Embodiment Construction
[0024] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0025] This patent provides a variety of parallel schemes, and the different expressions belong to the improved scheme based on the basic scheme or the parallel scheme. Each scheme has its own unique characteristics.
[0026] When the start-up printing speed does not exceed 50m / min and the pressure roller of the color group to be operated is in the pressed state, a rapid registration technology is carried out to realize overprinting in one step. This technology adopts the method of color mark detection after printing. By detecting the position of the color mark of the current color and the previous color, the phase difference between the two is calculated, and the ser...
