It may also be discovered, when designing a variable print document, that different quantities of variable text must fit in a text field with static text. The size of the text field must again be considered in order to accommodate the largest possible entry of variable text in the field.

Because of the lower resolution of some digital printing equipment as compared with the potential resolution of conventional printing equipment, there are several points to consider:

• Extremely small type sizes may not print clearly with digital technology.
  
  
• Type should not be set less than 6 points in order to remain legible.
  
  
• Reverse type should not be less than 9 points. Avoid use type faces containing serifs for reverse printing unless it is over 12 points in size.
  
  
• There are many typefaces including some of the sans-serif styles that do not reproduce well unless the resolution reaches at least 1,200 spi. It is best to stay with a group of fonts that have been specially selected for digital print equipment.
