Separation of identical bar codes (same code type/identical contents)
Note If the number n > 1, minimum distances must be provided between the bar codes on the
object, if
• the SMART decoder is to read bar codes that originate from the same code type and
have identical or different data contents
• the standard decoder is to read and distinguish bar codes with the same name
(identical code type and data content)
The necessary calculations are provided in Chapter 10.8.3 Calculating the necessary
capture area for the bar code if several bar codes are read on each object, Page 10-58.
