| Abstract: | A print online monitoring system based on embedded DSP was introduced. Ink dosage adjustment was realized through getting the signal in the controlling color bar by CCD camera, the BP network model transformation of the signal to CYMK four color inks, and the calculation of dosage difference. It was proved by experiments that this system can realize real-time control of printing process and efficiently solve the shortcomings of offline monitoring. |
