Image-forming block synchronization method in single PASS digital printing device, synchronizer and print device thereof

Abstract

The invention discloses an image-forming block synchronization method in single PASS digital printing device, comprising: printing undertaker is ensured to reach set standard; synchronous processing is carried out on a first image-forming block of each image-forming block group according to the set standard; in each image-forming block, except the first image-forming block, synchronous processing is carried out on the next image-forming block in sequence by taking the previous image-forming block which completes the synchronous processing as a standard on the motion direction of the print undertaker. The method of the invention can simplify the synchronization method and can accurately control imaging moment of each image-forming block to ensure real-time imaging. The invention also discloses an image-forming block synchronizer in the single PASS digital printing device and a single PASS digital printing device.

Description

technical field [0001] The invention relates to the field of digital printing, in particular to a method and device for synchronizing imaging components in single-pass digital printing equipment and printing equipment. Background technique [0002] Digital printing is a printing technology that has developed rapidly in recent years. It is a way to directly transmit, process and print data. For digital printing equipment that uses on-demand inkjet printing, the imaging component is under the control of the control system. When the surface of the substrate (such as paper) reaches a predetermined position, the piezoelectric crystal in the nozzle will squeeze out the ink and send it directly to the The surface of the substrate (such as paper) is sprayed with mist ink droplets to form an image. In digital printing equipment, the data is directly transmitted from the computer to the imaging component for imaging. Therefore, the control system in the digital printing equipment mus...

Problems solved by technology

[0006] The number of imaging components in a single PASS high-speed digital printing device depends on the required width of the equipment, DPI (dot per inch, dots per inch) resolution, and the width and resolution of a single imaging component. Generally speaking , there will be many objects controlled by the control system, that is, imaging components. If all imaging components are synchronized with the same direct reference, each imaging component needs to be timed from the time when the substrate reaches the same direct reference. , the timing of the imaging component that is far away from the reference is too long, and errors are prone to occur. It is difficult to ensure that the printing body can be accurately printed when it reaches the imaging component, which affects the real-time performance of synchronous processing; and the physical width of each imaging component is different. It will also affect the accuracy of synchronous processing; multiple imaging components enter the timing state from when the substrate reaches the reference until printing processing, consuming a lot of system resources
