The Code 16K bar code is a multiple-row bar code that can encode the full ASCII character set below ASCII 128. It uses existing UPC and Code 128 character set patterns. Up to 77 full ASCII characters or 154 numeric characters can be encoded. These characters are encoded into 2 to 16 rows. Each row is divided by a separator bar. The top and bottom of the symbol also have separator bars that extend to the ends of the minimum quiet zones.
The Code 16K is similar to Code 128 in that you can choose between three subsets of Code 16K directly or you can choose Code 16K Auto for auto switching mode. When you select Code 16K Auto, if the bar code has four or more consecutive numbers, the numbers are encoded in double-density mode. This means that two numbers are encoded into one character width, making the size of the bar code smaller. The Code 16K bar code has three forms of error detection. Parity is checked for each character, start and stop characters are used to identify each row, and two checksum characters are always appended to the end of the bar code.
