Preparing a Type 1 font

The process of installing a Type 1 font set is rather convoluted, and we will deal with it in two chunks: first (in the present answer) preparing the font for installation, and second installing a Type 1 font).

Many fonts are supplied in (La)TeX ready form: such fonts need no preparation, and may be installed immediately.

However, if you purchase a font from a Type foundry (either direct or via one of the web stores), you are likely to need to ‘prepare’ it for use with (La)TeX. The rest of this answer discusses this preparation.

Having traversed this list, you have a set of font files ready for installation.
