Technical Field

The present invention relates generally to laser printing (with 3D or relief effects) on glass articles.

Background

Laser printing is a known technique for printing four colors of CMYK (cyan, magenta, yellow, and black) on a surface of an object, and is performed by irradiating the surface of the object with a laser beam. This technique is limited to fibrous substrates such as paper, plastic or metal. Color printing on glass can only be achieved by silk-screening. Color printing is also limited to output of several colors, and the image definition of the picture cannot be completely reflected.

Other known solutions are water conversion or watermarking by means of a water conversion printing paper solution as disclosed in japanese patent No. JP2009083281 and chinese patent No. CN 103042875 a. However, the above printing requires many steps and cannot reproduce the color and image clarity of a photograph. In addition, the printing surface of the technical scheme is smooth and flat, and the printing effect of 3D or embossment can not be realized like the printing method.

Therefore, the invention can provide a glass product which overcomes the defects of the prior art that the direct laser irradiation and the color printing are carried out on the surface of the glass product;

Laser printing a picture on a glass article comprising: a glass article 20, a composition coating 24 applied to said glass article 20, at least one printing device 26 printing a color toner onto said composition coating 24. The printing device 26 receives picture data files or format files, such as raster and/or vector files like JPG, GIF, PNG, BMP, TIFF, SVG, and the like, from a computer device 28, distinguished by dashed arrows, and prints color toner onto the composite coating 24 proximate to the coating. Optionally, a layer of acidic or basic solution 22 may be applied between the glass article 20 and the composition coating 24.

The laser printing is preferably selected from color printing including CYMK (cyan, yellow, magenta, and black) color toner; however, monochrome or color printing, or a combination of both, may be applied to the surface of the glass article. Preferably, the glass article is a bottle, a mug or the like with a flat, curved or non-flat surface. Printing device 26 is a laser printing device, preferably one that can print image resolutions greater than 50 pixels per inch (118 pixels per MM). However, other image resolution devices may be suitable as long as clear pictures can be printed.
