Adobe Type 1 Font (PFB)
The Adobe Type I Font (PFB) is a file format that stores Adobe Type 1 fonts. Most Type 1 fonts are single master fonts that permit only style editing; for example, Roman, italic, bold. A single master Type 1 font contains two files: a Printer Font Metrics (PFM) file and a Printer Font Binary (PFB) file.
Some Type 1 fonts are also available in multiple master format. You can customize design elements of multiple master fonts such as weight, width, style, and optical size. A multiple master base font is the multiple master font itself, from which you create variations called multiple master instances. A multiple master base font is composed of a PFM file, a PFB file, and a Multiple Master Metrics (MMM) file. A multiple master instance is composed of a PFM file and a PostScript Printer Stub (PSS) file.

For best results, avoid intersecting lines. Any object in your character should lie completely inside or outside of others, as shown in the following example.
