A headline style that works just fine in a magazine spread would not necessarily work on a poster. A magazine is always viewed straight-on at arms length, so letter spacing can be as tight as you like and the words will still be readable. A poster is, more often than not, viewed obliquely, which distorts the type to some extent. Here, a little extra letter spacing helps identification of the individual characters, and hence the words.
Designing for a computer screen has its own set of problems. Add to these the elastic nature of a Web page, which has to work across different computer platforms and screen sizes, and the problems get even worse. It is the designer’s job to understand these issues and to address them — to maintain some kind of control when everything else is shifting.
The SeveNet font family is no longer available from this site, but may be available from the Fountain Type Foundry in Sweden. As with MINI 7, it is a 7-point Macintosh screen font. It has no PostScript or TrueType printer font and no lowercase characters. The PC version is a regular TrueType font. You can use these fonts at multiples of 7 points (14, 21 etc) if you want a deliberately pixelated look. You should do this in Photoshop with anti-aliasing turned off.
