deviation from a 90° relation between row
and column.

15° Deviation from Ideal Row/Column
Symbol Contrast
is the value difference between light and dark
symbol elements, and between the quiet zone and perimeter
elements.
This example shows a low-contrast symbol. The dark elements
(etched) and the light elements (the substrate’s surface) are too
close in value, which undermines readability.
The
Quiet Zone
is an unmarked space of at least one element in
width surrounding the symbol, required for symbol readability.
The red box in the example represents the outer perimeter of the
minimum
Quiet Zone requirement. The Quiet Zone can be any
amount greater than one element in width, but any Quiet Zone
width less than one element will make the symbol difficult or
impossible to read.
