  Quotations
  You can specify the type size below which text will be greeked in the Preferences dialog box. Designers often prefer to use greeked text in rough layouts because it helps the client focus on the design rather than on the words.

  If text gets smaller than this value, [Adobe] Illustrator shows the text blocks as gray bars, an operation called greeking. Both type size and view size figure into the equation, so that 6-point type greeks at 100-percent view size and 12-point type greeks at 50 percent. Greeking speeds the screen display because gray bars are easier to draw than individual characters.
