The core set of delta-hinted fonts include:

• Courier 10 roman, italic, bold, and bold italic
  
  
• Dutch 801 roman, italic, bold, and bold italic
  
  
• Swiss 721 roman, italic, bold, and bold italic
  
  
• Symbol Set

Delta hinting involves fine tuning fonts so that they look good on the screen, even at small point sizes on low-resolution devices. Delta-hinted fonts assure the digital clarity of text no matter where it is being displayed. The fonts are targeted for use in applications and devices that rely on the digital displaying of information at low resolutions or small sizes, such as handheld devices, personal digital assistants, and other embedded systems and information appliances.

In the example below, the top line of each point size is not delta-hinted. The second line is the clean, delta-hinted version.

With delta hinting, the result is fine-tuned text that is easier to read, particularly at small point sizes and on low resolution devices such as computer monitors.
