# TeX: Justification with no hyphenation

I’ve been reading a copy of 1984 by George Orwell, published by Fingerprint publishing — a beautifully typeset one. Already into half of Part II, but that’s when I noticed that the book is typeset with full justification sans any hyphenation. Incidentally I was typesetting something else, which probably is the reason I noticed it now. And I wanted to typeset my article the same way, with full justification but no hyphenation.

Biggest strength of TeX is its line, paragraph and page breaking algorithms where hyphenation plays a big part. Thus removing hyphenation means taking away a lot of those advantages. In any case, there are seemingly multiple ways to do it. From the TeX FAQ:

Use `hyphenat` package with

``\usepackage[none]{hyphenat}``

or set `\hyphenpenalty` and `\exhyphenpenalty` to 10000. These avoided hyphenation, but justification was bad – there were long words extending beyond the right margin. So moved on to next solution:

``````\hyphenchar\font=-1
\sloppy``````

This one kept hyphenation to the minimum with justified text, but didn’t fully avoid it. And it would work only for text with current font. `\sloppy` sets `\tolerance` and `\emergencystretch` to large values.

And the last one, which provided full justification with no hyphenation is:

``````%\tolerance=1
\emergencystretch=\maxdimen
\hyphenpenalty=10000``````

The `\tolerance` parameter sets how much badness is allowed, which influence paragraph/line breaking. `\emergencystretch` is the magical parameter which stretches text over multiple passes to balance the spacing. Setting `\hyphenpenalty` to infinite value actually has better effect than setting `\tolerance`.
