Abstract

The application relates to a printing control method, which comprises the steps that a printing control system feeds back printing end information of a current layer to an image monitoring system, the image monitoring system collects and identifies a current layer printing image, then the current layer printing image defect information is fed back to the printing control system, if the current layer printing image is fed back to be defect-free, printing work is continuously executed, when the image monitoring system feeds back that the current layer printing image is defect-free, the printing control system controls a spray head to move to a test page printing area to execute spray head state detection, and receives spray head state information fed back by the image monitoring system, the printing control system executes corresponding printing image defect compensation printing according to the defect information and the spray head state information fed back by the image monitoring system, and the printing control system repeatedly executes the printing operation until the whole printing task is completed. The application also relates to a printing control system and a computer readable storage medium. The problem that the shower nozzle was blockked up or is damaged in order to ensure to once only accomplish whole printing work operation can be solved to this scheme.

Description

Printing control method and system Technical Field The present invention relates to the field of printing methods, and in particular, to a printing control method and system. Background Inkjet toner (3 DP) printing technology is an advanced manufacturing technology that relies on precise control of a software system to enable precise movement of the nozzle head in accordance with two-dimensional data of the model cross section. During printing, the spray head can selectively spray the adhesive at specific positions, and the adhesive can bond powder materials together, and the powder materials are stacked layer by layer to finally form the required three-dimensional model. However, in practical applications, inkjet toner printing technology also faces a number of challenges. Since the adhesive generally has a certain viscosity, this may cause a problem in that part of the nozzle holes are blocked or damaged during long-term use of the nozzle. When the nozzle is blocked or damaged, it cannot spray the adhesive at the corresponding position, so that a blank block which cannot spray the adhesive is formed in the printing process. These blank blocks, after being formed by stacking, may cause a decrease in strength of the print model and may generate various forming defects such as cracks, deformation, and the like. More seriously, these problems are often difficult to find in time during the printing process. Blank blocks due to clogged or damaged nozzles are usually observed only after printing is completed, which makes the problem finding and solving very difficult. Therefore, how to effectively solve the problem of nozzle blockage or damage and improve the strength and forming quality of the printing model becomes a key problem to be solved in the current ink-jet powder-sticking printing technology.
