code>textwidth</code>. +<p/><p/><p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=gutter">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=gutter</a> +</body> |
