A System for Graphic Personalisation of Cards and Paper Sheets
The article presents the structure and operation of the developed system for graphic personalisation of cards and paper sheets. The system is responsible for the input of unique graphics in the form of prints corresponding with suitable data recorded in the memory of a microprocessor. In the verification process, an electronic record is compared with alphanumerical information, and the conformity of digital graphics with the print is checked. The system was used in the construction of a process line for producing RFID-secured documents. The system has a modular structure and is composed of two modules responsible for the prints and automatic verification of graphic personalisation. The printing module enables the application of the print in the form of alphanumerical signs or unique graphic symbols and a barcode, which is conducted according to the structure of the database from which information on personalisation is obtained. The verification module compares the electronic record from the microprocessor with alphanumerical information and checks whether digital graphics agree with the print. Printing is performed using an inkjet printhead, whereas for the verification process, a digital line scan camera is applied. Mechatronic positioning systems enable the printhead and camera shift freely along the print and inspection area and allow changes in positioning speed parameters.
