| Abstract: | In order to improve the printing quality, a high precision system for measuring the surface position deviation of the printer cylinder at high revolution speed is presented. The design concept, structure, function and software design of the system are introduced. The design of the barcode and the method for measuring the position deviation of the surface with phase locking circuit are discussed. The experimental results show that the system can identify the position deviation down to 10 μm and measurement error is less than 3 μm. |
