FLEXOGRAPHIC PRINTING METHOD AND FLEXOGRAPHIC PRINTING APPARATUS |
摘要 |
The present invention relates to a flexographic method of printing and a flexographic printing apparatus whereby the repeat length is greater than the circumference of the printing roller. This may be achieved by controlling the rotation of the printing roller as a non-printing zone of the printing roller passes a moving web such that an associated non-printed region formed on the web has a length that is greater than the non-printing zone. The rotation of the printing roller may be controlled by suspending the rotation of the printing roller or reducing the speed of rotation when the non-printing zone is in registration with the web and then increasing the speed of rotation to a predetermined printing speed as a printing zone of the printing roller comes into registration with the web.
