Ink-jet printing defect detection method and ceramic tile production process

Abstract

The invention relates to an ink-jet printing defect detection method and a ceramic tile production process. The detection method comprises the steps of (1) designing an ink-jet printing pattern of a green body, setting color strips on at least one side of the pattern, wherein the color strips comprise monochromatic strips or/and colored strips, the color of the monochromatic strips is the color ofa single color channel in an ink-jet printer, and the color of the colored strips is permutation and combination of colors of multiple color channels, and acquiring a pattern with the color strips; (2) performing ink-jet printing, that is, ink-jet printing the pattern with the color strips on the surface of a tile blank; and (3) distinguishing the grayscale, that is, distinguishing whether the grayscale of the same color in the color strips printed at the surface of the tile blank is consistent or not, wherein it is indicated that the ink-jet printer has a fault if the grayscale of a part ishigh or low, and performing detection and adjustment on the ink-jet printer. According to the detection method provided by the invention and the ceramic tile production process, the monitoring is simpler and easier, the efficiency of ink-jet printing is improved, a problem of degradation of a large quantity of products is avoided, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a detection method for inkjet printing defects and a ceramic tile production process thereof. Background technique [0002] In the existing preparation process of ceramic tiles, in order to make the decorative effect of the tiles more three-dimensional and rich in variety, it is usually formed by firing at high temperature after using 3D inkjet printing technology to decorate the pattern on the bottom blank. Since the pattern design of the brick surface is converted into a grayscale file by an inkjet machine for printing, and when the grayscale of the layout design is uniform or the local grayscale is large during the printing process, the nozzle of the inkjet printer is prone to failure. Continuous drawing or lack of flowers, but because of the extremely thin and shallow defects, it is not easy to find the printed pattern by direct observation of the naked eye. Of...

Problems solved by technology

Since the pattern design of the brick surface is converted into a grayscale file by an inkjet machine for printing, and when the grayscale of the layout design is uniform or the local grayscale is large during the printing process, the nozzle of the inkjet printer is prone to failure. Continuous drawing or lack of flowers, but because of the extremely thin and shallow defects, it is not easy to find the printed pattern by direct observation of the naked eye. Often it can only appear after being fired out of the kiln. Due to the failure to find out in time, a large number of products will be degraded. production problems are unavoidable

[0003] The solution of existing inkjet machine equipment for this problem is to increase the inter-spray function between bricks, that is, to spray 100% grayscale ink on the belt between bricks and bricks for detection, but due to its ink The cost is high, the amount of waste is large, which leads to an increase in production costs, and the inspection and adjustment of faults are inefficient, resulting in low production efficiency, and it is still impossible to efficiently detect defects in inkjet printing
