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...

Abstract

The invention relates to the field of electronic-shaft gravure pressing, in particular to a quick register method for an electronic-shaft gravure press, mainly overcoming the defects of low precision,low efficiency and the like of existing alignment technology utilized by the conventional presses. According to the method, a post-print color patch test process is carried out, particularly, position of the current color patch and the previous patch is detected by setup of printing (printing in sequence or inverted sequence), and phase difference of the current color patch and the previous colorpatch is calculated, further, a servo motor of a current color cell is controlled directly, a press roll is lifted under control while a printing plate phase position is adjusted in place rapidly bya set adjusting speed, and then the press roll is recovered into a pressing state automatically. By the quick register method, any new plates can be put into printing production process after being set up while phase position of the plates is stored, thus, application efficiency is high; besides, short alignment time is needed, fewer wastes are formed, pre-alignment precision is improved, auxiliary work time is shortened, and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic axis gravure printing, in particular to a fast alignment method for an electronic axis gravure printing machine. Background technique [0002] With the increasingly fierce competition in the printing market, modern printing machines are developing in the direction of high quality, high precision, high speed and high automation. A printing machine includes multiple color group units, and each color includes a printing roller and an embossing roller. After the printing machine installs and replaces the master roller, in order to achieve faster register accuracy and reduce the automatic registration range, it is necessary to turn the master roller of each color group to the same position. At this position, the patterns printed by the plate rollers of each color group on the substrate are almost completely coincident, and this process is called pre-registration, that is, plate alignment. After pre-registra...
