About Flattermarken
Flattermarken (collation marks) are not data codes but control marks on the spine of folded sheets: each sheet moves the mark one position, letting the bookbinder verify the sequence of signatures.
Data format
Digit string; each digit controls position or width of a mark.
Example: 11099
Linear Codes
One-dimensional barcodes consist of parallel bars and spaces of varying width. They are the industry standard for logistics, warehousing, inventory, tickets and product marking, readable by any laser or camera scanner.
