The patterns and text on the glass bottle can be printed in the following ways:
1. It can be printed on by silk screen
Silk-screen printing belongs to stencil printing, and silk-screen printing is called the four major printing methods together with offset printing, embossing and gravure printing. Hole printing includes transcription, perforated pattern, spray and screen printing, etc.
The principle of stencil printing is: the printing plate (the perforations that can pass ink are made on the base of the paper film plate or other plates) during printing, there will be a certain pressure to transfer the ink to the substrate (paper, ceramics, etc.) through the perforations of the stencil. Etc.), the corresponding image or text is formed on the substrate.
2. It can be printed on by roasting flowers
Another method of glass bottle pattern printing-baking flowers, this is usually after the pattern decoration on the bottle body, but also enter the oven for firing, and finally the pattern or text is firmly attached to the glaze surface of the porcelain .
3. Thermal transfer
Thermal transfer is an emerging printing process. The process printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing uses halftone printing to pre-print the pattern on the surface of the film. The printed pattern has rich layers, bright colors, ever-changing, small color difference, and good reproducibility. , Can achieve the effect of the designer’s requirements, and is suitable for mass production.
The transfer process transfers the exquisite pattern on the transfer film to the surface of the product through a heat transfer machine (heating and pressure). After forming, the ink layer and the product surface are integrated into one body, which is vivid and beautiful, greatly improving the quality of the product.
