Embodiment Construction

[0062] In this application, the main control computer (referred to as the host) transmits the rasterized master image data to the printing equipment control system, for example: high-speed inkjet printing equipment control system. The host computer passes the size (width*length), number of pages, and generation method of the random position parameters of the image to be randomly extracted to the high-speed inkjet printing equipment control system as parameters; when printing starts, the high-speed inkjet printing equipment control system first according to The set random position parameter generation method generates random position parameter coordinates x, y, and calculates the image data storage location corresponding to the random position parameter coordinates as the address for data reading. The control system starts from the address obtained by calculation, reads the data of a set width image, and further processes it according to the arrangement of the imaging components...

Abstract

The invention discloses a random image processing method and a printing device control system. The random image processing method is applied in the printing device control system and used for obtaining image data on any one of at least one page and comprises the steps of receiving rasterized mother board image data, set length and set width of images required to be extracted randomly and parameters for representing random number generation modes which are sent by a host computer; obtaining random number coordinates and image data memory addresses relevant with the random number coordinates based on the random number generation modes included in the parameters; using the image data memory addresses as starting addresses to begin to read the image data according to the set width and the set length; sending the read image data to an imaging part for imaging.

Description

technical field [0001] The present application relates to the field of digital printing, in particular to a random image processing method and a printing equipment control system. 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 using 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 generates a pulse to squeeze out the ink, and Spray mist ink droplets directly on the surface of the substrate (such as paper) for imaging. Compared with traditional printing methods, digital printing saves the process of plate making and proofing, the steps are simple and fast, and it supports variable data printing. [0003] In addition, since the data needs to be directly t...
