Problems solved by technology
This method of operation is time-consuming and labor-intensive, and the adjustment period is long. When there is an urgent need to change production or when production fluctuates, the plate alignment efficiency cannot meet the production requirements, which seriously affects the appearance quality of the produced products.

Embodiment Construction
[0049] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0050] A kind of on-line version matching method for tile inkjet printing of the present embodiment, such as figure 1 shown, including the following steps:
[0051] Step A, scanning the standard part and identifying the grayscale of each channel to form a first standard grayscale file;
[0052] Step B, scanning the production piece and identifying the grayscale of each channel to form a first production grayscale file;
[0053] Step C, comparing the first production grayscale file with the first standard grayscale file, and calculating the grayscale difference of each channel in the first production grayscale file;
[0054] If the grayscale difference of each channel in the first production grayscale file is less than the first threshold, then the current inkjet printing parameters are not adjuste...

The invention discloses an on-line type edition comparison method for ceramic tile ink-jet printing and a production system using the on-line type edition comparison method. The on-line type edition comparison method comprises the steps that step A, a standard part is scanned and all passage grayscale is identified out, and a first standard grayscale file is formed; step B, a production part is scanned and all the passage grayscale is identified out, and a first production grayscale file is formed; and step C, comparison is performed on the first production grayscale file and the first standard grayscale file, and the grayscale difference value of all passages in the first production grayscale file is calculated. By means of the on-line type edition comparison method for the ceramic tile ink-jet printing and the production system using the on-line type edition comparison method, the on-line type intelligent edition comparison method is realized, the nondeterminacy and instability of manual edition comparison judgement are avoided, when the ceramic face colour of the production part generates deviation, the production part can be rapidly identified out, and a first adjustment grayscale file can be immediately generated to adjust the grayscale of ink in all the passages, the edition face of the subsequent production part is made to be consistent with that of the standard part, loss is reduced, and the edition comparison efficiency and the edition comparison accuracy of the ceramic tile ink-jet printing are greatly improved.
Description
technical field [0001] The invention relates to the field of building ceramics production, in particular to an online plate-setting method for tile inkjet printing and a production system using the same. 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 inkjet printing technology to decorate the pattern on the bottom blank. Due to the fluctuation of ink and glaze color and the change of kiln, the color of the tile layout will change. Therefore, it is necessary to check the version of the fired tiles, that is, the version check personnel can identify the production parts by the naked eye, and judge the production parts based on the experience of color sense. Then adjust the gray level of the ink in each channel in the inkjet machine, so that the subsequent production parts are closer to...
