Greeking
Method of displaying small text by software programs. Because some text is too small to display on monitors, fake characters or gray lines are used to display text.
Good examples of where you are likely to see greeking is in a computer
game that shows text in a book as small lines or text and in a print preview.
In the picture to the right, is a good example of greeking that helps show the
overall layout of the page, but for the most part cannot be read.
