For almost thirty years in pharmaceutical packaging the identity and the correct matching of the packaging media to the pharmaceutical code has been assured. Thus a system was born, which for the first time in the world guaranteed thorough product identification right across the board in fast processing by means of a bar code - and for an entire division of industry.
However, the pharmaceutical code is certainly also a child of its time. Current technologies have enabled essential improvements to be made.
Data Matrix is able to encode data in any desired form and in almost any desired amount. A complete DIN A4 page could be accommodated. In manufacturing processes this is not necessary, where space problems play a different role.
This illustration shows the difference very impressively - Coding space requirement for the same print requirements:
This has always been the greatest challenge in the field of pharmaceutical packaging: The paper folding automat.
The adjacent illustration shows the solution. Data Matrix reading under the stack using an angled optical system and on the reverse side during the traverse. The code has 16 modules and a data content of 16 alphanumeric characters. A module size of 0.4 mm was chosen. This guarantees perfect reading results, even if the paper quality is poor or the printing is not optimal.
Optical and sensor systems, light and electronics - all housed in a 25 x 25 x 80 (mm) package!. The world's smallest laser of its type. 300 packaging slips in DIN A5 format per minute, resulting in traverse speeds of 2 meters per second during reverse side reading. And this performance is achieved without reading errors. The installation and control conditions are similarly favorable, as is well known from decades of pharmaceutical code reading. Reading systems for cardboard carton packaging and labeling are also available. The complete system is operated and controlled centrally via an intelligent industrial terminal.
