Production method and production line for ceramic tiles in which fixed patterns dynamically printed through rubber-covered rollers correspond to ink-jet patterns dynamically printed through ink jetting

Abstract

The invention relates to the technical field of ceramic decoration, in particular to a production method and a production line for ceramic tiles in which fixed patterns dynamically printed through rubber-covered rollers correspond to ink-jet patterns dynamically printed through ink jetting. The method includes the steps that a, the printing programs and sequences of a rubber-covered roller printing machine and a digital ink-jet printing machine are preset; b, one corresponding fixed pattern is printed in the fixed region of a ceramic tile blank by each rubber-covered roller; and c, one corresponding ink-jet pattern is printed in the fixed region of the ceramic tile blank, wherein the sequences of the step b and the step c can be interchanged, the step d further exists between the step b and the step c, and the fixed patterns dynamically printed through the rubber-covered rollers correspond to the ink-jet patterns dynamically printed through ink jetting. The fixed patterns dynamically printed through the rubber-covered rollers correspond to the ink-jet patterns dynamically printed through ink jetting one to one, pattern textures can be correspondingly overlapped, and therefore multiple ceramic decorative tiles with fixed pattern textures, special process effects and textures can be produced at a time.

Description

Technical field [0001] The invention relates to the technical field of ceramic decoration, in particular to a ceramic tile production method and production line in which a fixed pattern dynamically printed by a rubber roller corresponds to an inkjet pattern dynamically printed by an inkjet. Background technique [0002] After decades of development in my country's building ceramics industry, the production and manufacturing level has been greatly improved, and the product quality and decoration level have been comparable to those of advanced foreign countries. In the decoration technology of ceramic tile surface, especially the pattern decoration, its development process has mainly gone through three stages: namely, screen lithography decoration, rubber roller printing decoration and 3D digital inkjet printing decoration. Among them, 3D digital inkjet printing decoration technology has become the mainstream of current ceramic tile product pattern decoration technology, while the ...

[0007] 3. Rubber roller combined with digital inkjet printing: the number of combinations and the order of front and rear decoration are not limited, but most of them are printed with rubber roller in front and digital inkjet printing in the back; conventional rubber roller printing decoration is continuous , will not print a fixed pattern, and the pattern of the rubber roller is also engraved with a circle of connected patterns, so the pattern texture of the rubber roller printing decoration is similar but different, that is, the pattern of each piece of decorated ceramic product is not fixed. There will be differences in the pattern position between the pieces, so the pattern changes between the multi-piece products, the styles are similar, similar but different; because the decorative features of both the rubber roller and the digital inkjet are dynamic printing, so the two The pattern texture of the decoration does not have a corresponding relationship, so it cannot be used as a fixed pattern decoration for positioning

[0008] Therefore, the combination of any two of the above-mentioned different decoration techniques still cannot realize the correspondence between the front and rear decoration patterns, especially for the fixed patterns of some ceramic accessories tiles with strong decoration. A variety of ceramic decorative tiles with fixed pattern textures, special process effects and textures are produced at one time on the production line; in addition, multiple firings (at least twice) are used in the prior art to improve the surface of ceramic tiles The special decorative effect, that is, the process of re-glazing, re-decorating, and then firing in the kiln on the surface of the fired finished ceramic tiles

However, this multi-firing process is mostly used in accessories and ceramic tile products. The process is very complicated and the production cost is high, so it is difficult to be widely used in industry.
